Small Ruby CLI Improvements (Part 3): Hirb vs. Unicode

Hirb: “A mini view framework for console/irb that’s easy to use, even while under its influence. Console goodies include a no-wrap table, auto-pager, tree and menu.” now supports unicode in two ways:

┌───────────────────────────────────────────┬───────────────────────────────────────────────┐ │ Support for unicode full-width characters │ Unicode table characters instead of +/- chars │ └───────────────────────────────────────────┴───────────────────────────────────────────────┘

Small Ruby CLI Improvements (Part 2): Wirb!

Many people use irb with wirble. I also did.

I’ve been quite happy with it, but sometimes I noted that some symbols were displayed as : without the symbol name (e.g. in method name arrays) and that the representation of regexes looked quite strange.

This is why I’ve looked at the wirble tokenizer, fixed some bugs, liked it, extended it and created Wirb. These are the improvements:

The multi mega method list

One of my favourite ways of learning something about existing code is to load it into irb and play around with it. You are able to ask every object in irb what it can do. It is as easy as you just asking for methods or public_methods and the object will show its abilities. But often you get spammed by Object or irb methods that you rarely want to use.
