RubyGems Automatic Ctags Invoker
Nary a day of Ruby development goes by where I don't run
gem open or
bundle open. And when I go rooting around
in a gem, I want tags. As good as I've gotten at
ctags -R ., I've
grown weary of it. So I wrote a RubyGems plugin to automatically invoke
Ctags on gems as they are installed.
If you haven't already, install Exuberant Ctags and make sure it
comes first in
$PATH. With Homebrew,
brew install ctags. Now all
that's left to do is install gem-ctags and perform a one-off indexing of
the gems that are already installed:
gem install gem-ctags gem ctags
If you're using RVM, I recommend extending your global gemset by adding
~/.rvm/gemsets/global.gems. Put it at the top so the
gems below it will be indexed.
To easily edit a gem with your current working directory set to the gem's root, install gem-browse.
If you have rake.vim installed (which, by the way, is a misleading name), Vim will already know where to look for the tags file when editing a gem.
If you have bundler.vim installed, Vim will be aware of all tags files from all gems in your bundle.
If you want to get crazy, add this to your vimrc to get Vim to search all gems in your current RVM gemset (requires pathogen.vim):
autocmd FileType ruby let &l:tags = pathogen#legacyjoin(pathogen#uniq( \ pathogen#split(&tags) + \ map(split($GEM_PATH,':'),'v:val."/gems/*/tags"')))
I don't like to get crazy.
Don't submit a pull request with an ugly commit message or I will ignore your patch until I have the energy to politely explain my zero tolerance policy.
