log-styling

Tiny utility for formatting console output.

It provides an easier-to-use interface than the printf-like console.log.

example

import { styled, style, resetStyle, object, generic, log } from "log-styling";

const heading = (text) => styled(`
    font-size: 1.1em;
    font-weight: bold;
    text-decoration: underline;
`, `# ${text}\n`);

const bold = (text) => styled("font-weight: bold", text);

log(console.log, [
    heading("Styled text (styles can be nested)"),
    styled("color: lightgreen", [
        "Lightgreen letters.\n",
        style("color: yellow"),
        "Yellow letters.\n",
        style("background: black"),
        "Lightgreen letters on a black background.\n",
        resetStyle,
        "Lightgreen letters.\n",
        bold("Bold lightgreen letters.\n"),
    ]),
    "Unstyled letters.",
    heading("Any values"),
    object({ answer: 42, bool: true }),
    "\n",
    object(Symbol.toPrimitive),
    "\n",
    generic(/[Rr]egexp?/),
]);
