function-parser 0.0.4

This library contains various utils to parse GitHub repositories into function definition and docstring pairs. It is based on tree-sitter to parse code into ASTs and apply heuristics to parse metadata in more details. Currently, it supports 6 languages: Python, Java, Go, Php, Ruby, and Javascript. It also parses function calls and links them with their definitions for Python.

Install

pip install function-parser

How to use

In order to use the library you must download and build the language grammars for tree-sitter to parser source code with. Included in the library is a handy CLI tool for setting this up.

To download and build grammars: build_grammars

This command will download and build the grammars in the same location this python library was installed on your computer after pip installing.
