Support for FIM (Fill-in-the-middle) ?

[dtrckd]

Hi,

With the recent introduction of Codestral (https://mistral.ai/news/codestral/), I am wondering if a support is planned or would be easy to implement for nvim, particularly with the FIM feature. So far, I haven't seen any implementation that handles this for Vim.

What I have in mind is the ability to activate the FIM mode in "copilot" mode to suggest auto-completion at the cursor automatically with a customizable backend. Specifically, I would like to:

• Control when the suggestion is triggered or not
• Control the timeout to trigger the call
• Control cycling through suggestions
• Control the context window size send (prompt and suffix)

What do you think about this ?
