Kernel#Symbol

Returns a Symbol based on the given argument.

Add this line to your application's Gemfile:

gem "kernel-symbol"

And then execute:

bundle install

Or install it yourself as:

gem install kernel-symbol

If the argument is a symbol, returns the symbol. If the argument is not a symbol, tries to convert to a symbol.

In all other cases, returns an error.

require "kernel/symbol"

Symbol(:foo)            # => :foo
Symbol("foo")           # => :foo
Symbol(true)            # => :true
Symbol(42)              # => :"42"
Symbol(BasicObject.new) # TypeError (can't convert BasicObject into String)

The #Symbol method could be used similarly to the methods already present in the Kernel module:

• #Array
• #Complex
• #Float
• #Hash
• #Integer
• #Rational
• #String

The Kernel module is included in the Object class, so by loading this library, the #Symbol method will be available in every Ruby object.

Kernel#Symbol uses Semantic Versioning 2.0.0

• kernel-boolean: Returns a Boolean based on the given argument.
