dimgigov 9dd964dc48 test: add fibonacci golden test, expand GOLDEN_TESTS 2026-06-07 16:10:05 +03:00
dimgigov 1f0baefa5a feat: add selfhost-loop determinism check, golden tests, improve sema diagnostics 
- Makefile: new targets `test-golden` and `selfhost-loop`
  - selfhost-loop verifies C codegen determinism (2-pass bootstrap)
  - test-golden compares C output against expected.c golden files
  - Updated clean-all to clean new build dirs
- tests/golden/hello/: first golden test (hello world)
- src/sema.bux:
  - Fix: import stubs only registered if symbol doesn't already exist
  - Improve: error message now includes identifier name

dimgigov 2698ca92b7 fix(selfhost): stdlib path + merge all modules, not just imports 
- Fix Cli_FindStdlibDir: search for lib/ instead of stdlib/
- Fix Cli_CollectStdlibImports → merge ALL lib/*.bux via bux_list_dir
- Fix Cli_CollectStdlibImports path: remove Std/ subdir (now flat)
- Add ../../ fallback for rt/ paths (build/selfhost depth)
- Update PLAN.md with v0.3.0 structure + v1.0.0 roadmap
- Remaining: 7 sema cross-module resolution bugs (pre-existing)

dimgigov 9c6b516453 feat: restructure repo, borrow checker, expanded stdlib 
- Reorganize repository to Rust-style layout:
  compiler/bootstrap/  compiler/selfhost/  compiler/tests/
  library/std/  library/runtime/  tests/  tools/
- Add buxs/ Windows-compatible project root
- Add borrow checker tests and implement:
  - Alias analysis (double mutable borrow detection)
  - Use-after-move detection for own T
- Expand standard library:
  - Std::Os: Args, Env, Cwd, Chdir
  - Std::Time: NowMs, NowUs, SleepMs
  - Std::Process: Run, Output
  - Std::Io: PrintInt64 (fixes 32-bit truncation bug)
- Add examples: os_time.bux, process.bux
- Fix PrintInt to use int64_t in C runtime

dimgigov 975cc347d0 fix: selfhost CLI run command, lexer char literal, parser test path, calloc in runtime 
- Fix lexer unterminated char error test (was treating 'a as lifetime)
- Fix parser test sample.bux path for root-dir execution
- Add bux_system() to runtime.c and run command to selfhost CLI
- Switch bux_alloc from malloc to calloc for zero-init
- Fix module flattening in Cli_Check/Cli_Compile to scan full decl list
- Make test passes fully, selfhost builds successfully

dimgigov 2b911410cb feat: self-hosting progress - Nim backend, parser fixes, 64 struct fields, 13/14 modules check 2026-06-01 23:42:25 +03:00
dimgigov 8e255b2125 feat: Phase 8.2, 8.4, 8.5, 9.1 + C backend fixes 
Phase 8.2 — Gradual Ownership:
- Add tkRef/tkMutRef types and `mut` keyword
- Add @[Checked] attribute for opt-in borrow checking
- Reject assignment through &T in checked functions
- examples/ownership.bux

Phase 8.4 — CTFE:
- Evaluate const func at compile-time via evalExpr/evalBlock
- Fold const declarations to literals; emit #define in C
- examples/ctfe.bux (Factorial(10) → 3628800)

Phase 8.5 — Trait Bounds:
- Change declFuncTypeParams from seq[string] to seq[TypeParam] (name + bound)
- Parser handles <T: Comparable>
- Sema checks typeImplements at call sites
- Fix C backend: generic receivers + pointer self field access
- examples/trait_bounds.bux

Phase 9.1 — Package Manager:
- Inline tables/arrays in TOML parser
- bux add, bux install, bux.lock generation
- Dependency resolution with git/path sources
- Build pipeline merges dependency .bux sources

C Backend Fixes:
- resolveExprType(ekIdent) now applies typeSubst for generic params
- Method desugaring works for monomorphized generic receivers
- Pointer checks use isPointer (covers tkRef/tkMutRef)
- Field access on &T emits -> instead of .

Remove accidentally committed test binaries from tracking

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 7ee6a73ea4 feat: Std::String, Std::Map, Result/Option, ? operator, sizeof fix, docs

- Std::String: strlen, strcmp, concat, copy, starts_with wrappers
- Std::Map: linear-probing hash map with String keys, int values

Add error handling:
- Result and Option algebraic enum examples
- ? try operator for automatic error propagation in HIR lowering

Compiler bugfixes:

- Fix let statement lowering for pointer types (*char8 → int* bug)
- Fix PrintInt ABI mismatch (int64_t → int in io.c)
- Fix Makefile test bug (_test_tmp_pkg already exists)

Documentation:
- Rewrite README.md with features, examples, project structure
- Add docs/LanguageRef.md — complete language reference
- Add docs/Stdlib.md — standard library documentation
- Add docs/BuildAndTest.md — build and test guide

New examples: strings, map, result_option, try_operator (13 total)

  - 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
