WoodChopper

Selective logging based on command line arguments and keys.

Written in CoffeeScript, usable in JavaScript.

Usable with all the console methods, as seen in this list from Mozilla.

Installation

$ npm install woodchopper

Use

Run your node program in the command line with the --print or -p flag and the keys you want to print:

$ node program.js --print important secure

Then in your code give your print statements their keys:

var chop = require('woodchopper');

chop.log(['important', 'superfluous'], 'This is the first print message');
chop.log(['superfluous', 'detail'], 'This is the second print message');
chop.log(['detail', 'secure'], 'This is the third print message');

This would result in the following messages being printed:

'This is the first print message'
'This is the third print message'

Running the program like this:

$ node program.js --print detail

Will result in:

'This is the second print message'
'This is the third print message'

If you give a print statement only one key you do not need to put it in an array:

    chop.log('superfluous', 'This is the fourth print message');
