IfTrue-IfFalse

A gem to emulate as similar as possible the smalltalk ifTrue and ifFalse messages.

This gem doesn't only execute the closure, but it returns the value of the closure evaluation.

Add this line to your application's Gemfile:

gem 'if_true_if_false'

And then execute:

$ bundle

Or install it yourself as:

$ gem install if_true_if_false

These are the three ways of use this gem

true_condition.if_true { 'ok' } #will execute and return what is into the closure

false_condition.if_true { 'ok' }.if_false { 'false' } #will execute and return what is into the second closure, namely, 'false'

false_condition.if_true { 'ok' } #will return false_condition and won't execute the closure

false_condition.if_false { 'false' } #will return 'false' as expected

Since the way Ruby treats blocks and semantically wouldn't be right, this case is not taken into account:

any_condition.if_false { 'something' }.if_true { 'other' }

Namely, if_false can't be before if_true
