Jed offers the entire applicable GNU gettext spec'd set of
|
|
functions, but also offers some nicer wrappers around them.
|
|
The api for gettext was written for a language with no function
|
|
overloading, so Jed allows a little more of that.
|
|
|
|
Many thanks to Joshua I. Miller - unrtst@cpan.org - who wrote
|
|
gettext.js back in 2008. I was able to vet a lot of my ideas
|
|
against his. I also made sure Jed passed against his tests
|
|
in order to offer easy upgrades -- jsgettext.berlios.de

// also will provide a 'precompiler' that you can use at build time

// to output valid/safe function representations of the plural form

// expressions. This means you can build this code out for the most
