Go bindings for libmagic

There are number of existing bindings for libmagic, for example github.com/vimeo/go-magic.

This binding aims to be self contained, without requiring libmagic to be installed. This allows us to build this dependency for all architectures even Windows.

Installing

go get https://github.com/Velocidex/go-magic

This package contains libmagic source code already so you do not need to have it installed on the system.

How to use it from Go code.

The first step is to obtain a handle to the library.

handle := magic.NewMagicHandle(magic.MAGIC_NONE)
defer handle.Close()

// Load built in magic files
magic_files.LoadDefaultMagic(handle)
classification := handle.File("foobar.jpeg")

This binding bundles the built in magic files. You can load them into memory by calling magic_files.LoadDefaultMagic(handle).

The packages magic files are the default ones provided by the file package.
