JavaScript module for outputting messages. This implementation is attempting to be compatible with the console module in Node.js, http://nodejs.org/api/console.html. It requires the util module.

Methods
(static) assert(assertion, args)
If the first argument is not "truthy", then throw an error that includes a (formatted) message given by the remaining arguments.
Parameters:
| Name | Type | Description |
|---|---|---|
assertion |
The value being asserted to be true. |
|
args |
One or more additional arguments to form an error message if the assertion is false, where the first argument is optionally a formatting specification string. |
- Source:
(static) dir(object, options)
Apply util.inspect to the specified object (possibly with options) and then report as done by log(). The optional options argument is an object that may contain the following fields:
- showHidden - if true then non-enumerable properties will be shown as well. Defaults to false.
- depth - tells inspect how many times to recurse while formatting the object. Defaults to 2. Use null to get unbounded depth.
- colors - if true, then the output will be styled with ANSI color codes. Defaults to false.
- customInspect - if false, then custom inspect() functions defined on the objects being inspected won't be called. Defaults to true.
Parameters:
| Name | Type | Description |
|---|---|---|
object |
Object to send to the log. |
|
options |
Options governing how the object is described. |
- Source:
(static) error(arguments)
Same as console.log, but prefix the message with "ERROR: ".
Parameters:
| Name | Type | Description |
|---|---|---|
arguments |
One or more arguments to display in the log, where the first argument is optionally a formatting specification string. |
- Source:
(static) log(arguments)
Send a message to listeners of the JavaScript object. The first string can be a printf-style formatting string, followed by arguments to insert into the output, as for example:
console.log('My count: %d', myCount);
If the first string does not contain any formatting elements, then util.inspect()
is applied to all arguments.
Parameters:
| Name | Type | Description |
|---|---|---|
arguments |
One or more arguments to display in the log, where the first argument is optionally a formatting specification string. |
- Source:
(static) time(label)
Record the current time using the specified label for use by a later call to timeEnd().
Parameters:
| Name | Type | Description |
|---|---|---|
label |
The label for the time point. |
- Source:
(static) timeEnd(label)
Log the time elapsed since the last call to time() that gave the same label (using the log() function).
Parameters:
| Name | Type | Description |
|---|---|---|
label |
The label for the starting time point. |
- Source:
(static) trace(arguments)
Send a stack trace to the actor listener window or to stderr (if debugging is off) prefixed by "TRACE: " and any supplied (formatted) message.
Parameters:
| Name | Type | Description |
|---|---|---|
arguments |
One or more arguments to display in the log, where the first argument is optionally a formatting specification string. |
- Source:
(static) warn(arguments)
Same as console.log, but prefix the message with "WARNING: " and send to stderr (if debugging is off).
Parameters:
| Name | Type | Description |
|---|---|---|
arguments |
One or more arguments to display in the log, where the first argument is optionally a formatting specification string. |
