= OutputCatcher

by Matthias Hennemeyer mhennemeyer@gmail.com

== 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 mhennemeyer-output_catcher
