Rdocs: Code Documentation Made Simple

Introduction

When working on open-source projects or internal projects, creating effective documentation is essential. As a developer, I often faced the challenge of generating and maintaining comprehensive project documentation. The example below demonstrates various types of documentation I've included:

  • Examples showcasing how to use the application configuration.
  • A README guide illustrating the usage of my CLI.
  • Code snippets demonstrating the usage of my library in different scenarios.

However, a common issue is ensuring that the examples provided in the documentation remain accurate and up-to-date. What if the example code changes? What if there's a typo in the documented code? How can we ensure that the examples always reflect the current state of the codebase?

Imagine a tool that allows you to extract code snippets, ensuring they are not only reliable but also executable. What if you could easily incorporate pieces of code that are known to work or leverage tested examples from languages like Rust, which use Doctest? This tool is designed to address these concerns.

Goal

My objectives are as follows:

  • Alignment with Code: Ensure documentation consistently aligns with the codebase.
  • CI Validation: Incorporate validation into Continuous Integration to ensure documentation validity.
  • User-Friendly: Prioritize ease of use for all stakeholders.
  • Minimal Dependencies: Enable documentation validity even without external tool dependencies.

How It Works?

The process begins with your project. Navigate to the section you wish to include in your documentation and enclose it with // 📖 #START <id:adding_numbers>. Mark the end of the section with // 📖 #END.

For instance, it should resemble this in Rust:

//📖 #START <id:adding_numbers>
fn add_numbers(a: i32, b: i32) -> i32 {
    a + b
}
//📖 #END

Next, navigate to your documentation, such as the readme.md file, and begin the section with <!-- 📖ID -->. Conclude this section with <!-- ID📖 -->.

Upon executing the command rdocs replace [COLLECT-FOLDER] [DOC-FOLDER], all examples will be gathered and seamlessly replace the corresponding content in your documentation.

Available commands:

  • rdocs replace: for replace content replacement
  • rdocs replace --check: for CI example if you want to validate that the block are equal
  • rdocs collect: show all block

Installation

Cargo install:

cargo install rdocs
