I was tired of looking at cluttered output in the console -- something needed to be done,
sys.inspect()
didn't display regexps correctly, and was too verbose, and I had an hour or two to spare.
So I decided to have some fun. eyes were born.
example of the output of a user-customized eyes.js inspector
eyes also deals with circular objects in an intelligent way, and can pretty-print object literals.
var inspect = require('eyes').inspector({styles: {all: 'magenta'}});
inspect(something); // inspect with the settings passed to `inspector`
or
var eyes = require('eyes');
eyes.inspect(something); // inspect with the default settings
you can pass a label to inspect()
, to keep track of your inspections:
eyes.inspect(something, "a random value");
If you want to return the output of eyes without printing it, you can set it up this way:
var inspect = require('eyes').inspector({ stream: null });
sys.puts(inspect({ something: 42 }));
These are the default styles and settings used by eyes.
styles: { // Styles applied to stdout
all: 'cyan', // Overall style applied to everything
label: 'underline', // Inspection labels, like 'array' in `array: [1, 2, 3]`
other: 'inverted', // Objects which don't have a literal representation, such as functions
key: 'bold', // The keys in object literals, like 'a' in `{a: 1}`
special: 'grey', // null, undefined...
string: 'green',
number: 'magenta',
bool: 'blue', // true false
regexp: 'green', // /\d+/
},
pretty: true, // Indent object literals
hideFunctions: false, // Don't output functions at all
stream: process.stdout, // Stream to write to, or null
maxLength: 2048 // Truncate output if longer
You can overwrite them with your own, by passing a similar object to inspector()
or inspect()
.
var inspect = require('eyes').inspector({
styles: {
all: 'magenta',
special: 'bold'
},
maxLength: 512
});
