wtchr

Simple file/directory watcher. (Node.js)

API

It's quite simple to create a wtchr for a directory.

$3

``
wtchr(path, [options]);
`

#### path
- an absolute dircetory path

#### options:
- persistent (boolean) default: `true`
- interval (integer) default: `500`
- ignore (regexp) default: `/(\/\.DS_Store$)/`

#### Example:

`javascript
var watch = wtchr('/my/watch/base/directory');
`

Wtchr provides simple event bindings. The event API is quite similar to jQuery events, so most of JS developers are familiar with it.

bind an event

`
.on(type, [selector], handler(path, curr lstat, prev lstat))
`

unbind an event

`
.off(type, [selector], [handler(path, curr lstat, prev lstat)])
`

#### type:
- one of the 3 supported types `create` / `change` / `delete`

#### selector
- a minimatch path selector (simply a filter)

#### handle:
- a event handler

#### Example:

`javascript
var watch = wtchr('/my/watch/base/directory')

watch.on("create", "*.js", function (path, curr, prev) {
console.log("New file: " + path);
});

watch.off("create");
`

Chaining:

`javascript
wtchr('/my/watch/base/directory')
.on("create", "*.js", function (path, curr, prev) {
console.log("New file: " + path);
})
.on("change", "*.js", function (path, curr, prev) {
console.log("File changed: " + path);
})
.on("delete", "*.js", function (path, curr, prev) {
console.log("File deleted: " + path);
})
.off("create")
.off("delete");
`

Simply destroy the wtchr object with the destroy method.

`
.destroy()
`

#### Example:

`javascript
var watch = wtchr('/my/watch/base/directory')

watch.destroy();
