What do you mean with "ident"?

See TSynPasSyn. Search for everything containing the word "fold".
Basically:
- define an enum for every fold block type (see TPascalCodeFoldBlockType).
- define a range class (for example TSynRubySynRange, you can copy  
TSynPasSynRange and rename all Pas in Ruby). The range class is needed  
to store the code fold state for every line of synedit. (all lines  
with the same state share the same range object).
Martin, maybe some parts can be moved to a TSynCustomHighlighterFoldedRange?
- then see all overrides in TSynPasSyn. I guess Ruby will do many  
things similar, just with other enums and keywords.

Maybe Martin can give a small paragraph, how the store/restore of code  
fold ranges work. Then we can put that all together and put into a  
wiki page.

Great.

Yes.
I already started a few things. For example you can register your own  
identifier completion. I plan to support other compilers too.
