dimgigov 48ee40e7c5 feat: struct init in all phases, 9/14 modules pass check 2026-05-31 20:21:20 +03:00
dimgigov e8084b2840 Phase 7.10: command-line args + buxc2 check/build working 
Runtime:
- bux_argc()/bux_argv() — command-line arg access from Bux programs
- g_argc/g_argv globals — set by C main() wrapper

Compiler:
- C backend generates extern g_argc/g_argv + int main(argc,argv) wrapper
- main.bux reads args via bux_argc/bux_argv and passes to Cli_Run

buxc2 verified:
- buxc2 version — reads CLI args correctly
- buxc2 check <file.bux> — lexes, parses, type-checks, generates C
- buxc2 build <file.bux> <output.c> — writes C output

PLAN.md updated with Phase 7.10 status and remaining work.
All 18 examples pass, all unit tests pass.

dimgigov cb256397bd Phase 7.9: Self-hosted compiler buxc2 builds and runs! 🎉 
buxc (Nim bootstrap) successfully compiles buxc2 (Bux self-hosted compiler)
into a working 88KB ELF x86-64 binary.

Compiler fixes (Nim):
- duplicate symbol: user funcs shadow stdlib funcs via mergeDecls()
- forward declarations: func without body + definition (both orderings)
- extern func dedup: same extern in multiple files
- discard keyword: new language keyword, lowered to expr stmt or no-op
- parser: keywords as field names + advance-on-error safeguard
- parser: var without initializer (zero-init)
- parser: multi-line || && continuation expressions
- parser: else-if chain newline handling
- C backend: const declarations emitted as #define
- C backend: load(field_ptr) → base.field optimization (fixes lvalue errors)

Source fixes (src_bux/*.bux):
- types.bux: tk* → ty* prefix for type kind constants (avoid token conflict)
- sema.bux: remaining tk* → ty* references, StringMap → *void workaround
- hir_lower.bux: ekReturn removed, Lcx_LowerParam helper, *f dereference
- c_backend.bux: &mod.funcs[i] for pointer passing
- cli.bux: ReadFile/WriteFile → bux_read_file/bux_write_file wrappers
- parser.bux: pathStr.len → String_Len(pathStr)
- types.bux: "*" + x → String_Concat("*", x)

Build system:
- Makefile: added 4 missing examples + selfhost target
- PLAN.md: updated with actual project state, Phase 7.9 marked complete

All 18 examples pass, all unit tests pass.

dimgigov 8e74215378 feat: add HIR, C backend, and end-to-end compilation 
- Phase 3: High-Level IR (HIR) with lowering from AST
  - Method call desugaring (obj.method() → Type_method(obj))
  - if/else, while, loop, break, continue lowering
  - struct, enum, function lowering
  - 8 HIR tests passing

- Phase 5A: C backend code generation
  - Type mapping (Bux types → C11 types)
  - Expression and statement emission
  - Struct, enum, function generation
  - C main() wrapper for Bux Main()

- Runtime shim (stdlib/runtime.c)
  - bux_alloc, bux_free, bux_print, bux_panic
  - BuxString, BuxSlice types
  - Bounds checking, division by zero

- Build integration
  - bux build: lex → parse → sema → HIR → C → cc
  - bux run: build + execute
  - bux clean: remove build directory

- Parser fixes
  - Newline handling in struct, enum, extend, interface blocks
  - self keyword as expression and parameter name

- Sema improvements
  - Method resolution (extend blocks)
  - Interface conformance checking
  - collectGlobals made public

- All 70 tests passing (25 lexer + 16 parser + 21 sema + 8 HIR)
- End-to-end: Bux programs compile to native ELF64 binaries
