gem-grep

by Lin Jen-Shin (godfat)

• github
• rubygems

grep the gem for a given name or grep the file for a given require path.

Also checkout gem-eit.

• Tested with MRI (official CRuby) and JRuby.
• gem-path
• grep from shell, or set $GEM_GREP to ag (The Silver Searcher), rg (ripgrep) or other compatible command.
• rg is recommended.

gem install gem-grep

Please set $GEM_GREP to the command you want to search sources. By default it would pick grep if nothing is set. However we recommend rg if you have it installed.

Use -- to pass arguments to $GEM_GREP, such as --color, -E, or -A.

Also checkout gem.fish for fish completion.
