Internationalisation helper

This crate maily expose a macro that wraps gettext in a convinient ways. See the documentation of the tr! macro.

To translate a rust crate, simply wrap your string within the tr! macro. One can then use the xtr binary to extract all the translatable from a crate in a .po file. GNU gettext tools can be used to process and translate these strings.

The tr! macro also support support rust-like formating.

Example:

#[macro_use]
extern crate tr;
fn main() {
// use the tr_init macro to tell gettext where to look for translations
tr_init!("/usr/share/locale/");
let folder = if let Some(folder) = std::env::args().nth(1) {
folder
} else {
println!("{}", tr!("Please give folder name"));
return;
};
match std::fs::read_dir(&folder) {
Err(e) => {
println!("{}", tr!("Could not read directory '{}'\nError: {}",
folder, e));
}
Ok(r) => {
// Singlular/plural formating
println!("{}", tr!(
"The directory {} has one file" | "The directory {} has {n} files" % r.count(),
folder
));
}
}
}
