## The at Module
|
||||||
|
|
||||||
|
The at module provides a single function `at()` which can be used to schedule
|
||||||
|
repeating (or non-repeating) tasks to be done at a particular time.
|
||||||
|
|
||||||
|
### at() function
|
||||||
|
|
||||||
|
The utils.at() function will perform a given task at a given time in the
|
||||||
|
(minecraft) day.
|
||||||
|
|
||||||
|
#### Parameters
|
||||||
|
|
||||||
|
* time24hr : The time in 24hr form - e.g. 9:30 in the morning is '09:30' while
|
||||||
|
9:30 pm is '21:30', midnight is '00:00' and midday is '12:00'
|
||||||
|
* callback : A javascript function which will be invoked at the given time.
|
||||||
|
* worlds : (optional) An array of worlds. Each world has its own clock. If no array of worlds is specified, all the server's worlds are used.
|
||||||
|
* repeat : (optional) true or false, default is true (repeat the task every day)
|
||||||
|
|
||||||
|
#### Example
|
||||||
|
|
||||||
|
To warn players when night is approaching:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
var utils = require('utils'),
|
||||||
|
at = require('at');
|
||||||
|
function warning(){
|
||||||
|
utils.players(function( player ) {
|
||||||
|

|
||||||
|
});
|
||||||
|
}
|
||||||
|
at('19:00', warning);
|
||||||
|
```
|
||||||
|
To run a task only once at the next given time:
|
||||||
|
```javascript
|
||||||
|

|
||||||
|

## The watcher Module
|
||||||
|
|
||||||
|
This module exposes functions for watching for changes to files or directories.
|
||||||
|
|
||||||
|
### watcher.watchFile() function
|
||||||
|
|
||||||
|
Watches for changes to the given file or directory and calls the function provided
|
||||||
|
when the file changes.
|
||||||
|
|
||||||
|
#### Parameters
|
||||||
|
|
||||||
|
* File - the file to watch (can be a file or directory)
|
||||||
|
* Callback - The callback to invoke when the file has changed. The callback takes the
|
||||||
|
changed file as a parameter.
|
||||||
|
|
||||||
|
#### Example
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
var watcher = require('watcher');
|
||||||
|
watcher.watchFile( 'test.txt', function( file ) {
|
||||||
|
console.log( file + ' has changed');
|
||||||
|
});
|
||||||
|
```
|
||||||
|
***/
|
||||||
|
var filesWatched = {};
|
||||||
|
var dirsWatched = {};
|
||||||
|
|
||||||
|
exports.watchFile = function( file, callback ) {
|
||||||
|
if ( typeof file == 'string' ) {
|
||||||
|
file = new File(file);
|
||||||
|
}
|
||||||
|
filesWatched[file.canonicalPath] = {
|
||||||
|
callback: callback,
|
||||||
|
lastModified: file.lastModified()
|
||||||
|
};
|
||||||
|
};
|
||||||
|
|
||||||
|
/************************************************************************
|
||||||
|
### watcher.watchDir() function
|
||||||
|
|
||||||
|
Watches for changes to the given directory and calls the function provided
|
||||||
|
when the directory changes. It works by calling watchFile/watchDir for each
|
||||||
|
file/subdirectory.
|
||||||
|
|
||||||
|
#### Parameters
|
||||||
|
|
||||||
|
* Dir - the file to watch (can be a file or directory)
|
||||||
|
* Callback - The callback to invoke when the directory has changed.
|
||||||
|
The callback takes the changed file as a parameter.
|
||||||
|
For each change inside the directory the callback will also
|
||||||
|
be called.
|
||||||
|
|
||||||
|
#### Example
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
var watcher = require('watcher');
|
||||||
|
watcher.watchDir( 'players/_ial', function( dir ) {
|
||||||
|
console.log( dir + ' has changed');
|
||||||
|
});
|
||||||
|
```
|
||||||
|
***/
|
||||||
|
|
||||||
|
exports.watchDir = function( dir, callback ) {
|
||||||
|
if ( typeof dir == 'string' ) {
|
||||||
|
dir = new File(dir);
|
||||||
|
}
|
||||||
|
dirsWatched[dir.canonicalPath] = {
|
||||||
|
callback: callback,
|
||||||
|
lastModified: dir.lastModified()

exports.watchDir(file,callback);

/************************************************************************

|
### watcher.unwatchFile() function
|
||||||
|
|
||||||
|
Removes a file from the watch list.
|
||||||
|
|
||||||
|
#### Example
|
||||||
|
```javascript
