0.7.7 Change list

Changes / improvements

• Error when using $vaarg/$vacount/$vasplat and similar in a macro without vaargs #2510.
• Add splat defaults for designated initialization #2441.
• Add new builtins $$str_snakecase $$str_replace and $$str_pascalcase.
• "build-dir" option now available for project.json, added to project. #2323
• Allow .. ranges to use "a..a-1" in order to express zero length.
• Disallow aliasing of @local symbols with a higher visibility in the alias.
• Add --max-macro-iterations to set macro iteration limit.
• Improved generic inference in initializers #2541.
• "Maybe-deref" subscripting foo.[i] += 1 #2540.
• ABI change for vectors: store and pass them as arrays #2542.
• Add @simd and @align attributes to typedef #2543.
• Rename @extern to @cname, deprecating the old name #2493.
• Allow (Foo)0 bitstruct casts even if type sizes do not match.
• The option --riscvfloat renamed --riscv-abi.
• Add initial --cpu-flags allowing fine grained control over CPU features.

Fixes

• Bug in io::write_using_write_byte.
• Bitstruct value cannot be used to index a const array in compile time. #2512
• Compiler fails to stop error print in recursive macro, and also prints unnecessary "inline at" #2513.
• Bitstruct truncated constant error escapes $defined #2515.
• Compiler segfault when accessing member of number cast to bitstruct #2516.
• Compiler assert when getting a member of a bitstruct : char @bigendian #2517.
• Add ??? and +++= to list-precedence.
• Fix issues with linking when using symbol aliases. #2519
• Splatting optional compile-time macro parameter from inside lambda expression does not work #2532.
• Compiler segfault when getting a nonexistant member from an unnamed struct #2533.
• Correctly mention aliased type when method is not implemented #2534.
• Regression: Not printing backtrace when tests fail for MacOS #2536.

Stdlib changes

• Sorting functions correctly took slices by value, but also other types by value. Now, only slices are accepted by value, other containers are always by ref.
• Added @str_snakecase, @str_replace and @str_pascalcase builtin compile time macros based on the $$ builtins.
• Add TcpSocketPair to create a bidirectional local socket pair.
• Add extern fn CInt socketpair(AIFamily domain, AISockType type, CInt protocol, NativeSocket[2]* sv) binding to posix.
• Add extern fn getsockname(NativeSocket socket, SockAddrPtr address, Socklen_t* address_len) binding to win32.
