资源说明：A simple script that allows you to run Guard to refresh your web browser and optionally recompile Sass/Haml files
# WTF?
In the vein of the [HTML5 Boilerplate](http://html5boilerplate.com) project, this is a simple script that allows you to run [Guard](http://github.com/guard/guard) to refresh your web browser and optionally recompile [Sass](http://sass-lang.com/) files to CSS and/or [Haml](http://haml-lang.com/) files to HTML. Just install it, run`gbp start` in your project directory root and you're off to the races. A Guardfile gets created which you can customize to your tastes.
# tl;dr
Impatient? Have Ruby installed and understand what a gem is? Use the Boilerplates? Rocking Sass and Haml? Great!
1. Install the [LiveReload](https://github.com/mockko/livereload#readme) extension in your browser
2. Install guard_boilerplate and start a new project:
gem install guard_boilerplate
if [ `uname -s` == "Darwin" ] ; then gem install rb-fsevent ; fi
if [ `uname -s` == "Linux" ] ; then gem install rb-inotify ; fi
mkdir my_site && cd my_site
curl -L 'https://github.com/paulirish/html5-boilerplate/tarball/master' | tar -xzf - --strip-components 1
gbp hamlize && gbp sassify
gbp start
3. Hit the LiveReload **LR** button in your browser
4. Edit!
Confused? Read on...
# Before!
## Ruby
You will need to have Ruby already installed on your system, but chances are you do already.
### Mac OS X And Linux (RVM)
If you are on Mac OS X or Linux, then [RVM](http://rvm.beginrescueend.com/) to the rescue:
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
source "$HOME/.rvm/scripts/rvm"
cat <> "$HOME/.bash_profile"
[[ -s "\$HOME/.rvm/scripts/rvm" ]] && . "\$HOME/.rvm/scripts/rvm"
BASHRC
rvm 1.9.2 install && rvm 1.9.2 --default
### Windows (Rails Installer)
This is slighty more than you'll need, but do yourself a favor and use the [Rails Installer](http://railsinstaller.org/) for Windows. It's fast, painless and as a bonus you'll be ready to crank out a [Ruby on Rails](http://rubyonrails.org/) or [Sinatra](http://www.sinatrarb.com/) web application in 5 minutes flat. \[*pause...*\] See, wasn't that easy?
## LiveReload Browser Extension
Secondly, you will need to install the LiveReload browser extension into your browser-du-jour ([Chrome Chrome Chome!](http://google.com/chrome)). For more detailed instructions, see the LiveReload's [github README](https://github.com/mockko/livereload) and look for the extension installation section.
# Install!
Are you ready?
gem install guard_boilerplate
On the Mac?
gem install rb-fsevent
On Linux?
gem install rb-inotify
Now give yourself a slap on the back.
# Use!
## Refresh Automatically
Change directory into your new web-wonder project directory, and start the listener:
cd my_site
gbp start
Using the badass [HTML5 Boilerplate](http://html5boilerplate.com/) as your base? I thought
so. Try this one out, my Mac and Linux pals:
mkdir my_site && cd my_site
curl -L 'https://github.com/paulirish/html5-boilerplate/tarball/master' | tar -xzf - --strip-components 1
gbp start
LiveReload needs to refresh an `http://` URL (rather than a `file://`), so an embedded HTTP server will fire up by default on port 3000 thanks to the [WEBrick guard](https://github.com/fnichol/guard-webrick).
Finally, if you're sitting there with your browser page open, don't forget to activate the LiveReload extension. Otherwise, it's going to get pretty darn boring. Open your `my_site` project in your text editor, update `index.html`, save, and marvel ;)
## Sass Up Your Stylesheets
Would you rather author Sass stylesheets? Migrate your `*.css` files to `*.scss` files automatically:
gbp sassify
Your CSS files will be generated back into `css/` on save. Sweet.
## Haml Your Markup
If Haml is your bag, then you can also convert your `*.html` files to `*.haml` with a quick round of:
gbp hamlize
## Minify Your Haml And SASS Output
To compress your HTML and CSS output (suitable for production):
gbp minify
## Prettify Your Haml And Sass Output
To generate all your HTML and CSS output (suitable for development):
gbp prettify
# Customize!
The file that controls "what happens when" is your `Guardfile` which is pretty straight forward. The `'livereload'` block has a bundle of `watch` listeners that are file patterns. Whenever any of these files change, any attached web browsers will be reloaded with LiveReload.
If your images directory was actually `images/` and could contain gifs, then you could modify the `Guardfile` line from:
watch(%r{img/.+\.(png|jpeg|jpg)})
to:
watch(%r{images/.+\.(gif|png|jpeg|jpg)})
If you need the HTTP server to run on another port, update the `'webrick'` block to:
guard 'webrick', :port => 8080 do
end
Don't worry, your web browser will keep up.
