#### Library Changes

1. Functions to configure coverage, profile, and profile=gc reports were added.

   While they have been accessible through extern(C) linkage for a while, the functions to configure coverage, profile, and profile=gc reports where added to core.runtime.

   Functions | Decscription
   --- | ---
   dmd_coverSourcePath | Set the directory which contains the source files.
   dmd_coverDestPath | Set the directory where to write the -cov reports.
   dmd_coverSetMerge | Set whether or not to merge results with existing -cov reports.
   trace_setlogfilename | Set the output file for the -profile report.
   trace_setdeffilename | Set the output file for the optimized -profile linker script.
   profilegc_setlogfilename | Set the output file for the -profile=gc report.

   Note that these functions are specific to dmd, and might not be available on other compilers.

List of all bug fixes and enhancements in D 2.068.

#### Compiler Changes

1. Warning: Change in helper function generation might cause link error.

   In order to fix Issue 14828 compiler helper functions for array bounds checking and assert are now generated only once when a module is compiled, not everytime they are used. This may lead to link errors when using a module without compiling and linking against it.

   If you encounter link errors like

       undefined reference to '_D5mylib5mymod7__arrayZ'

       undefined reference to '_D5mylib5mymod8__assertFiZv'

       undefined reference to '_D5mylib5mymod15__unittest_failFiZv'

   then you're not compiling and/or not linking the module mylib.mymod.
2. The new -profile=gc switch enables profiling memory allocation.

   When compiling with -profile=gc dmd will instrument GC allocations to be traced by the runtime. The runtime accumulates the traces and writes a report to the file profilegc.log upon program termination.

   Example:

       bytes allocated, type, function, file:line
            171	immutable(char)[] example.concat example.d:4
             24	closure D main example.d:18
             16	example.Klass D main example.d:20

   Note: GC allocations using the core.memory interface are not profiled.

3. unittest blocks no longer parsed unless -unittest is specified:

   When the unittest code is not necessary, it will be merely analyzed as the tokens enclosed with paired braces, to speed up compilation speed.

       unittest { auto r = test(); assert(r); }
       // If you don't specify -unittest, no AST generated for the unittest block.

       unittest { the contents is just ignored. }
       // Since 2.067: this had caused parsing error.
       //  From 2.068: no error happens, because it's equivalent with:
       enum unittest_code = q{ the contents is just ignored. };

#### Language Changes

1. Many phobos functions were rangified.

   Many phobos functions that allocated GC memory were changed to support ranges or were complemented by an alternative supporting ranges. Using ranges often eliminates GC allocations.

       setExtension("foo.jpg", ".png"); // allocates a new string
       withExtension("foo.jpg", ".png"); // returns a range without allocating

   Rangified Functions:
   Module | Functions
   --- | ---
   std.algorithm.comparison | levenshteinDistance
   std.path | asAbsolutePath asNormalizedPath asRelativePath chainPath dirName driveName filenameCmp globMatch isValidFilename isValidPath pathSplitter rootName stripExtension withDefaultExtension withExtension
   std.string | centerJustifier chomp chompPrefix chop column detabber entabber indexOf leftJustifier makeTransTable rightJustifier soundexer strip stripLeft stripRight
   std.uni | asCapitalized asLowerCase asUpperCase

2. pragma(inline) was added:

   A new pragma was added for more fine-grained control of inlining. It must be used together with the -inline switch.

       pragma(inline, true) // errors if function isn't inlined
       int double(int val) { return 2 * val; }

       pragma(inline, false) // never inline
       int double(int val) { return 2 * val; }

   Read the documentation for more details.

3. Attributes for auto return function are now inferred.

   Just like templated functions, functions with an auto return type must always have a function body. The compiler was changed to take advantage of this fact and now also infers attributes for them.

       auto foo()() {} // template function
       auto bar() {}   // non-template function without return type
       void baz() {}   // non-template function with return type

       static assert(is(typeof(&foo!()) == void function() pure nothrow @nogc @safe));
       static assert(is(typeof(&bar) == void function() pure nothrow @nogc @safe));
       static assert(is(typeof(&baz) == void function()));

4. Indexed type tuples can now be followed by dot identifiers.

   A parsing limitation was lifted and it's now possible to use an indexed type tuple followed by dot identifiers as typename.

       alias TypeTuple(T...) = T;

       struct S
       {
           alias T = int;
           alias U = TypeTuple!(long, string);
       }

       alias Types = TypeTuple!(S, S);

       struct X(Types...)   // used tuple parameter
       {

           Types[0].T a;     // Types[0] == S, then typeof(a) == S.T == int
           Types[0].U[1] b;  // Types[0].U == S.U, then typeof(b) == S.U[1] == string
       }
       alias x = X!Types;

5. Support template parameter deduction from function default arguments:

   When performing IFTI templated types can now be deduced from a parameter's default argument. This avoids a redundant and error prone declaration of the default type.

       void previously(T=int)(T t = 0) { } // it was necessary to also specify a default type
       void now(T)(T t = 0) { } // the default type can be deduced from the default argument as int
       void main() { previously(); now(); }

6. Invalid reinterpret casts can be detected in the frontend.

   Invalid reinterpret casts are now detected in the compiler frontend instead of the backend. This allows to check for possible reinterpret casts during compile time and improves the error messages for invalid casts.

       pragma(msg, is(typeof({ void* x; auto y = cast(void delegate())x; })));
       // Since 2.067: it prints 'true'
       //  From 2.068: it prints 'false'

       void test() { void* x; auto y = cast(void delegate())x; }
       // Since 2.067: it had reported internal compiler error "Error: e2ir: cannot cast ..."
       //  From 2.068: it reports proper frontend error.

#### Library Changes

1. GC API calls can now be profiled separately.

   The GC option --DRT-gcopt=profile has been enhanced to accept an additional level 2 that allows profiling API calls grouped by most common operations.

   As this instrumentation has an impact on the GC performance even if unused, you have to recompile the GC module with -debug=PROFILE_API, e.g.

       dmd test.d -O -inline -debug=PROFILE_API -Ipath-to-druntime/src path-to-druntime/src/gc/gc.d
       ./test --DRT-gcopt=profile:2

   The profiling summary will then look like this:

           malloc:  9768628 calls, 531 ms
           realloc: 0 calls, 0 ms
           free:    0 calls, 0 ms
           extend:  1100 calls, 0 ms
           other:   826 calls, 0 ms
           lock time: 160 ms
           GC API: 692 ms
       GC summary:   12 MB,   52 GC  331 ms, Pauses  227 ms <    4 ms API  692 ms

   The malloc function includes time for GC collections. Lock time (GC synchronization) is measured separately and not included in the other times.

2. The AA implementation now uses open addressing.

   The runtime implementation for associative arrays was rewritten and now uses open addressing with quadratic probing and triangular numbers. This is much more cache friendly than the old separate chaining implementation and can result in ~25% faster lookups for big AAs. Also see druntime#1229.

   Note: As the allocation pattern changed (the table is bigger, nodes are smaller) you might see a small drop in performance because the GC manages big allocations less efficiently.

List of all bug fixes and enhancements in D 2.067.

#### Language Changes

1. Destructors for structs allocated on the heap are now invoked.

   Previously, when a struct allocated on the heap was freed, the destructor was not invoked. This is no longer the case, and these destructors will now be invoked before the memory is freed by the GC.

2. asm statements can now be used in pure, nothrow, @nogc, or @trusted code.

   By adding the appropriate attributes to an asm statement you can tell the compiler how that asm code behaves, thus allowing asm statements to be used in pure, nothrow, @nogc, or @safe functions.

       asm pure nothrow @nogc @trusted
       {
           // the compiler does not check the attributes
           ret;
       }

3. package protection attribute can be optionally bound to specified package

   New optional syntax was added for package protection attribute:

       module aaa.bbb.ccc.ddd;

       // accessible from any module with aaa.bbb in qualified path
       package(aaa.bbb) void foo() {}

       // old style, means same as package(aaa.bbb.ccc)
       package void bar() {}

4. Sealed references were added (DIP25)

   In @safe functions it is now required to use return ref to return a reference to a parameter or a field of it.

       @safe:
       ref int fun(ref int a) { return a; } // ERROR
       ref int gun(return ref int a) { return a; } // FINE
       ref T hun(T)(ref T a) { return a; } // FINE, templates use deduction

   See DIP25 for more details.

5. The with statement now observes temporary object lifetime

   A longstanding bug of the with statement was fixed which prevented the idiomatic use of RAII values.

       with (File("output.log", "w"))
       {
           writeln("Content");
       }
       // File is automatically closed

#### Library Changes

1. This release comes with various GC optimizations that make many applications faster.

   A new GC growth policy was implemented that helps to reduce the number of collections by keeping a collection threshold at 2x the size of the used memory. After each collection the used memory and the threshold are recomputed. This allows for an exponential growth of the GC heap, e.g. during program startup, but limits the heap size relative to the actual used memory. The factor 2x is configurable by setting heapSizeFactor.

   The heap traversal during the marking phase is now done using tail recursion with a separate compact state stack. This allows to mark very deep heaps (lists) much faster because the previous recursion limit of 50 is eliminated.

   You can see a list of all improvements here.

2. volatileLoad and volatileStore intrinsics were added.

   Calls to volatileLoad and volatileStore are recognized by the compiler and guaranteed to not be removed or reordered in the same thread.

       void example(uint* address, uint value)
       {
           import core.bitop;

           // store value
           volatileStore(address, value);

           // wait until value takes affect
           while (volatileLoad(address) != value)
           { }
       }

   Note: These intrinsics are currently in core.bitop, but will be moved to core.volatile when volatile is no longer a keyword.

3. Experimental: The garbage collector can now be configured through the command line, the environment or by options embedded into the executable.

   By default, GC options can only be passed on the command line of the program to run, e.g.

       app "--DRT-gcopt=profile:1 minPoolSize:16" arguments to app

   Available GC options are:

   - disable:0|1 - start disabled
   - profile:0|1 - enable profiling with summary when terminating program
   - initReserve:N - initial memory to reserve in MB
   - minPoolSize:N - initial and minimum pool size in MB
   - maxPoolSize:N - maximum pool size in MB
   - incPoolSize:N - pool size increment MB
   - heapSizeFactor:N - targeted heap size to used memory ratio

   In addition, --DRT-gcopt=help will show the list of options and their current settings.

   Command line options starting with "--DRT-" are filtered out before calling main, so the program will not see them. They are still available via rt_args().

   Configuration via the command line can be disabled by declaring a variable for the linker to pick up before using it's default from the runtime:

       extern(C) __gshared bool rt_cmdline_enabled = false;

   Likewise, declare a boolean rt_envvars_enabled to enable configuration via the environment variable "DRT_GCOPT:

       extern(C) __gshared bool rt_envvars_enabled = true;

   Setting default configuration properties in the executable can be done by specifying an array of options named rt_options:

       extern(C) __gshared string[] rt_options = [ "gcopt=initReserve:100 profile:1" ];

   Evaluation order of options is rt_options, then environment variables, then command line arguments, i.e. if command line arguments are not disabled, they can override options specified through the environment or embedded in the executable.

4. byKeyValue was added.

   Built-in associative arrays now have a .byKeyValue method that returns a forward range iterating over key/value pairs.

       void main()
       {
           auto aa = ["a": 1];
           foreach (pair; aa.byKeyValue)
           {
               assert(pair.key == "a");
               assert(pair.value == 1);
           }
       }

5. enumerate was added.

   enumerate enables iteration of ranges with an index variable:

       void main()
       {
           import std.stdio : stdin, stdout;
           import std.range : enumerate;

           foreach (lineNum, line; stdin.byLine().enumerate(1))
               stdout.writefln("line #%s: %s", lineNum, line);
       }

6. handle was added.

   handle enables exception handling in range compositions:

       import std.algorithm : equal;
       import std.range : retro;
       import std.utf : UTFException;

       auto str = "hello\xFFworld"; // 0xFF is an invalid UTF-8 code unit

       auto handled = str.handle!(UTFException, RangePrimitive.access,
               (e, r) => ' '); // Replace invalid code points with spaces

       assert(handled.equal("hello world")); // `front` is handled,
       assert(handled.retro.equal("dlrow olleh")); // as well as `back`

7. An experimental logging system was added.

       import std.experimental.logger;

       void main()
       {
           log("message logging in D");
       }

#### Linker Changes

List of all bug fixes and enhancements in D 2.066.

