FR: highlight 'content'

[guoang]

Great Plugin!

Is there a way to highlight the 'content'?
It'll make the function signature looks better

Same, would it be possible to have some simple colours in fold signature, it looks pretty dull right now

[anurag3301]

Seems like work the discussion has been going on for quite a while on neovim

Here are few threads

1. Issue #12649
2. PR #23471
3. PR #20750

This could be implemented now, since neovim/neovim#25209 has been merged.

I managed to do this in C, however it's nothing to do with pretty-fold plugin. If you do, tree sitter folding plugin this is an option: nvim-treesitter/nvim-treesitter#1564

You need to add the following into config file:

      vim.treesitter.query.set(
        "c",
        "folds",
        [[
          [
           (switch_statement)
           (case_statement)
           (comment)
          ] @fold
          (function_definition
            type: (type_identifier)  @fold
          )
          (function_definition
            body: (compound_statement)  @fold
          )
          ]]
      )

      vim.treesitter.query.set(
        "cpp",
        "folds",
        [[
          [
           (switch_statement)
           (case_statement)
           (comment)
           (function_definition)
          ] @fold
          ]]
      )

The above code folds this code:

An alternative approach was choosen upstream to support this: neovim/neovim#20750
