Grammar Design Skill

Overview

Expert skill for formal grammar design including disambiguation, precedence, and validation.

Capabilities

Write EBNF/BNF grammar specifications
Design unambiguous grammars
Handle operator precedence and associativity
Analyze grammar conflicts
Design grammar for specific parser classes (LL, LR, PEG)
Document grammar with examples
Design syntax for common language constructs
Handle grammar evolution and backwards compatibility

Target Processes

language-grammar-design.js
lexer-implementation.js
parser-development.js

Dependencies

Parsing theory literature (Dragon Book, Parsing Techniques)

Usage Guidelines

Notation: Use standard EBNF notation for grammar specifications
Disambiguation: Make grammars unambiguous or document precedence rules
Parser Class: Design grammar to fit target parser class (LL(k), LALR, PEG)
Examples: Include examples for all grammar rules
Evolution: Plan for backwards-compatible grammar evolution
