files-to-prompt

files-to-prompt is a command-line tool that recursively reads all files in a specified directory and concatenates their contents into a structured format, making it easy to use as a prompt for Large Language Models (LLMs).

Credit

This project is a Rust port of the original files-to-prompt in Python by Simon Willison.

Features

• Recursively scans directories and reads all files
• Sorts files by path for consistency
• Outputs file paths along with their contents
• Handles errors gracefully if files cannot be read

Installation

To use files-to-prompt, first ensure you have Rust installed. Then, build the project:

cargo build --release

Or install it directly using:

cargo install --path .

Usage

Run the tool by providing one or more directory paths:

files-to-prompt <path1> [path2] ...

Example

files-to-prompt ./my_project

This will output:

./my_project/file1.txt
----
<contents of file1.txt>
----

./my_project/file2.rs
----
<contents of file2.rs>
----

Error Handling

• If a file cannot be read, an error message is printed.
• If no path is provided, the program exits with an error message.

Use Case

This tool is particularly useful when preparing large codebases or documentation as a prompt for an LLM, allowing users to efficiently gather and format multiple files into a structured input.
