Regexp Patterns

       •   attr

           Tags: anchored, capturing

           Attribute key.

           Examples:

           Example #1.

            ".attr" =~ re("DefHash::attr");  # matches

           Example #2.

            "._attr" =~ re("DefHash::attr");  # matches

           Example #3.

            ".attr1.subattr2" =~ re("DefHash::attr");  # matches

           Example #4.

            "prop.attr1" =~ re("DefHash::attr");  # matches

           Example #5.

            "_prop._attr1" =~ re("DefHash::attr");  # matches

           Example #6.

            "Prop.attr1.subattr2.Subattr3" =~ re("DefHash::attr");  # matches

           Example #7.

            "_prop.attr1" =~ re("DefHash::attr");  # matches

           Cannot start with digit (1).

            ".0attr" =~ re("DefHash::attr");  # DOESN'T MATCH

           Cannot start with digit (2).

            "prop.0attr" =~ re("DefHash::attr");  # DOESN'T MATCH

           Cannot start with digit (3).

            "prop.attr.0subattr" =~ re("DefHash::attr");  # DOESN'T MATCH

           Invalid character: dash (1).

            ".attr-ibute" =~ re("DefHash::attr");  # DOESN'T MATCH

           Invalid character: dash (2).

            "prop-erty.attribute" =~ re("DefHash::attr");  # DOESN'T MATCH
