Add DeepSeek as a Custom Provider

[brunocroh]

I would like to know if it makes sense to add DeepSeek as one of parrot.nvim default providers.

If it makes sense for the project, let me know, I'm interested in contributing to the project and I think it could be a good first issue.

Hi @brunocroh,

Sure, go ahead and add a new provider. If possible, you can "inherit" from another provider (e.g. xAI is doing that from the OpenAI provider).

Awesome, thank you, let me do that

It's taking longer than expected because the DeepSeek API platform has been down since yesterday.
Waiting for it to be online to integrate

What's the right way to address the visible thought reasoning? The model works well but you can't use it by default for inline code edits because it will end up inserting the reasoning chain as well. Does this just need custom logic to parse out the tags from the llm output?

@naddeoa I guess this is even harder to do for a streaming response. I might need to implement something like a callback functionality where users can define some routines after the response is completed, so one could easily write a Vim command to delete that <think></think> block.

@naddeoa
It is possible to invoke commands when the PrtDone event is triggered the following way:

local augroup = vim.api.nvim_create_augroup
local autocmd = vim.api.nvim_create_autocmd

local thinking_group = augroup("remove thinking tags", { clear = true })
autocmd({ "User" }, {
  pattern = { "PrtDone" },
  callback = function()
    vim.api.nvim_command [[%s/<think>\_.\{-}<\/think>//]]
  end,
  group = thinking_group,
  desc = "Delete text enclosed by <think> and </think> on custom 'PrtDone' event.",
})

This will delete the reasoning block encapsulated in the mentioned tags.
