🌙 July Ruby IDE

A lightweight Ruby learning IDE built for experimenting, learning, and executing Ruby code in real time.

This project focuses on creating a minimal but functional coding environment for beginners who want to understand how Ruby works in practice rather than relying on full-scale IDEs.

It was built in a Japanese-localized environment to simulate real Ruby learning context. 🌐 Japanese Version (日本語版)

7️⃣ Why “July”?

The project was started in June, but named “July Ruby IDE”. This name comes from Ruby, the birthstone of July.

⚙️ How it works

1. Write Ruby code inside the editor
2. Save or directly run your script
3. Code is written to a temporary file (temp.rb)
4. Local Ruby interpreter executes the file
5. Output is shown in system terminal

🚀 Run

You can download and run it directly on Windows. 🍯 Download

Or you can build it yourself using Python. 🍯 Source Code

🧪 Design Philosophy

This project is intentionally lightweight. By rethinking code execution as an observable process rather than a hidden one. (Therefore, it does not support Ruby gems.)

It is not a full IDE like VSCode or RubyMine. Instead, it is designed as a learning playground where code execution and editing logic are made visible and simple.

🧠 Why this exists

Built to understand how code execution works by building a simple IDE from scratch.

Understanding programming tools is as important as writing code itself.

This project was created to explore:

• How code editors work internally
• How execution pipelines can be simplified
• How learning environments can be designed from scratch

📌 Notes

• Execution is handled via system Ruby interpreter
• Temporary file (temp.rb) is overwritten on each run
• Designed for educational use, not production development

🧠 Core Insight

This project is not just an editor.

It is a controlled environment to observe how code execution flows from input to runtime.
