> programming-languages

File extensions for programming languages.

It's just a JSON file, so you can use it in any environment. Sourced from GitHub's Linguist project (defines all 500+ programming languages known to GitHub). Data is updated via script and released via new package version.

Installation

pip install programming-languages

Usage

import programming_languages

py_lang_data = programming_languages['Python']

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

Note: Most type checkers will falsely warn programming_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 language from an extension:

def get_lang(file_ext):
    for lang, data in programming_languages.items():
        if file_ext in data['extensions']:
            return lang

print(get_lang('.al')) # => AL

Get language from a file path:

def get_lang_from_path(filepath):
    from pathlib import Path
    file_ext = Path(filepath).suffix
    for lang, data in programming_languages.items():
        if file_ext in data['extensions']:
            return lang

print(get_lang_from_path('main.rs')) # => Rust
print(get_lang_from_path('script.kt')) # => Kotlin
print(get_lang_from_path('data.avsc')) # => None (use data-languages pkg)