#### Compiler Changes

1. -w now warns about an unused return value of a strongly pure nothrow function call:

   A discarded return value from a strongly pure nothrow function call now generates a warning.

       int foo() pure nothrow { return 1; }
       void main()
       {
           foo();  // the result of foo() is unused
       }

   With the -w switch, the compiler will complain:

       Warning: calling foo without side effects discards return value of type int, prepend a cast(void) if intentional

2. -noboundscheck has been deprecated in favor of boundscheck=[on|safeonly|off]:

   Confusion over what the -noboundscheck command line option did led to the creation of the new option -boundscheck=[on|safeonly|off] which aims to be more clear while enabling more flexibility than was present before.

   -boundscheck=

   - on: Bounds checks are enabled for all code. This is the default.
   - safeonly: Bounds checks are enabled only in @safe code. This is the default for -release builds.
   - off: Bounds checks are disabled completely (even in @safe code). This option should be used with caution and as a last resort to improve performance. Confirm turning off @safe bounds checks is worthwhile by benchmarking.

   Use -boundscheck=off to replace instances of -noboundscheck.

   Prior to this there was no way to enable bounds checking for -release builds nor any way of turning off non-@safe bounds checking without pulling in everything else -release does.

3. -vgc was added to list GC allocation code positions in the code:

   Prints all GC-allocation points. Analysis will follow the semantics of the new @nogc attribute.

4. -vcolumns was added to display column numbers in error messages:

   Diagnostic messages will print the character number from each line head.

       int x = missing_name;

   Without -vcolumns:

       test.d(1): Error: undefined identifier missing_name

   With -vcolumns:

       test.d(1,9): Error: undefined identifier missing_name

5. -color was added to make console output colored:

   Errors, deprecation, and warning messages will be colored.

#### Language Changes

1. @nogc attribute was added:

   @nogc attribute disallows GC-heap allocation.

       class C {}
       void foo() @nogc
       {
           auto c = new C();   // GC-allocation is disallowed
       }

2. extern (C++, namespace) was added:

   To represent a C++ namespace, extern (C++) now takes optional dot-chained identifiers.

       extern (C++, a.b.c) int foo();

   is equivalent with:

       namespace a {
         namespace b {
           namespace c {
             int foo();
           }
         }
       }

3. Operator overloading for multi-dimensional slicing was added:

   Documentation is here.

   Example code:

       struct MyContainer(E)
       {
           E[][] payload;

           this(size_t w, size_t h)
           {
               payload = new E[][](h, w);
           }

           size_t opDollar(size_t dim)()
           {
               return payload[dim].length;
           }

           auto opSlice(size_t dim)(size_t lwr, size_t upr)
           {
               import std.typecons;
               return tuple(lwr, upr);
           }

           void opIndexAssign(A...)(E val, A indices)
           {
               assert(A.length == payload.length);

               foreach (dim, x; indices)
               {
                   static if (is(typeof(x) : size_t))
                   {
                       // this[..., x, ...]
                       payload[dim][x] = val;
                   }
                   else
                   {
                       // this[..., x[0] .. x[1], ...]
                       payload[dim][x[0] .. x[1]] = val;
                   }
               }
           }
       }
       void main()
       {
           import std.stdio;

           auto c = MyContainer!int(4, 3);
           writefln("[%([%(%d%| %)]%|\n %)]", c.payload);
           // [[0 0 0 0]
           //  [0 0 0 0]
           //  [0 0 0 0]]

           c[1 .. 3,
             2,
             0 .. $] = 1;
           /*
           Rewritten as:
           c.opIndexAssign(c.opSlice!0(1, 3),
                           2,
                           c.opSlice!2(0, c.opDollar!2()));
           */

           writefln("[%([%(%d%| %)]%|\n %)]", c.payload);
           // [[0 1 1 0]
           //  [0 0 1 0]
           //  [1 1 1 1]]
       }

4. __traits(getFunctionAttributes) was added:

   This can take one argument, either a function symbol, function type, function pointer type, or delegate type. Examples:

       void foo() pure nothrow @safe;
       static assert([__traits(getFunctionAttributes, foo)] == ["pure", "nothrow", "@safe"]);

       ref int bar(int) @property @trusted;
       static assert([__traits(getFunctionAttributes, typeof(&bar))] == ["@property", "ref", "@trusted"]);

5. Support template parameter deduction for arguments with a narrowing conversion:

   Implicit Function Template Instantiation will now consider a narrowing conversion of function arguments when deducing the template instance parameter types.

       void foo(T)(T[] arr, T elem) { ... }
       void main()
       {
           short[] a;
           foo(a, 1);
       }

   In 2.065 and earlier, calling foo(a, 1) was not allowed. From 2.066, T is deduced as short by considering a narrowing conversion of the second function argument 1 from int to short.
6. Read-Modify-Write operations on shared variables are now deprecated:

   Examples:

       shared int global;
       void main()
       {
           global++;       // deprecated
           global *= 2;    // deprecated
       }

   Instead you should use atomicOp from core.atomic:

       shared int global;
       void main()
       {
           import core.atomic;
           atomicOp!"+="(global, 1);
           atomicOp!"*="(global, 2);
       }

7. Support uniform construction syntax for built-in scalar types:

   Examples:

       short n1 = 1;
       auto n2 = short(1); // equivalent with n1, typeof(n2) is short

       auto p1 = new long(1);                  // typeof(p1) is long*
       auto p2 = new immutable double(3.14);   // typeof(p2) is immutable(double)*

   The constructor argument should be implicitly convertible to the constructed type.

       auto n1 = short(32767); // OK
       auto n2 = short(32768); // Not allowed, out of bounds of signed short -32768 to 32767

#### Library Changes

1. Duration.get and its wrappers have been deprecated in favor of the new Duration.split:

   Duration.get and its wrappers, Duration.weeks, Duration.days, Duration.hours, and Duration.seconds, as well as Duration.fracSec (which served a similar purpose as Duration.get for the fractional second units) have proven to be too easily confused with Duration.total, causing subtle bugs. So, they have been deprecated. In their place, Duration.split has been added - and it's not only very useful, but it does a great job of showing off what D can do. Whereas Duration.get split out all of the units of a Duration and then returned only one of them, Duration.split splits out a Duration into the units that it's told to (which could be one unit or all of them) and returns all of them. It has two overloads, both which take template arguments that indicate which of the units are to be split out. The difference is in how the result is returned. As with most of the templates in core.time and std.datetime which take strings to represent units, Duration.split accepts "weeks", "days", "hours", "minutes", "seconds", "msecs", "usecs", "hnsecs", and "nsecs". The first overload returns the split out units as out parameters.

       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       short days;
       long seconds;
       int msecs;
       d.split!("days", "seconds", "msecs")(days, seconds, msecs);
       assert(days == 39);
       assert(seconds == 61_202);
       assert(msecs == 1);

   The arguments can be any integral type (though no protection is given against integer overflow, so unless it's known that the values are going to be small, it's unwise to use a small integral type for any of the arguments). The second overload returns a struct with the unit names as its fields. Only the requested units are present as fields. All of the struct's fields are longs.

       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       auto result = d.split!("days", "seconds", "msecs")();
       assert(result.days == 39);
       assert(result.seconds == 61_202);
       assert(result.msecs == 1);

   Or if no units are given to the second overload, then it will return a struct with all of the units save for nsecs (since nsecs would always be 0 when hnsecs is one of the units as Duration has hnsec precision).

       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       auto result = d.split();
       assert(result.weeks == 5);
       assert(result.days == 4);
       assert(result.hours == 17);
       assert(result.minutes == 0);
       assert(result.seconds == 2);
       assert(result.msecs == 1);
       assert(result.usecs == 200);
       assert(result.hnsecs == 7);

   Calling Duration.get or its wrappers for each of the units would be equivalent to that example, only less efficient when more than one unit is requested, as the calculations would have to be done more than once. The exception is Duration.fracSec which would have given the total of the fractional seconds as the requested units rather than splitting them out.

       // Equivalent to previous example
       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       assert(d.weeks == 5);
       assert(d.days == 4);
       assert(d.hours == 17);
       assert(d.minutes == 0);
       assert(d.seconds == 2);
       assert(d.fracSec.msecs == 1);
       assert(d.fracSec.usecs == 1200);
       assert(d.fracSec.hnsecs == 12_007);

   It is hoped that Duration.split will be less confusing and thus result in fewer bugs, but it's definitely the case that it's more powerful. It's also a great example of D's metaprogramming capabilities given how it splits out only the requested units and even is able to return a struct with fields with the same names as the requested units. This on top of being able to handle a variety of integral types as arguments. And its implemenation isn't even very complicated.
2. Some built-in type properties have been replaced with library functions:

   Built-in array properties dup and idup were replaced with (module-scoped) free functions in the object module, thanks to D's support of Uniform Function Call Syntax.

   Built-in associative array properties rehash, dup, byKey, byValue, keys, values, and get were also replaced with free functions in the object module.

3. Associative array keys now require equality rather than ordering:

   Until 2.065, opCmp was used to customize the comparison of AA struct keys.

       void main()
       {
           int[MyKey] aa;
       }

       struct MyKey
       {
           int x;
           int y;  // want to be ignored for AA key comparison

           int opCmp(ref const MyKey rhs) const
           {
               if (this.x == rhs.x)
                   return 0;

               // defined order was merely unused for AA keys.
               return this.x > rhs.x ? 1 : -1;
           }
       }

   From 2.066, the AA implementation has been changed to use the equality operator (==) for the key comparison. So the MyKey struct should be modified to:

       struct MyKey
       {
           int x;
           int y;  // want to be ignored for AA key comparison

           int opEquals(ref const MyKey rhs) const
           {
               return this.x == rhs.x;
           }
       }

Version D 2.065.0 February 24, 2014

#### Compiler Changes

1. Extensionless D source file names can now be run when using the -run switch.

#### Language Changes

1. Goto jumps now cannot skip variable declarations.
2. All instantiated functions now infer their attributes.
3. Add a new type qualifier inout const.
4. Entire slicing operation of built-in tuple is now accepted.
5. Packages and module names now have no type.
6. Const and immutable fields with initializers are now deprecated.
7. Deprecate unordered floating point comparisons.
8. Deprecate .min property for floating-point types.
9. CTFE can handle overlapped union fields.
10. Add a new trait getAliasThis.
11. Mixing struct constructors and static opCall is no longer allowed.

#### Library Changes

1. Many functions in std.algorithm can now be used as predicates to other functions.
2. Allow std.algorithm.all to be used without a predicate.
3. Add std.uni.byGrapheme and std.uni.byCodePoint.
4. Add support for any number of arguments to std.range.only.

#### Linker Changes

1. Added /LARGEADDRESSAWARE to the Win32 Optlink linker.

List of all bug fixes and enhancements in D 2.065.

#### Compiler Changes

1. Extensionless D source file names can now be run when using the -run switch:

   On Posix systems it is frequently useful to have a shebang line at the start of an extensionless file, which marks the tool used to compile the script. It's now possible to use this technique with D, e.g. the following is a D source file with the file name "my-script":

       #!rdmd

       void main()
       {
       }

   Note: This does not allow an arbitrary extension, as D source files need to be proper D identifiers.

   Note: This feature is not available on Windows, as Windows does not have extensionless executable files.

   Note: When compiling, and in order to avoid the default behavior of generating an extensionless executable which would overwrite the source file, the compiler will generate "a.out" instead.

