Thank you for refactoring the padding and this approach, being self-contained, is definitely cleaner.

Also thank you for the style and doc comment cleanup. Do you use a style guide or equivalent of stylua? I tried to match the existing style as best I could, but it's a subjective guess sometimes.

For helpers.node_text(), in #25, I elected for a separate version (node_multiline_text()) that always return a table, for consistency. I found that if a node can't be multiline, I safely call node_text() for a string and otherwise, call the multiline variant and use the table. I found that helped write cleaner code. Just something to consider. I'm not sure of the best approach.

Yea, no worries man :) It took me a bit of playing with to figure out the context thing, but in the end I think you solved the problem really nicely.

Truth be told, the style stuff is mostly just whatever the lua-lsp autocorrects to. But I don't mind little things here-and-there, so no worries. It is pretty subjective at the end of the day.

I'm leaning towards changing the function signature for the helper to always return a table, like in your version, even for single line nodes. But I'm not sure. It would be consistent with how an action can return a string for single line things, and a table of strings for multi line. I think I'll put off making that decision for now.
