Raw Blame History

I have a penchant for setting up all my projects so they work the same.

I like to do these things in all my projects:

Have all my tests run before committing. I don't like buying ice cream for the team on test failures.
If I'm developing gems alongside this project, I use a Gemfile.erb to get around the "one gem, one source" issue in current versions of Bundler.
If I'm moving to different machines or (heaven forbid!) having other developers work on the project, I want to make getting all those local gems as easy as possible.

This gem makes that easier!

What's it do?

Installs a bunch of scripts into the scripts directory of your project:

gemfile which switches between Gemfile.erb environments
install-git-hooks which will do just what it says
hooks/pre-commit, one of the hooks the prior script installs
initialize-environment, which bootstraps your locak environment so you can get up and running

Gemfile.erb?!

Yeah, it's a Gemfile with ERB in it:

<% if env == "local" %>
  gem 'guard', :path => '../guard'
<% else %>
  gem 'guard', :git => 'git://github.com/johnbintz/guard.git'
<% end %>

Use script/gemfile local to get at the local ones, and script/gemfile remote (or anything, really) to get at the remote ones. It then runs bundle install.

git hook?!

It runs script/gemfile remote then runs bundle exec rake. Make sure your default Rake task for the project runs your tests and performs any other magic necessary before each commit.

How?!

gem install penchant
cd to your project directory
penchant install (can do --dir=WHEREVER, too)