#### Language Changes

1. Goto jumps now cannot skip variable declarations:

   For a very long period, the following code had been allowed by mistake, but it is prohibited now:

       import std.stdio;

       void main()
       {
           goto Label; // Error: goto skips declaration of variable v

           int v = 42;

       Label:
           writeln(v);
       }

2. All instantiated functions now infer their attributes:

   Regardless of how directly or indirectly a function is instantiated, its attributes will still be inferred:

       struct S(T)
       {
           T square(T x)
           {
               T calc()
               {
                   return x * x;
               }
               return calc();
           }

           static double pi() { return 3.141592; }
       }

       void main() pure @safe nothrow
       {
           S!int s;

           // S!int.square and its nested function calc are instantiated functions, so
           // their attributes are inferred as pure and callable from main()
           assert(s.square(2) == 4);  // ok

           // static member function attributes are also inferred now
           auto pi = typeof(s).pi();
       }

3. Add a new type qualifier inout const:

   Until now, the common type of immutable(T) and inout(T) had been const(T). But that loses the inout information, which might then refuse some valid code. Now the type becomes inout(const(T)), which meaningfully propagates the appropriate type qualifier.

       inout(const(int))[] foo(bool condition, inout(int)[] x, immutable(int)[] y)
       {
           static assert(is(typeof(condition ? x : y) == inout(const(int))[]));
           return condition ? x : y;
       }

       void main()
       {
           int[] marr = [1,2,3];
           const(int)[] carr = [4,5,6];
           immutable(int)[] iarr = [7,8,9];

           // inout(const(int))[] can go back to const(int)[] or immutable(int)[].
           static assert(is(typeof(foo(true, marr, iarr)) == const(int)[]));
           static assert(is(typeof(foo(true, carr, iarr)) == const(int)[]));
           static assert(is(typeof(foo(true, iarr, iarr)) == immutable(int)[]));
       }

4. Entire slicing operation of built-in tuple is now accepted:

   Bugzilla 8244: cannot slice a type tuple with '[]' in locations where a type is valid:

       import std.typetuple;
       alias Types = TypeTuple!(int, double, string);

       // Was error in 2.064, but allowed from 2.065.
       alias Types2 = Types[];
       static assert(is(Types == Types2));

5. Packages and module names now have no type:

   Bugzilla 9081: Modules shouldn't have a type

       import std.stdio;

       // Both had printed 'void' in 2.064.
       // From 2.065, both will cause "has no type" error.
       pragma(msg, typeof(std));
       pragma(msg, typeof(std.stdio));

   By the change, an idiom that used to work is(typeof(package_or_module_name)) is changed to not work. Instead use: __traits(compiles, package_or_module_name).

6. Const and immutable fields with initializers are now deprecated:

   Eventually, they will be changed to occupy space in the object. Such fields should now be changed to enum or static. See also the release note in 2.063.

   Related to that, void-initialized const or immutable fields will now occupy space in the object instance ahead of schedule:

       struct S
       {
           const int[1000] x = void;

           this(int n)
           {
               // Was disallowed in 2.064.
               // From 2.065 x is a field of runtime object.
               x[] = n;
           }
       }

       // S.sizeof had been 1 in 2.064.
       // From 2.065, field s.x occupies space in the object.
       static assert(S.sizeof == int.sizeof * 1000);

       void main()
       {
           S s = S(3);

           foreach (e; s.x)
           {
               assert(e == 3); // OK
           }
       }

7. Deprecate unordered floating point comparisons:

   Bugzilla 10369: Deprecate unordered floating point comparisons

8. Deprecate .min property for floating-point types:

   Bugzilla 10439: Deprecate float.min, double.min, real.min

9. CTFE can handle overlapped union fields:

   Example code:

       union U
       {
           size_t x;
           int* y;
       }

       bool test()
       {
           U u;
           assert(u.x == 0);
           // In here, reading u.y will cause CTFE error.

           u.y = [1,2,3].ptr;
           // Writing value to overlapped field u.y will make corresponding field u.x invalid.

           assert(u.y[0..3] == [1,2,3]);
           // u.y holds valid field and reading it is allowed
           // In here, reading u.x will cause CTFE error.

           u.x = 10;
           // Set value to u.x again.
           assert(u.x == 10);  // OK
           // In here, reading u.y will cause CTFE error.

           return true;
       }
       static assert(test());  // run CTFE

   Bit image reinterpretation by using two overlapped union fields is not allowed during CTFE.

10. Add a new trait getAliasThis:

    The new getAliasThis trait will return a tuple of field names which are marked as the subtypes of an aggregate type. For example:

        struct S
        {
            string var;
            alias var this;
        }

        static assert(__traits(getAliasThis, S)[0] == "var");

    Note: Multiple subtyping is not yet implemented in D, therefore this trait will always return a tuple of length 1.

11. Mixing struct constructors and static opCall is no longer allowed:

    This was not implemented correctly and caused ambiguities.

    Example:

        struct S
        {
            this(int i) {}

            static S opCall()   // disallowed due to constructor
            {
                return S.init;
            }
        }

    Note: static opCall can be used to simulate struct constructors with no arguments, but this is not recommended practice. Instead, the preferred solution is to use a factory function to create struct instances.

#### Library Changes

1. Many functions in std.algorithm can now be used as predicates to other functions:

   Functions such as any, all, canFind and equal are now templates, which allows them to be used as predicates to other templates, as well as allowing the user to alias an instantiation of any such templates. For an example of how this allows terser syntax in user-code, in the following example the programmer wants to check whether all the strings in a string array have at least one ASCII digit:

       import std.algorithm : all;
       import std.ascii : isDigit;

       void main()
       {
           string[] inputs = ["foo1", "bar2"];

           bool allContainDigit;
           foreach (input; inputs)
           {
               if (!any!isDigit(input))  // none of the characters are ASCII digits
               {
                   allContainDigit = false;
                   break;
               }
           }
       }

   But it is now simpler to use the any template itself as a predicate. We can make it a predicate to another useful template, the all template:

       import std.algorithm : any, all;
       import std.ascii : isDigit;

       void main()
       {
           string[] inputs = ["foo1", "bar2"];
           bool allContainDigit = all!(any!isDigit)(inputs);
       }

   In addition to allowing these functions to become predicates they can now also be aliased, which allow you to make your functions simpler to understand:

       import std.algorithm : any, all;
       import std.ascii : isDigit;

       void main()
       {
           alias isAnyDigit = any!isDigit;  // less visual noise and a self-describing function

           string[] inputs = ["foo1", "bar2"];
           bool allContainDigit = all!isAnyDigit(inputs);  // easier to understand

           alias doAllContainDigits = all!isAnyDigit;  // or wrap the entire algorithm into one symbol!

           assert( doAllContainDigits(["1", "a 1", "b 2"]));  // self-describing code
           assert(!doAllContainDigits(["c", "a 1", "b 2"]));
       }

   You can of course combine all and any in a number of combinations. For example, if you want to reverse the test and instead check whether any of the strings in the string array contain all digits, the code might look like the following:

       import std.algorithm : any, all;
       import std.ascii : isDigit;

       void main()
       {
           alias areAllDigits = all!isDigit;

           alias areAnyIntegrals = any!areAllDigits;

           assert( areAnyIntegrals(["123", "456"]));
           assert( areAnyIntegrals(["abc", "123"]));  // "123" is a number
           assert(!areAnyIntegrals(["abc", "def123"])); // "def123" is not really a number
       }

   If on the other hand you want to ensure that all strings in the string array contain all digits, the could might look like the following:

       import std.algorithm : any, all;
       import std.ascii : isDigit;

       void main()
       {
           alias areAllDigits = all!isDigit;

           alias allStringsDigits = all!areAllDigits;

           assert( allStringsDigits(["123", "456"]));
           assert(!allStringsDigits(["abc", "123"]));  // "123" is a number, but "abc" is not
       }

2. Allow std.algorithm.all to be used without a predicate.

   You no longer need to pass a predicate if you want to match all items in a range which implicitly convert to true:

       import std.algorithm;

       void main()
       {
           auto arr1 = [true, true, true];
           assert( all(arr1));  // all values are true

           auto arr2 = [false, true, true];
           assert(!all(arr2));  // all values are not true

           auto arr3 = [1, 2, 3];
           assert( all(arr3));  // all values convert to true

           auto arr4 = [0, 2, 3];
           assert(!all(arr4));  // all values do not convert to true
       }

3. Add std.uni.byGrapheme and std.uni.byCodePoint.

   Complementary higher-order ranges which enable range operations on graphemes:

       import std.array : array;
       import std.range : retro;
       import std.string : text;
       import std.uni : byCodePoint, byGrapheme;

       void main()
       {
           string s = "noe\u0308l"; // noël
           // reverse it and convert the result back to UTF-8
           string reverse = s.byGrapheme()
               .array() // Note: byGrapheme will support bidirectionality in the future
               .retro()
               .byCodePoint()
               .text();

           assert(reverse == "le\u0308on"); // lëon
       }

   Note that byGrapheme will support bidirectionality in the future, obviating the need for array in the above example.
4. Add support for any number of arguments to std.range.only.

   only can now be used with more than one argument:

       import std.algorithm : joiner;
       import std.range : equal, only;

       void main()
       {
           assert(only("one", "two", "three").joiner(" ").equal("one two three"));
       }

   Additionally, only() is now a way to get an empty range.

#### Linker Changes

1. Added /LARGEADDRESSAWARE to the Win32 Optlink linker.

   When using the default Optlink linker on win32 (for linking 32-bit object files and executables), the /LARGEADDRESSAWARE option tells the linker that the application can handle addresses larger than 2 gigabytes. This is equivalent to Visual C's linker option of the same name since this is an operating-system feature that is enabled by setting a specific flag in the executable.

List of all bug fixes and enhancements in D 2.064.

#### Language Enhancements

1. Introduced the ability to define and import package modules.

   The new package import feature allows you to define a library module which has the purpose of publicly importing any other modules in that library. The user can then simply import this one module and use the library as if the user import all the modules at once. For example:

   libweb/client.d:

       module libweb.client;

       void runClient() { }

   libweb/server.d:

       module libweb.server;

       void runServer() { }

   libweb/package.d:

       module libweb;

       public import libweb.client;
       public import libweb.server;

   Notice that the package module must always have the file name package.d. The module name is the qualified name of the package. The user then uses the standard import syntax to import a package module, simply using the module declaration name to import the package:

   test.d:

       module test;

       import libweb;

       void main()
       {
           startServer();
           startClient();
       }

   The following is an example of a package module of a sub-package:

   libweb/utils/package.d:

       module libweb.utils;  // fully qualified name of the package, not just "utils"!

       // publicly import modules from within the 'libweb.utils' package.
       public import libweb.utils.conv;
       public import libweb.utils.text;

   To import this subpackage, use the standard module import declaration:

   test.d:

       module test;

       import libweb.utils;

       void main()
       {
       }

   ### Rationale:

   Until now public import modules were implementable, but only by convention. The user would typically have to import a specific module specified by the library author, e.g. libweb.all or libweb._. Introducing the package import feature standardizes this common convention of library authors

2. Introduced a new eponymous template syntax.

   The new eponymous template syntax allows you to write shorter templates without having to explicitly define and repeat the template name when using traditional eponymous templates. For example, before 2.064 eponymous templates were written and used like the following:

       template Tuple(T...) { alias Tuple = T; }

       template isIntOrFloat(T)
       {
           static if (is(T == int) || is(T == float))
               enum isIntOrFloat = true;
           else
               enum isIntOrFloat = false;
       }

       void main()
       {
           alias Tup = Tuple!(int, float, string);
           static assert(isIntOrFloat!(Tup[0]));  // int is an int or a float
           static assert(isIntOrFloat!(Tup[1]));  // float is an int or a float
           static assert(!isIntOrFloat!(Tup[2])); // string is neither an int nor a float
       }

   With the new eponymous syntax, the implementation code becomes much simpler:

       alias Tuple(T...) = T;

       enum isIntOrFloat(T) = is(T == int) || is(T == float);

       void main()
       {
           alias Tup = Tuple!(int, float, string);
           static assert(isIntOrFloat!(Tup[0]));  // int is an int or a float
           static assert(isIntOrFloat!(Tup[1]));  // float is an int or a float
           static assert(!isIntOrFloat!(Tup[2])); // string is neither an int nor a float
       }

   Notice how you need to start the declaration of such a template with an alias or enum, rather than starting it with the keyword template.

   ### Limitations:

   Currently you cannot define template constraints for these types of templates. This limitation may be lifted in a future release.

