Fast Trees

Cute little python module that sits atop the tree-sitter library to provide an easier to use and cleaner interface for interacting with source code

Install

fast-trees requires git to be installed on your system for downloading the different tree-sitter languages. So, make sure it is installed before using fast-trees. See here for instruction on installing git.

To install fast-trees, simply run:

pip install fast-trees

How to use

Easily work with source code data by using the high level API. Here's how you can grab the parameters of a java method:

mthd = """public static void main(String[] args, Object clazz) {
    // This is a test
    System.out.println(args[0]);
    /**
        This is another test!
    */
}
"""
parser = FastParser("java")
print(parser.get_method_parameters(mthd))

['args', 'clazz']

And here is how you can grab all of the inline comments:

inline_comments = parser.get_method_inline_comments(mthd)
for c in inline_comments:
    print(c)

// This is a test
/**
        This is another test!
    */

Supported Languages

• Java

TODO

• Add ability to grab method parameters
• Add separation between parsing methods vs classes
• Add ability to get all methods in a class
• add ability to get all instance variables in a class
• Add more languages
