Markdown files don't show strikethrough

[canle1404]

Hi there. Looks like this plugin supports strikethrough but it can't be enable with my config. I tried upgrading render-markdown.nvim and tree-sitter parsers: markdown and markdown-inline but it still didn't work.
This is my config

return {
  "MeanderingProgrammer/render-markdown.nvim",
  opts = {
	  checkbox = {
		  unchecked = { icon = "" },
		  checked = { icon = "", scope_highlight = "@markup.strikethrough" },
		  custom = {
			  doing = {
				  raw = "[_]",
				  rendered = "󰄮",
				  highlight = "RenderMarkdownDoing",
			  },
			  wontdo = {
				  raw = "[~]",
				  rendered = "󰅗",
				  highlight = "RenderMarkdownWontdo",
			  },
		  },
	  },
  },
  dependencies = { "nvim-treesitter/nvim-treesitter", "nvim-tree/nvim-web-devicons" },
}

This isn't a feature of this plugin and instead It's up to your colorscheme to provide a reasonable value for the @markup.strikethrough highlight group.

If you run the command :highlight @markup.strikethrough you'll see the value that's currently set or get an error if one does not exist. This is the output for me: @markup.strikethrough xxx cterm=strikethrough gui=strikethrough.

If you don't want to change your color scheme you can also define the highlight group yourself at some point after loading your color scheme by calling:

vim.api.nvim_set_hl(0, '@markup.strikethrough', {
    strikethrough = true,
    force = true,
})

I am using ghostty and your echo example has a strike-through.

This is my nvim-treesitter config:

return { -- Highlight, edit, and navigate code
  'nvim-treesitter/nvim-treesitter',
  build = ':TSUpdate',
  opts = {
    ensure_installed = { 'bash', 'diff', 'html', 'lua', 'luadoc', 'markdown', 'go', 'javascript', 'typescript' },
    auto_install = true,
    highlight = {
      enable = true,
    },
    indent = { enable = true, disable = { 'ruby' } },
  },
  config = function(_, opts)
    require('nvim-treesitter.install').prefer_git = true
    ---@diagnostic disable-next-line: missing-fields
    require('nvim-treesitter.configs').setup(opts)
  end,
}

Looks like it should work imo 😅

Missing markdown_inline parser in ensure_installed.

The markdown parser is a bit unique in that blocks are handled separately from inline elements. The checkhealth for this plugin should show an error for the missing parser.

So, the strike-through works in ghostty but not in wezterm. I am using wezterm for my markdown notes so would be nice to get that working as well.
You're echo to test strike-through works in wezterm though but not inside neovim

[MeanderingProgrammer]

Huh, just curious, why use different terminals for different file types?

What does :checkhealth render-markdown output?

[egreb]

Because I have a raycast script that starts wezterm with my notes open, I don't think I can do that with ghostty.

open -a /opt/homebrew/bin/wezterm --args start --cwd ~/notes -- nvim -c "ZkNotes" .
