0.17.0

2025-10-15

Changes / improvements

• Added WASM support via emscripten compiler

• Added - #define cex$enable_minimal allowing to use only bare minimum on CEX functionality, and selectively re-enable some of the parts. This opens opportunities for CEX embedded portability: freestanding example.

• Removed: (breaking) io.fileno - removed, it's non-standard and platform specific function
• Added cex$is_freestanding macro

Fixes

• Fixed memory alignment for HeapAllocator bug when system malloc() returns non 16-byte aligned ptr

2025-05-16

Changes / improvements

• (breaking) cexy.src_changed() - refactored with array length argument

• cexy.app.find_app_target_src - refactored arguments
• Examples: added building/linking with system libs
• cexy - Added support of vcpkg libs
• Examples: added building/linking with vcpkg libs
• refactor!: removed all const qualifiers from the cex project
• feat: added __builtin_unreachable() after assert/panic

Fixes

• os.match - fixed [A-Z+]* pattern invalid match at the beginning

• fix(cexy): fix cexy.src_include_changed() was not searching relative to src file
• fix(cexy): pkgconf fixed include dirs flags before linker
• fix: mingw warning visibility attribute not supported in this configuration

• fix(cexy): ./cex process all - ignores build/ and tests/ now

Changes / improvements

• Code base cleanup

• Added Valgrind to CI (extra memory leak check, uninitialized variables check, file handle leaks checks) + available on non x86 architectures
• os.path.abs() - getting absolute path from any other path
• cex help - added code syntax colors in terminal
• json - added new JSON parser/builder into cex.h core
• str$convert() - typesafe generic macro for converting char*/str_s to any basic numeric type
• cex stats - added new command for calculating project lines of code + quality stats
• cexy$pkgconf_libs - new universal way of using dependencies in CEXY build system (tests and apps). Uses system (or custom) pkgconf command for resolving library settings and compiler args.
• cexy$pkgconf_libs - required libs now checked in cex config, user will receive diagnostic error if anything is missing
• ./cex - added compile_flags.txt generation for clangd LSP/tooling (if that file exists)
