Searching Through Gems

Sometimes you need to peak at the source of a class or method of a gem from your Gemfile. Since gems are managed by bundler, it has a command-line option that can help.

bundle show --paths will list the paths of all the gems from your Gemfile. You can grep through these directories to search.

I'm currently using ripgrep for searching at the command line, so can pass the paths there.

Here’s it all together in a simple Bash function:

function bundle-search() {
    rg $1 `bundle show --paths`
