@suchipi/run-main

A helper function suitable for use in command-line applications. Runs the user-provided "main" function (which can be sync or async), and if it errors, formats the error message, prints it to stderr, and calls process.exit(1).

``ts
export function runMain(
/**
* The function to run. If it's async, it'll be awaited.
*/
mainFunction: () => any,
runOptions?: {
/**
* The function used to exit when an error occurs. If called, it will
* receive the value 1.
*
* Defaults to process.exit.
*/
exit?: (code: number) => void;
/**
* The function used to print the formatted error text.
*
* Defaults to console.error, which writes to stderr.
*/
printError?: (formattedError: string) => void;
/**
* The function used to convert an unknown value to a string when a
* non-error value is thrown.
*
* Defaults to require("util").inspect.
*/
inspect?: (value: any) => string;
},
): Promise;
