Maven plugin to generate HTML from Markdown now in Maven Central

Generating documents is always not the most pleasant job but it can be made easier by using easier markup language like Markdown. For that purpose I made last year a simple Markdown to HTML Page Generator Maven Plugin and now it’s also available in Maven Central.

“Markdown to HTML Page Generator” is a simple Maven Plugin which reads the input directory for Markdown files with .md suffix and outputs HTML files to target directory. There are couple of configuration options to set the input/output directories and if you want to add header and footer files to make it structurally valid HTML. The plugin uses pegdown Markdown processor.

Maven plugin artifacts can be found in Sonatypes’ OSS Maven repository:

Auto-expand WP-Syntax code blocks

Hilighting code blocks in Worpdress blog posts can be achieved with different plugins and one of them is the WP-Syntax plugin which uses GeSHi source code highlighting and supports a wide range of popular languages, highlighting with or without line numbers and maintains formatting while copying snippets of code from the browser. The plugin highlights code using HTML’s <pre> tag, e.g. <pre lang=”java” line=”1″> for Java and line numbers starting at 1.

Source code highlighting makes it easier to read examples but sometimes if your layout isn’t 900+ pixels wide, you may end up with horizontal scrollbars for wider code blocks as you can’t always make it 80 characters. But fortunately you can make the plugin auto-expand the code block when hovered over. You just have to edit the plugins code a bit as Derek MacDonald explains.

For some reason the code to auto-expand the block when hovered over has been commented out in the plugin and to enable it you’ll have to edit three files:

wp-syntax/wp-syntax.php
In method enqueueScripts(), uncomment the line that invokes wp_enqueue_script() so wp-syntax.js will be loaded.

wp-syntax/css/wp-syntax.css
Ensure the overflow, overflow-x, and overflow-y properties of class .wp_syntax are set to hidden.

wp-syntax/js/wp-syntax.js
It might be better to remove the box-shadow CSS property added during the mouseover event because it doesn’t look good in most designs.

The mouseover/mouseout expand/collapse events will be immediate with no delay.
