# Go-FUSE
[](https://github.com/hanwen/go-fuse/actions/workflows/ci.yml)
[](https://godoc.org/github.com/hanwen/go-fuse/v2/fs)
Go native bindings for the FUSE kernel module.
Use
[github.com/hanwen/go-fuse/v2/fs](https://godoc.org/github.com/hanwen/go-fuse/v2/fs)
library. It follows the wire protocol closely, but provides
convenient abstractions for building both node and path based file
systems
## Release notes
v2.8
* fuse, fs: support IOCTL
* fuse: add RawFileSystem.OnUnmount
* fs: symlink safety for fs.LoopbackRoot
* fuse: ID mapped mounts
* fs: NewLoopbackDirStreamFd
v2.7
* fuse, fs: support STATX
v2.6
* general:
* drop support for go1.16
* fuse:
* FreeBSD support
* passthrough support for increased performance
* DirEntryList.Offset and DirEntry.Off are visible now; add DirEntry.Parse
* fs:
* new directory API, supporting caching and file handles for Readdir and FsyncDir
* passthrough support for increased performance
* allow LoopbackNode to be used as non-root
* OnForget method
v2.5
* Support for RenameExchange on Darwin
## Comparison with other FUSE libraries
Further highlights of this library is
* Comprehensive and up to date protocol support (up to 7.12.28).
* Performance that is competitive with libfuse.
## Examples
* [example/hello/](example/hello/main.go) contains a 60-line "hello world" filesystem
* [zipfs/zipfs](zipfs/zipfs.go) contains a small and simple read-only filesystem for
zip and tar files. The corresponding command is in example/zipfs/
For example,
```shell
mkdir /tmp/mountpoint
example/zipfs/zipfs /tmp/mountpoint file.zip &
ls /tmp/mountpoint
fusermount -u /tmp/mountpoint
````
* [zipfs/multizipfs](zipfs/multizipfs.go) shows how to use combine
simple Go-FUSE filesystems into a larger filesystem.
* [example/loopback](example/loopback/main.go) mounts another piece of the filesystem.
Functionally, it is similar to a symlink. A binary to run is in
example/loopback/ . For example
```shell
mkdir /tmp/mountpoint
example/loopback/loopback -debug /tmp/mountpoint /some/other/directory &
ls /tmp/mountpoint
fusermount -u /tmp/mountpoint
```
## macOS Support
The main developer (hanwen@) does not own a Mac to test, but accepts
patches to make Go-FUSE work on Mac.
* All of the limitations of OSXFUSE, including lack of support for
NOTIFY.
* OSX issues STATFS calls continuously (leading to performance
concerns).
* OSX has trouble with concurrent reads from the FUSE device, leading
to performance concerns.
* Tests are expected to pass; report any failure as a bug!

## Bugs
Report them through https://github.com/hanwen/go-fuse/issues. Please
include a debug trace (set `fuse.MountOptions.Debug` to `true`).
