I try to put an array of modules in argv.mod(), but it doesn't work the console said :
Cannot read property 'description' of undefined.
I am new to js I can only know the mod function use some recursive call along with the option function to decompose the module object. Could anyone share how to do it? I am not sure this function is supported

sometimes, we have to waring or notice user how important about the command line type.
like this:

--version
     displays version info
     xxx.js --version
--remove, -r
    remove the project --- (!important, be careful use this) <= red color
    xxx.js --remve or xxx.js -r

This could very well be a personal choice of some sort, but I feel obliged to provide at least a little information when I get an NPM warning:

npm WARN package.json [email protected] No repository field.

If you would care to you can add repository information to your package.json:

{
  "repository": {
    "type": "git",
    "url": "https://github.com/codenothing/argv.git"
  }
}

because why not 😄

Given this code:

import argv from 'argv';

argv.option([
  { name: 'port', type: 'int' },
  { name: 'host', type: 'string' },
]);

const args = argv.run();
console.log(args);

It doesn't capture the values without an =

node bug.js --port 6969 --host 0.0.0.0
{
  targets: [ '6969', '0.0.0.0' ],
  options: { port: NaN, host: 'true' }
}

It does with with an =

node bug.js --port=6969 --host=0.0.0.0
{ targets: [], options: { port: 6969, host: '0.0.0.0' } }

But the docs shows an example using it with a space. Is there a setting I'm not seeing? Or a bug?

Can I add an option with a default value?

Looks like the CI build is failing due to some outdated dependencies:

preventing #8 from merging automatically

I have a NodeJS program that uses the "argv" package.
When, in the command line, you specify a unexpected (a wrong) parameter for my program, it end its execution.
I have checked that, and I have discovered that it's because "argv" call to "process.exit".
Could you change the implementation of "agv" for making that behaviour configurable?
I believe that is a bad practice that a package calls to "process.exit"; that call sould be issued only by the main program.

When you put two or more dollar '$' chars into an argument:

POC

#index.js
var argv = require( 'argv' );

let options = [{
    name: 'comment',
    type: 'string',
}];
var args = argv.option( options ).run();
console.log(args.options.comment);

The you do on terminal:
node index.js --comment="Hey, do you want some $$$$"

Expected result:
"Hey, do you want some $$$$"

Result:
"Hey, do you want some 114349114349"
