## What it is
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

## Facets
- artifact type: cli-tool

- function: developer-tools, interpreter, editor
- domain: developer-tools, programming-languages, text-editors
- platform: ruby, cli, cross-platform
