Examples for Lark — Lark documentation

How to run the examples:

After cloning the repo, open the terminal into the root directory of the project, and run the following:

[lark]$ python -m examples.<name_of_example>

For example, the following will parse all the Python files in the standard library of your local installation:

[lark]$ python -m examples.advanced.python_parser

This example shows how to do grammar composition in Lark, by creating a new file format that allows both CSV and JSON to co-exist.

We show how, by using namespaces, Lark grammars and their transformers can be fully reused - they don’t need to care if their grammar is used directly, or being imported, or who is doing the importing.

See main.py for more details.

sphx_glr_examples_composition_eval_json.py

Transformer for evaluating json.lark

sphx_glr_examples_composition_eval_csv.py

Transformer for evaluating csv.lark

This directory is a collection of lark grammars, taken from real world projects.
