Durbat is a Rust procedural macro that enables writing Rust using Black Speech keywords, identifiers, and module paths. It maps Black Speech constructs to their Rust equivalents while remaining fully interoperable with standard Rust.

Forged to bind syntax and meaning, it offers a spare, unlit aesthetic without compromising correctness or tooling.

The name durbat derives from the Ring inscription "Ash nazg durbatulûk" — "to bind them" — reflecting the macro's role in binding Black Speech syntax to Rust.

• Black Speech keywords: e.g., gimb (fn), krimp (let), ishi (if)
• ASCII and diacritic forms supported: krîmp/krimp, dûrbat/durbat
• Translated module paths: std::collections → Zud::Gakh
• Interoperable with standard Rust; mix as needed
• Self-hosted implementation (the macro uses its own surface)

durbat::durbat! {
    aghul Zud::Gakh::Lugburz azh Lugdic;

    goth KrimpValeur {
        gimb skrith(&lat, kri: Ghash, valeur: Ghash);
        gimb lath(&lat, kri: Ghash) -> Krimpat<Gimbat<&Ghash>, Ghash>;
    }

    stuk snaga LUGDIC: Gimbat<Lugdic<Ghash, Ghash>> = Nar;

    kruk Konkret;

    krimpash KrimpValeur agh Konkret {
        gimb skrith(&lat, kri: Ghash, valeur: Ghash) {
            krimp lugdic = ghash {
                LUGDIC.mazg(Durbat::ugl)
            };
            lugdic.nakh(kri, valeur);
        }
        gimb lath(&lat, kri: Ghash) -> Krimpat<Gimbat<&Ghash>, Ghash> {
            ishi krimp Gimb(lugdic) = ghash { LUGDIC.iskh() } {
                Ash(lugdic.gruk(&kri))
            } dush {
                Burz("nazg agh lugdic".zug())
            }
        }
    }
}

durbat::durbat! {
    gimb shakh() {
        krimp snaga x = 31;

        durb x {
            42 => krimpat!("ash nazg durbatuluk"),
            _ => krimpat!("burzum ishi")
        }

        agh i ish 0..10 {
            krimp val = nazg {
                rakh i;
            };

            dur x < val {
                x += 1;
            }
        }
    }
}

#[lug(caldush)]
gimb thrakulat() {
    ghazh!("oh nar");        // standard
    pushdug!("burzum ishi"); // alias
    pushduk!("nazg");        // sanitized variant
}

Examples:

• aghul Zud::Gakh::Lugburz; → use std::collections::HashMap;
• aghul Zud::Gakh::Lugburz azh Lugdic; → use std::collections::HashMap as Lugdic;
• aghul Zud::esh; → use std::io;
• aghul Zud::Urz::Instant; → use std::time::Instant;
• aghul Zud::Grub::File; → use std::fs::File;
• aghul Zud::Lok::Mutex; → use std::sync::Mutex;
• aghul Zog::Pik; → use core::ptr;

Note: Lugburz (Lugbúrz) is used here as the Black Speech translation of HashMap.

You can use either style or mix them freely:

// With diacritics
dûrbat::dûrbat! {
    gimb shakh() {
        krîmp x = 42;
        aghul Zûd::Gâkh::Lugbúrz;
    }
}

// ASCII-only (for compatibility)
durbat::durbat! {
    gimb shakh() {
        krimp x = 42;
        aghul Zud::Gakh::Lugburz;
    }
}

Both work identically.

Add durbat to your Cargo.toml:

[dependencies]
durbat = "1.0.0"

Or for development from source:

[dependencies]
durbat = { git = "https://github.com/itsfoxstudio/durbat" }

Wrap your code in the durbat! macro:

durbat::durbat! {
    gimb shakh() {
        krimpat!("Ash nazg durbatulûk, ash nazg gimbatul!");
    }
}

Unlike hybrids that graft foreign prefixes onto English identifiers, durbat uses pure Black Speech throughout.

Preferred:

• nakh (insert)
• Zud::Gakh (std::collections)

Avoid:

• snagainsert (hybrid)
• std::collections (when Black Speech is intended)

Every keyword is a standalone, pronounceable Black Speech word with guttural consonants (gh, sh, kh, z, r, k) that feel authentically orcish.

• J.R.R. Tolkien's The Lord of the Rings and the Black Speech language
• unirust - Rust in multiple languages
