ParsiLocalize

Enhance I18n localize to use Parsi digits and Jalaly dates in Farsi (فارسی) locale.

For changing digits in string/integer/float with Unicode Parsi ones, we use parsi-digits:

require 'parsi-localize'
I18n.l

Another useful feature of parsi-digits is that you can parse strings with Unicode digits to numerics:

"۱۲۳۴۵".to_i
  => 12345
"۱۹/۸".to_f
  => 19.8

To have a real localization of dates in I18n#localize (converting them to Jalali date), we uses parsi-date:

I18n.l Time.now, fromat: "%y/%m/%d %H:%M:%S"
  => "۹۰/۱۰/۱۳ ۰۵:۴۳:۳۲"

As you know, date and time formats can be stored in the locale file. For example with

fa:
  time:
    formats:
      default: "%y/%m/%d %H:%M:%S"
      short: "%d %B، %H:%M"
      long: "%A، %e %B %Y، ساعت %H:%M:%S"
  date:
    formats:
      default: "%y/%m/%d"
      short: "%d %B"
      long: "%A، %e %B %Y"

in your locale file, you will get:

date = Date.today
I18n.l date
  =>
