I have used the Sheet music archive as an opportunity to learn a little about coding WordPress plugins. I think the code is good enough now to show to the world. 🙂 So, take a look on https://github.com/svenax/wp-plugin-sheetmusic/ if you are interested.

The plugin itself is pretty simple. I have also started on some general WordPress support classes that may come in handy if I decide to code more plugins. We’ll see …

One thing I found out is that you can not use plugin_dir_url(__FILE__) if your plugin directory is a symlink. I’d consider this a bug and will report it to WordPress, but a fix for the time being is to use plugins_url('my-dir') instead.
