Setup and Running

This folder contains code related to the core interaction language parser, AST, and execution engine.

Files

• pegs/sql.pegjs is the grammar file for the language. Running pegjs ./pegs/sql.pegjs will generate a javascript parser file as ./pegs/sql.js
• src/sqlast.coffee defines a function that wraps the parser generated from the peg grammar file.
• src/ast.coffee defines the AST nodes for the language. It's a rough subset of SQL and interaction statements.
