5Lezer ("reader" in Dutch, pronounced pretty much as laser) is an
6incremental GLR parser intended for use in an editor or similar
7system, which needs to keep a representation of the program current
8during changes and in the face of syntax errors.
9
10It prioritizes speed and compactness (both of parser table files and
11of syntax tree) over having a highly usable parse tree—trees nodes are
12just blobs with a start, end, tag, and set of child nodes, with no
13further labeling of child nodes or extra metadata.

15This package contains the run-time LR parser library. It consumes
16parsers generated by
17[@lezer/generator](https://github.com/lezer-parser/generator).
18
19The parser programming interface is documented on [the
20website](https://lezer.codemirror.net/docs/ref/#lr).
