Seeing Is Believing is a Ruby command-line tool and library that evaluates Ruby code and records the result of every line, annotating the file with inline output. It integrates with extensible editors to provide a playground-like experience similar to Swift Playgrounds.

Use cases

• show the result of each line of ruby code inline
• use ruby like a playground with instant feedback
• annotate ruby code with evaluated values in my editor
• debug ruby scripts by seeing intermediate values
• teach ruby by displaying expression results per line

When to choose

• you write Ruby and want inline per-line evaluation results in an extensible editor
• you want a Swift-Playgrounds-like experience for Ruby
• you need a library to programmatically evaluate Ruby and capture per-line results

When to avoid

• you work in languages other than Ruby
• you need a full debugger with breakpoints and stepping
• your project requires non-UTF-8 encodings
