Add special highlights for markdown docs (underline/strike/bold etc)

[SrWither]

when the signature help appears, the colors of the first line are not visible

in theory it should look like this:

It's not only the first line.

To me it seems the signature help is rendered as plain Markdown.

I think it is not the bug of this plugin.

And also I don't think nvim-cmp's bug because nvim-cmp uses vim.lsp.util.stylize_markdown as render.

So, it may be the LSP server sending different docstrings depending on completion or not?

[hrsh7th]

Sorry. It's maybe an improvements point at the nvim-cmp side, I think.

But it's difficult. I can't think of a solution for it at the moment. So take a long time to improve this.

I'm trying to add <cmp-annotate>...</ cmp-annotate> to a native lsp syntax rule. However, I cannot manage nested syn-region rules at the moment. If someone has a solution. I want help.

The following code is not work correctly...

    --  lua/view/docs_view.lua
    ...
    vim.api.nvim_buf_call(self.window:get_buffer(), function()
      vim.cmd([[syntax clear]])
    end)
    vim.lsp.util.stylize_markdown(self.window:get_buffer(), documents, {
      max_width = maxwidth,
      max_height = documentation.maxheight,
    })
    vim.api.nvim_buf_call(self.window:get_buffer(), function()
      vim.cmd(([[syntax region %s matchgroup=Conceal start=+<cmp-annotate>+ end=+</cmp-annotate>+ contained containedin=ALL concealends keepend oneline]]):format('CmpMarkdownAnnotate'))
    end)
    ...
