Filer also supports node's Path module. See the [Filer.Path](#FilerPath) section below.

In addition, common shell operations (e.g., rm, touch, cat, etc.) are supported via the

`FileSystemShell` object, which can be obtained from, and used with a `FileSystem`.

The node.js [path module](http://nodejs.org/api/path.html) is available via the `Filer.Path` object. It is
|
||||
identical to the node.js version with the following differences:
|
||||
* No support for `exits()` or `existsSync()`. Use `fs.stat()` instead.
|
||||
* No notion of a current working directory in `resolve` (the root dir is used instead)

#### fs.exists(path, callback)<a name="exists"></a>
|
||||
|
||||
Test whether or not the given path exists by checking with the file system.
|
||||
Then call the callback argument with either true or false.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
//Test if the file exists
|
||||
fs.exists('/myfile', function (exists) {
|
||||
console.log(exists ? "file exists" : "file not found");
|
||||
});
|
||||
```
|
||||
|
||||
fs.exists() is an anachronism and exists only for historical reasons. There should almost never be a reason to use it in your own code.
|
||||
|
||||
In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to fs.exists() and fs.open(). Just open the file and handle the error when it's not there.

### FileSystemShell<a name="FileSystemShell"></a>
|
||||
|
||||
Many common file system shell operations are available by using a `FileSystemShell` object.
|
||||
The `FileSystemShell` is obtained from, and used in conjuction with a `FileSystem`,
|
||||
and provides augmented features. Many separate `FileSystemShell` objects can exist per
|
||||
`FileSystem`, but each `FileSystemShell` is bound to a single instance of a `FileSystem`
|
||||
for its lifetime.
|
||||
|
||||
A `FileSystemShell` is created using the `FileSystem.Shell()` function:
|
||||
|
||||
```javascript
|
||||
var fs = new Filer.FileSystem();
|
||||
var sh = fs.Shell(options);
|
||||
var sh2 = fs.Shell(options);
|
||||
// sh and sh2 are two separate shells, each bound to fs
|
||||
```
|
||||
|
||||
The `FileSystemShell` can take an optional `options` object. The `options` object
|
||||
can include `env`, which is a set of environment variables. Currently supported variables
|
||||
include `TMP` (the path to the temporary directory), and `PATH` (the list of known paths) and
|
||||
others may be added in the future. You can also add your own, or update existing variables.
|
||||
|
||||
```javascript
|
||||
var fs = new Filer.FileSystem();
|
||||
var sh = fs.Shell({
|
||||
env: {
|
||||
TMP: '/tempdir',
|
||||
PATH: '/one:/two'
|
||||
}
|
||||
});
|
||||
var tempPath = sh.env.get('TMP');
|
||||
sh.env.set('TMP', '/newtempdir');
|
||||
```
|
||||
|
||||
NOTE: unless otherwise stated, all `FileSystemShell` methods can take relative or absolute
|
||||
paths. Relative paths are resolved relative to the shell's current working directory (`sh.cwd`).
|
||||
This is different from the `FileSystem`, which requires absolute paths, and has no notion
|
||||
of a current working directory.
|
||||
|
||||
#### FileSystemShell Properties
|
||||
|
||||
A `FileSystemShell` has a number of properties, including:
|
||||
* `fs` - (readonly) a reference to the bound `FileSystem`
|
||||
* `env` - (readonly) the shell's environment. The shell's environemnt `env` object has `get(name)`
|
||||
and `set(name, value)` methods.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
var fs = new Filer.FileSystem();
|
||||
var sh = fs.Shell();
|
||||
var p = sh.env.get('PATH');
|
||||
|
||||
// Store the current location
|
||||
var before = sh.pwd();
|
||||
var after;
|
||||
sh.cd('/newdir', function(err) {
|
||||
if(err) throw err;
|
||||
// Get the new location
|
||||
after = sh.pwd();
|
||||
});
|
||||
```
|
||||
|
||||
#### FileSystemShell Instance Methods
|
||||
|
||||
Once a `FileSystemShell` object is created, it has the following methods. NOTE: code
|
||||
examples below assume a `FileSystemShell` instance named `sh` has been created like so:
|
||||
|
||||
```javascript
|
||||
var fs = new Filer.FileSystem();
|
||||
var sh = fs.Shell();
|
||||
```
|
||||
|
||||
* [sh.cd(path, callback)](#cd)
|
||||
* [sh.pwd()](#pwd)
|
||||
* [sh.ls(dir, [options], callback)](#ls)
|
||||
* [sh.exec(path, [args], callback)](#exec)
|
||||
* [sh.touch(path, [options], callback)](#touch)
|
||||
* [sh.cat(files, callback)](#cat)
|
||||
* [sh.rm(path, [options], callback)](#rm)
|
||||
* [sh.tempDir(callback)](#tempDir)
|
||||
|
||||
#### sh.cd(path, callback)<a name="cd"></a>
|
||||
|
||||
Changes the current working directory to the directory at `path`. The callback returns
|
||||
an error if `path` does not exist, or is not a directory. Once the callback occurs
|
||||
the shell's cwd is updated to the new path (you can access it via `sh.pwd()`).
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
sh.cd('/dir1', function(err) {
|
||||
if(err) throw err;
|
||||
// sh.pwd() is now '/dir1'
|
||||
});
|
||||
```
|
||||
|
||||
#### sh.pwd()<a name="pwd"></a>
|
||||
|
||||
Returns the shell's current working directory. See [sh.cd()](#cd).
|
||||
|
||||
#### sh.ls(dir, [options], callback)<a name="ls"></a>
|
||||
|
||||
Get the listing of a directory, returning an array of directory entries
|
||||
in the following form:
|
||||
```
|
||||
{
|
||||
path: <String> the basename of the directory entry
|
||||
links: <Number> the number of links to the entry
|
||||
size: <Number> the size in bytes of the entry
