Chevrotain

Multiple Start Rules

Chevrotain supports using any of the grammar rules as a starting rule. This means that any subset of a language can be parsed without being wrapped in other constructs, For example this can be used for:

  • Implementing "debugger watch expressions" and "evaluate expression" in an IDE.
  • Parsing only modified text in an IDE for performance.
  • Easy unit testing for small language snippets.
