How do I disable some functionalities for some certain file types? For example, I want to disable indent for markdown files but have it enabled for others.

Snacks has a filtering option that you can set to false, vim.g.snacks_indent and vim.b.snacks_indent, you can use autocmd or ftplugin to set vim.b.snacks_indent to false in markdown files

Or you can just filter option.

opts = {
  indent = { 
      filter = function(buf)
           return not vim.tbl_contains({ "markdown" }, vim.b[buf].filetype)
      end
    }
}

For some reasons, the suggested code doesn't work for me, but the method using autocmd and vim.b.snacks_indent work. Here's my working config:

vim.api.nvim_create_autocmd("FileType", {
    desc = "Disable indent for markdown",
    pattern = { "markdown" },
    group = vim.api.nvim_create_augroup("snacks_group", { clear = false }),
    callback = function()
        vim.b.snacks_indent = false
    end,
})
