A Ruby tool that evaluates code and displays the result of every line, similar to Swift Playgrounds.
Seeing Is Believing is a Ruby tool that executes code and displays the result of every line inline, providing immediate visual feedback on program execution. It helps developers understand how values flow through their code and debug more effectively by showing exactly what each expression evaluates to.
Ruby developers who want to better understand code execution, educators teaching Ruby programming, and developers looking for visual debugging tools similar to Swift Playgrounds.
It provides unique line-by-line evaluation that no other Ruby tool offers, giving immediate visual feedback that helps with debugging, learning, and understanding complex code flows without interrupting the development workflow.
Displays the results of every line of code in your file
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Annotates every line of Ruby code with its execution result inline, providing immediate visual feedback on program flow, as demonstrated in the example GIF.
Supports many extensible editors through existing plugins, with a detailed list in the wiki, making it easy to incorporate into development workflows.
Can be used as a command-line tool, a library for programmatic access, or integrated into editors, offering versatility for different scenarios.
Specifically designed to aid learning and teaching Ruby by showing how values change during execution, inspired by educational tools like Swift Playgrounds.
Assumes all input is UTF-8, which can cause issues with legacy systems or files using other encodings, as noted in the known issues section of the README.
The process of evaluating and annotating each line adds execution time, making it less suitable for performance-sensitive applications or large codebases.
Requires integration with editors, which may involve installing plugins and configuring environments, potentially complex for some users, as indicated by the separate wiki pages for installation and integration.
Seeing Is Believing is an open-source alternative to the following products:
