Description
Enhances search command by displaying results in an ascii table and providing options to search (–fields) and display (–columns) gemspec attributes. These options take any gemspec attribute and more than one when comma delimited. Gemspec attributes can be aliased by specifying the first unique string that it starts with i.e. “su” for “summary”.
Install
Install the gem with:
sudo gem install gem_grep
Examples
If you want to choose what gemspec attributes (columns) you see in your results, no problem. Pass a comma delimited list to –columns/-c in the order you want to see them. For any gemspec attribute, you can pass its alias which is the first unique string that it starts with.
# n,ho,da are shortcuts for name,homepage,date
bash> gem grep -c n,ho,da irb

Choosing your columns works for remote gems as well.

For local gems only, you get increased searching ability with –fields/-f. Pass it a comma delimited list of gemspec attributes you want to search on, aliased as shown above. Let’s see my gems that were created/authored by jamis:

Like the default search and query commands, grep converts your search term to a regular expression. Let’s use this to find out my gems that were created from 2000-2005. Hopefully not too many.
