Guard
Guard is a command line tool to easily handle events on file system modifications.
Guard has many very handy features, so read this document through at least once to be aware of them - or you'll likely miss out on really cool ideas and tricks.
Also, by reading through you'll likely avoid common and time-consuming problems which Guard simply can't automatically solve.
If you have any questions about the Guard usage or want to share some information with the Guard community, please go to one of the following places:
- Google+ community
- Google group
- StackOverflow
- IRC channel
#guard
(irc.freenode.net) for chatting
Information on advanced topics like creating your own Guard plugin, programatic use of Guard, hooks and callbacks and more can be found in the Guard wiki.
Before you file an issue, make sure you have read the known issues and file an issue sections that contains some important information.
Features

- Support for visual system notifications.
- Huge eco-system with more than 220 Guard plugins.

Screencast
Two nice screencasts are available to help you get started:
- Guard on RailsCast.
- Guard is Your Best Friend on Net Tuts+.
Installation
The simplest way to install Guard is to use Bundler.
Add Guard (and any other dependencies) to a Gemfile
in your project’s root:
group :development do
gem 'guard'
end
then install it by running Bundler:
$ bundle
Generate an empty Guardfile
with:
$ bundle exec guard init
Run Guard through Bundler with:
$ bundle exec guard
If you are on Mac OS X and have problems with either Guard not reacting to file changes or Pry behaving strange, then you should add proper Readline support to Ruby on Mac OS X.
Avoiding gem/dependency problems
It's important that you always run Guard through Bundler to avoid errors.
If you're getting sick of typing bundle exec
all the time, try one of the following:
(Recommended) Running
bundle binstub guard
will createbin/guard
in your project, which means runningbin/guard
(tab completion will save you a key stroke or two) will have the exact same result asbundle exec guard
Or, for RubyGems >= 2.2.0 (at least, though the more recent the better), simply set the
RUBYGEMS_GEMDEPS
environment variable to-
(for autodetecting the Gemfile in the current or parent directories) or set it to the path of your Gemfile.
(To upgrade RubyGems from RVM, use the rvm rubygems
command).
NOTE: this Rubygems feature is still under development still lacks many features of bundler
- Or, for RubyGems < 2.2.0 check out the Rubygems Bundler.
Add Guard plugins
Guard is now ready to use and you should add some Guard plugins for your specific use. Start exploring the many Guard
plugins available by browsing the Guard organization on GitHub or by searching for guard-
on RubyGems.
When you have found a Guard plugin of your interest, add it to your Gemfile
:
group :development do
gem '<guard-plugin-name>'
end
See the init section of the Guard usage below to see how to install the supplied plugin template that you can install and to suit your needs.
Usage
Guard is run from the command line. Please open your terminal and go to your project work directory.
Look here for a full list of Guard commands
Start
Just launch Guard inside your Ruby or Rails project with:
$ bundle exec guard
Guard will look for a Guardfile
in your current directory. If it does not find one, it will look in your $HOME
directory for a .Guardfile
.
