bug: markdown syntax highlighting doesn't work in chat

[matthewblott]

Describe the bug

I have a pretty bland looking chat with no colours for the code snippets:

To reproduce

Open the chat window and type a command.

Expected behavior

Avante produced code to have proper syntax highlighting.

Environment

NVIM v0.10.1
Build type: Release
LuaJIT 2.1.1720049189
OS: macOS 14.5

Repro

require('user.plugins')
require('user.config')

can you provide a reproducer? that is actually not a reproducer

[matthewblott]

Okay. I've tried a fresh install with a bare bones configuration and lazy.nvim installed at ${HOME}/.local/share/nvim/lazy.nvim. The result is the same. Here is the init.lua config in full:

local lazypath = vim.fn.stdpath 'data' .. '/lazy/lazy.nvim'

if not vim.loop.fs_stat(lazypath) then
  vim.fn.system {
    'git',
    'clone',
    '--filter=blob:none',
    'https://github.com/folke/lazy.nvim.git',
    '--branch=stable', -- latest stable release
    lazypath,
  }
end

vim.opt.rtp:prepend(lazypath)

require('lazy').setup({
  {
    'yetone/avante.nvim',
    event = 'VeryLazy',
    lazy = false,
    version = false, 
    opts = {
      provider = "openai",
    },
    build = 'make BUILD_FROM_SOURCE=true',
    dependencies = {
      'stevearc/dressing.nvim',
      'nvim-lua/plenary.nvim',
      'MunifTanjim/nui.nvim',
      {
        'MeanderingProgrammer/render-markdown.nvim',
        opts = {
          file_types = { 'markdown', 'Avante' },
        },
        ft = { 'markdown', 'Avante' },
      },
    },
  },

}) 

vim.wo.number = true
vim.wo.relativenumber = true
vim.opt.expandtab = true
vim.opt.clipboard = 'unnamedplus'

vim.g.mapleader = ' '

I tried to keep everything to a minimum. I also tried the config as suggested on the homepage of this site.

Have you tested with other languages? If they work, could you try running :TSInstall ruby? This command installs the Tree-sitter plugin for Ruby.

I've tried a few languages, it's the same issue for all of them. I've tried with Treesiter and without and the result is the same 🤷‍♂️
