actrecipemagicfile (A CFFI fork of python-magic)

actrecipemagicfile is a Python interface to the libmagic file type identification library. libmagic identifies file types by checking their headers against a predefined list. This functionality is accessible from the command line using the Unix command file.

Changelog

[2024-12-04]

New: Added support for Mac Silicon (Python 3.10, 3.11).
New: Added support for Linux ARM (Python 3.10, 3.11, 3.12).

Usage

>>> import magicfile as magic
>>> magic.from_file("testdata/test.pdf")
'PDF document, version 1.2'
>>> magic.from_buffer(open("testdata/test.pdf").read(1024))
'PDF document, version 1.2'
>>> magic.from_file("testdata/test.pdf", mime=True)
'application/pdf'

There is also a Magic class that provides more direct control, including overriding the magic database file and turning on character encoding detection. This is not recommended for general use. In particular, it's not safe for sharing across multiple threads and will fail throw if this is attempted.

>>> f = magic.Magic(uncompress=True)
>>> f.from_file('testdata/test.gz')
'ASCII text (gzip compressed data, was "test", last modified: Sat Jun 28
21:32:52 2008, from Unix)'

You can also combine the flag options:

>>> f = magic.Magic(mime=True, uncompress=True)
>>> f.from_file('testdata/test.gz')
'text/plain'
