Things I build for fun

Two Telegram bots that people use every month, and three small tools I built to scratch my own itch.

thewatbot

An inline Telegram dictionary

Type @thewatbot and a word in any Telegram chat, and definitions appear as you type. Pick one and it drops into the conversation, so nobody has to leave the chat to look something up.

Definitions come from Wiktionary's REST API. The bot strips the markup, skips entries like “plural of…” and “alternative spelling of…”, and formats the rest for Telegram.

Sample definitions. The real bot asks Wiktionary as you type.

WeatherBot

Is it cold? Weather, inline

Type @iscoldbot and a place in any chat, pick the right match, and the bot posts the current weather. Buttons under the message swap it, in place, for the forecast, sunrise and moon phase, or air quality rated on the UK DEFRA and US EPA scales.

It's built with Deno and grammY on WeatherAPI. Places you've looked up are cached in Deno KV, so an empty query offers your recent locations straight away.

portray

Beautiful images from source code

A library (@darvesh/portray on npm) that turns a code snippet into a PNG or JPEG, with a choice of themes, border colours, font sizes, custom fonts and three styles of window controls.

It can return the image as a Buffer or as a readable stream, so you can pipe it straight into a file or an HTTP response.

  • Node.js
  • wkhtmltopdf
  • npm
Source ↗npm ↗

↓ try it

import { generate } from "@darvesh/portray";

// code in, picture out
const image = await generate(code, {
  theme: "dracula",
  borderColor: "#ABB8C3",
  fontSize: 25,
  windowControl: 1,
});

polytope

Excel formulas over arrays of objects

Spreadsheet formulas, but for JSON: give polytope an array of objects and a formula such as =SUM({price}), and it evaluates the formula against the data. Curly braces refer to fields.

It's a work in progress, built on parser combinators and tested with Bun.

dgrep

A 40-line grep on mmap

A tiny grep. It mmaps the file, walks it byte by byte with memcmp, and prints the line around each match. There's no read buffer and no copying, just a pointer into the mapped file.

It's case-sensitive and deliberately bare: an exercise in memory-mapped I/O.

try:

The real file, and the real quirks: matching is case-sensitive, and a line prints once for every match in it.

The demos give an idea of how each project works. They're made for this page and don't run the real projects.
