Brandon Lucas	ce4ab45651	feat: implement evidence passing for O(1) effect handler lookup ... Interpreter changes: - Add evidence HashMap for O(1) handler lookup instead of O(n) stack search - Update eval_run to manage evidence when entering/exiting run blocks - Modify handle_effect to use evidence.get() instead of stack iteration C backend infrastructure: - Add handler structs (LuxConsoleHandler, LuxStateHandler, LuxReaderHandler) - Add LuxEvidence struct containing pointers to all handlers - Add default handlers that delegate to built-in implementations - Add Console.readLine built-in implementation Documentation: - Create docs/EVIDENCE_PASSING.md explaining design and implementation - Update docs/C_BACKEND.md with current progress Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-14 11:52:00 -05:00
Brandon Lucas	909dbf7a97	feat: add list support to C backend and improve compile workflow ... C Backend Lists: - Add LuxList type (dynamic array with void* boxing) - Implement all 16 list operations: length, isEmpty, concat, reverse, range, take, drop, head, tail, get, map, filter, fold, find, any, all - Higher-order operations generate inline loops with closure calls - Fix unique variable names to prevent redefinition errors Compile Command: - `lux compile file.lux` now produces a binary (like rustc, go build) - Add `--emit-c` flag to output C code instead - Binary name derived from source filename (foo.lux -> ./foo) - Clean up temp files after compilation Documentation: - Create docs/C_BACKEND.md with full strategy documentation - Document compilation pipeline, runtime types, limitations - Compare with Koka, Rust, Zig, Go, Nim, OCaml approaches - Outline future roadmap (evidence passing, Perceus RC) - Fix misleading doc comment (remove false Perceus claim) - Update OVERVIEW.md and ROADMAP.md to reflect list completion Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-14 11:02:26 -05:00
