== DESCRIPTION:

"Harsh: Another Rails Syntax Highlighter," is just that - it highlights code
in Rails, much like Radiograph or tm_syntax_highlighting. However, it does it well, _better_.
Oh, and it also supports Haml, as well as ERb. And it comes with rake tasks.

Firstly, it allows block form:
<% harsh :theme => :dawn do %>
class Testing
def initialize(str)
puts str
end
end
<% end %>
as well as the form the other plugins offer, which is text as a parameter:
<% harsh %Q{
class Testing
def initialize(str)
puts str
end
end
}, :theme => :dawn

For haml, harsh is implemented as a filter. First, add this to the bottom of your environment.rb:
Harsh.enable_haml

Then, to use harsh in Haml:
:harsh
class Foo < Bar
end

However, haml's filters can't take options. So how on earth are we going to customize it to our
heart's delight? Easily, my friend, fret not! Enter the BCL (Bootleg Configuration Line):

:harsh
#!harsh theme = all_hallows_eve lines=true syntax=css
h1 {
float:left;
clear:left;
position:relative;
}

It has to be the first line in the filter. You don't need the config line, though. Also, notice
that you can have spaces between the arguments and the little = sign.

Harsh also offers rake tasks for what tm_syntax_highlighting provides in generators,
and a :harsh as a stylesheet-includer to load all syntax-highlighting files, as such:
<%= stylesheet_include_tag :harsh %>

The rake tasks for setting up your stylesheets are these:
rake harsh:theme:list # lists available themes
rake harsh:theme:install[twilight] # installs the twilight theme into /public/stylesheets/harsh/
rake harsh:theme:install THEME=twilight # also installs the twilight theme (for *csh shells)
rake harsh:theme:uninstall[twilight] # removes the twilight theme
rake harsh:theme:uninstall THEME=twilight # also uninstalls the twilight theme (for *csh shells)

While purely informative, you can find out the available syntaxes as follows:
rake harsh:syntax:list

== FEATURES/PROBLEMS

* Syntax highlighting with text as a parameter AND block form!
* Rake tasks for setting up your stylesheets!
* Free hat!

== SYNOPSIS

You can pass any of these parameters to tweak things:
<% harsh :theme => :dawn, :lines => true, :format => :css do %>
h1 {
float:left;
clear:left;
position:relative;
}
<% end %>

In its default form though, harsh will use the twilight theme, no lines, and
will expect Ruby code.

<% harsh %Q{
class Testing
def initialize(str)
puts str
end
end
}, :theme => :dawn

For Haml:

:harsh
#!harsh theme = all_hallows_eve lines=true syntax=css
h1 {
float:left;
clear:left;
position:relative;
}

The #!harsh line is a configuration line that is optional. Notice that the parameter is "syntax=css",
not "format" as is the case with the ERb helper.

== REQUIREMENTS

* oniguruma - a regex library. See installation.
* ultraviolet gem - this does the highlighting. See installation.
* haml - if you want to use the haml filter. duh.

== INSTALL

First, you'll need oniguruma - a regex library. If you don't think you have this, you probably don't.
To install it, do the following:
wget http://www.geocities.jp/kosako3/oniguruma/archive/onig-5.8.0.tar.gz
tar zxvf onig-5.8.0.tar.gz
cd onig-5.8.0/
./configure && make && sudo make install

ultraviolet gem - do this AFTER oniguruma!
sudo gem install ultraviolet

Then, install this plugin:
script/plugin install git://github.com/michaeledgar/harsh.git
