What are some good Web Tools to help me format my code for blogs?

I'd like to be able to copy & paste my code into textbox/textarea and have the web tool format it nicely for various popular blogging sites.

Features: Color, indentation, line numbers, etc.

Languages: C/C++/C#, VB.net, XML/HTML/Xaml, Ruby, etc.

Bloging sites: Blogger, Wordpress, etc

Answer 1

GitHub's gist service has a rather neat embedding tool and recognises loads of different languages. I've use this to embed code snippet occasionally.

Also anything based around GeSHi works great, I've had good experiences with the CodeColorer plugin for wordpress.

Answer 2

There is a guide on how you can do this here: http://codeblog.kello.se/2009/01/07/getting-code-formatting-with-syntax-highlighting-to-work-on-blogger/

It's based on syntaxhighlighter which you can read more on here http://code.google.com/p/syntaxhighlighter/

Answer 3

I like John Skeet's Code Formatter on his C# in Depth blog

Answer 4

I think the best tool I've used for the purpose is Google Code Prettify. How it works and samples you can find here.

Answer 5

I like SyntaxHighlighter and it's now incorporated into many blog sites including WordPress by default.
