parcel-transformer-lezer

A Parcel transformer for @lezer/generator.

Usage:

Install this package and some Lezer packages that will be imported by the generated code

yarn add -D @parcel/config-default parcel-transformer-lezer
yarn add @lezer/common @lezer/lr

Add a .parcelrc with

{
    "extends": "@parcel/config-default",
    "transformers": {
        "*.grammar": ["parcel-transformer-lezer"]
    }
}

Then import it from Javascript.

import { parser } from "./foo.grammar";

let tree = parser.parse("...");

parser is an instance of LRParser. Apart from this method, there is also an export for each grammar term mapping to its id.

See the example folder for a complete example.

You can put this somewhere to make Typescript happy:

declare module "*.grammar" {
  import type { LRParser } from "@lezer/lr";
  export const parser: LRParser;
}
