common utility methods
ninjs-core.argv -> minimist wrapper
https://github.com/substack/minimist
parse argument options
This module is the guts of optimist's argument parser without all the fanciful decoration.
example
var argv = require('minimist')(process.argv.slice(2));
console.dir(argv);
$ node example/parse.js -a beep -b boop
{ _: [], a: 'beep', b: 'boop' }
$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
{ _: [ 'foo', 'bar', 'baz' ],
x: 3,
y: 4,
n: 5,
a: true,
b: true,
c: true,
beep: 'boop' }
methods
var parseArgs = require('minimist')
var argv = parseArgs(args, opts={})
Return an argument object argv
populated with the array arguments from args
.
argv._
contains all the arguments that didn't have an option associated with
them.
Numeric-looking arguments will be returned as numbers unless opts.string
or
opts.boolean
is set for that argument name.
Any arguments after '--'
will not be parsed and will end up in argv._
.
options can be:
opts.string
- a string or array of strings argument names to always treat as stringsopts.boolean
- a boolean, string or array of strings to always treat as booleans. iftrue
will treat all double hyphenated arguments without equal signs as boolean (e.g. affects--foo
, not-f
or--foo=bar
)opts.alias
- an object mapping string names to strings or arrays of string argument names to use as aliasesopts.default
- an object mapping string argument names to default valuesopts.stopEarly
- when true, populateargv._
with everything after the first non-optionopts['--']
- when true, populateargv._
with everything before the--
andargv['--']
with everything after the--
. Here's an example:> require('./')('one two three -- four five --six'.split(' '), { '--': true }) { _: [ 'one', 'two', 'three' ], '--': [ 'four', 'five', '--six' ] }
Note that with
opts['--']
set, parsing for arguments still stops after the--
.opts.unknown
- a function which is invoked with a command line parameter not defined in theopts
configuration object. If the function returnsfalse
, the unknown option is not added toargv
.
ninjs-log
advanced logging using DEBUG env var with advanced typed formating, fs output, middleware mappings, and color mappings
ninja setup (Windows exmaple)
set NODE_ENV=development && set DEBUG="api:twitter"
usage
First, setup your environment variables, NODE_ENV and DEBUG.
NODE_ENV environment var
The NODE_ENV environment var specifies your runtime nodejs env and is used by several npm modules to alter configuration. For example, the 'express' server module changes caching and all sorts of optimations based on this value.
Typical values include : "development", "production" Advanced values include : "test", "staging", "local"
If NODE_ENV === "production", NO log messages will leak to output.
DEBUG environment var
DEBUG environment var specifies what keyed log messages are allowed to leak to the output (ie. stdout or log.txt or log.json) The express server module changes caching and all sorts of optimations based on this value.
Example on Windows:
set NODE_ENV=development
set DEBUG="api:twitter"
or
set NODE_ENV=development && set DEBUG="api:twitter"
process.env
NODE_ENV === "production" No logs leak DEBUG=* All logs leak DEBUG=something:blah:* Contains 'something:blah:' logs leak DEBUG=something:blah Equals 'something:blah' logs leak
- set DEBUG=*
- set DEBUG=specific:file
