Passing an empty selection to API

[syaghoubi00]

With the addition of agents, I wanted to setup a keybinding to do a quick @perplexityai search, however, a nil selection causes the entire buffer to be passed to perplexity by default.

The goal is to be able to ask a generic question, not based on the current visual selection or buffer.

I'm not sure of the best approach to working around this.
Maybe implementing require("CopilotChat.select").empty?

The current keybind code:

    -- Ask the Perplexity agent a quick question
    {
      "<leader>aS",
      function()
        local input = vim.fn.input("Perplexity: ")
        if input ~= "" then
          require("CopilotChat").ask("@perplexityai " .. input, {
            selection = nil
          })
        end
      end,
      desc = "Quick Chat with Perplexity (CopilotChat)",
      mode = { "n", "v" },
    },

---

UPDATE - The fixed keymap, following @deathbeam's answer:

    -- Ask the Perplexity agent a quick question
    {
      "<leader>aS",
      function()
        local input = vim.fn.input("Perplexity: ")
        if input ~= "" then
          require("CopilotChat").ask(input, {
            agent = "perplexityai",
            selection = false,
          })
        end
      end,
      desc = "Perplexity Search (CopilotChat)",
      mode = { "n", "v" },
    },

[deathbeam]

you can set selection to false and then it should work

[deathbeam]

Also as side note, you can also use agent = 'perplexityai' for the function instead of using @perplexityai, its going to be a bit cleaner probably and remembered in the chat

Working, Thanks!

Getting a warning about a type mismatch, but other than that, all good.

Diagnostics:
1. Cannot assign `boolean` to `fun(source: CopilotChat.source):(CopilotChat.select.selection)?|nil`.
   - `boolean` cannot match `fun(source: CopilotChat.source):(CopilotChat.select.selection)?|nil`
   - `boolean` cannot match any subtypes in `fun(source: CopilotChat.source):(CopilotChat.select.selection)?|nil`
   - Type `boolean` cannot match `fun(source: CopilotChat.source):(CopilotChat.select.selection)?`
   - Type `boolean` cannot match `nil` [assign-type-mismatch]

[deathbeam]

Awesome. And the type mismatch should be fixed now as well

Hi @syaghoubi00 This is a nice usage. Could you open a PR this? Thanks

[syaghoubi00]

@deathbeam already patched the type issue with #731. Maybe in the wiki there could be an examples/tips sections and I could add the keybind example to that?

[jellydn]

You could add to readme as it has a section for this
