parol-ls README


This project provides a Language Server to support parol's syntax of grammar description files (.par files).

It is used for instance by Parol's VSCode extension

This Language Server is developed with the help of parol itself.


The Language Server currently supports

  • GotoDefinition
  • Hover
  • and shows syntax errors as you are used to.

Also problems in your grammar are detected and reported.

This tool is still in early development phase. But it can be used in conjunction with Parol's VSCode extension.


Please install this language server on your platform using the following command.

cargo install parol-ls

Also check regularly for updates and issue the command above again on demand.
