Hi, I'm Anton — a software engineer.

Holding it all together in the new era of agentic coding.

Termi-link

Clickable links for terminals that support them, readable plain text for the ones that don't. A near drop-in alternative to terminal-link — an existing import moves over with a small edit.

Sanitizes and encodes urls so nothing can break or hijack the escape sequence
Customizable fallback, or switch it off entirely
isSupported() detection, cross-platform (macOS, Linux, Windows)

import { terminalLink } from "termi-link";
console.log(terminalLink("example.com", "https://example.com"));
// supported:   example.com   (clickable)
// unsupported: example.com https://example.com

defold-typescript

TypeScript for the Defold game engine, transpiled to plain Lua via TypeScriptToLua. A modern, agent-friendly successor to the ts-defold family, written from scratch.

Typed self, on_message, on_input via defineScript/defineGuiScript/defineRenderScript
watch with live diagnostics, source maps for breakpoints, and --hot-reload into the running game
Completes game-object paths, component/node/animation ids and game.project keys read from your own project
Fits new and existing projects — adopt TypeScript one script at a time
Run via bunx @defold-typescript/cli@latest init

CIE 15.3 standard compliance
Tree-shakeable ESM exports

import { rgb2lab, lab2lch, lch2css } from "precise-colors";

const lab = rgb2lab({ r: 100, g: 150, b: 255 });
const lch = lab2lch(lab);
console.log(lch2css(lch)); // "lch(62.55% 62.44 279.76)"
