How to disable keymap?

[powerman]

I've tried both nil and '' here but it does not work:

    require("codecompanion").setup({
        extensions = {
            history = {
                enabled = true,
                opts = {
                    -- Keymap to open history from chat buffer (default: gh)
                    keymap = "",
                    -- Keymap to save the current chat manually (when auto_save is disabled)
                    save_chat_keymap = "",

I'm opening saved chats from Action Palette and using auto-save, so I don't need both these keymaps.

            prompt_library = {
                ['Code workflow'] = { opts = { index = 5 } }, -- Give a place for Saved Chats.
                ['Saved Chats ...'] = {
                    strategy = 'chat',
                    description = 'Browse saved chats',
                    opts = {
                        index = 4,
                        stop_context_insertion = true,
                    },
                    condition = function()
                        local history = require('codecompanion').extensions.history
                        local have_chats = not vim.tbl_isempty(history.get_chats(chat_filter))
                        local mode = vim.api.nvim_get_mode()
                        return have_chats and (mode.mode == 'n' or mode.mode == 'i')
                    end,
                    prompts = {
                        n = function()
                            local history = require('codecompanion').extensions.history
                            history.browse_chats(chat_filter)
                        end,
                        i = function()
                            local history = require('codecompanion').extensions.history
                            history.browse_chats(chat_filter)
                        end,
                    },
                },
            },

@powerman It was due to the tbl_deep_extend which doesn't force nil values on the default opts. I have pushed a fix and you can update the extension and set them to false instead. Thanks

Looks like this breaks compatibility with codecompanion feature which show active keymaps by pressing ? in chat window.
In case of nil and false values I get this on ?:

In case of '' value I get this on attempt to open first chat window:

The last one is probably valid result of empty keymap, but the first one is probably a bug either in this plugin or in CodeCompanion itself.

In case of nil and false values

Actually it happens with any values, including default keymapping.

[powerman]

Sorry, looks like I broke this somewhere else in my config some time ago but noticed just now. This issue is not related to history extension.

[powerman]

Okay, false works for me, thanks!

P.S. The issue with ? happens because of this commit in mcphub: ravitemer/mcphub.nvim@1871067 - description must not contain \n.
