A simple gem for easily capturing writes to STDOUT & STDERR
I needed to write this for testing calls to #puts in an app and it took me awhile to get the code working properly (especially without having to write to the filesystem to get the output properly).
I figured that I might need this again or someone else might find this handy so … here it is!
$ gem sources -a http://gems.github.com $ sudo gem install remi-capture
>> Capture { puts 'hello' }
=> 'hello'
>> Capture(:stdout){ puts 'hello stdout' }
=> 'hello stdout'
>> Capture(:stderr){ warn 'hello stderr' }
=> 'hello stderr'
That’s it! Like I said, super simple.
If I get bored, I’d like to update this to be able to capture writes to any IO object. That could be super useful!
