Concealing tags with Markview

[toupeira]

I wanted to share this configuration snippet to make the chat buffer look a bit nicer 😀

This is based on the examples at https://github.com/OXY2DEV/markview.nvim/wiki/HTML#container_elements

Configuration

I use a little helper function to keep it concise, but you can also inline it if you prefer:

{
  "OXY2DEV/markview.nvim",
  lazy = false,
  opts = function()
    local function conceal_tag(icon, hl_group)
      return {
        on_node = { hl_group = hl_group },
        on_closing_tag = { conceal = '' },
        on_opening_tag = {
          conceal = '',
          virt_text_pos = 'inline',
          virt_text = {{ icon .. ' ', hl_group }},
        },
      }
    end

    return {
      html = {
        container_elements = {
          ['^buf$']         = conceal_tag('', 'CodeCompanionChatVariable'),
          ['^file$']        = conceal_tag('', 'CodeCompanionChatVariable'),
          ['^help$']        = conceal_tag('󰘥', 'CodeCompanionChatVariable'),
          ['^image$']       = conceal_tag('', 'CodeCompanionChatVariable'),
          ['^symbols$']     = conceal_tag('', 'CodeCompanionChatVariable'),
          ['^url$']         = conceal_tag('󰖟', 'CodeCompanionChatVariable'),
          ['^var$']         = conceal_tag('', 'CodeCompanionChatVariable'),
          ['^tool$']        = conceal_tag('', 'CodeCompanionChatTool'),
          ['^user_prompt$'] = conceal_tag('', 'CodeCompanionChatTool'),
          ['^group$']       = conceal_tag('', 'CodeCompanionChatToolGroup'),
        },
      },
    }
  end,
},

Oh damn this is so slick! I need to figure out how to do this in render-markdown or move plugins 😂

Haha 😀 Looks like it's not directly supported, but you might be able to hack something together with custom_handlers: MeanderingProgrammer/render-markdown.nvim#96

I did something similar for render-markdown here: https://github.com/petobens/dotfiles/blob/10b5b98b09ced0723a0d3bd549abe8f9d829efad/nvim/lua/plugin-config/render_markdown_config.lua#L95-L131

Here is the equivalent config for render-markdown.nvim

Configuration

return {
    'MeanderingProgrammer/render-markdown.nvim',
    ft = { 'markdown', 'codecompanion' },
    config = function ()
        require('render-markdown').setup({
            html = {
                enabled = true,
                tag = {
                    buf         = { icon = ' ',  highlight = 'CodeCompanionChatVariable' },
                    file        = { icon = ' ',  highlight = 'CodeCompanionChatVariable' },
                    help        = { icon = '󰘥 ',  highlight = 'CodeCompanionChatVariable' },
                    image       = { icon = ' ',  highlight = 'CodeCompanionChatVariable' },
                    symbols     = { icon = ' ',  highlight = 'CodeCompanionChatVariable' },
                    url         = { icon = '󰖟 ',  highlight = 'CodeCompanionChatVariable' },
                    var         = { icon = ' ',  highlight = 'CodeCompanionChatVariable' },
                    tool        = { icon = ' ',  highlight = 'CodeCompanionChatTool' },
                    user_prompt = { icon = ' ',  highlight = 'CodeCompanionChatTool' },
                    group       = { icon = ' ',  highlight = 'CodeCompanionChatToolGroup' },
                },
            },
        })
    end,
}

For those that can't get the markdown concealing tags to work properly, I realized these markdown configurations require html parsers to be installed in Treesitter, :TSInstall html should fix it properly

user_prompt didn't work for me, but just user did 🤔
looks like its the _ making it not hit

-- user_prompt = { icon = " ", highlight = "CodeCompanionChatTool" },
user = { icon = " ", highlight = "CodeCompanionChatTool" },
