Examples for Lark¶
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.
main.py](main.py) for more details.
# Example Grammars
