feat(mongodb): add MongoDB Shell (mongosh) parser#50
Merged
Conversation
Add ANTLR grammar for parsing MongoDB shell syntax with Go code generation. Supported features: - Shell commands: show dbs, show databases, show collections - Database statements: db.collection.method(...) with method chains - Collection access: dot notation, bracket notation, getCollection() - Read methods: find(), findOne() - Cursor modifiers: sort(), limit(), skip(), projection(), project() - Helper functions as distinct AST nodes: ObjectId(), ISODate(), Date(), UUID(), Long(), NumberLong(), Int32(), NumberInt(), Double(), Decimal128(), NumberDecimal(), Timestamp(), RegExp() - Document syntax: unquoted/quoted keys, nested documents, arrays, trailing commas - Regex literals: /pattern/flags - Literals: strings (single/double quoted), numbers, booleans, null - Comments: line (//) and block (/* */) The 'new' keyword is intentionally not supported for helper functions. When users write 'new ObjectId()', the parser generates a helpful error message using ANTLR's NotifyErrorListeners mechanism. Also adds mongodb to the CI workflow parser list. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
