WP-Markdown treating java generics like HTML tags

Question

With some Java generic code in a code block, ie:

List<Integer> l = new ArrayList<Integer>();

WP-Markdown was treating as HTML, and no matter what I did, the code above got turned into something like

List<Integer> l = new ArrayList</Integer><Integer>();</Integer>

Is there any way to get WP Markdown to behave better with this kind of code? Gist and (clearly) Stackexchange don't have this problem.

Answer 1

You could write a shortcode to pass your Java code into that runs htmlentities on it. That should get it to display correctly.

function clean_java($atts, $content)
{
    return htmlentities($content);
}

add_shortcode('clean_java', 'clean_java');

Usage:

[clean_java]List<Integer> l = new ArrayList<Integer>();[/clean_java]

WP thinks your Java code is HTML code. Essentially, make it HTML code instead.