3. Postfix expressions are now allowed after a new expression.

   Before 2.064, you could not both instantiate a new class and call a method or access a property of the object without having to wrap the new expression in parentheses:

       class Server
       {
           this(string[] args) { }
           void run() { }
       }

       void main(string[] args)
       {
           (new Server(args)).run();
       }

   In 2.064 this limitation has been lifted, allowing you to write the code as follows:

       class Server
       {
           this(string[] args) { }
           void run() { }
       }

       void main(string[] args)
       {
           new Server(args).run();
       }

   Note: When instantiating a class with the default constructor, you must insert an empty set of parentheses before accessing a field or calling a method on the object:

       class Server
       {
           this() { }
           void run() { }
       }

       void main()
       {
           new Server.run();    // error
           new Server().run();  // ok
       }

4. Implicit Function Template Instantiation now supports enclosing type/scope deduction:

IFTI has been improved, allowing you to write code such as the following:

    struct A
    {
        struct Foo { }
    }

    struct B
    {
        struct Foo { }
    }

    /**
    Templated function which expects the second argument to be of type 'Foo,
    which is a nested in the type 'T'.
    */
    void call(T)(T t, T.Foo foo) { }

    void main()
    {
        auto a = A();
        auto a_f = A.Foo();
        call(a, a_f);  // ok

        auto b = B();
        auto b_f = B.Foo();
        call(b, b_f);  // ok

        call(a, b_f);  // fails: b_f is typed as B.Foo, not A.Foo
    }

This IFTI feature also allows you to retrieve the module of a symbol, by using an alias template parameter, rather than a type one:

    module my_module;

    struct A
    {
        struct B { }
    }

    void foo(alias Mod)(Mod.A, Mod.A.B)
    {
        // 'Mod' is deduced to be the module 'my_module' which encloses the struct 'A'
        static assert(__traits(isSame, Mod, my_module));
    }

    void main()
    {
        A a;
        A.B b;
        foo(a, b);  // ok
    }

5. DDoc can now warn the user when the symbol names in a ddoc comment do not match the actual code:

Here is an example documented function, where the parameter names are wrongly documented:

    /**
        This is the sum function.

        params:
            x = The first parameter
            y = The second parameter
    */
    int sum(int a, int b)
    {
        return a + b;
    }

Generating the documentation with warnings enabled will emit the following:

    dmd -D -c -w test.d

    test.d(8): Warning: Ddoc: function declaration has no parameter 'x'
    test.d(8): Warning: Ddoc: function declaration has no parameter 'y'

This feature can help ensure that the documentation for library code is always kept up-to-date.

Note: Remember to use the -w switch when building the documentation with the -D switch in order to enable these warnings.

6. Strings literals which are sliced are now implicitly convertible to a char pointer:

To help ease interacting with C libraries which expect strings as null-terminated pointers, slicing string literals (not variables!) will now allow the implicit conversion to such a pointer:

    extern(C) void call(const(char)* str) { }

    void main()
    {
        const(char)* abc = "abc";
        call(abc);  // already previously allowed

        const(char)* ab = "abc"[0 .. 2];
        call(ab);   // allowed in 2.064
    }

7. Templated and non-template functions can now be overloaded against each other:

    auto foo(int n) { return 1; }
    auto foo(T)(T t) { return 2; }

    void main()
    {
        assert(foo(100) == 1);
        assert(foo("a") == 2);

        // Integer literal 10L can be converted to int without loss of precisions.
        // Then the call matches to foo(int n).
        assert(foo(10L) == 1);

        // A runtime variable 'num' typed long is not implicitly convertible to int.
        // Then the call matches to foo(T)(T t).
        long num = 10L;
        assert(foo(num) == 2);
    }

8. Cross-module template declarations can now make an overload set:

Template declarations are now overloadable just like regular function declarations. Templates with matching names from multiple modules will introduce an overload set:

    module a;

    template Traits(T) if (is(T == double))
    {
        enum Traits = "abc";
    }

    auto func(T, A...)(A args) if (is(T == double))
    {
        return 1;
    }

    module b;

    template Traits(T) if (is(T == string))
    {
        enum Traits = "def";
    }

    auto func(T, A...)(A args) if (is(T == string))
    {
        return 2;
    }

    module c;
    import a, b;
    static assert(Traits!double == "abc");  // matches to a.Traits
    static assert(Traits!string == "def");  // matches to b.Traits
    void main()
    {
        assert(func!double(1, "msg") == 1);  // matches to a.func(T, A...)
        assert(func!string(1, "msg") == 2);  // matches to b.func(T, A...)
    }

### Limitations:

Merging template overload sets by using an alias declaration is currently not supported. The limitation will be lifted in a future release.

#### Compiler Changes

1. Allow printing dependencies to stdout for tooling support:

You can now use the -deps switch without having to specify a filename. The dependencies will then be printed to standard output, allowing both users and tools to introspect the dependencies in the output.

The types of dependencies which are printed out are as follows:

depsImport: Module imports found (same as -deps=file output, except prefixed with depsImport)

depsVersion: Versions (except standard ones and ones set in the module itself)

depsFile: String imports found, e.g. string x = import("foo.txt");

depsLib: Libraries specified with a pragma(lib) statement

depsDebug: Any debug() statements found (except the ones set in the module itself)

#### Compiler Enhancements

1. Introduced the getUnitTests trait for retrieval and custom execution of unittests:

With the new getUnitTests trait you can retrieve all unittest in a module or an aggregate, and then run the tests manually. Here's an example of implementing a custom unittest running routine which prints out some additional statistics:

    import core.runtime;
    import core.exception;
    import std.stdio;

    shared static this()
    {
        // this overrides the default D runtime unittest runner function,
        // since we're providing a __traits-based one in our main function.
        Runtime.moduleUnitTester = { return true; };
    }

    unittest
    {
        assert(1);  // passes.
    }

    unittest
    {
        assert(0);  // fails.
    }

    unittest
    {
        assert(1);  // passes.
    }

    void main()
    {
        Throwable[] errors;  // collect all thrown exceptions.
        size_t passCount;    // count the number of unittests which pass.

        // iterate over each unittest (this is a tuple).
        foreach (test; __traits(getUnitTests, my_module))
        {
            try
            {
                test();
                passCount++;
            }
            catch (Throwable error)
            {
                errors ~= error;
            }
        }

        // print out the errors or the statistics.
        if (errors.length)
        {
            writeln("Some unittests failed:\n");
            foreach (error; errors)
                writeln(error);
        }
        else
        {
            writefln("All unittests passed. Passed unittest count: %s", passCount);
        }
    }

Note: You must compile with the -unittest flag to be able to retrieve the unittests.

Note: By default the D runtime provides its own unittest execution function. If you want to avoid it from being invoked at runtime (before the main function is called) you need to set a custom one by assigning to Runtime.moduleUnitTester in the module constructor. The one used in the above test-case simply returns true, which allows the main function to be called.

Note: The getUnitTests trait is not recursive. This means that calling it on a module will not retrieve unittests which are nested in aggregates in that module.

2. Introduced the getVirtualIndex trait to get the index of a virtual function:

You can use this trait to get the index of a virtual method in the virtual method table:

    class C
    {
        void foo() { }
        void bar() { }
    }

    class D : C
    {
        void doo() { }
        void doo(int) { }
        void doo(double) { }
    }

    void main()
    {
        /**
            Note that each class implicitly inherits from the Object class,
            so the following will most likely not begin with index 0.
        */
        pragma(msg, __traits(getVirtualIndex, D.foo));
        pragma(msg, __traits(getVirtualIndex, D.bar));

        /**
            When dealing with overloads you can use the getOverloads trait to index
            into a specific method
        */
        pragma(msg, __traits(getVirtualIndex, __traits(getOverloads, D, "doo")[0]));
        pragma(msg, __traits(getVirtualIndex, __traits(getOverloads, D, "doo")[1]));
        pragma(msg, __traits(getVirtualIndex, __traits(getOverloads, D, "doo")[2]));
    }

3. Introduced the isOverrideFunction trait which indicates whether or not a function is overriding:

    class Base
    {
        void foo() { }
    }

    class Foo : Base
    {
        override void foo() { }
        void bar() { }
    }

    static assert (__traits(isOverrideFunction, Base.foo) == false);
    static assert (__traits(isOverrideFunction, Foo.foo)  == true);
    static assert (__traits(isOverrideFunction, Foo.bar)  == false);

#### Phobos enhancements

1. Introduced the structural typesafe conversion functions wrap and unwrap:

Sometimes you may want your class to be usable with a function which expects a specific interface argument type, but you do not necessarily want to edit the class to inherit that interface. The class could also be implemented in another library for which you do not have the source code, which means you wouldn't be able to edit the inheritance list of that class.

The new wrap function allows you to perform a structural cast, allowing a class object to act as if it were an object of another type. For example (note: for now please pass the -allinst flag to dmd when compiling):

    import std.typecons;

    interface IDrawable
    {
        void drawLine(int x1, int y1, int x2, int y2);
    }

    class ImageDraw  // note: it does not inherit IDrawable.
    {
        void drawLine(int x1, int y1, int x2, int y2) { }
    }

    /** Draw a rectangle outline. */
    void drawRect(IDrawable draw)
    {
        draw.drawLine(  0,   0, 100,   0);
        draw.drawLine(100,   0, 100, 100);
        draw.drawLine(  0, 100, 100, 100);
        draw.drawLine(  0,   0,   0, 100);
    }

    void main()
    {
        auto imageDraw = new ImageDraw();
        drawRect(imageDraw);  // error: can't call this, ImageDraw is not an IDrawable.

        // perform a structural cast.
        IDrawable i = wrap!IDrawable(imageDraw);
        drawRect(i);  // and now imageDraw can act as an IDrawable.
    }

The wrap function can also be used with classes which define an opDispatch function, for example:

    import std.typecons;

    interface IDrawable
    {
        void drawLine(int x1, int y1, int x2, int y2);
        void drawRect(int x, int y, int width, int height);
    }

    class ImageDraw
    {
        void opDispatch(string name, Args...)(Args args)
            if (name == "drawLine")
        {
            // ...
        }

        void opDispatch(string name, Args...)(Args args)
            if (name == "drawRect")
        {
            // ...
        }
    }

    /** Draw some shapes. */
    void drawShapes(IDrawable draw)
    {
        draw.drawLine(0, 100, 100, 0);
        draw.drawRect(0, 0, 100, 100);
    }

    void main()
    {
        auto imageDraw = new ImageDraw();
        IDrawable i = wrap!IDrawable(imageDraw);
        drawShapes(i);
    }

You can unwrap a structurally cast object back to its original type:

    interface IDrawable
    {
        void drawLine(int x1, int y1, int x2, int y2);
    }

    class ImageDraw
    {
        void drawLine(int x1, int y1, int x2, int y2) { }
    }

    void main()
    {
        auto imageDraw = new ImageDraw();

        // perform a structural cast (note the simple UFCS syntax).
        IDrawable i = imageDraw.wrap!IDrawable;

        // get back the original type (ditto, using UFCS syntax).
        ImageDraw draw = i.unwrap!ImageDraw;
    }

And you can structurally cast to multiple interface types:

    import std.typecons;

    unittest
    {
        interface IStoppable { void stop(); }
        interface IRunnable { void run(); }

        class Timer
        {
            void run() { }
            void stop() { }
        }

        auto timer = new Timer();
        auto obj = timer.wrap!(IStoppable, IRunnable);

        // extract the individual structurally casted types
        // from the wrapped type
        IStoppable iStop = obj;
        IRunnable  iRun  = obj;

        iRun.run();
        iStop.stop();
    }

2. std.conv.to and std.string.format are now pure functions:

Since 2.064, pure functions can take advantage of to and format. For example:

    import std.conv;
    import std.string;

    void main() pure  // this main is a pure function.
    {
        string date = format("%s.%s.%s", 2013, 12, 10);
        int one = to!int(1.0);
    }

3. Introduced generic strip/stripLeft/stripRight functions:

The new generic strip functions allow you to not only strip strings but also any other Input range (stripLeft) or Bidirectional range (strip/stripRight), for example:

    import std.algorithm;

    void main()
    {
        // strip whitespace.
        assert("  foobar  ".strip!(a => a == ' ')() == "foobar");

        // an audio waveform.
        float[] data = [0.0, 0.0, 0.1, 0.5, 0.2];

        // strip leading silence in the waveform.
        assert(data.strip!(a => a < 0.1)().length == 3);
    }

4. Introduced an overload of std.string.translate which can take a buffer, avoiding the need for implicit memory allocations:

To avoid implicit memory allocations translate now features overloads which can take an output range to write the contents to. For example:

    import std.array;
    import std.string;

    void main()
    {
        dchar[dchar] transTable = ['a' : '1', 'b' : '2', 'c': '3'];

        // create our output range by using the Phobos Appender.
        auto buffer = appender!(dchar[])();

        auto toRemove = null;  // don't remove any characters.

        translate("abcdef", transTable, toRemove, buffer);
        assert(buffer.data == "123def");

        // or use a static array to avoid heap allocations.
        // note: if the buffer is too small an exception will be thrown.
        dchar[6] dbuffer;
        translate("abcdef", transTable, toRemove, dbuffer[]);
        assert(dbuffer == "123def");
    }

5. Introduced the thisExePath function to retrieve the executable path of the currently running process:

With the thisExePath function you can retrieve the current executable path:

    import std.file;
    import std.stdio;

    void main(string[] args)
    {
        // Prints the full path of the current running executable.
        // Note: this may, or may not be the same as args[0]. The content
        // of args[0] is dependent of how the application was invoked, thisExePath()
        // is not. It's also possible to access thisExePath() from other parts of the
        // code than main.
        writeln(thisExePath());
    }

6. New API for std.regex match/replace functions:

The old API based around "g"(=global) flag was confusing and error prone. Moreover in some cases it was already being overriden by a function as is the case with std.regex.splitter.

