After a mighty tussle with regular expressions (it’s always a mighty tussle with those dratted things) I have completed adding support for default values for embed attributes. That means you can create embeds that have optional attributes (or parameters, if you want to call them that).
Normally, if you forget to specify a value for an attribute when you use an embed, then it just doesn’t work, usually with ugly results. But if you give your attributes defaults, then you don’t have to set all the attribute values for an embed every time you use it.
I am putting together several examples of how to use default attribute values that I will post in the Embedder section of the web site once I have uploaded the new version of the plugin, which should be sometime this weekend, I hope.
