return {

        'Sam-programs/cmdline-hl.nvim',
        event = 'VimEnter',
        opts = {
            type_signs = {
                [":"] = { " ", "Title" },
                ["/"] = { " ", "Title" },
                ["?"] = { " ", "Title" },
                ["="] = { " ", "Title" },
            },
            -- custom formatting/highlight for commands
            custom_types = {
                -- ["command-name"] = {
                -- [icon],[icon_hl], default to `:` icon and highlight
                -- [lang], defaults to vim
                -- [showcmd], defaults to false
                -- [pat], defaults to "%w*%s*(.*)"
                -- [code], defaults to nil
                -- }
                -- lang is the treesitter language to use for the commands
                -- showcmd is true if the command should be displayed or to only show the icon
                -- pat is used to extract the part of the command that needs highlighting
                -- the part is matched against the raw command you don't need to worry about ranges
                -- e.g. in '<,>'s/foo/bar/
                -- pat is checked against s/foo/bar
                -- you could also use the 'code' function to extract the part that needs highlighting
                -- ["command-name"]  = false -- to disable a type
                ["lua"] = { icon = " ", icon_hl = "Title", lang = "lua" },
                ["help"] = { icon = "? ", icon_hl = "Title" },
                ["substitute"] = { pat = "%w(.*)", lang = "regex", show_cmd = true },
            },
            input_hl = "Title",
            -- used to highlight the range in the command e.g. '<,>' in '<,>'s
            range_hl = "FloatBorder",
            ghost_text = false,
            -- a function that returns the ghost text to display on the cursor
            -- by default shows ghost text for the next history match, you can complete it by pressing <up>
            -- WARNING: ghost_text_provider isn't called in a safe context use custom ones from plugins like nvim-cmp might result in crashes
            -- calling it in a safe context results in the command-line being really slow to update
            ghost_text_provider = require('cmdline-hl').calculate_ghost_text
            -- highlight used for rendering ghost text
            ghost_text_hl = 'Comment',
            inline_ghost_text = false,
        }
    }
}

Known issues

Since this uses messages if something echos anything the command-line will disappear, But that's unlikely to happen while editing the command-line, I still made a function disable_msgs to disable messages in the command-line you can call it with require('cmdline-hl').disable_msgs() make sure to call it before your notification plugin loads if you have any.

The Press-Enter prompt appears incorrectly when using multiptle commands e.g. :ls<cr>:ls you could fix it by pressing space once u see the prompt. 🔨 got fixed by some sort of side effect? (this is why you should make good git commits)

Errors in nested command-lines will still render the command-line, e.g. :<C-r>=f<cr> raises an error the plugin will keep rendering the cmdline until the user exits the command-line,
When the Press-Enter bug happens this issue is fixed.
