Frequently Asked Questions
What is the Online Ruby Editor?
It is an online utility designed to quickly edit, format, and download Ruby source code without requiring a local Ruby environment.
Does this editor run Ruby code server-side?
No. The editor acts as a client-side text editor and scratchpad. Your Ruby code is kept secure in your browser sessions.
Can I install external Ruby Gems?
No, this scratchpad is designed for raw Ruby scripts and does not support bundler or external Gem package installations.
Can I download my Ruby file?
Yes. Click the "Download" button to export your code block as a `.rb` script file.
Does it support syntax highlighting?
Yes, the editor provides full syntax coloring and auto-indents for Ruby code structures (loops, modules, classes, and def blocks).
Is there an execution time limit?
Since there is no server execution block, there are no timeout restrictions for editing and writing scripts.
Can I use this editor on my mobile phone?
Yes. The layout is optimized to work on mobile browsers so you can inspect or copy Ruby code snippets on the go.
Does it support standard Ruby library modules?
You can draft scripts using all standard library components, making it ideal for preparation, code audits, or snippet storage.
