OutputCatcher

by Matthias Hennemeyer <[email protected]>

Introduction

OutputCatcher is available as a Rails plugin and as a gem. It provides a way to capture the standard out($stdout) or standard error($stderr) of your code without pain and suppresses the output of the ‘err’ or ‘out’ stream.

Usage

OutputCatcher knows only two methods: .catch_err and .catch_out

To capture the stderr of your code:

err = OutputCatcher.catch_err do
  $stderr << "error error"
end
err #=> "error error"

To capture the stdout of your code:

out = OutputCatcher.catch_out do
  puts "Hello Hello"
end
out #=> "Hello Hello"

INSTALL:

Rails:

$ ruby script/plugin install git://github.com/mhennemeyer/output_catcher.git

Gem:

$ gem install output_catcher --source=http://gems.github.com
