Calling dependency function in opts

[LamprosPitsillos]

Using the below config throws an error ( understandably ) about

require('ts_context_commentstring.integrations.comment_nvim').create_pre_hook(),

not being found, since it isnt installed yet.
What is the proper way to handle this?

I thought that using the config = function () and setup in there should fix the issue.

{
        "numToStr/Comment.nvim",
        dependencies = { 'JoosepAlviste/nvim-ts-context-commentstring' },
        opts = {
            padding = true,
            sticky = true,
            ignore = nil,
            toggler = {
                line = 'gcc',
                block = 'gbc',
            },
            opleader = {
                line = 'gc',
                block = 'gb',
            },
            extra = {
                ---Add comment on the line above
                above = 'gcO',
                ---Add comment on the line below
                below = 'gco',
                ---Add comment at the end of line
                eol = 'gcA',
            },
            mappings = {
                ---Operator-pending mapping; `gcc` `gbc` `gc[count]{motion}` `gb[count]{motion}`
                basic = true,
                ---Extra mapping; `gco`, `gcO`, `gcA`
                extra = true,
            },
            pre_hook = require('ts_context_commentstring.integrations.comment_nvim').create_pre_hook(),
            post_hook = nil,
        }
    }

Your code snippet works in my config.

LazyVim includes the following nvim-ts-context-commentstring spec:

{
    "JoosepAlviste/nvim-ts-context-commentstring",
    lazy = true,
    opts = {
      enable_autocmd = false,
    },
}

In my own config, on top of LazyVim, I define Comment.nvim as follows:

{
    "numToStr/Comment.nvim",
    keys = {
      { "gc", mode = { "n", "v" }, desc = "Comment toggle linewise" },
      { "gb", mode = { "n", "v" }, desc = "Comment toggle blockwise" },
    },
    opts = function()
      local commentstring_avail, commentstring = pcall(require, "ts_context_commentstring.integrations.comment_nvim")
      return commentstring_avail and commentstring and { pre_hook = commentstring.create_pre_hook() } or {}
    end,
}

Can you share the error message?
