Human-friendly process signals ported to deno.

This is a map of known process signals with some information about each signal.

Unlike os.constants.signals this includes:

• human-friendly descriptions
• default actions, including whether they can be prevented
• whether the signal is supported by the current OS

Example

import { signalsByName } from "https://deno.land/x/human_signals/mod.ts";

console.log(signalsByName.SIGINT);
// {
//   name: 'SIGINT',
//   number: 2,
//   description: 'User interruption with CTRL-C',
//   supported: true,
//   action: 'terminate',
//   forced: false,
//   standard: 'ansi'
// }
