The new module gettext_generated is used like this:
1> gettext_generate:compile(se, "swedish.po").
{module,se}
2> gettext_generate:compile(es, "spanish.po").
{module,es}
This generated two modules, called se and es, from gettext dot-po files.
Lets say you have an application with text you want translated.
-module(example).
-export([run/0]).
gettext(Atom) ->
case get(i18n_module) of
undefined ->
atom_to_list(Atom);
Mod ->
Mod:gettext(Atom)
end.
run() ->
io:format("~s~n", [gettext('Hello World')]).
When you run example:run() you want the translated string out.
13> put(i18n_module, se), example:run(). Hej V\344rld ok 14> put(i18n_module, es), example:run(). Hola Mundo ok
And of course, if you have no module set, it will fall back on converting the atom text to string directly.
16> erase(i18n_module), example:run(). Hello World ok
Voila!
