代码语法高亮

rhighlightjs

官网：

http://softwaremaniacs.org/soft/highlight/en/

使用起来比较简单

enviroment.rb
  config.gem 'romanvbabenko-rhighlightjs', :lib => 'rhighlightjs',
      :source => 'http://gems.github.com'

sudo rake gems:install

#your.view
= highlighter :style => 'sunburst', :languages => ["css", "html-xml", "django", "rubyscript", "www"]

html的显示和整理

html tidy
也很简单

tidy介绍
http://www.w3.org/People/Raggett/tidy/

 config.gem "tidy"

    Tidy.path = '/usr/lib/libtidy.A.dylib'
    curl = Monitoring::Index.find(params[:id]).url
    @source = Nokogiri::HTML(open(curl)).to_html#.gsub(/\s{4,}/,'')
    charset = @source[/meta http-equiv=".+content=".+charset=[^"]+/].split("=").last rescue "utf8"
    @source = Iconv.new('UTF-8', charset).iconv(@source) unless charset == "utf8"
    opts = {
      #:output_xhtml  => true,
      :wrap          => 0,
      :char_encoding => charset,
      :show_warnings => true,
      #:show_body_only => true,
      #:doctype => 'omit',
      :indent        => true, # optional 
    }
    Tidy.open(opts) do |tidy|
       @source = tidy.clean(@source) 
       #puts tidy.errors # array
       #puts tidy.diagnostics # array
       #puts xml
     end

Tidy Ruby Gem
Tidy: http://tidy.sourceforge.net/
Tidy-Ruby: http://rubyforge.org/projects/tidy/

If you're experiencing a Segmentation Fault (Rails app could not start)
see http://github.com/FireRabbit/tidy/tree

List of Tidy-Ruby Options
===========================================
See http://tidy.sourceforge.net/docs/quickref.html

libtidy is the backend of this gem.
Just replace hyphens with underscores.

For example,
   show-warnings will be show_warnings
   show-body-only will be show_body_only
   etc

Installation
===========================================
# Do not use gem install tidy. It is outdated and buggy
# if you've done so already, do gem uninstall tidy and
# follow the directions below

$ git clone git://github.com/FireRabbit/tidy.git
$ cd tidy/
$ sudo ruby setup.rb

＃Rails app? make Tidy a dependency environment.rb
＃===========================================
 Rails::Initializer.run do |config| 
   ...
   config.gem "tidy"
 end

 To install the gem on another machine, 
 run rake gems:install

＃Usage & Examples
＃===========================================
 require 'tidy'

# This might be required if your app is crashing. 
# This is only available in the forked tidy. 
# see Installation above
Tidy.fresh_tidy_version = true 

 Tidy.path = '/usr/lib/tidylib.so'
 html = '<html><title>title</title>Body</html>'

 Tidy.open(:show_warnings=>true) do |tidy|
    puts tidy.options.show_warnings # returns True
    xml = tidy.clean(html) # See note below

    puts tidy.errors # array
    puts tidy.diagnostics # array
    puts xml
  end

Note: The code above will add a DOCTYPE, html, head, body tags where
appropriate, if they do
not exist.

If you would like to check and clean an HTML SNIPPET, use these options:

    opts = {
      :show_warnings => true,
      :show_body_only => true,
      :doctype => 'omit',
      :indent => true, # optional 
    }

    Tidy.open(opts) do |tidy|
      puts tidy.clean(html)
      diagnostics = tidy.diagnostics 
      errors = tidy.errors 
    end
