Feature #8181: New flag for strftime that supports adding ordinal suffixes to numbers

• Status: Rejected
• Assignee: -
• Target version: 2.1.0

[tkellen (Tyler Kellen)]

This is my first issue on the ruby tracker--hopefully I'm asking in the right place?

It would be nice if you could use strftime to generate dates with ordinal suffixes. I propose the addition of another flag to support this: the @ character.

The intended usage would be:

Date.parse('2013-03-01').strftime('%B %@d, %Y')
=> "March 1st, 2013"
Date.parse('2013-03-02').strftime('%B %@d, %Y')
=> "March 2nd, 2013"
Date.parse('2013-03-03').strftime('%B %@d, %Y')
=> "March 3rd, 2013"

...etc

Assuming this would be accepted, I'd be happy to implement the feature. Could someone tell me how to proceed?

ActiveSupport has ordinalize, maybe you want to use that instead.

+1 for ActiveSupport

At least, it is not the function of strftime.

-∞ for ActiveSupport.

I don't need or want to require that giant for this simple feature. I can (and have) written a simple ordinalize method which I am currently using.

That said, I think that this:
Time.new.strftime("%a %b %@d")

...is pretty unambigously better than:
require 'activesupport'
time = Time.new
time.strftime("%a %b #{time.day.ordinalize}")

strftime currently supports several flags for formatting the time output, why not this one?

Ruby's strftime is derived from a C function standardized by ISO C90/POSIX/SUV.
So it must be careful with adding minor specifier.

Does your method support any languages other than English? If not, I'm
not sure it's suitable for inclusion into Ruby. If yes, I don't think it
will be that simple.

[From http://apidock.com/rails/ActiveSupport/Inflector/ordinalize, I
gather that Ruby on Rails doesn't support languages other than English,
either.]

Does strftime support AM/PM for different languages?

Thanks naruse, I did not know that. Could you explain what you mean by being careful?

If we add for example %@d, and then C standards add %@d as another meaning, it's a pity thing.

Therefore if you can add your extension into C standards, we can add it.
