Font Anatomy Tools for Typescript

This is a collection of tools for working with font anatomy in Typescript.

Installation

pnpm add @adam-rocska/font-anatomy

npm install @adam-rocska/font-anatomy

Usage

Command Line Utilities

All utilities do and will assume inputs from stdin and outputs to stdout. This is to allow for easy chaining of commands and general composition.

Example with pnpx:

cat Poppins-BoldItalic.ttf | pnpx @adam-rocska/font-anatomy -o md > Poppins-BoldItalic.md

Example with a global install:

my-font.ttf | font-anatomy --output-format=md > font-anatomy.md

Library units

import { fromFontFile } from '@adam-rocska/font-anatomy';
import { relativize } from '@adam-rocska/font-anatomy';

// It takes a `PathLike` so you can pass a string, URL or a `Buffer`
const fontAnatomy = fromFontFile('path/to/font.ttf');
console.log(fontAnatomy);
