README.md
MimeMagic is a library to detect the mime type of a file by extension or by content. It uses the mime database
provided by freedesktop.org (see http://freedesktop.org/wiki/Software/shared-mime-info/).
Dependencies
You will require a copy of the Freedesktop.org shared-mime-info database to be available. If you're on Linux,
it's probably available via your package manager, and will probably be in the location it's being looked for
when the gem is installed.
macOS users can install the database via Homebrew with brew install shared-mime-info.
Should you be unable to use a package manager you can obtain a copy of the needed file by extracting it from
the Debian package. This process will also work on a Windows machine.
- Download the package from https://packages.debian.org/sid/amd64/shared-mime-info/download
- Ensure the command line version of 7-Zip is installed
7z x -so shared-mime-info_2.0-1_amd64.deb data.tar | 7z e -sidata.tar "./usr/share/mime/packages/freedesktop.org.xml"
Place the file freedesktop.org.xml in an appropriate location, and then set the environment variable
FREEDESKTOP_MIME_TYPES_PATH to that path. Once that has been done the gem should install successfully. Please
note that the gem will depend upon the file remaining in that location at run time.
Usage
require 'mimemagic'
MimeMagic.by_extension('html').text?
MimeMagic.by_extension('.html').child_of? 'text/plain'
MimeMagic.by_path('filename.txt')
MimeMagic.by_magic(File.open('test.html'))
# etc...
You can add your own magic with MimeMagic.add.
