cargo-prompt

Recursively minify and concatenate source code into a markdown document for llm prompting. Optionally remove comments / documentation. Items in .gitignore are automatically excluded.

This can be useful for LLM assisted development when rapidly prompting with updated code, or when there is too much code to fit in the allowed context window.

example input

fizzbuzz/fizzbuzz.rs:

// Functions that "don't" return a value, actually return the unit type `()`
fn fizzbuzz(n: u32) -> () {
    if is_divisible_by(n, 15) {
        println!("fizzbuzz");
    } else if is_divisible_by(n, 3) {
        println!("fizz");
    } else if is_divisible_by(n, 5) {
        println!("buzz");
    } else {
        println!("{}", n);
    }
}

example output

# fizzbuzz

## ./fizzbuzz.rs

```rust
fn fizzbuzz(n:u32)->(){if is_divisible_by(n,15){println!("fizzbuzz");}else if is_divisible_by(n,3){println!("fizz");}else if is_divisible_by(n,5){println!("buzz");}else{println!("{}",n);}}
