Programmatically determine gem's path using bundler

Question

I know you can do

bundle show gem_name

to show the path of some gem.

How do you do that from within the code using the Bundler object?<

Answer 1

Yup, cli.rb is the best way to look at. However you anyway have to find a spec's name.

I can give you a starting point, but you have to come with some solution on how to optimize to your case:

    GemSearcher = Gem::GemPathSearcher.new
    Init = GemSearcher.init_gemspecs()
    GemSearcher.lib_dirs_for(Init[0])

Unfortunately this solution provides nameless search as all Gems are in an array instead of hash, but if you want you can hack GemPathSearcher, I think that would be useful in the future.