New version ties the operation to the function in question, thus being simpler to understand without extra context. For the moment the "g" flag is kept working as is but the new API always overrides it where applicable. Another addition in the new API is an overload for the replace family of functions to work directly with output ranges.

To understand the difference in the API compare 2 samples below.

Before 2.064:

    void main()
    {
        import std.regex, std.algorithm, std.range, std.stdio, std.string;
        auto m = "3.141592".match(`(\d+)\.(\d+)`);
        // m is a range of ranges
        assert(m.front.equal(["3.141592", "3", "141592"]));

        // global vs non-global
        auto word = regex(`(\w)\w*`);
        auto gword = regex(`(\w)\w*`, "g");
        auto list = "tomatoes, potatoes, pineapple";
        // this will print only 'tomatoes', which raised many questions
        foreach(item; list.match(word))
            writeln(item.hit);

        // while this will print each of them
        foreach(item; list.match(gword))
            writeln(item.hit);

        auto justFirst = replace!(m => toUpper(m[1]) ~ m[0].drop(1))(list, word);
        assert(justFirst == "Tomatoes, potatoes, pineapple");
        auto allOfThem = replace!(m => toUpper(m[1]) ~ m[0].drop(1))(list, gword);
        assert(allOfThem == "Tomatoes, Potatoes, Pineapple");
    }

After 2.064:

    void main()
    {
        import std.regex, std.algorithm, std.range, std.stdio, std.string;
        auto m = "3.141592".matchFirst(`(\d+)\.(\d+)`);
        // m is simply a range of submatches
        assert(m.equal(["3.141592", "3", "141592"]));

        auto word = regex(`(\w)\w*`);
        auto list = "tomatoes, potatoes, pineapple";
        // iterates over submatches so it will print 2 lines:
        // tomatoes
        // t
        foreach(item; list.matchFirst(word))
            writeln(item);
        // so just to get the whole match:
        assert(list.matchFirst(word).hit == "tomatoes");

        // now there is no need to check if it has "g" option
        // it's crystal clear in the function name
        foreach(item; list.matchAll(word))
            writeln(item.hit);

        auto justFirst = replaceFirst!(m => toUpper(m[1]) ~ m[0].drop(1))(list, word);
        assert(justFirst == "Tomatoes, potatoes, pineapple");
        auto allOfThem = replaceAll!(m => toUpper(m[1]) ~ m[0].drop(1))(list, word);
        assert(allOfThem == "Tomatoes, Potatoes, Pineapple");

        // NEW feature - if there is no need to allocate, the resulting string
        // replacement may be just sent directly to the wire (an OutputRange)
        auto sink = stdout.lockingTextWriter();
        replaceAllInto!(m => toUpper(m[1]) ~ m[0].drop(1))(sink, list, word);
    }

The old API still works, even though eventual deprecation is planned. Also note the new functionality in form of *Into functions that forward the replacement directly to an output range avoiding extra pressure on the heap.

7. Compile-time std.regex.ctRegex now supports lookaround just like run-time one:

Now ctRegex supports full syntax spectrum of run-time one except for set algebra inside of a character class. For instance, the following now compiles and passes:

    void main()
    {
        import std.regex;
        // a word, but not a title-cased ASCII
        // ?<! inside of () means "negative lookbehind"
        auto pat = ctRegex!`\w+(?<![A-Z][a-z]*)`;
        assert(!"Hello".match(pat));
        assert("good_bay".match(pat));
    }

List of all bug fixes and enhancements in D 2.063.

#### Language Changes

1. Const and immutable fields with initializers are now warned about:

   Eventually, they will be deprecated, and then will trigger an error. Such fields should now be changed to enum or static.

   In a future release, a new behavior for them will be enabled:

   Fields in an aggregate which are not static will always be addressable. This means they will occupy space in the object:

       struct S
       {
           // used to be implicitly static in 2.062, now warns. In a future release it will become non-static.
           immutable int[] arr = [1, 2];

           // ditto
           const int[] arr2 = [1, 2];
       }

   This means that code which accessed such declarations without the this reference will no longer compile. Additionally code which depended on the size of a structure with such fields will have to be fixed:

       struct S
       {
           immutable int[] arr = [1, 2];
       }

       void main()
       {
           auto x = S.arr;  // becomes an error in a future release, 'arr' will require the 'this' reference.

           // S is size 1 in 2.062 and 2.063. In a future release this will change and the following static assert will pass.
           static assert(S.sizeof == size_t.sizeof + size_t.sizeof);  // ptr + length for the array
       }

   To make the field static again, simply use the static keyword. Alternatively make the field an enum to turn it into a manifest constant:

       struct S
       {
           static immutable int[] arr = [1, 2];
           enum arr2 = [1, 2];
       }

   Note however that manifest constants which are arrays are allocated on each usage, so you may prefer using static instead.

   ### Rationale:

   Making a field implicitly static based on whether it is const/immutable and has an initializer leads to confusion. The static keyword can be used to explicitly make any field static.

2. Constructor qualifiers are taken into account when constructing objects:

   A qualified constructor is now invoked when a const/immutable/shared aggregate object is instantiated, respectively:

       import std.stdio;

       class C
       {
           this()           { writeln("1"); }
           this() const     { writeln("2"); }
           this() immutable { writeln("3"); }
           this() shared    { writeln("4"); }
       }

       void main()
       {
           auto a = new C;           // writes "1"
           auto b = new const C;     // writes "2"
           auto c = new immutable C; // writes "3"
           auto d = new shared C;    // writes "4"
       }

   This has the consequence that aggregates which have only immutable or shared constructors can no longer be used to instantiate mutable objects:

       class C
       {
           this() immutable { }
           this() shared { }
       }

       void main()
       {
           auto c1 = new C;           // disallowed
           auto c2 = new immutable C; // ok
           auto c3 = new shared C;    // ok
       }

   On the other hand, aggregates which do not have shared or immutable constructors can no longer be used to construct shared or immutable objects, respectively:

       class C
       {
           this() { }
       }

       void main()
       {
           auto c1 = new C;           // ok
           auto c2 = new immutable C; // disallowed
           auto c3 = new shared C;    // disallowed
       }

   However, if an aggregate has a pure constructor it can be used to construct an object with any type constructor:

       class C
       {
           this() pure { }
       }

       void main()
       {
           auto c1 = new C;  // ok
           auto c2 = new immutable C;  // ok
           auto c3 = new shared C;  // ok
       }

3. Struct members which require non-bitwise comparison are now properly compared.

   In earlier releases some struct members such as arrays would be bitwise-compared in a comparison operation. This has now been changed to be a structural comparison instead:

       struct S
       {
           char[] data;
       }

       void main ()
       {
           auto s1 = S("foo".dup);
           auto s2 = S("foo".dup);

           assert(s1.data !is s2.data);  // both are unique data

           assert(s1 == s2);   // passes in 2.063
           assert(s1.data == s2.data);  // equivalent of above
       }

   If an opEquals function is not present the compiler rewrites the expression s1 == s2 to s1.tupleof == s2.tupleof. Comparing .tupleof expressions is also a feature new to D in the 2.063 release.

4. Array copy operations now always require using the slice syntax:

   The right-hand-side of an array copy operation now requires using the slice syntax:

       void main()
       {
           int[][2] x;
           int[] y;
           int[] z;

           x[] = z;    // copies z (pointer + length) 2 times to x
           y[] = z;    // copies each element of z into y (compiler emits warning)
       }

   If the user intended to write such code they must use the slice syntax for both the source and target arrays:

       void main()
       {
           int[][2] x;
           int[] y;
           int[] z;

           y[] = z[];  // copies each element of z into y (no warnings)
       }

   ### Rationale:

   The compiler will emit a warning to make the user aware that the copy operation is arbitrarily expensive.

5. Types no longer act as arguments in typeof expressions:

   A type can no longer be passed to a function as a value of that type:

       T[] foo(T)(T t)
       {
           return null;
       }

       void main()
       {
           alias int Int;

           // used to work (only with an alias), now a compiler error
           alias typeof(foo(Int)) IntArray;
       }

   If the user wants to pass an argument of a certain type, they can use the .init property:

       T[] foo(T)(T t)
       {
           return null;
       }

       void main()
       {
           alias typeof(foo(int.init)) IntArray;  // ok
       }

   ### Rationale:

   Treating types as expressions in special contexts only leads to confusion. Instead, the .init property can be used for such purposes.

6. The index variable in a foreach range is no longer implicitly a reference:

   The index variable in a foreach range is now by default a value type:

       void main()
       {
           size_t count;
           foreach (n; 0 .. 10)
           {
               ++n;
               ++count;
           }
           assert(count == 10);  // passes
       }

   If the user wants to modify the index variable he must use the ref keyword:

       void main()
       {
           size_t count;
           foreach (ref n; 0 .. 10)
           {
               ++n;
               ++count;
           }
           assert(count == 5);
       }

   ### Rationale:

   Making the index variable implicitly ref can introduce bugs that are hard to track down.

7. Associative array entries are no longer default-initialized before assignment:

   An associative array entry used to be default-initialized before assignment took place:

       void main()
       {
           int[int] aa;
           aa[1] = aa[1] + 1;   // no Error thrown in 2.062
           assert(aa[1] == 1);  // worked in 2.062
       }

   In 2.063, accessing an entry which does not exist will now throw a RangeError:

       void main()
       {
           int[int] aa;
           aa[1] = aa[1] + 1;   // RangeError thrown in 2.063
       }

   ### Rationale:

   Default-initialization during assignment can be a source of bugs.

8. The const attribute is no longer inherited in overriden methods.

   Method overrides no longer inherit constness of the base method:

       class A
       {
           void foo() const { }
       }

       class B : A
       {
           // used to work in 2.062, now an error
           override void foo() { }  // note missing 'const'
       }

   If the user wants to override a const method he has to mark the overriden method as const:

       class A
       {
           void foo() const { }
       }

       class B : A
       {
           override void foo() const { }  // ok
       }

   The feature allows introducing new overloads based on the constness of the method:

       class A
       {
           void foo() const { }
       }

       class B : A
       {
           // introduces new overload (not override!)
           void foo() { }

           // if the above overload is introduced the user must either:
           // a: re-introduce the const overload to prevent function hijacking
           alias super.foo foo;  // without this you will get a compiler error

           // or b: provide a properly typed override:
           override void foo() const { }
       }

9. typeof(null) no longer implicitly converts to T[]:

   The following code used to be allowed:

       void f(int[] function() del)
       {
           assert(!del());  // fails
       }

       typeof(null) g() { return null; }

       void main()
       {
           f(&g);
           f(() => null);
       }

   However the implicit conversion would end up generating wrong code. To work around this, make sure the return type is typed properly, or use (T[]).init in the return expression of a lambda expression:

       void f(int[] function() del)
       {
           assert(!del());  // passes
       }

       int[] g() { return null; }  // fixed return type

       void main()
       {
           f(&g);  // ok
           f(() => (int[]).init);  // ok
       }

10. The Template This Parameter now changes the member function qualifier:

    The Template This Parameter can now be used to infer the qualifier of this to member functions:

        struct S
        {
            void foo(this T)()
            {
            }
        }

        void main()
        {
             immutable S s;
             s.foo();  // makes S.foo immutable
        }

