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.
- 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
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
New examples: strings, map, result_option, try_operator (13 total)
- Parse range expressions in expressions (0..5, 0..=5)
- Add ekRange AST node, hRange HIR node
- Lower for-range to while loop with alloca counter
- Add hBlock.isScope flag for C scope emission
- Update C backend to emit scope blocks only when isScope is set
- Parse module paths in stdlib (module Std::Array { ... })
- Collect stdlib declarations and inject into user modules before sema
- Add dkExternFunc support throughout pipeline (parser, sema, hir, c backend)
- Auto-dereference pointer types for field access (arr->field)
- Add hArrowField HIR node for cleaner C emission
- Fix resolveTypeExpr for pointer and cast types
- Fix struct field lowering to use resolveTypeExpr
- Allow int <-> uint implicit conversion for bootstrap convenience
- Add stdlib/Std/Array.bux with dynamic array primitives
- Add stdlib_test demonstrating Array usage via import Std::Array::{Array};
- C backend: strip c8/c16/c32 string prefixes in emitted C
- C backend: resolve imports to fully-qualified names (Std_Io_PrintLine)
- Parser: fix infinite loop on < in comparisons vs generic calls
- Parser: fix enum patterns without parens (Option::None)
- Parser: fix match expressions inside blocks
- Sema: extract pattern bindings for match arms
- HIR: lower match expressions to if-else chains with enum tag checks
- HIR/C backend: support block expressions as function return values
- Makefile: add integration tests for all 9 examples
- Add pattern_matching.bux example
- Generate tagged unions in C backend for enums with data
- Add HirEnumVariant type with fields and namedFields
- Support _Tag and _Data field access in sema
- Support enum variant constants (Result_Ok, Result_Err)
- Support _Data union field access (Ok_0, Err_0, etc.)
- Add algebraic_enums.bux example
Example:
enum Result {
Ok(int),
Err(String)
}
let r: Result = Result { tag: Result_Ok };
r.data.Ok_0 = 42;
- Map tkAssign to '=' in operatorToC
- Add tkAmpAssign, tkPipeAssign, tkCaretAssign, tkShlAssign, tkShrAssign
- Fibonacci program now works correctly with while loops and assignment
- Add stdlib/io.c with PrintLine, Print, PrintInt, PrintFloat, PrintBool, ReadLine
- Support extern function declarations (functions without body)
- Generate C forward declarations for extern functions
- Map Bux type names (String, int, etc.) to C types in codegen
- Update build system to copy all stdlib files
- Hello World example works: prints 'Hello, Bux!'
