How to add new code folding rules?

[Areso]

Very interesting thing for me:
could I write my own code folding rules for Lazarus IDE? Or just add some my own rules to existing ones?

Without knowing what you want to add, I can only give very basic pointers.

Folding is provided by the Highlighter, and the unit SynEditFoldedView.

The HL provides what can be folded (except for folding/hiding current selected text)

There is a tutorial on the HL, that also covers the very basic of folding.

Thank you. I have read provided material. As I understand, this library commonly used for creation new text-based Code Redactors.
As for my example. I often use global variables, and I'd like to fold Unit's var section, 'cause in some projects there are a lot of them.
As for another example, I'd like to fold Try-Except-Finally construction.

global var and try except are already foldable. This is configurable.

Menu Tools > Options
Section Editor > Code Folding.

You can also define fold able areas anywhere in the code by adding to the code:

Code: Pascal  [Select][+][-]

1. {%region}
2.   // can be folded
3. {%endregion}
4.  
5. {%region /fold}
6.   // can be folded / folds by default
7. {%endregion}
8.  

And you can also select text, and fold/hide the selected lines.
That however is not restored when the IDE is restarted.
