Richtextfx: Feature: Set Lines Visible / Code Folding

[RobertBColton]

If possible it would be nice if there could be some underlying support to hide or show line(s) n->n2
This would make it possible with paragraph graphic factory for a developer to implement code folding.

Any updates on this? Roadmap?

Am currently looking into maybe implementing this feature, will hopefully know next week sometime ....

I'd love to see this feature in any capacity. Its one of the very few downsides of migrating away from Swing/RSyntaxTextArea. If its a matter of time investment and you're busy, I'd be willing to fork/PR if you had pointers or a rough idea on how to implement the feature.

Thanks for the offer I'm doing okay at this stage :-)

I would like a vote/input on a preferred method name please:  

1. hideParagraphs  /  unhideParagraphs
2. collapseParagraphs  /  expandParagraphs
3. foldParagraphs  /  unfoldParagraphs
4. other ?

[Col-E]

If when the paragraph is collapsed there is still a line preview _(like how IDE's do it)_ then 2 or 3 seem to make the most sense.

I was hoping to submit a PR by now but I'm not yet happy with the API. So this is just to let you know that I've basically got it done and there should be a PR next week sometime. Sorry for the delay ....

[Col-E]

Don't worry about the pace, take your time.

[Jugen]

Okay, a PR has been submitted. Will merge next week sometime pending any feedback or changes .....
