How can I attach the current buffer to the chat window everytime I toggle CodeCompanion?

From the documentation it looks like you can do it like this, but everytime I ask the LLM for context on the current file I'm viewing it has no idea what it's looking at.

strategies = {
   chat = {
       variables = {
           ["buffer"] = {
               opts = {
                   default_params = "pin",
               },
           },
       },
   },
}

It's not possible right now: #1854

It's possible, it's just not a built-in feature.

This happens automatically. If you type gd in the chat buffer you can see the buffer context that maps to the #{buffer} variable. You will need to manually type that in, however. You could also introduce an autocmd that updates the context on the chat buffer depending on which buffer you're currently in. I will probably turn that into a feature at some point.

You could also use the prompt decorator feature. This has access to the context table on the chat buffer.

I ended up creating a custom solution to this:

	vim.api.nvim_create_autocmd("User", {
		pattern = "CodeCompanionChatCreated",
		callback = function(event)
			local chat = require("codecompanion").buf_get_chat(event.data.bufnr)
			if chat then
				-- Insert #buffer at the end of the chat buffer
				local line_count = vim.api.nvim_buf_line_count(event.data.bufnr)
				vim.api.nvim_buf_set_lines(
					event.data.bufnr,
					line_count,
					line_count,
					false,
					{ "", "#buffer", "" }
				)
			end
		end,
	})