11. Array slices are now r-values:

    Array slices are no longer l-values. This means an address can no longer be taken of a slice, and slices cannot be passed by ref to functions:

        void foo(ref int[] arr) { arr = new int[10]; }

        void main()
        {
            int[] arr;
            foo(arr);  // ok
            assert(arr.length == 10);

            foo(arr[]);  // disallowed in 2.063, the slice is an r-value
            auto ptr = &arr[1..2];  // disallowed in 2.063, cannot take address of r-value
        }

    To work around this you can make your function take an r-value if it doesn't need to reassign and resize the slice, but only needs to read or modify its contents. Otherwise, to accept both l-values and r-values you can make your function take its argument by auto ref:

        void take(int[] arr) { }
        void takeRef(ref int[] arr) { }
        void takeAutoRef(T)(auto ref T[] arr) { }

        void main()
        {
            int[] arr = [1, 2, 3, 4];
            take(arr);          // ok
            takeRef(arr);       // ok
            takeAutoRef(arr);   // ok

            int[] arr2 = arr[1 .. 2];
            take(arr2);         // ok, arr2 is a variable
            takeRef(arr2);      // ditto
            takeAutoRef(arr2);  // ditto

            take(arr[1 .. 2]);         // ok
            takeRef(arr[1 .. 2]);      // error, cannot pass r-value by reference
            takeAutoRef(arr[1 .. 2]);  // ok
        }

    ### Rationale:

    Passing slices by reference had no observable effect when reassigning or resizing such a slice at the call site, therefore such slices should by default be r-values. For example, the following code used to be allowed but is now a compile-time error:

        void reAssign(ref int[] arr) { arr = new int[2]; }
        void reSize(ref int[] arr)   { arr.length = 10; }

        void main()
        {
            int[] arr = [1, 2, 3, 4];

            reAssign(arr[0 .. 4]);  // reassigning has no observable effect at the call site
            assert(arr == [1, 2, 3, 4]);

            reSize(arr[0 .. 4]);    // resizing has no observable effect at the call site
            assert(arr.length == 4);
        }

12. Accessing a non-static field without a this reference is only allowed in certain contexts:

    Accessing non-static fields used to be allowed in many contexts, but is now limited to only a few:

    - offsetof, init, and other built-in properties are allowed:

        struct S { int field; }

        void main()
        {
            auto a = S.field.offsetof;  // ok, statically known
            auto c = S.field.max;       // ditto
            auto d = S.field;           // disallowed, no `this` reference
        }

    - When invoking static methods of a non-static field:

        struct Foo
        {
            static struct Bar
            {
                static int get() { return 0; }
            }

            Bar bar;
        }

        void main()
        {
            static assert(Foo.bar.get() == 0);  // ok, equivalent to `typeof(Foo.bar).get()`
        }

    - When accessing static fields implicitly using an alias this expression:

        struct Foo
        {
            static struct Bar
            {
                static int get() { return 0; }
            }

            Bar bar;
            alias bar this;
        }

        void main()
        {
            static assert(Foo.get() == 0);  // ok, equivalent to 'typeof(Foo.bar).get()'
        }

13. Arrays no longer implicitly convert to a pointer:

    The implicit conversion of an array to a pointer was a deprecated feature:

        void foo(int* p) { }

        void main()
        {
            int[] arr = [1, 2];
            foo(arr);   // ok if -d switch is used during compilation
        }

    This feature has now been completely removed. The workaround is to either use the .ptr property, or explicitly pass the pointer to the first element:

        void foo(int* p) { }

        void main()
        {
            int[] arr = [1, 2];
            foo(arr);      // compile error
            foo(arr.ptr);  // ok
            foo(&arr[0]);  // ok
        }

#### Language Enhancements

1. Expressions which return unique objects can be implicitly casted to immutable:

   Expressions such as new for objects and arrays, and dup for arrays, can now be inferred to be unique. This allows the compiler to implicitly convert such an expression to immutable:

       class C { }

       void main()
       {
           immutable int[] arr1 = new int[](3);   // ok
           immutable int[] arr2 = [1, 2, 3].dup;  // ok in 2.063
           immutable C[] arr3 = [new C, new C].dup;  // ok in 2.063
       }

2. Static array of void can now be user-initialized.

   A static array of void could not be initialized in user-code:

       void main()
       {
           void[2] varr1;  // error in 2.062
           void[2] varr2 = (void[2]).init;  // error in 2.062
           void[2] varr3 = void;  // ok in 2.062
       }

   In 2.063, an explicit initializer can be used:

       void main()
       {
           void[2] varr1;  // still an error in 2.063
           void[2] varr2 = (void[2]).init;  // ok in 2.063
           void[2] varr3 = void;  // ok in 2.063
       }

   The .init property effectively zero-initializes the array.

   ### Rationale:

   The restriction has been lifted to allow generic code to use .init without having to specialize for static void arrays.

3. Aggregates can now contain multiple invariants:

   If an aggregate type has multiple invariants, the invariants' bodies will be merged into a single invariant function and will be run in sequence. Note that the code in one invariant cannot reference code or data in another invariant:

       struct S
       {
           int x;

           void foo() { }

           invariant()
           {
               int local;
               assert(x != 0);
           }

           invariant()
           {
               // local = 1;  // invariant does not have access to the other invariant's body
               assert(x % 2 == 0);
           }
       }

       void main()
       {
           S s = S(2);
           s.foo();  // invoking public function triggers both invariants in sequence
       }

4. Methods of templated aggregates can now infer attributes:

   If a function with some attributes instantiates a templated aggregate, it's member functions will infer those attributes:

       struct S(T)
       {
           T square(T x)
           {
               return x * x;
           }
       }

       void main() pure
       {
           S!int s;  // S!int.square becomes pure and callable from main()
           assert(s.square(2) == 4);  // ok
       }

5. is expression no longer requires an identifier:

   In some cases the is expression required an identifier even when you didn't have a use for it:

       void main()
       {
           alias AA = string[int];

           static if (is(AA _ == V[K], V, K))
           {
               pragma(msg, _);  // prints string[int]
               pragma(msg, K);  // prints int
               pragma(msg, V);  // prints string
           }
       }

   The identifier is no longer required, so the above can be rewritten to:

       void main()
       {
           alias AA = string[int];

           static if (is(AA == V[K], V, K))
           {
               pragma(msg, AA); // prints string[int]
               pragma(msg, K);  // prints int
               pragma(msg, V);  // prints string
           }
       }

6. Dynamic arrays of known size can be implicitly cast to static arrays in some contexts:

   In some contexts the compiler knows the size of a dynamic array or of a slice of an array. In such a case the compiler will allow an implicit conversion to a static array of the same size:

       void foo(int[4] x) { }

       void main()
       {
           int[] arr = [1, 2, 3, 4, 5, 6, 7, 8];
           foo(arr[0 .. 4]);  // ok
       }

   Another example, where a string is converted to a reference to a static array:

       string str = "aaaabbbbccccdddd";

       void foo(ref const(char)[16] buf)
       {
           assert(buf.ptr is str.ptr);
       }

       void main()
       {
           foo(str[0..16]);  // ok
       }

   ### Limitations:

   - This feature does not yet work with complex expressions where it might be reasonable to assume the size of a slice:

       void foo(int[4] x) { }

       void main()
       {
           int[] arr = [1, 2, 3, 4, 5, 6, 7, 8];
           foreach (i; 0 .. 4)
           {
               foo(arr[i .. i + 4]);  // not yet supported
           }
       }

7. Tuples can now be void-initialized:

   You can now void-initialize a tuple variable:

       template Tuple(T...)
       {
           alias T Tuple;
       }

       void main()
       {
           Tuple!(int, int) tup1 = void;  // ok
       }

   Upon such initialization the values in the tuple are undetermined.

8. Template constraints can now be put after the inheritance list:

   Template constraints used to be allowed only before the inheritance list, leading to code where the inheritance list could be hard to spot:

       class Foo(T1, T2)
           if (is(T1 == int) && is(T2 == string)) : Base
       {
       }

   This restriction has been lifted, so you can now write:

       class Foo(T1, T2) : Base
           if (is(T1 == int) && is(T2 == string))
       {
       }

9. Tuples can now be compared for equality:

   Example:

       struct Tuple(T...) { T field; alias field this; }

       void main()
       {
           auto tup1 = Tuple!(int, int)(1, 2);
           auto tup2 = Tuple!(int, int)(1, 2);
           auto tup3 = Tuple!(int, int)(1, 3);

           assert(tup1 == tup2);  // works since 2.063
           assert(tup1 != tup3);  // works since 2.063
       }

   This also means you can now compare ParameterStorageClassTuple instances from std.traits:

       import std.traits;

       void func1(ref int x, ref int y) { }
       void func2(ref float x, ref float y) { }

       void main()
       {
           alias Storages = ParameterStorageClassTuple;
           assert(Storages!func1 == Storages!func2);
       }

   In addition to that, builtin .tupleof expressions can be used to easily compare fields of an aggregate:

       struct S
       {
           char[] a, b;

           // Implements equality test against another instance of this type.
           bool opEquals(S rhs) { return this.tupleof == rhs.tupleof; }
       }

       void main()
       {
           S s1 = S("a".dup, "b".dup);
           S s2 = S("a".dup, "b".dup);
           assert(s1 == s2);
       }

   This also allows you to implement a structural equality test against an instance of a different type:

       struct S1
       {
           char[] a, b;

           // Implements a structural equality test against any other type T
           bool opEquals(T)(T rhs) { return this.tupleof == rhs.tupleof; }
       }

       struct S2
       {
           string x, y;
       }

       void main()
       {
           auto s1 = S1("123".dup, "456".dup);
           auto s2 = S2("123", "456");
           assert(s1 == s2);
       }

   Since tuples can be sliced you can use this feature to compare a subset of tuples:

       struct S
       {
           int a, b, c, d, e;

           bool opEquals(S rhs)
           {
               // compares a, b, d, and e
               return this.tupleof[0..2] == rhs.tupleof[0..2] &&
                      this.tupleof[3..5] == rhs.tupleof[3..5];
           }
       }

       void main()
       {
           S s1 = S(1, 2, 0, 3, 4);
           S s2 = S(1, 2, 1, 3, 4);
           assert(s1 == s2);
       }

10. Fields with initializers can now be re-initialized in a const constructor:

    You can now initialize a field in a const constructor even if such a field already has an initializer:

        struct S
        {
            bool field = true;

            this(int v) const
            {
                field = false;  // ok
            }
        }

11. Added the isNested trait for discovery of aggregates and functions with context pointers:

    The new isNested trait allows you to discover whether an aggregate or function contains a context pointer:

        void main()
        {
            int x;

            struct S1 { void f() { x++; } }
            static struct S2 { }

            void f1() { x++; }
            static void f2() { }

            static assert(__traits(isNested, S1));
            static assert(__traits(isNested, f1));
            static assert(!__traits(isNested, S2));
            static assert(!__traits(isNested, f2));
        }

12. Templates can now be nested inside of functions:

    void test()
    {
        template ArrayOf(T) { alias ArrayOf = T[]; }
        static assert(is(ArrayOf!int == int[]));
    }

Allowing template's inside of functions will enable better encapsulation and avoid the pollution of module-scoped symbol names.

13. UFCS now works with scoped local imports:

    Functions that are made available through a local import are now picked up when using Uniform Function Call Syntax:

        module foo;
        string concat(string arg1, string arg2) { return arg1 ~ arg2; }

        module test;
        void main()
        {
            import foo;
            assert("foo".concat("bar") == "foobar");  // UFCS now works
        }

    This feature also works for imports within aggregates. Note that local imports have a higher precedence than module-scoped imports.

14. Added __FUNCTION__, __PRETTY_FUNCTION__ and __MODULE__:

    A new set of special keywords were added. Together with __FILE__ and __LINE__ they form a complete feature set that is useful in debugging code:

        module test;
        import std.stdio;

        void test(string file = __FILE__, size_t line = __LINE__, string mod = __MODULE__,
                  string func = __FUNCTION__, string pretty = __PRETTY_FUNCTION__)
        {
            writefln("file: '%s', line: '%s', module: '%s',\nfunction: '%s', pretty function: '%s'",
                     file, line, mod, func, pretty);
        }

        int main(string[] args)
        {
            test();
            return 0;
        }

    The above will output:

        file: 'test.d', line: '13', module: 'test',
        function: 'test.main', pretty function: 'int test.main(string[] args)'

15. DDoc: Deprecated declarations are now wrapped in a DEPRECATED macro:

        module test;

        /// sum function
        deprecated int sum(int x, int y) { return x + y; }

    By default the macro expands to its argument. It can be overriden by the user, for example:

    macros.ddoc:

        DEPRECATED=<del>$0</del>

    The above ddoc file can then be used when the documentation is being generated:

        $ dmd -D -o- test.d macros.ddoc

16. Added documented unittest feature for verifiable code example generation:

    Documented unittests which follow any symbol declarations are now used to generate example sections for the symbol when generating DDOC documentation. Example:

        /// sum function
        int sum(int x, int y) { return x + y; }

        ///
        unittest
        {
            assert(sum(2, 2) == 4);
        }

    The body of the unittest will be part of the documentation of the sum function. This allows the implementor of the function to keep their examples always up-to-date.

