Simple command-line wrapper of Ruby-based Github Linguist. Linguist (and hence this Python wrapper) detect the language of a Git repo, based on the commited files .gitattributes is used to configure Linguist to not get distracted by docs or archive files, etc. using several straightforward rules.

1. Install Linguist as usual:

   gem install github-linguist

2. Install Python wrapper:

   pip install -e .

From Terminal:

ghlinguist

Or import as a Python module.

import ghlinguist as ghl

langs = ghl.linguist('~/mypath')

The functions return a list of tuples like:

[('Python'), (97.)]
[('Fortran'), (3.)]

where the second number is the percentage of code detected for that language.

If the directory is not a Git repo, None is returned

The primary reason behind creating this Python Linguist wrapper is automatically detecting the repo type, so that appropriate templates can be applied en masse to a large number of repos. Thus to get the repo language from the command line, as GitHub would:

ghlinguist -t

or as a Python module:

import ghlinguist as ghl

lang = ghl.linguist('~/mypath', rpath=True)

Both cases simply return the string Python or Fortran etc.

ghLinguist parses text output from GitHub Linguist, which is a Ruby program.

If you don't already have RubyGems setup on Linux:

1. setup RubyGems:

   apt install ruby-dev libssl-dev libicu-dev zlib1g-dev libcurl4-openssl-dev
   
   gem update --system

2. be sure Gems are installed to home directory, NOT system (no sudo) by adding to ~/.bashrc:

   # Install Ruby Gems to ~/gems
   export GEM_HOME=$HOME/gems
   export PATH=$HOME/gems/bin:$PATH
