Looking for a Code Text Box library in JavaScript or jQuery

I am looking to add a functionality to a simple HTML where you can display your code and be able to view the plain text and print it also.

It also formats the code accordingly for brevity.

I was looking to similar to this site.

But I am not sure what are the free option开发者_StackOverflow社区s available that I could include as JavaScript file.
