How-to do regex in macros?

Question

{% nilable = /\:\:Nil|\?$/.match(type) %}

It doesn't seem to work: undefined macro method 'RegexLiteral#match'.

Answer 1

Macros::StringLiteral has =~ instance:

{% type = "Module::Nil" %}
{% p type =~ /\:\:Nil|\?$/ %} #=> true

{% type = "Module::Null" %}
{% p type =~ /\:\:Nil|\?$/ %} #=> false
