wannabesrevenge 7d943ef1f2 Stop walk from descending into next directory
Added ability to stop the walk from descending into a given
directory.
You use this by calling  in either the 'directory' or 'name' event
handler. This will prevent the directory from being traversed.

node-walk
====
# 2021 Update
Consider using [`@root/walk`](https://npmjs.org/package/@root/walk) instead.
I created `walk` quite literally a decade ago, in the Node v0.x days.
Back then using an EventEmitter seemed like the thing to do. Nowadays,
it seems a bit overkill for the simple task of walking over directories.
There's nothing wrong with `walk` - it's about the same as it was 10 years ago -
however, at only 50 lines of code long, `@root/walk` is much simpler and much faster.
# node-walk
| a [Root](https://rootprojects.org) project
nodejs walk implementation.
This is somewhat of a port python's `os.walk`, but using Node.JS conventions.
* EventEmitter
* Asynchronous
* Chronological (optionally)
* Built-in flow-control
* includes Synchronous version (same API as Asynchronous)
- EventEmitter
- Asynchronous
- Chronological (optionally)
- Built-in flow-control
- includes Synchronous version (same API as Asynchronous)
As few file descriptors are opened at a time as possible.
This is particularly well suited for single hard disks which are not flash or solid state.
Installation
----
## Installation
npm install walk
```bash
npm install --save walk
```
Usage
====
# Getting Started
```javascript
'use strict';
var walk = require('walk');
var fs = require('fs');
var walker;
var options = {};
walker = walk.walk('/tmp', options);
walker.on('file', function (root, fileStats, next) {
fs.readFile(fileStats.name, function () {
// doStuff
next();
});
});
walker.on('errors', function (root, nodeStatsArray, next) {
next();
});
walker.on('end', function () {
console.log('all done');
});
```
## Common Events
All single event callbacks are in the form of `function (root, stat, next) {}`.
All multiple event callbacks callbacks are in the form of `function (root, stats, next) {}`, except **names** which is an array of strings.
All **error** event callbacks are in the form `function (root, stat/stats, next) {}`.
**`stat.error`** contains the error.
- `names`
- `directory`
- `directories`
- `file`
- `files`
- `end`
- `nodeError` (`stat` failed)
- `directoryError` (`stat` succedded, but `readdir` failed)
- `errors` (a collection of any errors encountered)
A typical `stat` event looks like this:
```javascript
{ dev: 16777223,
mode: 33188,
nlink: 1,
uid: 501,
gid: 20,
rdev: 0,
blksize: 4096,
ino: 49868100,
size: 5617,
blocks: 16,
atime: Mon Jan 05 2015 18:18:10 GMT-0700 (MST),
mtime: Thu Sep 25 2014 21:21:28 GMT-0600 (MDT),

birthtime: Thu Sep 25 2014 21:21:28 GMT-0600 (MDT),
name: 'README.md',
type: 'file' }
```
# Advanced Example
Both Asynchronous and Synchronous versions are provided.
```javascript
(function () {
"use strict";
'use strict';
var walk = require('walk')
, fs = require('fs')
, options
, walker
;
var walk = require('walk');
var fs = require('fs');
var options;
var walker;
options = {
followLinks: false
// directories with these keys will be skipped
, filters: ["Temp", "_Temp"]
};
options = {
followLinks: false,
// directories with these keys will be skipped
filters: ['Temp', '_Temp'],
};
walker = walk.walk("/tmp", options);
walker = walk.walk('/tmp', options);
// OR
// walker = walk.walkSync("/tmp", options);
// OR
// walker = walk.walkSync("/tmp", options);
walker.on("names", function (root, nodeNamesArray) {
nodeNamesArray.sort(function (a, b) {
if (a > b) return 1;
if (a < b) return -1;
return 0;
});
walker.on('names', function (root, nodeNamesArray) {
nodeNamesArray.sort(function (a, b) {
if (a > b) return 1;
if (a < b) return -1;
return 0;
});
});
walker.on("directories", function (root, dirStatsArray, next) {
// dirStatsArray is an array of `stat` objects with the additional attributes
// * type
// * error
// * name
walker.on('directories', function (root, dirStatsArray, next) {
// dirStatsArray is an array of `stat` objects with the additional attributes
// * type
// * error
// * name
next();
});
walker.on('file', function (root, fileStats, next) {
fs.readFile(fileStats.name, function () {
// doStuff
next();
});
});
walker.on("file", function (root, fileStats, next) {
fs.readFile(fileStats.name, function () {
// doStuff
next();
});
});
walker.on('errors', function (root, nodeStatsArray, next) {
next();
});
walker.on("errors", function (root, nodeStatsArray, next) {
next();
});
walker.on("end", function () {
console.log("all done");
});
}());
walker.on('end', function () {
console.log('all done');
});
```
### Sync
Note: Due to changes in EventEmitter,
I don't think it's possible to create a truly synchronous walker,
but I believe it will still finish in a single event loop as-is
(due to changes in process.nextTick).
