How do I prevent Wordpress from eating my code?

Question

I'm writing a guide and putting code examples. If I use the visual editor the code indentation is lost. It will also take some code and strip it out. If I use the text editor I can't ever switch to the visual editor again or the formatting and markup is lost.

This doesn't happen in other editors like Discourse.

I'm using Geishi syntax highligher.

Is there anyway to prevent this?

If you look at the editing box, you'll see the curly braces as a choice. Highlight your code block, then use that curly braces icon. That will wrap the code in a 'code' block, so it will look like this:

<?php 
   // this is a code block
   echo "this is a code block";

You can do the same in text mode (rather than visual) by using the HTML 'code' tag.
