Code Folding

[epbuennig]

Description

It would be great if the web editor supported folds of certain elements. Folds are sections of source code which can be folded to only show as a single line.

An example in Visual Studio Code:

Elements that I would like to fold:

• multiline comments and multiline sections of single line comments
• multiline code statements
  • multiline blocks and expressions
  • multiple successive imports
  • multiple successive show and/or set rules
  • possible long string literals
• certain sections of markdown
  • all content between 2 headings of the same level
  • list/enum/terms shorthand syntax
  • math blocks if multiline

In a case where more than one fold icon would appear on the same line, the one which would fold the largest code section would take precedence. I.e.:

1 #set func(
2   ...
3 )
4 #set page("a4")

Should be folded to

1 #set func( // ...
5

Use Case

• reduce visual clutter when editing large documents
• ignore sections which are rarely edited (imports, prelude show/set rules)
• ignore sections which are not being edited (finished sections, small script sections, etc.)
• ignore sections which are being edited by other users in multiplayer scenarios
  • I have not used the multiplayer feature, but if text jumps around because of other users editing above one's own cursor this would certainly help

Also please make paragraphs collapsible!

For the online editor at least, it would be great to have a feature akin to Notion's toggle shortcut ">" to hide a lot of text
