This project establishes the central development and maintenance of syntax definition files for the PowerShell language used by editors that leverage the XML version of the TextMate language grammar format.

Currently this syntax definition is used by GitHub and by the following editors and extensions:

In the future we may find a more common syntax that allows us to generate syntax definitions for editors that don't leverage the TextMate format.

This branch includes fixes and improvements to the syntax grammar as well as new tooling for unit tests. See the overview in WHATS_NEW.md.

• Node.JS - tested on the current LTS (26.x at the time of writing) but may work on other versions.

PS> npm install

PS> npm run full

PS> npm run build

PS> npm run test

PS> npx textmate-grammar-test testfiles/operators/format.ps1

We would love to have community contributions to this project to make PowerShell syntax highlighting great in as many editors as we can. Please feel free to file issues or send pull requests if you'd like to contribute.
