Claude 39ca246151 Implement NEScript compiler Milestone 1 ("Hello Sprite") ... Complete implementation of the NEScript compiler pipeline for M1: - Lexer: full tokenization with hex/binary/decimal literals, all keywords, operators - Parser: recursive descent with Pratt expression parsing (M1 subset) - Analyzer: symbol resolution, type checking, memory allocation - 6502 Assembler: full opcode encoding table (~150 valid combinations) - Code Generator: AST → 6502 instructions (direct, no IR for M1) - Runtime: NES hardware init, NMI handler, controller read, OAM DMA - Linker: NROM layout, vector table, palette loading, CHR data - ROM Builder: iNES header generation, PRG/CHR padding - CLI: `build` and `check` subcommands via clap 143 tests across all modules: - 22 lexer tests (literals, keywords, operators, error recovery) - 18 parser tests (expressions, statements, game structure, errors) - 7 analyzer tests (symbol resolution, memory allocation, transitions) - 30 assembler tests (every addressing mode, label resolution) - 7 codegen tests (var init, arithmetic, buttons, draw, comparisons) - 11 runtime tests (init sequence, NMI handler, controller read) - 10 ROM builder tests (iNES format, mirroring, banking, validation) - 5 linker tests (vector table, CHR data, palette loading) - 7 integration tests (end-to-end compilation, error detection) CI: GitHub Actions for check, fmt, clippy, test Pre-commit: script for local fmt + clippy + test validation https://claude.ai/code/session_01W6eQFStA66EuMKHUFo2rx3		2026-04-11 22:07:56 +00:00
