💻 computer-languages

File extensions for computer languages.

It's just a JSON file, so you can use it in any environment. Sourced from GitHub's Linguist project (defines all 700+ languages known to GitHub). Data is updated via script and released via new package version.

Installation

pip install computer-languages

Usage

import computer_languages

py_lang_data = computer_languages['Python']

print(py_lang_data['type']) # => programming
print(py_lang_data['extensions']) # => ['.cgi', '.fcgi', '.gyp', ...]

Note: Most type checkers will falsely warn computer_languages is not subscriptable because they are incapable of analyzing runtime behavior (where the module is replaced w/ a dictionary for cleaner, direct access). You can safely suppress such warnings using # type: ignore.

Examples

Get extension(s) for a language:

js_exts = computer_languages['JavaScript']['extensions']

print(js_exts) # => ['._js', '.bones', '.cjs', '.es', ...]

Get language(s) from an extension:

def get_lang(file_ext):
    lang_matches = [
        lang for lang, data in computer_languages.items()
            if file_ext in data['extensions']
    ]
    return lang_matches[0] if len(lang_matches) == 1 else lang_matches

print(get_lang('.rs')) # => ['RenderScript', 'Rust', 'XML']

Filter by language type:

markup_langs = [
    lang for lang, data in computer_languages.items()
        if data['type'] == 'markup'
]

print(markup_langs) # => ['Antlers', 'API Blueprint', 'Astro', 'BibTeX', ...]
print(f'{len(markup_langs)} markup languages') # -> 69 markup languages
