Trueman

Introducing: The World's (Almost) Smallest RubyGem

Assert if a value matches one of the common forms of true or false with this little (ruby)gem :)

Installation

Add this line to your application's Gemfile:

gem 'trueman'

And then execute:

$ bundle

Usage

Trueman is designed to assert if a value is true. It does not test for presence of a value, just that it matches one of the following items:

Trueman.truthy? 1      # => true
Trueman.truthy? "t"    # => true
Trueman.truthy? "T"    # => true
Trueman.truthy? true   # => true
Trueman.truthy? "true" # => true
Trueman.truthy? "TRUE" # => true

Trueman.falsy? 0       # => true
Trueman.falsy? "f"     # => true
Trueman.falsy? "F"     # => true
Trueman.falsy? false   # => true
Trueman.falsy? "false" # => true
Trueman.falsy? "FALSE" # => true

If this list is not enough, you can easily add to the list:

Trueman.true_values  << "foo"
Trueman.false_values << "bar"

Trueman.truthy? "foo" # => true
Trueman.falsy?  "bar" # => true

Both true_values and false_values exposes a class level array. That means you can remove values, expose values or do anything else you can do on an enumerable array.

Trueman.true_values # => [1,'t','T',true,'true','TRUE']

Although it's discouraged, you can patch Object:

Trueman.patch_object!

"true".truthy? # => true
 1.truthy?     # => true
 0.falsy?      # => true
# ...