    For more information, see the documentation page of documented unittests.

#### Compiler Enhancements

1. Added -main switch which adds an empty main function:

   The -main switch is primarily useful when unittesting libraries:

       module test;

       int sum(int a, int b) { return a + b; }
       unittest
       {
           assert(sum(2, 2) == 4);
       }

   The above library would need a main() function for the unittests to run, and -main can be used for this purpose:

       $ dmd -unittest -main -run test.d

2. Added -cov=percentage switch for minimal coverage tests.

   The -cov switch now has an optional percentage setting which makes the executable emit an error when the coverage doesn't meet the specified requirement:

       module test;

       void test1() { int x = 5; }
       void test2() { int x = 5; }
       void test3() { int x = 5; }

       void main()
       {
           test1();
           test2();
       }

   Example of coverage testing:

       $ dmd -cov=90 test.d
       $ test
       Error: test.d is 80% covered, less than required 90%

3. Added ability to override the mangling of a symbol with a compiler pragma:

   The new pragma(mangle, ...) directive allows you to set a custom mangling for any symbol:

       pragma(mangle, "module") extern(C) void module_();

   The above allows linking to a C function named "module", which ordinarily we wouldn't be able to link to directly since "module" is a reserved D keyword.

#### Phobos Changes

1. std.typecons.scoped implementation changed, potentially breaking some user-code:

   User-code which used the std.traits.ReturnType trait to retrieve the type of a scoped call will have to be changed to use the typeof operator instead:

       class A
       {
           this() {}
           this(int) {}
       }

       class B
       {
           // ReturnType!(scoped!A) a;  // disallowed in 2.063
           typeof(scoped!A()) a;        // rewritten, compiles in 2.063

           this()
           {
               a = scoped!A(1);  // would not compile in 2.062, but works with syntax used for 2.063
           }
       }

   The reason for this change is that the ReturnType trait would retrieve the wrong type when a class had multiple constructors, and this would cause initializing the field to fail.

   Another benefit of the new implementation is that scoped can now be aliased for usability purposes:

       class A
       {
           this(int) { }
       }

       void main()
       {
           alias scoped!A scopeA;
           auto a = scopeA(1);
       }

#### Phobos Enhancements

1. std.process has been redesigned from the ground up and introduces a new API and functionality:

   The new std.process module introduces functionality for invoking processes with custom pipe redirection, the ability to wait for processes to finish, and the ability to kill processes. The full list of features can be found in the std.process documentation.

2. std.getopt can now set booleans to false:

   Example code:

       void main(string[] args)
       {
           bool flag = true;
           getopt(args, &flag);
       }

   When invoked via --flag=false, it will set flag to false.

3. Added ownerTid property in std.concurrency:

   It is now easier to send a message from a child thread to its owner thread. Simply use the ownerTid property to get the owner thread's Tid identifier:

       void fun()
       {
           string res = receiveOnly!string();
           assert(res == "Main calling");

           ownerTid.send("Child responding");  // new
       }

       void main()
       {
           auto child = spawn(&fun);
           child.send("Main calling");

           string res = receiveOnly!string();
           assert(res == "Child responding");
       }

   If the owner thread has exited, accessing ownerTid from any of its child threads will throw a TidMissingException.

Version D 2.062 Feb 18, 2013

#### Language Changes

1. typeof() change:

As a result of fixing Bugzilla 6408, the usage of typeof() and indexing may require changes to user code:

    template ElementTypeOf(T)
    {
        alias typeof(T[0]) ElementTypeOf;
    }

    void main()
    {
        // worked in 2.061 due to a bug
        static assert(is(ElementTypeOf!(int[]) == int));
    }

The expression in typeof(T[0]) used to be wrongly interpreted as the element type of T, however in v2.062 it is interpreted as a static array of element T with length 0. To work around this the user can either use a trait from the standard library, or use the .init property of a type for arbitrary expressions:

    import std.range;

    template ElementTypeOf(T)
    {
        // use T.init
        alias typeof(T.init[0]) ElementTypeOf;
    }

    void main()
    {
        // use std.range.ElementType
        static assert(is(ElementType!(int[]) == int));

        // use custom template after fixing its code
        static assert(is(ElementTypeOf!(int[]) == int));
    }

2. alias syntax change:

The newly introduced "alias foo = int" syntax is not usable with subtyping. This is to prevent confusion from a possible future syntax which would enable aliasing of super constructors. For now, the existing alias syntax can be used:

    struct S
    {
        int x;
        // alias this = x;  // error
        alias x this;
    }

In the upcoming release (v2.063) a new syntax will be introduced:

    struct S
    {
        int x;
        alias this : x;  // new feature in upcoming 2.063
    }

Version D 2.061 Jan 1, 2013

#### New/Changed Features

- DMD now shows deprecated features as warnings by default (a message is displayed but compilation is not halted anymore). There are also 2 new compiler flags: -de, to get the old default behaviour (using deprecated features is an error) and -dw, to explicitly enable the new default behaviour (just warn). This makes it possible to add -de in the configuration file to get the old default and still be able to override that default by using -dw when compiling. The -d flag stays the same (silently ignore deprecated features).

Version D 2.060 Aug 2, 2012

#### New/Changed Features

- std.string: The current implementations of std.string.format and string.sformat are scheduled to be replaced in November 2012 with improved implementations which conform to writef. In some, rare cases, this will break code. Please see the documentation for std.string.format and std.string.sformat for details.
- std.bitmanip: Added peek, read, write, and append for converting ranges of bytes to and from integral types.
- std.container: Added DList, which is an implementation of a doubly-linked list.
- Added std.file.tempDir which returns the path to a directory where a program can put temporary files.
- std.process: Added escapeShellCommand, escapeShellFileName, and escapeWindowsArgument. Documented browse function.
- std.range: Added RefRange, which effectively makes it possible to pass a range by reference.
- std.traits: Added KeyType, ValueType, isScalarType, isBasicType, and SetFunctionAttributes templates.
- std.utf: Added overload of codeLength which operates on a string.
- std.traits: areAllSafe has been scheduled for deprecation. Please use allSatisfy(isSafe, ...) instead.
- clear has been renamed to destroy, and clear (as an alias to destroy) has been scheduled for deprpecation.
- Capitalized std.traits.pointerTarget to PointerTarget. Old one is scheduled for deprecation.
- std.algorithm.indexOf - which was scheduled for deprecation - has been deprecated (it was easily confused with std.string.indexOf). Please use countUntil instead.
- std.cpuid - which was scheduled for deprecation - has been deprecated. Please use core.cpuid instead.
- std.conv.ConvError and ConvOverflowException - which were scheduled for deprecation - have been deprecated. Please catch ConvException and ConvOverflowException instead.
- The overloads of std.conv.to which were scheduled for deprecation because formattedWrite replaced them have now been deprecated. Please use std.format.formattedWrite instead.
- The overload of std.exception.enforce which takes the file and line number as template arguments has been scheduled for deprecation (as it causes unnecessary template bloat). Please use the overload which takes them as function arguments instead. This will have no effect on any calls to enforce which do not explicitly pass the file or line number.
- std.format.FormatError - which was scheduled for deprecation - has been deprecated. Please catch FormatException instead.
- std.file.listDir has been deprecated. Please use std.file.dirEntries instead.
- std.range.replicate - which was scheduled for deprecation - has been deprecated. Please use repeat instead.
- std.range.SortedRange.canFind - which was scheduled for deprecation - has been deprecated. Please use SortedRange.contains instead.
- std.socket: timeval and linger - which were scheduled for deprecation - have been deprecated. Please use TimeVal and Linger.
- std.stdio.isStreamingDevice has been scheduled for deprecation. Please use isFileHandle instead.
- The deprecated std.typecons.defineEnum has been removed.
- UtfException - which was scheduled for deprecation - has been deprecated. Please use UTFException instead.
- The deprecated overloads of std.array.insert and std.array.replace have been removed. Please use insertInPlace and replaceInPlace instead.
- The deprecated toISOExtendedString and fromISOExtendedString functions in std.datetime have been removed. Please use toISOExtString and fromISOExtString instead.
- The deprecated std.file.getTimesPosix has been removed. Please use std.file.getTimes instead.
- The deprecated overloads of isFile, isDir, and isSymLink in std.file which took uint have been removed. Please use attrIsFile, attrIsDir, and attrIsSymlink instead.
- The deprecated std.file.DirEntry.timeStatusChanged has been removed. Please use std.file.DirEntry.attributes to get at that information if you need it.
- The deprecated std.contracts module has been removed. Please use std.exception instead.
- The deprecated std.arg, std.bind, and std.loader modules have been removed.
- Added TypeInfo.rtInfo property to get library defined runtime info.
- Added front end support for AVX 256 bit SIMD instructions.
- Default arguments and parameter identifiers (if any) are added to the tuple generated from IsExpression's __parameters case.
- Changed the way the align attribute works, to make it more usable and comprehensible. Default alignment has not changed.
- The align attribute now accepts arbitrary powers of two. This affects layout of static data, too. Such effects are dependent on limitations of the object file format - currently Win32 programs cannot align on larger than 16 byte boundaries.
- HTML input file support completely removed.
- Bugzilla 3150: cast from dynamic array to ulong is allowed
- Bugzilla 3866: anonymous delegate with default parameters cross-talks to another anonymous delegate
- Bugzilla 4174: Template interface functions not allowed, making operator overloads difficult

Version D 2.059 Apr 12, 2012

#### New/Changed Features

- Add predefined Ddoc macro SRCFILENAME
- Changed lexer to support # as a token, preserving #line's original behavior
- added AES, PCLMULQDQ, RDRAND, AVX, VAES, VPCLMULQDQ, FMA, FP16C to core.cpuid
- Bugzilla 435: Constructors should be templatized
- Bugzilla 2367: Overloading error with string literals
- Bugzilla 3382: [tdpl] Implement uniform function call syntax
- Bugzilla 4536: Typetuples (T...) should have an .init member
- Bugzilla 5525: Eponymous templates should allow for overloaded eponymous members
- Bugzilla 7105: relax inout rules
- Bugzilla 7833: Changelog should clearly mention struct literal/opCmp/opEquals/toHash changes
- Strive to make toHash, toString, opEquals and opCmp functions pure, nothrow, const and @safe. Soon, this will become a requirement.
- The deprecated std.date, std.dateparse, and std.gregorian modules have been removed. Please use std.datetime instead.
- Several deprecated functions in std.file have been removed.
- The old functions in std.path which were scheduled for deprecation have now been deprecated. Please use the new ones which were introduced in 2.055. However, note that curdir and pardir do not have replacements, because they're "." and ".." respectively on all OSes so variables for them were seen as unnecessary. Also, one major change to note about the new std.path functions is that when operating on extensions, they expect "." to be part of the extension whereas the old ones did not (e.g. "file.txt".extension == ".txt" whereas "file.txt".getExt() == "txt").
- The version of std.exception.enforceEx which was scheduled for deprecation has been deprecated. Please use the version which takes exceptions which can be constructed with new E(msg, file, line) (rather than just new E(msg) as the old version did). That way, exceptions constructed with enforceEx will give the file and line number where enforceEx was called.
- Get rid of Win9x support.
- std.typecons: Added Proxy mixin template.
- std.format: Added documentation about compound format specifier.

