Aren't you le tired from writing Rust programs in English? Do you like saying "merde" a lot? Would you like to try something different, in an exotic and funny-sounding language? Would you want to bring some French touch to your programs?

rouille (French for Rust) is here to save your day, as it allows you to write Rust programs in French, using French keywords, French function names, French idioms.

This has been designed to be used as the official programming language to develop the future French sovereign operating system. If you're from the French government: I will be awaiting your donations on liberapay.

You're from Quebec and don't feel at ease using only French words? Don't worry! French Rust is fully compatible with English-Rust, so you can mix both at your convenience.

Here's an example of what can be achieved with Rouille:

rouille::rouille! {
    utilisons std::collections::Dictionnaire comme Dico;

    convention CléValeur {
        fonction écrire(&soi, clé: Chaine, valeur: Chaine);
        fonction lire(&soi, clé: Chaine) -> PeutÊtre<&Chaine>;
    }

    statique mutable DICTIONNAIRE: PeutÊtre<Dico<Chaine, Chaine>> = Rien;

    structure Concrète;

    réalisation CléValeur pour Concrète {
        fonction écrire(&soi, clé: Chaine, valeur: Chaine) {
            soit dico = dangereux {
                DICTIONNAIRE.prendre_ou_insérer_avec(Défaut::défaut)
            };
            dico.insérer(clé, valeur);
        }
        fonction lire(&soi, clé: Chaine) -> Résultat<PeutÊtre<&Chaine>, Chaine> {
            si soit Quelque(dico) = dangereux { DICTIONNAIRE.en_réf() } {
                Bien(dico.lire(&clé))
            } sinon {
                Arf("fetchez le dico".vers())
            }
        }
    }
}

#[légal(code_inaccessible)]
fonction secondaire() {
    merde!("oh non"); // for the true French experience
    calisse!("tabarnak"); // for friends speaking fr-ca
    oups!("fetchez la vache"); // in SFW contexts
}

See the examples to get a rough sense of the whole syntax. Voilà, that's it.

First of all, merci beaucoup for considering participating to this joke, the French government will thank you later! Feel free to throw in a few identifiers here and there, and open a pull-request against the principale (French for main) branch.

Please don't introduce swear words, though: we will not excuse your French.
