0.6.5 Change list

Changes / improvements

• Allow splat in initializers.
• Init command will now add test-sources to project.json #1520
• a++ may be discarded if a is optional and ++/-- works for overloaded operators.
• Improve support for Windows cross compilation on targets with case sensitive file systems.
• Add "sources" support to library manifest.json, defaults to root folder if unspecified.
• Add char_at method in DString and operators [], len, []= and &[].
• Add -q option, make --run-once implicitly -q.
• Add -v, -vv and -vvv options for increasing verbosity, replacing debug-log and debug-stats options.

Fixes

• Fix bug where a > 0 ? f() : g() could cause a compiler crash if both returned void!.
• @builtin was not respected for generic modules #1617.
• Fix issue writing a single byte in the WriteBuffer
• A distinct inline pointer type can now participate in pointer arithmetics.
• Support &a[0] returning the distinct type when applying it to a distinct of a pointer.
• Fix error when calling HashMap.remove on uninitialized HashMap.
• Fix issue with resolved try-unwrap in defer.
• Fix issue with overloaded subscript and ++/-- and assign ops (e.g. *=)
• Fix issue with properties in different targets not being respected #1633.
• Indexing an Optional slice would crash in codegen #1636.
• SimpleHeapAllocator bug when splitting blocks allowed memory overrun.
• Not possible to alias or take reference for extension methods on non-user defined types. #1637
• Prevent methods from using names of properties or fields. #1638
• b64 / hex data strings can now be used with ` as well.
• Contracts on generic modules would evaluate too late, sometimes not catching the error until it already occurred elsewhere.
• Fix bug preventing optionals from being used in ranges or as indices.
• Crash compiling for arm64 when returning 16 byte and smaller structs by value not a power of 2 #1649.
• Enforce single module compilation for static libraries to make constructors run properly.
• Crash when using --no-obj without compile-only. #1653
• Do not produce expression locations for windows.
• Issue where multiple methods were accepted for the same type.
• Issue where a method was linked to a type alias instead of the underlying type.
• Fix Fnv1a encoding.
• Fix issue with accessing arrays in access-overloaded types, e.g. list[1][2] #1665.
• Cast removing arbitrary array indices and converting them to pointers should always be fine #1664
• Incorrect "no-libc" definition of cos, making it unavailable for wasm.
• Fix issue with the adjoint and inverse calculations for Matrix2x2.
• It was possible to create 0 length arrays using byte literals. #1678
• Crash when a constant null typeid is checked for properties. #1679

Stdlib changes

• Add io::MultiReader, io::MultiWriter, and io::TeeReader structs.
• Updated Base32 API.
• Add file::save.
• Add memcpy / memset / memcmp to nolibc.
• Add sort::quickselect to find the k-th smallest element in an unordered list.
• Add sort::is_sorted to determine if a list is sorted.