|
||||
modified: <Number> the last modified date/time
|
||||
type: <String> the type of the entry
|
||||
contents: <Array> an optional array of child entries, if this entry is itself a directory
|
||||
}
|
||||
```
|
||||
|
||||
By default `sh.ls()` gives a shallow listing. If you want to follow
|
||||
directories as they are encountered, use the `recursive=true` option. NOTE:
|
||||
you should not count on the order of the returned entries always being the same.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
/**
|
||||
* Given a dir structure of:
|
||||
*
|
||||
* /dir
|
||||
* file1
|
||||
* file2
|
||||
* dir2/
|
||||
* file3
|
||||
*/
|
||||
|
||||
// Shallow listing
|
||||
sh.ls('/dir', function(err, entries) {
|
||||
if(err) throw err;
|
||||
// entries is now an array of 3 file/dir entries under /dir
|
||||
});
|
||||
|
||||
// Deep listing
|
||||
sh.ls('/dir', { recursive: true }, function(err, entries) {
|
||||
if(err) throw err;
|
||||
// entries is now an array of 3 file/dir entries under /dir.
|
||||
// The entry object for '/dir2' also includes a `contents` property,
|
||||
// which is an array of 1 entry element for `file3`.
|
||||
});
|
||||
```
|
||||
|
||||
#### sh.exec(path, [args], callback)<a name="exec"></a>
|
||||
|
||||
Attempts to execute the .js command located at `path`. The `sh.exec` method
|
||||
enables apps to install larger programs into the file system and run them
|
||||
later without having to re-download. Such commands should be written so as
|
||||
to assume the existence of 3 global variables, which will be defined at runtime:
|
||||
* `fs` - [FileSystem] the `FileSystem` object bound to this shell.
|
||||
* `args` - [Array] a list of any arguments for the command, or the empty list
|
||||
* `callback` - [Function] a callback function of the form `function callback(error, result)`
|
||||
to call when done.
|
||||
|
||||
The .js command's contents should be the body of a function that
|
||||
looks like this:
|
||||
|
||||
```javascript
|
||||
function(fs, args, callback) {
|
||||
//-------------------------commmand code here---------
|
||||
// ...
|
||||
//----------------------------------------------------
|
||||
}
|
||||
```
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
// Simple command to delete a file.
|
||||
var cmd = "fs.unlink(args[0], callback);"
|
||||
|
||||
// Write the file to the filesystem
|
||||
fs.writeFile('/cmd.js', cmd, callback(err) {
|
||||
if(err) throw err;
|
||||
|
||||
// Execute the command
|
||||
sh.exec('/cmd.js', [ '/file' ], function(err, result) {
|
||||
if(err) throw err;
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
#### sh.touch(path, [options], callback)<a name="touch"></a>
|
||||
|
||||
Create a file if it does not exist, or update the access and modified
|
||||
times if it does. Valid options include:
|
||||
* `updateOnly` - `true` if the file's access/modified dates are to be updated
|
||||
only (but missing file not to be)
|
||||
* `date` - a date to use instead of the current date and time when updating
|
||||
access and modified dates.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
sh.touch('/newfile', function(err) {
|
||||
if(err) throw err;
|
||||
|
||||
fs.exists('/newfile', function(exists) {
|
||||
// exists is now true.
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### sh.cat(files, callback)<a name="cat"></a>
|
||||
|
||||
Concatenates multiple files into a single string, with each file
|
||||
separated by a newline character. The `files` argument should be
|
||||
a String (i.e., path to a single file) or an Array of Strings (i.e.,
|
||||
multiple paths for multiple files).
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
sh.cat([ './file1', '../file2' ], function(err, data) {
|
||||
if(err) throw err;
|
||||
// data is now the contents of file1 and file2 joined
|
||||
});
|
||||
```
|
||||
|
||||
#### sh.rm(path, [options], callback)<a name="rm"></a>
|
||||
|
||||
Removes (deletes) the file or directory at `path`. If `path` is a file, it will
|
||||
be removed. If `path` is a directory, it will be removed if it is empty, otherwise
|
||||
the callback will receive an error. In order to remove non-empty directories,
|
||||
use the `recursive=true` option.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
sh.rm('./file', function(err) {
|
||||
if(err) throw err;
|
||||
// ./file is now removed
|
||||
});
|
||||
|
||||
sh.rm('/dir', { recursive: true }, function(err) {
|
||||
if(err) throw err;
|
||||
// /dir and all its children are now removed
|
||||
});
|
||||
```
|
||||
|
||||
#### sh.tempDir(callback)<a name="tempDir"></a>
|
||||
|
||||
Gets the path to the shell's temporary directory, creating it if it
|
||||
does not already exist. The temp directory to use is specified in the
|
||||
`env.TMP` environment variable. The callback receives an error
|
||||
and the `tempDir` path. NOTE: it is safe to call this many times (i.e.,
|
||||
the temp dir will only be created once). No effort is made to clean-up
|
||||
the temp dir, and it is up to the caller to destroy it if desired.
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
// Default /tmp dir
|
||||
sh.tempDir(function(err, tmp) {
|
||||
if(err) throw err;
|
||||
// tmp is now '/tmp' by default, and /tmp exists
|
||||
});
|
||||
|
||||
// Specify a tmp dir path
|
||||
sh.env.TMP = '/temporary'
|
||||
sh.tempDir(function(err, tmp) {
|
||||
if(err) throw err;
|
||||
// tmp is now '/temporary', and /temporary exists
|
||||
});
|
||||
