does not maintain state

Here's "irb" in the Terminal:

irb(main):001:0> x = 7 => 7 irb(main):002:0> 4 * x => 28

Here's RubyCalc:

>> x = 7 => 7 >> 4 * x => -:1: undefined local variable or method `x' for main:Object (NameError)

See? RubyCalc doesn't remember variable values. So if I wanted to use Ruby as a calculator, why wouldn't I just use "irb" in the Terminal?

does not maintain state - emaNneercS

Hello,

This is interesting. For my personal use, I do not need to maintain state; actually, RubyCalc is not designed to be a replacement for the IRB, it just aims at being a little calculator easily reachable (does not need to launch a terminal).
However, you're right : it would be better anyway.
For the RubyCalc app, this is rather easy. I will certainly have more problems to make it work with the widget, but I will try.

Thanks for your comment,

Pierre Chatelier
