gettext-based localization

This page is part of the web mail archives of SRFI 29 from before July 7th, 2015. The new archives for SRFI 29 contain all messages, not just those from before July 7th, 2015.

The SRFI doesn't discuss any existing localization APIs.
I suggest it might be a better to come up with an API
that can work with existing tools and standards.  Specifically,
I would recommend an API that can be implemented using the
GNU gettext package.

I suggest these two functions:

  Look for translations for the package named PACKAGE-NAME.
  The translation files are in LOCALE-DIR, which has an
  implemengtation-specific default.

(gettext "MESSAGE")
  Look for a translation for "MESSAGE".  If one is found,
  return it; otehrwise return "MESSAGE" unchanged.

  (textdomain 'hello-program)
  (display (format (gettext "Hello, ~a!") myname))

A trivial no-op implementation:
(define (textdomain . args) 'ignore)
(define (gettext msg) msg)
