0.6.4 Change list

Changes / improvements

• Const vector -> const slice implicit conversion.
• Slicing arrays, slices and bytes at compile time Slicing arrays, slices and bytes at compile time #1466.
• Better error for int a[4] = .... Error quality of life: Common C porting bug has an unusual error #1518
• Better error for int Foo(int a) declarations Error quality of life: detecting function like signature is fooled by a spurious semi-colon #1516
• Improve error message in the case of MyInterface x = foo; error quality of life: interface arguments require a pointer to the struct implementing them #1522
• Deprecate @adhoc, allow non-nested ad hoc generic types.
• Constant bytes <=> char[] conversion should work Constant bytes <=> char[] conversion should work #1514.
• Infer now works across ternary.
• Interfaces now support .ptr and .type directly without casting to any.
• Switch to <* *> docs.
• Improve error messages on expressions like var $type = int; Error quality of life: macro var declaration variable must be a capital but not made very clear #1553.
• Disallow casting a void* to any or an interface, unless it is null.
• Defer resolution of declarations when looked up in def aliased Error with symbol resolution  #1559.
• Adding constants to the Json AST AST JSON: Constants are not present #1540
• Adding info to the globals inside Json AST AST JSON: Globals are only qualified names #1541
• Null-check function pointer invocation running null function pointer does not give a backtrace like dereferencing a null variable pointer #1573.
• string::new_struct_to_str and io::struct_to_format to dump struct data.
• io::print will now print structs.
• Improve error message when using void aliases as variable storage type.
• Add a target type: "prepare" which doesn't compile anything (but may run exec)

Fixes

• Unsupported int[*] $x = { 1, 2, 3, 4 } Unsupported int[*] $x = int[4] { 1, 2, 3, 4 }; #1489.
• Unexpected compile error using a typed constant with copysign Unexpected compile error using a typed constant #1517
• Incorrect subscript resolution Detecting if variable is a List in a macro #1519.
• Segfault with passing a program with - using stdin.
• Using no module with - would reject the program.
• Unintended deref of pointers with methods caused regression with hash function.
• Fix broken sincos function.
• Bug when a continue is copied in a defer.
• Compiler error when any/interface initialized using {} compiler errors with all generic types when using interface as type #1533.
• Bug when defers and $if were combined in a macro, which would cause miscompilation.
• Fixes to the CSV reader.
• Crash returning struct or vector from function using ternary expression returning struct or vector from function using ternary expression without explicitly stating type causes compiler to crash with SIGSEV #1537.
• Improved error message on invalid subscript index type quality of life: typo on variable name gives an unexpected error #1535.
• Improved error message when declaring a variable void!.
• Cannot use void as a generic parameter Cannot use void as a generic parameter #1546
• Interfaces not correctly copied with generics segmentation fault using generic module type argument in Interface #1545
• Memory leak in keys.new_list fixed.
• Standard library is now correctly weakly linked, fixing the use of C3 .so together with executable. Issue linking dynamic library produced by c3 #1549, Standard library should implicitly use "weak odr" #1107.
• Wrong error message for interface methods with body adding body to a function in an interface declaration results in Error: An 'extern' function may not have a body. #1536.
• Empty expression block would crash compiler with debug on empty fn void() lambda causes compiler SIGSEV #1554.
• Improve infer conversions on constants, e.g. ZString a = foo ? "a" : "b"; String literal not converted to ZString when in ternary operator #1561
• Show error when declarations do not start with fn in interfaces. Interface parse with Assertion failed #1565
• if (try foo) was handled incorrectly inside a defer.
• &self argument not implicitly null checked. Target object of method is not null checked #1556.
• (uptr)&((Foo*)null).a incorrectly inserts a null check. Taking the address of a member of a struct for a pointer that is null crashes on Windows #1544
• Incorrect error message when $eval is provided an invalid string. $eval("foo()") fails with message Error: Only valid types may be resolved with $evaltype. #1570
• HashMap.copy_keys did not properly copy keys which needed to be allocated copy out keys also in HashMap.copy_keys #1569
• Named vector component access would not fold at compile time. constant vectors not considered to be a compile time constant #1574
• $define would occasionally not properly evaluate declarations it encountered.
• Fixes with error handling recursive @tag errors when using @tag to give a type definition a tag value of its own type #1583.
• Sometimes generating introspection info would not be in the global scope causing a crash LLVM ERROR: Unsupported expression in static initializer #1586.
• @tag on macros cannot be retrieved with tagof @tag attribute is allowed on macros but value cannot be retrieved with tagof #1582
• Taking the $typeof of a wildcard optional returns void!.

Stdlib changes

• Remove unintended print of char[] as String
• Add read/write to stream with big endian ints.
• Move accidently hidden "wrap_bytes".
• Added CBool Type suggestion: CBool #1530.
• Added encoding/base32 module.
