FavLanguage

This is a gem written as a part of a coding challenge. Given a GitHub username it tries to guess the user's favourite programming language.

The criteria used is the amount of bytes written in each language in all public owned repos of the user (omits forked repos).

This gem requires ruby >= 2.1

Add this line to your application's Gemfile:

gem 'fav_language'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fav_language

The gem has a command line interface. If you have the gem installed:

fav_lang -h

Example:

fav_lang -u tadast
> JavaScript: 418357 bytes written

If you have the repo cloned, you can do the above, just append bundle exec exe/ e.g. bundle exec exe/fav_lang -u tadast

require 'fav_language'
fav_stats = FavLanguage::Detector.new(username: 'tadast').favourite_languages
# returns an array of objects that have two properties: weight and language
# it is an array in case the user has two equally favourite languages
fav_stats.size
> 1
fav_stats.first.language
> "JavaScript"
fav_stats.first.weight
> 353577 # bytes commited in this language

GitHub limits the number of requests you can make to the API. To increase this number you may want to get an oauth token. You can follow the instructions on the github_api gem readme to get the token. Then you can pass in the token value via the command line

fav_lang -u tadast -t <token>

or as an argument

fav_stats = FavLanguage::Detector.new(username: 'tadast', token: "<token>")

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.
