Feature #12460: Provide Unicode Version information in a better location that UnicodeNormalize::UNICODE_VERSION

• Status: Closed

Currently, the Unicode version used in a specific version of Ruby is available
as UnicodeNormalize::UNICODE_VERSION, from lib/unicode_normalize/tables.rb.
It is rather unnatural to have to do
require 'unicode_normalize/normalize'
e.g. in test/ruby/enc/test_case_comprehensive.rb

The Unicode version is also available for make, as $(UNICODE_VERSION).

The Unicode version should be available directly in Ruby, e.g. as
RUBY_UNICODE_VERSION or some such.

+1 to avoid require to get that info, but wonder if it is worth adding new toplevel constant. Maybe place it under String:: or Regexp:: ?

Anything like that would be fine by me.

Or RbConfig::CONFIG['UNICODE_VERSION']?

RbConfig::CONFIG['UNICODE_VERSION'] looks just fine.

If I add e.g.

puts  '  CONFIG["UNICODE_VERSION"] = "$(UNICODE_VERSION)"'

as line 185 in tool/mkconfig.rb, I get a line

  CONFIG["UNICODE_VERSION"] = "$(UNICODE_VERSION)"

to show up in rbconfig.rb, but in contrast to all the other $(...) variables in that file,
it doesn't get resolved, so that I only get the following:

$ ruby -e 'puts RbConfig::CONFIG["UNICODE_VERSION"]'
$(UNICODE_VERSION)

This is as far as I got, so I'm hoping on some help from Nobu.
