Access Ruby Hash Using Dotted Path Key String

Question

The Rails I18n library transforms a YAML file into a data structure that is accessible via a dotted path call using the t() function.

t(\'one.two.three.four\         


        

Answer 1

There is also HashDot.

HashDot allows dot notation syntax use on hashes. It is faster, and more traversable than an object created with OpenStruct.

a = {b: {c: {d: 1}}}
a.b.c.d => 1
