dimgigov 42041dfd74 feat: async functions with return values
- runtime: bux_async_return(value, size) copies result to task->result
- runtime: bux_async_await returns void* result pointer
- runtime: bux_async_result(handle) to retrieve result
- sema: ekAwait returns *void
- HIR: await lowered to bux_async_await returning *void
- Example: async Compute() -> int with interleaved execution and result await

dimgigov 5ec755743d feat: Phase 8.3 true non-blocking async/await with stackful coroutines
- C runtime: ucontext-based coroutines (bux_async_spawn/yield/await/run)
- Round-robin scheduler in bux_async_run() manages ready queue
- spawn Func() without args → bux_async_spawn() creates coroutine
- await → blocks/yields until coroutine completes
- async func → emitted as regular C function, runs on dedicated stack
- Interleaved execution: multiple coroutines yield cooperatively
- Example: examples/async.bux demonstrates WorkA/WorkB interleaving
- All 20 examples pass, selfhost build works

dimgigov d337ada4d6 feat: Phase 8.3 async/await syntax + runtime
- AST: declFuncIsAsync flag, ekAwait expression kind
- Parser: async func declarations, expr.await postfix operator
- Sema: allow await anywhere (blocks current thread until task completes)
- HIR: ekAwait lowered to bux_task_join(handle) call
- C backend: async func emitted as regular function
- Example: examples/async.bux + examples_pkg/async project
- All 20 existing examples pass, selfhost build works

dimgigov ac8b25935f feat: Phase 8.3 Concurrency — tasks, channels, spawn
- Add async/await/spawn keywords to lexer
- C runtime: pthread wrappers (bux_task_spawn, bux_task_join, bux_task_sleep)
- C runtime: mutex/condvar channel implementation (bux_channel_new/send/recv/close/free)
- Build command adds -pthread flag for C compilation
- Std::Task module: TaskHandle, Task_Spawn, Task_Join, Task_Sleep
- Std::Channel module: generic Channel<T> with Send, Recv, Close, Free
- Parser: spawn Expr() expression
- Sema: ekSpawn returns *void
- HIR: hSpawn node lowered from ekSpawn
- C backend: emit bux_task_spawn(FuncName, arg) for spawn expressions
- Example: examples/concurrency.bux (thread + channel demo)
- Example: examples_pkg/concurrency working project

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 5c1a00cbd6 Phase 5-7: generic inference, extend Type<T>, String stdlib, Map<K,V>, self-hosting audit, docs update 2026-05-31 13:06:29 +03:00
dimgigov af14f392f6 feat: generic methods on generic structs + method call auto-addressing
- Auto-register func Type_Method<T>(self: *Type<T>) as methods in sema
- Add type param awareness to sema resolveType for generic function bodies
- Add lazy monomorphization for generic struct method calls in HIR lowering
- Track varTypeExprs in LowerCtx for local variable type inference
- Fix ekSelf in both sema and hir_lower to resolve actual parameter type
- Fix lowerFunc to use substituteType for param/return types (handles pointers to generic structs)
- Auto-address value receivers when method expects pointer (e.g., b.Get() where self: *Box<T>)
- Add C forward declarations for all functions to fix ordering issues
- Relax type checks for tkTypeParam in assignments and arguments
- Update generics_struct example with Box_Get, Box_Set, Pair_GetFirst/Second

dimgigov 7ee6a73ea4 feat: Std::String, Std::Map, Result/Option, ? operator, sizeof fix, docs
Add standard library modules:
- 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 sizeof() for user-defined structs (new hSizeOf HIR node)
- Fix HIR type lowering for char8, bool8, int8, uint8, etc.
- 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

dimgigov aa3433b5a9 feat: add generics support with monomorphization
- Add ekGenericCall to AST for generic function calls (Max<int>)
- Parse generic type arguments in parsePostfix
- Support generic calls in sema with type parameter substitution
- Implement monomorphization in hir_lower:
  - Collect generic function declarations
  - Find all generic call sites
  - Generate specialized versions with mangled names (Max_int)
  - Substitute type parameters with concrete types
- Add generics.bux example

Example:
  func Max<T>(a: T, b: T) -> T {
      if a > b { return a; }
      else { return b; }
  }

  let m: int = Max<int>(10, 20);  // Generates Max_int