Version D 2.058 Feb 14, 2012

#### New/Changed Features

- Add new => lambda syntax.
- Allow 1.userproperty syntax. NOTE: 1.f is no longer a float literal, add a 0.
- Convert to -shared dmd switch instead of -dylib
- Better use of XMM registers in OS X 32 bit target.
- Add inline assembler support for AVX instructions (64 bit targets only).
- Use of base class protection is now deprecated.
- Added traits isVirtualMethod and getVirtualMethods.
- Struct/class invariants are now implicitly const.
- Major overhaul of std.regex module's implementation. Breaking change in std.regex.replace with delegate, use Captures!string instead of RegexMatch!string as delegate parameter.
- As typedef has been deprecated, overloads of std.conv.to which use typedef have now been deprecated.
- std.array.insert has been deprecated. Please use std.array.insertInPlace instead.
- The overload of std.array.replace which replaces in place has been deprecated. Please use std.array.replaceInPlace instead.
- The toISOExtendedString and fromISOExtendedString functions on SysTime, Date, TimeOfDay, and DateTime in std.datetime have been deprecated. Please use toISOExtString and fromISOExtString instead.
- std.file.getTimesPosix has been deprecated. Please use std.file.getTimes instead.
- The overloads for isDir, isFile, and isSymlink in std.file which take a uint have been deprecated. Please use attrIsDir, attrIsFile, and attrIsSymlink instead.

Version D 2.052 Feb 17, 2011

#### New/Changed Features

- 64 bit support for Linux
- Implemented exception chaining, as described in TDPL. Currently Windows-only.
- std.random: Added Xorshift random generator
- Support HTML5 entities
- Added std.datetime for handling dates and times. std.date and std.gregorian are now scheduled for deprecation. Any functions in other modules of Phobos which used std.date.d_time have been changed to use std.datetime.SysTime or are scheduled for deprecation with new functions with the same functionality added which use SysTime (done in cases where switching existing functions to use SysTime would have broken code). New code should use std.datetime instead of std.date.
- Various functions in std.file were renamed to match Phobos' naming conventions (e.g. isFile instead of isfile). The old names are aliased and scheduled for deprecation.

Version D 2.029 Apr 19, 2009

#### New/Changed Phobos

- std.algorithm
  - Everything converted to ranges. Big disruption. Algorithms added.
- std.array
  - Range primitives for arrays
  - Appender template
  - insert, replace functions
- std.bitmanip
  - Bitfields of length 0 are defined to be always 0.
  - The read functions for bitfields are const.
- std.contracts
  - enforce accepts const(char)[] instead of string
  - Added enforce overload that invokes a delegate on failure
  - Added assumeSorted template
  - Added structuralCast that implements, well, structural casting (incomplete).
- std.conv
  - Rewrote conversions with constrained templates.
  - Added text() function that transforms everything into text.
- std.date
  - Added a benchmark function that allows for simple timing measurements.
- std.file
  - read, write, append, rename, remove, getSize, getTimes, getAttributes, isfile, isdir, chdir, mkdir, mkdirRecurse, rmdir, listdir, copy, take filename(s) by "in char[]"
  - Added function readText that reads and validates a text file
  - Added function slurp that reads a file into an array of tuples. Example:

        auto a = slurp!(int, double)("filename", "%s, %s");

    Each line in the file looks like e.g. "1, 2.3". slurp returns an array of Tuple!(int, double) with the parsed content.
- std.format
  - Added vector parsing and printing with the specifier "%()". For example, writefln("[%(s; )]", [1, 2, 3][]) writes "[1; 2; 3]". This support is experimental and may be changed in the future.
  - Added a formattedRead function (i.e., scanf that doesn't suck). The implementation is incomplete but common cases are supported.
- std.functional
  - Improved error messages
  - Added configurable parameter names for functions as strings
  - Added Adjoin template
- std.getopt
  - Added support for parameterless delegates
- std.math
  - Intrinsics std.math.yl2x and yl2xp1 added. Improves performance of std.math.log() and similar functions (and they are now pure nothrow).
- std.mmfile
  - Minor cosmetic changes
- std.numeric
  - Added type CustomFloat that allows defining specialized floating-point numbers (e.g. 16-bit floats, positive floats etc.)
  - Added FPTemporary as the best type to store temporary values.
  - Templatized oppositeSigns
  - Added Euclidean distance
  - Added dotProduct
  - Added cosineSimilarity
  - Added normalize
  - Added string kernel functions gapWeightedSimilarity, gapWeightedSimilarityNormalized, gapWeightedSimilarityIncremental.
- std.outbuffer
  - Added a few missing overloads of write()
- std.path
  - getDrive now works with all string types
  - isabs accepts in char[]
  - join accepts variadic in char[]
  - fnmatch works with in char[]
- std.random
  - Added RandomCover that covers a given range in a random manner
  - Eliminated the old-fashioned random functions
  - Defined a default random object that simplifies calls to the random functions
  - Changed generators to obey the range interface. So now you can write:

        Random r;
        foreach (n; take(100, uniform(0, 100))) { ... }

- std.range (new file)
  - Range manipulation stuff.
- std.regex (new file)
  - Regular expression library with wide char support, simplified interface, better speed etc.
- std.regexp
  - Scheduled for deprecation. Use std.regex instead.
- std.stdio
  - Major breaking changes: introduced the File struct. Now stdin, stdout, stderr are instances of the File struct.
  - Due to bugs in the compiler, the copy constructor and destructor of File are commented out. Walter will look into fixing the issues soon. File should work fine, but you need to close it manually.
  - A byRecord iteration mode makes it pretty easy to iterate structured text files.
  - writef and writefln now require a string as their first argument.
- std.string
  - strip, stripl, stripr, startsWith, endsWith now work with any string type
- std.typecons
  - Added constructors, assignment operator, length, toString, and slice to Tuple.
- std.utf

Version D 2.025 Feb 14, 2009

#### New/Changed Features

- Added Mac OSX support.
- Separated bin and lib directories into windows, linux, and osx.
- No longer need to download dmc to use the windows version.
- Use version(OSX) for Mac OSX. Although version(darwin) is also supported for the time being, it is deprecated.

#### Bugs Fixed

- Bugzilla 2448: template return by reference causes seg fault

Version D 2.023 Jan 2, 2009

#### New/Changed Features

- Improved speed of long division.
- Optimizer now takes advantage of immutable and pure.
- Added predefined version D_Ddoc which is predefined when -D switch is thrown.
- the type of a string literal is now invariant(char)[] rather than invariant(char)[length_of_string]. It is still implicitly convertible to the latter. This is intended to reduce template instantiation bloat.
- Undid fix for Bugzilla 2500, as the fix was arguably worse than the bug.

#### Bugs Fixed

- Bugzilla 1078: Frontend uses of 'auto' where 'scope' should be used
- Bugzilla 2517: DDoc omits abstract on classes
- Bugzilla 2518: scope(success) not execuate and RAII variable destructor is not called

- Bugzilla 2542: array casts behave differently at compile and runtime

Version D 2.022 Dec 11, 2008

#### New/Changed Features

- Changed IUnknown to use the extern(System) interface rather that extern(Windows).
- Pure functions now get semantically checked.
- Nothrow functions now get semantically checked.
- shared is now a type constructor.

#### Bugs Fixed

- Bugzilla 1518: Crash using 'scope', 'with' and undefined 'RegExp'

- extern __thread now works on Linux.

Version D 2.021 Nov 25, 2008

#### New/Changed Features

- Added -safe switch and module(system) Identifier; syntax.
- Added range support to foreach statement.
- scope parameter storage class means the parameter will not 'escape' the scope of the function invocation. Using this for delegate parameters will prevent some closure allocations by the calling function.
- The lazy storage class now implies scope so that lazy arguments won't trigger a heap allocated closure.
- The 'this' parameter to struct member functions is now a reference type, rather than a pointer. This breaks existing code.
- More changes to druntime:

  from | to
  --- | ---
  OutOfMemoryException | OutOfMemoryError
  SwitchException | SwitchError
  HiddenFuncException | HiddenFuncError
  ArrayBoundsException | RangeError
  AssertException | AssertError
  FinalizeException | FinalizeError
  onArrayBoundsError | onRangeError
  stdc.* | core.stdc.*
  sys.* | core.sys.*

- Added core.runtime.loadLibrary() as an experimental feature for loading dynamic libraries (Win32 only at the moment).
- Added core.runtime.unloadLibrary() as an experimental feature for unloading dynamic libraries previously loaded by loadLibrary().
- core.thread.sleep() accepts a long integer specifying the sleep interval in 100 nanosecond intervals (the previous release notes said this was a float, IIRC).
- It is no longer necessary to link in druntime separately, it is inserted into libphobos2.a.

#### Bugs Fixed

- Bugzilla 313: Fully qualified names bypass private imports
- Bugzilla 920: SPEC: Auto classes referenced where scope should be used
- Bugzilla 929: Resizing array of associative arrays (uint[char[]][]) causes infinite loop / hang
- Bugzilla 1372: Compiler accepts pragma(msg,)
- Bugzilla 1610: Enum.stringof is int, not the name of the enum

- Bugzilla 2431: Internal error: ../ztc/cgcod.c 1031 when using -O
- Bugzilla 2470: Cannot build libraries from other libraries
- unittest functions now always use D linkage

Version D 2.020 Oct 20, 2008

#### New/Changed Features

- Improved performance of AAs by rebalancing trees when rehashing.
- immutable now is implemented.
- Bugzilla 2344: Two wrong lookups for array functions
- Bugzilla 2345: Return by reference should be allowed
- Posix is now a predefined identifier when compiling under Linux
- Based on Sean Kelly's hard work, Phobos has been split into two libraries, druntime.lib and phobos.lib. This will enable better integration with Tango. The user source code changes are:

  from | to
  --- | ---
  bit | bool
  _d_OutOfMemory() | onOutOfMemoryError()
  import std.asserterror; | import core.exception;
  import std.hiddenfunc; | import core.exception;
  import std.switcherr; | import core.exception;
  import std.array; | import core.exception;
  import std.outofmemory; | import core.exception;
  import std.gc; | import core.memory;
  import std.thread; | import core.thread;
  SwitchError | SwitchException
  AssertError | AssertException
  HiddenFuncError | HiddenFuncException
  ArrayBoundsError | ArrayBoundsException
  std.gc.fullCollect() | GC.collect()
  std.gc.*() | memory.gc_*()
  _moduleUnitTests() | import runtime; runModuleUnitTests()
  printf | add import std.c.stdio;

  Changes to thread:
  - The thread handle isn't exposed to the user. This can always be obtained using the appropriate OS calls from within the thread.
  - There is no druntime equivalent for Thread.pause() and Thread.resume(). The closest is thread_suspendAll() and thread_resumeAll()--extern (C) calls meant for use by the GC.
  - Thread.wait() is renamed to Thread.join().
  - Sleep functionality is available as Thread.sleep(double), where the parameter represents the number of seconds to sleep (fractional values accepted, obviously).
  This is a big change, and expect some problems for a release or two with this.

- Rewrote the rdmd utility to properly track dependencies and command-line compiler options (currently only working under Linux).
- Changed the Phobos makefile linux.mak to take advantage of the new -lib feature. Improved full build speed by 3x.
- std.algorithm: Changed the map() function so that it deduces the return type. Also map can be now curried.
- std.contracts: Added file and line information to enforce. Added errnoEnforce that formats the error message according to errno. Added corresponding ErrnoException class.

- Added predefined version(unittest). See Bugzilla 458
- Removed std.math2
- Added compile time error for comparing class types against null.

- std.algorithm: Made some imports conditional for the Unittest version; fixed doc typo; made min and max always return the tightest type and work with mixes of signed and unsigned; changed enum value names to obey lowercase convention; changed OrderStrategy to SwapStrategy as it's not just for ordering (e.g. see eliminate).
- std.bitmanip: simplified code generated for bitfields and improved error message.
- std.format: ate dogfood: used bitfields internally.
- std.functional: fixed binaryfun to work with constant-size arrays; added compose.
- std.random: made unpredictableSeed return different numbers every call (except for rarely-encountered MT scenarios); added private variable name that will take experts millenia to figure out; changed the boundaries syntax from two separate characters '[', '(' to one string "[(" throughout.
- std.traits: added mostNegative, mostly to assuage for the unpardonable mistake of inheriting C++'s unpardonable mistake of defining "min" to mean very different things for floating-point types and integral types.
- std.typecons: added undocumented Rebindable in preparation for opImplicitCast.
- std.math:
  - Support for different CPU IEEE 'real' formats: 64-bit, 80-bit and 128-bit (quadruple) reals, both BigEndian and LittleEndian; partial support for non-IEEE 'doubledouble' reals.
