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.

Features

The Language Server currently supports

• GotoDefinition
• Hover
• Document symbols
• Renaming non-terminal symbols (except the start symbol)
• Formatting the source configurable via format settings
• 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.

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