Can't get this plugin to work

[AndOrangutan]

Forgive me if I made a stupid error, but I have been up all night trying to figure this out.

I had this plugin working in my previous config and love it, especially for the code blocks. Can't seem to get it to work. Here is what I am working with:

The print('test') is a python block. in a python block that I think TS conceals.

I have tried reinstalling all plugins (deleting all plugins and packer_compile), and minimizing my config to track down the issue. Here are the relevant Lua files:

plugins.lua

------------------------------------------- Autoinstall and autoupdate for Packer --
-------------------------------------------
-- Automatically install packer
local fn = vim.fn
local install_path = fn.stdpath("data") .. "/site/pack/packer/start/packer.nvim"
if fn.empty(fn.glob(install_path)) > 0 then
    PACKER_BOOTSTRAP = fn.system({
        "git",
        "clone",
        "--depth",
        "1",
        "https://github.com/wbthomason/packer.nvim",
        install_path, }) print("Installing packer close and reopen Neovim...")
    vim.cmd([[packadd packer.nvim]])
end

-- Autocommand that reloads neovim whenever you save the plugins.lua file
--vim.cmd([[
--    augroup packer_user_config
--        autocmd!
--        autocmd BufWritePost plugins.lua source <afile> | PackerSync
--    augroup end
--]])

-- Use a protected call so we don't error out on first use
local status_ok, packer = pcall(require, "packer")
if not status_ok then
    return
end

-- Have packer use a popup window
packer.init({
    display = {
        open_fn = function()
            return require("packer.util").float({ border = vim.g.quboid_border })
        end,
    },
})

-- Install plugins --

return packer.startup(function(use)

end)

nvim-treesitter.lua

require("nvim-treesitter.configs").setup({

        --    if ok and stats and stats.size > max_filesize then
        --        return true
        --    end
        --end,
        additional_vim_regex_highlighting = { "markdown" },
    },

    --        goto_node = '<cr>',
    --        show_help = '?',
    --    },
    --},
})

Again, my deepest apologies if this is user error, I just can't figure it out for the life of me.

Can you run :lua print(require('headlines').namespace), to check if the plugin is installed correctly? It should print a number.

If that works, check if treesitter can parse the current buffer with :lua print(vim.inspect(vim.treesitter.get_parser(0, 'markdown'):parse())). This should print something like { <userdata 1> }.

Also check that the highlight groups are defined correctly with :highlight CodeBlock

I got the same problem and it turns out that I don't have a markdown parser currently installed. How do I fix this?

EDIT: I managed to install it with :TSInstallFromGrammer markdown, however now all is just grey.

here the print for :highlight CodeBlock

@DM1NIK please open a new issue

[wasden]

try this:

use {
  'lukas-reineke/headlines.nvim',
   after = "nvim-treesitter",
   config = function()
       require('headlines').setup()
    end,
}

pcall will not report errors

[AndOrangutan]

Sorry, it has been a minute, but I still can't get this to work.

Here is trying what you suggested.

So it just doesn't seem to be creating the highlights.

:PackerSync shows it's installed, so I don't really know what to do. I have tried installing and uninstalling it.

[lukas-reineke]

If the highlight group is not found, it means setup is not called.

In your config above, you have confug = function () require('headlines').setup() end. There is a typo, it should be config. Maybe that is the problem?

[AndOrangutan]

Gosh, I fill quite silly for that one.
