Started tech blogging and found it is necessary to have a nice code highlighter, and I was actually looking out for a blogging tool that would appear very simpler, nice, less time to post, and still have good control over minor aspects. Trying to achieve all this using wordpress, and found a good friend coderay (when looked inside html from m.onkey.org).
Now.. to have any code snippet here on the blog I just have to say “to_wordpress_html” as follows

def to_wordpress_html file_path
return unless file_path
require 'coderay'
html = CodeRay.scan_file( file_path, :ruby).div(:line_numbers => :table)
html = "<div style=\"overflow:auto;margin-top: 5px;\">#{html}</div>"
html.sub!('class="code"><pre>', ' class="code"><pre style="padding-left: 2px;margin-bottom: 0;padding-bottom: 0;"> ')
html.sub!('<pre><a href="#n1" ',' <pre style="border-right: 1px solid gray;padding-left: 2px;padding-right: 2px;margin-bottom: 0;padding-bottom: 0;"><a href="#n1" ')
html.sub!('class="CodeRay"', ' class="CodeRay" style="margin-bottom:0;" ')
html.sub!('class="line-numbers"', ' class="line-numbers" style="padding:0;" ')
html.sub!('class="code"', ' class="code" style="padding:0;" ')
end
if not ARGV[0]
puts "Require ruby file."
else
File.open('code.html','w'){ |file| file.write to_wordpress_html(ARGV[0]) }
end
# ruby coderay_for_wordpress.rb coderay_for_wordpress.rb

May be I will later add support for lines from and to, and more…
