methodize_string
A small library that transforms UI strings into strings that can be used as method names.
It adds two methods to the String class:
String#methodize
String.methodize!
Basic usage:
require 'methodize_string'
'Save Changes'.methodize
=> "save_changes"
'Continue Reading...'.methodize
=> "continue_reading"Accented character handling:
# By default, accented characters will be converted to non-accented characters.
"Ä Ö Ü".methodize
=> "a_o_u"
# But this behavior can be overridden.
"Ä Ö Ü".methodize(transliterate: false)
=> "ä_ö_ü"Error handling:
# The non-bang method won't raise an error. It will just return nil if the string
# can't be converted.
''.methodize
=> nil
# The bang method raises an ArgumentError in cases where the string can't be converted.
''.methodize!
ArgumentError: Unable to convert string to a method string: ''Limitations
