Claude	24db4e6cda	CI: add emulator smoke test job ... Runs the jsnes + puppeteer harness on every push/PR so the same execution-level bugs that the test suite previously couldn't catch (missing JMP/JSR fixups, orphaned handler locals, uninitialized struct fields, silently-swallowed intrinsic calls) will be caught in CI going forward. The job installs the handful of shared libs Chrome for Testing needs on the ubuntu-latest runner, builds the compiler in release, compiles every example, then drives each ROM through the harness. On failure it uploads the captured screenshots and the JSON report as a build artifact so regressions are easy to triage without re-running locally. Kept separate from the existing `Build Examples` job so compile-time and execution-time issues report independently. https://claude.ai/code/session_014Z5y3Q9krLcAxYpZQJhZ5V	2026-04-12 18:49:36 +00:00
Claude	fd5a940c89	Add example builds to CI, document sprite name behavior ... - CI: new "Build Examples" job compiles all .ne files and validates the output ROMs have correct iNES headers - Examples: add notes explaining that sprite names (Smiley, Ball) are parsed but not yet resolved — all draws use the built-in CHR tile 0. Custom sprite declarations come in M3. - Codegen: explicit `let _ = &draw.sprite_name` to document the intentional skip, with comment about M2/M3 scope https://claude.ai/code/session_01W6eQFStA66EuMKHUFo2rx3	2026-04-11 22:55:43 +00:00
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
