[ [**WEBSITE**](http://lezer.codemirror.net) | [**ISSUES**](https://github.com/lezer-parser/lezer/issues) | [**FORUM**](https://discuss.codemirror.net/c/lezer) | [**CHANGELOG**](https://github.com/lezer-parser/lr/blob/master/CHANGELOG.md) ] | |
Lezer ("reader" in Dutch, pronounced pretty much as laser) is an | |
incremental GLR parser intended for use in an editor or similar | |
system, which needs to keep a representation of the program current | |
during changes and in the face of syntax errors. | |
It prioritizes speed and compactness (both of parser table files and | |
of syntax tree) over having a highly usable parse tree—trees nodes are | |
just blobs with a start, end, tag, and set of child nodes, with no | |
further labeling of child nodes or extra metadata. | |
This package contains the run-time LR parser library. It consumes | |
parsers generated by | |
[@lezer/generator](https://github.com/lezer-parser/generator). | |
The parser programming interface is documented on [the | |
website](https://lezer.codemirror.net/docs/ref/#lr). | |
The code is licensed under an MIT license. | |
This project was hugely inspired by | |
[tree-sitter](http://tree-sitter.github.io/tree-sitter/). | |
