Re: Static, pure Scheme internationalization

Hi Vivien!
I'm also interested in Hoot for potential web frontend in Scheme.

Back to your case, as I understand, Hoot reused part of Guile code, include
i18n.
Maybe not complete yet, but it contains gettext, and G_ is its short hand.

I saw you implemented a simple G_ macro, is there any reason that it can't
meet your requirements? Or you just happend to not know it exited in Hoot?

Best regards.
Best regards.
