@microsoft/powerquery-parser
Advanced tools
A parser for the Power Query/M language, written in TypeScript. Designed to be consumed by other projects.
The most common way to consume the project is to interact with the helper functions found in taskUtils.ts. There are all-in-one functions, such as tryLexParse, which does a full pass on a given document. There are also incremental functions, such as tryLex and tryParse, which perform one step at a time. Minimal code samples can be found in example.ts.
The parser started off as a naive recursive descent parser with limited backtracking. It mostly followed the official specification released in October 2016. Deviations from the specification should be marked down in specification.md. A combinatorial parser has since been added which uses the naive parser as its base.
This project uses prettier as the primary source of style enforcement. Additional style requirements are located in style.md.
