Saving chat using chat title

[thezetrax]

Is it possible to take a generated title from the chat and use it to save the chat? Like something in zed.dev? Automatically save the chat using a generated title from the chat itself?

[deathbeam]

Hmm so :CopilotChatSave/:CopilotChatLoad is not enough with specifying custom title? The load function also has autocomplete so it shouldnt be that hard to use I think. And imo if saving chat its better to specify custom name anyway as thats more accurate, but depends on what other ppl think.

Would it be possible to configure something similar? using the available api?

[deathbeam]

Technically yes, you can set up default callback with response, then get for example first line of response, set it to some variable if the variable is not set and then generate some name from that, then create command that calls .save/load methods with this saved variable on CopilotChat

ok tried playing with it a bit and this kinda works (e.g feeding the response to AI, then using AI to generate the chat title)

local function generate_title(response)
    local prompt = [[
        Generate chat title for:

        ```
        %s
        ```

        Output only the title and nothing else in your response.
    ]]

    chat.ask(prompt:format(response), {
        callback = function(gen_response)
            print(response)
        end
    })
end

and setting that as default callback. but currently it also prints this to chat so there is no way to prevent that. but i can add option for not printing to chat.

@deathbeam awesome, will try it thank you

ok tried to add boolean config for not using chat and history, looks like it works (thats messages buffer at bottom)

[deathbeam]

local chat = require('CopilotChat')

vim.keymap.set({ 'n', 'v' }, '<leader>ax', function()
    vim.g.chat_title = nil
    chat.reset()
end)

chat.setup({
    -- Your other configs etc...

    callback = function(response)
        if vim.g.chat_title then
            chat.save(vim.g.chat_title)
            return
        end

        local prompt = [[
        Generate chat title in filepath-friendly format for:

        ```
        %s
        ```

        Output only the title and nothing else in your response.
        ]]

        -- use AI to generate prompt title based on first AI response to user question
        chat.ask(vim.trim(prompt:format(response)), {
            headless = true, -- disable updating chat buffer and history with this question
            callback = function(gen_response)
                vim.g.chat_title = vim.trim(gen_response)
                print('Chat title set to: ' .. vim.g.chat_title)
                chat.save(vim.g.chat_title)
            end
        })
    end,
})

ok here is working implementation. it saves the generated chat title to vim.g.chat_title. It also auto saves the chat under that title.

It also adds custm keybind for copilot chat reset as you probably want to reset the title as well when you reset the chat.

Can see it saving here:

@deathbeam Can this be a feature request as well?

[deathbeam]

feature request?

[thezetrax]

Can we have an option similar to this natively from the plugin options?

require('CopilotChat').setup({
	autosave = true
})

[deathbeam]

I think just doing it yourself is more flexible, you can format the name however you want, dont rly see a reason why to integrate it personally. Also some people might want to autosave just 1 chat based on same name so asking AI to generate the name woul dbe also waste of time for them, or save 1 chat per workspace (which is what I would personally do if i wanted autosave instead of ai generated chat name). So I dont think 1 generic boolean covers it, and adding bunch of configuration to cover all use cases is worse than just letting ppl use existing api that supports the feature.
