Ultra-lightweight pure Python package to check if a file is binary or text.

Project Description

Ultra-lightweight pure Python package to guess whether a file is binary or text, using a heuristic similar to Perl’s pp_fttext and its analysis by @eliben.

Status

It works, and I’m using this package in various places. But it doesn’t cover all edge cases yet.

The code could be improved. Pull requests welcome! As of now, it is based on these snippets, but that may change:

Features

Has tests for these file types:

  • Text: .css, .json, .txt, .svg
  • Binary: .eot, .otf, ttf, .woff, .png, .jpg, .tiff, .bmp

Why?

You may be thinking, “I can write this in 2 lines of code?!”

It’s actually not that easy. Here’s a great article about how perldoc’s heuristic to guess file types works: http://eli.thegreenplace.net/2011/10/19/perls-guess-if-file-is-text-or-binary-implemented-in-python/

Also, this package saves you from having to write and thoroughly test those 2 lines of code with all sorts of weird file types, cross-platform.
