Was hitting another issue where 2.3 behaves differently (Fixnum vs Integer)
https://travis-ci.org/github/JoshCheek/seeing_is_believing/jobs/670780677

Just not worth it to try and maintain an unsupported unmaintained old Ruby
that behaves differently than the newer ones.

Seeing Is Believing

Evaluates Ruby code, recording the results of each line. Integrates with any extensible editor (I've integrated it with many already, see the list). If you like Swift Playgrounds, you'll like SiB.

Helpful links

Examples

  • Watch a longer video.
  • Watch John Cinnamond use it in a presentation at the 10:22 minute mark.
  • Avdi uses it in Ruby Tapas, an amazing resource for developers in general and Ruby Developers in particular!

Known Issues

  • Assumes utf-8 everywhere. If this is an issue, please see the encodings section of the wiki.

Inspiration

Shout outs

  • Whitequark for all the work on Parser, which dramatically dramatically improved SiB (I used to have my own horribly shitty line-based parser)
  • Travis CI... I love you times a million! So many difficult bugs have been caught by this. It's so easy to work with, astoundingly convenient, helps me guarantee that SiB works on everyone else's computers, too. And it's free since SiB is open source. I literally have a Travis CI sticker on my laptop, I love you that much.
