Set process.env[DEBUG] given process.argv

npm i @maboiteaspam/set-verbosity --save

Using the node process.argv value

var pkg = require('./package.json');
var debug = require('@maboiteaspam/set-verbosity')(pkg.name, process.argv);
// or var debug = require('@maboiteaspam/set-verbosity');
//    .raw(pkg.name, process.argv.join(' '));

debug('hello');

Which then, can be invoked in such fashion

module-name -v
module-name --verbose
module-name -v module-name
module-name --verbose module-name,tomate,set-verbosity

Using minimist module to pre parse values

var pkg = require('./package.json');
var argv  = require('minimist')(process.argv.slice(2));
var debug = require('@maboiteaspam/set-verbosity')(pkg.name, argv.v || argv.verbose);
// or var debug = require('@maboiteaspam/set-verbosity');
//  .parsed(pkg.name, argv.v || argv.verbose);

debug('hello');

Which then, can be invoked in such fashion

module-name -v
module-name --verbose
module-name -v module-name
module-name --verbose module-name,tomate,set-verbosity

This module returns instances of debug module

var pkg = require('./package.json');
var debug = require('@maboiteaspam/set-verbosity')(pkg.name, process.argv);

debug('hello');

Which then, can be invoked in such fashion

module-name -v
module-name --verbose
module-name -v module-name
module-name --verbose module-name,tomate,set-verbosity

setVerbosity is a function object with two additional methods raw, parsed.

• setVerbosity(string name, object arg) debug

When typeof(arg) is object, returns setVerbosity.raw(name, arg)

• setVerbosity(string name, string arg) debug

When typeof(arg) is string, returns setVerbosity.parsed(name, arg)

• setVerbosity(string name, bool arg) debug

When typeof(arg) is bool, returns setVerbosity.parsed(name, arg)

• setVerbosity.parsed(string name, string verboseModules)

Set process.env['DEBUG'] to verboseModules.

• setVerbosity.parsed(string name, bool verbose) debug

Set process.env['DEBUG'] to name.

• setVerbosity.raw(string name, string argv) debug

Parse argv to extract -v || --verbose (verboseModules)?. Set process.env['DEBUG'] to verboseModules or name.

• setVerbosity.raw(string name, bool verbose) debug

Set process.env['DEBUG'] to name.

var pkg = require('./package.json');
var debug = require('@maboiteaspam/set-verbosity')(pkg.name, process.argv);
var debug = require('@maboiteaspam/set-verbosity').raw(pkg.name, process.argv);

var argv  = require('minimist')(process.argv.slice(2));
var debug = require('@maboiteaspam/set-verbosity')(pkg.name, argv.v || argv.verbose);
var debug = require('@maboiteaspam/set-verbosity').parsed(pkg.name, argv.v || argv.verbose);
