CODE_GENERATION_COMPLETE
Encoding::Emacs Code Generation - Complete! ā
Summary
Successfully implemented Phase 2: Code Generation for the Encoding::Emacs project.
What Was Built
1. Parser Module (lib/Encoding/Emacs/Parser.rakumod)
Full Raku Grammar for parsing Emacs charset definitions
Support for
define-charset,define-iso-single-byte-charset, anddefine-charset-aliasExtracts all properties: strings, numbers, chars, vectors, booleans
Returns structured CharsetDef and AliasDef objects
2. Generator Module (lib/Encoding/Emacs/Generator.rakumod)
Generates idiomatic Raku encoding classes
Name normalization (iso-8859-1 ā Iso_8859_1)
Creates alias classes with inheritance
Generates registry module for bulk registration
Clean, readable code output
3. Command-Line Generator (bin/generate-encodings.raku)
Reads Emacs mule-conf.el files
Generates entire encoding library in one command
Progress reporting and statistics
4. Test Suite (t/*.rakutest)
Parser tests: 7 passing
Generator tests: 5 passing
Total: 12 passing tests
Results
From the full Emacs mule-conf.el file:
80 total files generated
56 charset classes (ISO-8859, Windows, DOS, KOI8, etc.)
24 alias classes (cp1252 ā windows-1252, etc.)
1 registry module
All generated code compiles successfully!
Next Steps
Phase 3 will add:
Mapping table integration from Emacs
Actual decoder/encoder implementation
Round-trip encoding tests
Performance optimization
The foundation is solid and the code generation pipeline is fully automated!
