lezer-promql
Overview
This is a PromQL grammar for the lezer parser system. It is inspired by the initial grammar coming from Prometheus written in yacc.
This library is stable but doesn't provide any guideline of how to use it as it has been integrated into codemirror-promql. If you want to use this library, you perhaps want to actually use @prometheus-io/codemirror-promql instead.
Note: This library is a lezer-based implementation of the authoritative, goyacc-based PromQL grammar. Any changes to the authoritative grammar need to be reflected in this package as well.
Installation
This package is available as an npm package:
npm install --save @prometheus-io/lezer-promql
Note: you will have to manually install the lezer dependencies as it is a peer dependency to this package.
