A modern gem manager.
Gel is a lightweight alternative to Bundler.
|Gel||Bundler & Rubygems|
This gem is still a work in progress, and things that are still needing some additional improvements include Documentation, UI & Error Messages, and Platform compatibility. We are open to and appreciate any help improving any of these areas.
Why Should I Use Gel?
Gel was written with the goal of improving the performance of common Bundler tasks. Eventually we would like to backport known performance improvements back into Bundler so that everyone can benefit from these improvements, but it is easier to implement and test potential performance improvements in a smaller, more lightweight codebase beforehand.
Another way that Gel gains a performance benefit over Bundler is simply that Gel includes less features overall. For anyone that doesn't need all the features provided by Bundler, using Gel as a more lightweight gem manager might be beneficial.
One of the improvements that Gel has over Bundler is being able to take advantage of a new version solver called Pub Grub. Gel utilizes the
pub_grub gem (https://github.com/jhawthorn/pub_grub) which is a Ruby port of the PubGrub algorithm.
Some real world examples of the types of performance improvements Gel provides over Bundler are as follows:
% gel exec rake -version: 55% faster than
% gel exec rails --version: 60% faster than
% gel exec rails runner nil: 45% faster than
Comparing using a complex, mature Rails application:
% gel install: 55% faster than
% gel lock: 78% faster than
bundleon first run
% gel lock: 95% faster than
bundleon later runs (cache exists)
Comparing using a simple Gemfile with a complex gem:
source "https://rubygems.org" gem "tty"
% gel install: 70% faster than
% gel lock: 34% faster than
Comparing using an example Gemfile with gems that showcase a difficult version resolving:
source "https://rubygems.org" gem "activerecord" gem "quiet_assets"
% gel lock: 96% faster than
This example showcases the speed improvements provided by the new PubGrub Version Solving algorithm.
Note that all of the performance numbers were gathered using just a regular laptop used for common day-to-day development. These numbers were not measured in perfect isolation and your experience may vary.
If you're on a Mac, we recommend that you install via Homebrew:
$ brew install gel
Otherwise, you can install Gel as a gem:
$ gem install gel
Then, either activate Gel in your current shell:
$ eval "$(gel shell-setup)"
Or add it to your
.zshrc to enable it everywhere:
$ echo 'eval "$(gel shell-setup)"' >> ~/.bashrc
gel update, and
gel exec as you would the equivalent
GEL_GEMFILEThe path to the gemfile gel should use
GEL_LOCKFILEThe path to the lockfile that gel should use
GEL_CACHEThe path to the gel version information cache
After checking out the repo, run
bin/setup to install dependencies. Then, run
bin/rake test to run the tests.
To use your development instance as your primary Gel, add its
exe/ to your
$PATH before running
shell-setup, ensuring it comes before any RubyGems
bin directory that might override it.
PATH="$HOME/projects/gel/exe:$PATH" eval "$(gel shell-setup)"
