# fuse-bindings

Fully maintained fuse bindings for Node that aims to cover the entire FUSE api

```
npm install fuse-bindings
```

Created because [fuse4js](https://github.com/bcle/fuse4js) isn't maintained anymore and doesn't compile on iojs

## Usage

Try creating an empty folder called `mnt` and run the below example

``` js
var fuse = require('fuse-bindings')

fuse.mount('./mnt', {
  readdir: function (path, cb) {
    if (path === '/') return cb(0, ['test'])
    cb(0)
  },
  getattr: function (path, cb) {
    console.log('getattr(%s)', path)
    if (path === '/') {
      cb(0, {
        mtime: new Date(),
        atime: new Date(),
        ctime: new Date(),
        size: 100,
        mode: 16877,
        uid: process.getuid(),
        gid: process.getgid()
      })
      return
    }

    if (path === '/test') {
      cb(0, {
        mtime: new Date(),
        atime: new Date(),
        ctime: new Date(),
        size: 12,
        mode: 33188,
        uid: process.getuid(),
        gid: process.getgid()
      })
      return
    }

    cb(fuse.ENOENT)
  },
  open: function (path, flags, cb) {
    console.log('open(%s, %d)', path, flags)
    cb(0, 42) // 42 is an fd
  },
  read: function (path, fd, buf, len, pos, cb) {
    console.log('read(%s, %d, %d, %d)', path, fd, len, pos)
    var str = 'hello world\n'.slice(pos)
    if (!str) return cb(0)
    buf.write(str)
    return cb(str.length)
  }
})

process.on('SIGINT', function () {
  fuse.unmount('./mnt', function () {
    process.exit()
  })
})
```

## API

#### `fuse.mount(mnt, ops)`

Mount a new filesystem on `mnt`.
Pass the FUSE operations you want to support as the `ops` argument.

#### `fuse.unmount(mnt, [cb])`

Unmount a filesystem

#### `fuse.unmountSync(mnt)`

Unmount a filesystem synchroniously

## FUSE operations

Most of the [FUSE api](http://fuse.sourceforge.net/doxygen/structfuse__operations.html) is supported.

* `ops.init(cb)`
* `ops.access(path, cb)`
* `ops.statfs(path, cb)`
* `ops.getattr(path, cb)`
* `ops.fgetattr(path, fd, cb)`
* `ops.flush(path, fd, cb)`
* `ops.fsync(path, fd, cb)`
* `ops.fsyncdir(path, fd, cb)`
* `ops.readdir(path, cb)`
* `ops.truncate(path, size, cb)`
* `ops.ftruncate(path, fd, size, cb)`
* `ops.readlink(path, result, cb)`
* `ops.chown(path, uid, gid, cb)`
* `ops.chmod(path, mode, cb)`
* `ops.setxattr(path, name, buf, length, offset, flags, cb)`
* `ops.getxattr(path, name, buf, length, offset, cb)`
* `ops.open(path, flags, cb)`
* `ops.opendir(path, flags, cb)`
* `ops.read(path, fd, buf, length, position, cb)`
* `ops.write(path, fd, buf, length, position, cb)`
* `ops.release(path, fd, cb)`
* `ops.releasedir(path, fd, cb)`
* `ops.create(path, mode, cb)`
* `ops.utimens(path, cb)`
* `ops.unlink(path, cb)`
* `ops.rename(src, dest, cb)`
* `ops.link(src, dest, cb)`
* `ops.symlink(src, dest, cb)`
* `ops.mkdir(path, cb)`
* `ops.rmdir(path, cb)`
* `ops.destroy(cb)`

The goal is to support 100% of the API.

When using `getattr` you should return a stat object after the status code,
`readdir` expects an array of directory names, `open` an optional fd and
`utimens` an object with `mtime` and `atime` dates.

Both `read` and `write` passes the underlying fuse buffer without copying them to be as fast as possible.

You can pass [mount options](http://blog.woralelandia.com/2012/07/16/fuse-mount-options/) (i.e. `direct_io` etc) as `ops.options = ['direct_io']`
