This package is deprecated. It has been fully migrated to the repository prometheus/prometheus, and it is published under the npm organization @prometheus-io.

See the corresponding readme for further information.

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 codemirror-promql instead.

Note: This library is following the changes of the upstream grammar (i.e. coming from Prometheus) as closed as possible

This package is available as a npm package:

npm install --save lezer-promql

Note: you will have to manually install the dependency lezer as it is a peer dependency to this package.

npm install --save lezer

npm i
npm run build

npm run test
