summary: The WP Syntax Plugin is another plugin that simplifies posting source code
|

|
In my searching, I have found another WordPress source code plugin, called [wp-syntax][]. This one uses [GeSHi][], the Generic Syntax Highlighter. It features many languages, and is extensible to even more. (If I ever post a COBOL snippet, I'll probably add COBOL support to it, and contribute it to the codebase.)
|
||
|
|
|
||
|
|
To use it, you simply put a pre tag, followed by `lang=[language]`. It will also do line numbering. Of course, with a single "language" parameter, the embedded language will not be highlighted as well. In this case, the previous plug-in works better; although the syntax highlighting has to be done manually, it can handle multiple languages.
|
||
|
|
|
||
|
|
_(NOTE: The samples have been removed, as this blog is not running under WordPress. However, since the source code from another post was moved here, it is presented below, using [Jekyll][]'s PHP highlighting mode.)_

{% codeblock lang:php %}
|
||
|
|
<?php
|
||
|
|
/**
|
||
|
|
* This creates a list of category links that can be used with a category dropdown
|
||
|
|
*/
|
||
|
|
$aCategories = get_all_category_ids();
|
||
|
|
$iMaxCat = 0;
|
||
|
|
foreach($aCategories as $iThisCat) {
|
||
|
|
if ($iMaxCat < $iThisCat) {
|
||
|
|
$iMaxCat = $iThisCat;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
$iMaxCat++;
|
||
|
|
?>
|
||
|
|
<div style="text-align:center;">
|
||
|
|
<form name="categoryform" action="" style="text-align:center;">
|
||
|
|
<script type="text/javascript">
|
||
|
|
var aLink = new Array(<?php echo($iMaxCat); ?>);
|
||
|
|
<?php
|
||
|
|
foreach($aCategories as $iThisCat) {
|
||
|
|
echo("aLink[$iThisCat] = \"" . get_category_link($iThisCat) . "\";\n");
|
||
|
|
} ?>
|
||
|
|
function goCat() {
|
||
|
|
window.location =
|
||
|
|
aLink[document.getElementById('cat')[document.getElementById('cat').selectedIndex].text;
|
||
|
|
}
|
||
|
|
</script>
|
||
|
|
<?php wp_dropdown_categories('class=sidebardropdown&orderby=name&show_count=1&hierarchical=1'); ?>
|
||
|
|
<br /><br />
|
||
|
|
<button class="sidebarbutton" type="button" style="margin-top:5px;" onclick="goCat();">View Category</button>
|
||
|
|
</form>
|
||
|
|
</div>
|
||
|
|
{% endcodeblock %}
|
||
|
|
|
||
|
|
This is another option, and is probably what I'll use for single-language posts, or posts where the embedded language may not be crucial.
