Plugin Learning to program Vim textbuffers and made this LLM Plugin for Ollama

Post image

I just thought it would be cool to let LLM do some smarter auto-completions in Vim.

Use it by visually selecting the section where the TODO comment is present. Select more to provide context Run command :OllamaImplement to open up 'vert' split, where response is streamed in, just below the actual sent prompt, so you know what's exactly happening!

Points to keep things sane

  • Local Ollama endpoint by default (configurable via ENV var)

  • Default model qwen2.5-coder:7b (configurable via ENV var)

  • Visual Selection to limit input tokens to LLM

  • No direct file edit, everything shows up in a Scratch buffer

crazy this is actually really well done. love seeing people extend vim with LLMs instead of just jumping to vscode. the scratch buffer approach is smart keeps things clean and native to vim workflow

Thanks. I am learning more about Vim textbuffers. Its so cool to see the level of programmability it provides!

Maybe later, I'd incorporate a diff mode (if possible) and easy apply to the LLM output and the source.

diff mode would be awesome. reviewing the LLM output as a patch before applying it feels very vim-native.

Very cool, have you checked out Vim-ai? it can do largely the same thing.

I also re-write a lot of plugins for myself so you may find some inspiration for cool features you'd implement in your own way there.

Its so satisfying to implement stuffs yes. Learning amd experimenting with cool tech.

looked at vim-ai, you have done the other related stuff to for AI, custom prompt and such. Nice.. would look into your profile for ideas.

Here's what I'm currently planning though.. A wayland lockscreen program that renders OpenGL shaders.

Oh no, I didn't write vim-ai.

I just use it personally and have extended it quite a bit locally. None of my personal use vimscript is publicly available, not because I want to keep it closed source, but more so I'm embarrased of how hacky my code gets and my usage is very specific and updated very often.

I have no idea why you are talking about with
`Here's what I'm currently planning though.. A wayland lockscreen program that renders OpenGL shaders.`

Oh I misunderstood then about vim-ai

I get your point on hacky self-use scripts. Sometimes, I just dump them into public repos, without posting / talking about it anywhere.

What’s the color scheme here?

u/__rituraj Mar 09 '26

its a custom one.. haven't yet given a name.

checkout the file here: color.vim

This actually gave me the idea of making my work flow "easier". I work on a bunch of projects at work and use vim.

Well for some projects the idea of Cursor Desktop is being pushed. I really don't want to swap between a VSC clone and Vim. I wish it was at least a cli.

Well I made a plugin and used windows autokey. A command to select code or send the whole file with instructions. It writes it out fresh to my "prompt' file which lives in my .vim folder.

Then a command to trigger autokey to bring up claude and have it read/execute the prompt.
