Folding at scene_headings level

[davidbragg]

It would be extremely helpful if we could code fold scenes with scene_headings items at the start level item. Makes writing and editing easier as Atom remembers what was folded. Easy visual markers and makes things clearer.

Currently indenting scenes to use Atom's automatic folding, but this requires undoing all the indents to export appropriately. Haven't tried to see how fault tolerant other apps might be importing this indented content. Would be much nicer if it supported it in the package.

It's not entirely clear to me what you're describing here. This is a feature desired in the editor window? Outline? Exported pdf? Screenshots and links might help to demonstrate desired behavior as well as how you're working around.

Code folding in the editor, using the scene_headings item as the opener and folding everything beneath it until the next scene_headings. This way you could collapse a screenplay the same way you collapse code.

It's something I looked at briefly to see if I could implement it locally, but it's pretty far outside my wheelhouse.

Atom will do folding based on tabbing. Right now tab indenting everything in the scene. This causes output issues, either not rendering at all or honouring the indents in the formatted screenplay. I believe honouring the indents is the correct behaviour in this case, but not what I'd ultimately like.

I think part of the problem is we aren't using the new tree-sitter parser for the Fountain grammar. It would be a good improvement to recreate the grammar for tree-sitter, which would give us features like code-folding for free.

That would explain why my attempts to hack at it locally failed.

There is a script to convert grammars if you want to try getting the tree-sitter parser working. I'd be happy to accept PRs.

[davidbragg]

Script doesn't appear to be doing what I want. I keep getting left with an initialized, empty project.

Tried poking at it further and the scope of the changes required is definitely outside of my expertise.
