Overview

An instance of this class is returned by Rush::Commands#search. It contains both the list of entries which matched the search, as well as the raw line matches. These methods get equivalent functionality to “grep -l” and “grep -h”.

SearchResults mixes in Rush::Commands so that you can chain multiple searches or do file operations on the resulting entries.

Examples:

myproj['**/*.rb'].search(/class/).entries.size
myproj['**/*.rb'].search(/class/).lines.size
myproj['**/*.rb'].search(/class/).copy_to other_dir
