The util module provides utilities to the Anchor platform.

$ component install anchorjs/util 

$ volo add anchorjs/util 

Build a formatted string using the first argument as a printf-like format.

util.format('%s %d', 'hello', 32); // 'hello 32'

util.log('message'); // => 30 Dec 22:34:31 - message util.debug('message'); // => DEBUG: message util.error('message'); // => message util.puts('message'); // => message

Build a string representation of object, which is useful for debugging.

console.log(util.inspect(util, true, null));

Check if an object is of a particular type.

util.isArray([]); util.isRegExp(/some regexp/); util.isDate(new Date()); util.isError(new Error());

Inherit the prototype methods from one constructor into another.

function MyStream() { events.EventEmitter.call(this); } util.inherits(MyStream, events.EventEmitter);

This module uses the AMD format. To include in component builds, use component-amd:

component build -u component-amd 

This module implements the interface exported by Node's Utilities module.

To run tests in a browser, execute the Make target for the desired browser:

$ make test-chrome $ make test-firefox $ make test-safari 

Headless tests can be executed directly from a terminal:

$ make test-phantomjs
