Padre integration

Well, Padre is really incredibly extensible - except for one thing (I'm going to have to patch my current copy); you can't add a MIME type/file extension mapping from a plugin, which is very disappointing. So here's basically what I'm doing:

• Add .dpl => application/x-decl to EXT_MIME in Padre::MimeTypes.pm (patch)
• Create a Padre::Plugin::Decl.pm
• There, registered_documents can assign x-decl to Padre::Document::Decl.pm
• Create Padre::Document::Decl.pm

The Plugin module handles general UI stuff (menus, About, special tools, etc.) while the Document module customizes the editor's behavior to suit you. I'm particularly interested in folding - but so far the documentation is really chaotic.

I've got about ten windows open on this task:

• Gábor's overview of wxPerl and wxWidgets
• Somebody's cookbooks for plugins. I find these cookbooks essentially impenetrable.
• Padre::Plugin, Padre::Document, Padre::Document::Perl, Perl::MimeTypes
• Another how-to on plugins

Also, I had some initial success with creating a new document class and doing some rudimentary folding in it - it was harder than hell to find documentation, though. It's scattered all around the Web. Here's some links that came in handy when dealing with folding in Scintilla/wxStyledTextControl:

• Somewhat random access, but here is some POD for the wxScintilla control.
• Here's some guy doing folding against Scintilla in a language I haven't even identified.
• Otherwise, there's loads of stuff written for/about wxPython that works pretty well.
