prompt.nvim

Plugin to chat with LLMs directly from neovim. Convenient to refine prompts and yank pieces of answers straight from a project.

To use it, simply wrap your prompt in your current buffer by inserting two tags: one to start with @ and the name of the llm (@chatgpt, @claude or @mistral), and one to end: @end. Any text in between will be sent as a prompt, and the answer will be inserted before the @end tag.

Then run :lua require("prompt.init").prompt() to get the answer inserted in your buffer.

Note: operate from markdown buffer to get the code highlighting from your setup when editing conversations with LLMs.

Installation

Requires JQ and Curl. In you neovim config folder (~/.config/nvim by default), create a new file named .llm.conf and inside, add your api key for the api you'll use:

mistral=<MISTRAL_API_KEY>
claude=<CLAUDE_API_KEY>
chatgpt=<OPENAI_API_KEY>

Available models

@mistral -> will use mistral
@claude -> will use claude
@chatgpt -> will use chatgpt

You can map tiers of model tags per llm. The default config is per below, you can overwrite it in setup to chose any available model for each llm.

local config = {
  mistral = {
    default = 'open-mistral-7b',
    small = 'open-mistral-7b',
    medium = 'mistral-small-latest',
    large = 'mistral-large-latest',
  },
  claude = {
    default = 'claude-3-haiku-20240307',
    small = 'claude-3-haiku-20240307',
    medium = 'claude-3-sonnet-20240229',
    large = 'claude-3-opus-20240229',
  },
  chatgpt = {
    default = 'gpt-3.5-turbo',
    small = 'gpt-3.5-turbo',
    medium = 'gpt-4o',
    large = 'gpt-4-turbo',
  },
}

@chatgpt medium --> will use gpt-4o
@mistral large --> will use mistral-large-latest

You can also overwrite the model with a m tag

@chatgpt small -m gpt-4o --> will use gpt-4o

example

@mistral
Write a factorial function in plain C.
@end

Your markdown buffer will be filled with the answer.

@mistral

Sure, here's a simple implementation of a factorial function in C:
``c
#include <stdio.h>
unsigned long long factorial(int n) {
    if (n == 0 || n == 1)
        return 1;
    else
        return n * factorial(n - 1);
}
int main() {
    int num;
    printf("Enter a number: ");
    scanf("%d", &num);
    printf("Factorial of %d is %llu\n", num, factorial(num));
    return 0;
}
``
This program first asks the user to input a number, then calculates and prints the factorial of that number. The factorial function itself is implemented using recursion.
@end

If you don't want to produce specifically code, and remove the default context which conditions the LLM to answer with well structured code samples, you can add the no-context argument to the tags

@mistral no-context
Write an executive summary for the project
@end