Note: You **can't use EventEmitter** if you want truly synchronous walker
(although it's synchronous under the hood, it appears not to be due to the use of `process.nextTick()`).
Instead **you must use `options.listeners`** for truly synchronous walker.
Although the sync version uses all of the `fs.readSync`, `fs.readdirSync`, and other sync methods,
I don't think I can prevent the `process.nextTick()` that `EventEmitter` calls.
```javascript
(function () {
"use strict";
'use strict';
var walk = require('walk')
, fs = require('fs')
, options
, walker
;
var walk = require('walk');
var fs = require('fs');
var options;
var walker;
// To be truly synchronous in the emitter and maintain a compatible api,
// the listeners must be listed before the object is created
options = {
listeners: {
names: function (root, nodeNamesArray) {
nodeNames.sort(function (a, b) {
nodeNamesArray.sort(function (a, b) {
if (a > b) return 1;
if (a < b) return -1;
return 0;
});
}
, directories: function (root, dirStatsArray, next) {
},
directories: function (root, dirStatsArray, next) {
// dirStatsArray is an array of `stat` objects with the additional attributes
// * type
// * error
// * name
next();
}
, file: function (root, fileStats, next) {
},
file: function (root, fileStats, next) {
fs.readFile(fileStats.name, function () {
// doStuff
next();
});
}
, errors: function (root, nodeStatsArray, next) {
},
errors: function (root, nodeStatsArray, next) {
next();
}
}
},
},
};
walker = walk.walkSync("/tmp", options);
walker = walk.walkSync('/tmp', options);
console.log("all done");
}());
console.log('all done');
})();
```
API
====
# API
Emitted Values
* `on('XYZ', function(root, stats, next) {})`
- `on('XYZ', function(root, stats, next) {})`
* `root` - the containing the files to be inspected
* *stats[Array]* - a single `stats` object or an array with some added attributes
* type - 'file', 'directory', etc
* error
* name - the name of the file, dir, etc
* next - no more files will be read until this is called
- `root` - the containing the files to be inspected
- _stats[Array]_ - a single `stats` object or an array with some added attributes
- type - 'file', 'directory', etc
- error
- name - the name of the file, dir, etc
- next - no more files will be read until this is called
Single Events - fired immediately
* `end` - No files, dirs, etc left to inspect
- `end` - No files, dirs, etc left to inspect
* `directoryError` - Error when `fstat` succeeded, but reading path failed (Probably due to permissions).
* `nodeError` - Error `fstat` did not succeeded.
* `node` - a `stats` object for a node of any type
* `file` - includes links when `followLinks` is `true`
* Note: This feature is broken in the current version, but works in the previous `walk-recursive` version
* `directory`
* `symbolicLink` - always empty when `followLinks` is `true`
* `blockDevice`
* `characterDevice`
* `FIFO`
* `socket`
- `directoryError` - Error when `fstat` succeeded, but reading path failed (Probably due to permissions).
- `nodeError` - Error `fstat` did not succeeded.
- `node` - a `stats` object for a node of any type
- `file` - includes links when `followLinks` is `true`
- `directory` - **NOTE** you could get a recursive loop if `followLinks` and a directory links to its parent
- `symbolicLink` - always empty when `followLinks` is `true`
- `blockDevice`
- `characterDevice`
- `FIFO`
- `socket`
Events with Array Arguments - fired after all files in the dir have been `stat`ed
