[ruby-core:62616] [ruby-trunk - Feature #9846] Regexp#to_regexp
From:
wconrad@...
Date:
2014-05-16 12:33:00 UTC
List:
ruby-core #62616
Issue #9846 has been updated by Wayne Conrad.
File 0001-re.c-rb_reg_to_regexp-add-to_regexp.patch added
----------------------------------------
Feature #9846: Regexp#to_regexp
https://bugs.ruby-lang.org/issues/9846#change-46753
* Author: Wayne Conrad
* Status: Open
* Priority: Low
* Assignee:
* Category:
* Target version:
----------------------------------------
There should be Regexp#to_regexp, just as there is Array#to_ary and String#to_str.
p [].to_ary # => []
p ''.to_str # => ""
p //.to_regexp # undefined method `to_regexp`...
The use case is code like this:
if o.respond_to?(:to_ary)
# do something with o.to_ary
elsif o.respond_to?(:to_str)
# do something with o.to_str
elseif o.respond_to?(to_regexp) # can't do this today
# do something with o.to_regexp
The workaround is to use Regexp.try_convert. Regexp.try_convert accepts either a Regexp or an object that responds to #to_regexp; so this code works fine (and is in some ways better):
elsif re = Regexp.try_convert(o)
# do something with o
Still, that Regexp does not respond to #to_regexp surprised me. Does it surprise anyone else?
