VSCode: Folding all @doc at once
Is there a way to fold/unfold all occurrences of
@doc"""
[...]
"""
within a module at once (using a command or assigned keystroke) in VSCode?
Was talking to a colleague and have no idea where to look/ask at all.
Guess its part of language aware folding
Are there other editors which support this?

Fold All Block Commentsnever worked in VSCode using Lexical here
That’s the problem. So sorry I didn’t think to check. Language aware code-folding is only implemented right now in ElixirLS:
So you have to use ElixirLS as your LSP instead of Lexical to get the language aware folding.
Reminder: it’s generally the language server protocol (LSP) that implements features like code folding, not specific editors. That’s basically the point of LSPs: each editor just implements the protocol. That way communities don’t need to write a new language server per editor. So switching to Zed or Atom won’t fix your problem (unless of course that editor happens to implement its own LS for the language in question, but that’s not usually the case).

⌘K ⌘2 will do it for @doc in VSCode on MacOS.
The number indicates the level of indentation you want to fold. So ⌘K ⌘1 would fold the top-level defmodule, ⌘K ⌘2 folds all the 2nd level indented regions like @doc and def, ⌘K ⌘3 would fold all the highest-regions inside each def, etc.
Note: the default is that the command won’t fold the region where your cursor is. So if you’re trying to fold a particular @doc, make sure your cursor is outside it.

Vim certainly does and is actually on my list to write one for this very purpose. I have not done so yet but if you’re interested I’ll share here when done. Otherwise see :help fold-expr if you’re curious.

Oh and ⌘K ⌘J unfolds everything.
