LexiconlangProcedural constructed languages

Deterministic, seeded conlangs with phonotactics, lexicons, culture-specific naming, and visual glyph systems.

🎯

Deterministic by construction

Pin a seed, ask for content. Same seed → byte-identical output across machines, runs, and library versions. Save = seed.

🗣

Names with meaning

Every name decomposes into morphemes with English translations. Drakaztum isn't just a string — it's “Strong-anvil.”

🌀

Hierarchical seeds

ctx.child(label) forks a deterministic sub-stream. Order-independent, patch-stable, perfect for lazily-generated worlds.

✨

Visual glyph systems

Optional SVG / Unicode / Canvas glyphs per culture. Same seed → identical writing system, every time.

🧩

Composable primitives

compose, oneOf, weightedList, repeat, map, chain — strategies inter-operate behind one Generator interface.

📦

Tree-shakeable genre packs

Pull in only the cultures and generators you need: fantasy, sci-fi, modern, or build your own.

At a glance

import { fantasy } from "@lexiconlang/fantasy";

const game = fantasy.withSeed("campaign-1");

const name = game.npc.name.full;
// → { form: "Drakaztum Ironforge",
//     translation: "Strong-anvil Iron-forge",
//     language: "fantasy.dwarvish" }

Hand the same seed to a friend's machine and they generate the same NPC, the same tavern, the same dragon. Encode v:N into the path to support player-driven rerolls without disturbing the rest of the world.

What's new in v0.3

@lexiconlang/glyphs — visual writing systems with SVG / Unicode / Canvas renderers.
Per-culture glyph registries on dwarvish, elvish, humanoid, and insectoid cultures.
Three mapping strategies — phoneme, morpheme, and holistic.
Zero breaking changes — glyphs are opt-in; existing code keeps working.
