Cross-platform FUSE library for Go

Travis CI AppVeyor CircleCI GoDoc

Cgofuse is a cross-platform FUSE library for Go. It is implemented using cgo and can be ported to any platform that has a FUSE implementation.

Cgofuse currently runs on OSX, Linux and Windows (using WinFsp).

How to build

OSX

  • Prerequisites: OSXFUSE, command line tools
  • Build: 
    $ cd cgofuse
$ go install -v ./fuse ./examples/memfs ./examples/passthrough

Linux

  • Prerequisites: libfuse-dev, gcc
  • Build: 
    $ cd cgofuse
$ go install -v ./fuse ./examples/memfs ./examples/passthrough

Windows

  • Prerequisites: WinFsp, gcc (e.g. from Mingw-builds)
  • Build: 
    > cd cgofuse
> set CPATH=C:\Program Files (x86)\WinFsp\inc\fuse
> go install -v ./fuse ./examples/memfs

How to cross-compile your project using xgo

You can easily cross-compile your project using xgo and the billziss/xgo-cgofuse docker image.

  • Prerequisites: docker, xgo
  • Build: 
    $ docker pull billziss/xgo-cgofuse
$ go get -u github.com/karalabe/xgo
$ cd YOUR-PROJECT-THAT-USES-CGOFUSE
$ xgo --image=billziss/xgo-cgofuse \
    --targets=darwin/386,darwin/amd64,linux/386,linux/amd64,windows/386,windows/amd64 .

How to use

User mode file systems are expected to implement fuse.FileSystemInterface. To make implementation simpler a file system can embed ("inherit") a fuse.FileSystemBase which provides default implementations for all operations. To mount a file system one must instantiate a fuse.FileSystemHost using fuse.NewFileSystemHost.

The full documentation is available at GoDoc.org: package fuse

There are currently three example file systems:

  • Hellofs is an extremely simple file system. Runs on OSX, Linux and Windows.
  • Memfs is an in memory file system. Runs on OSX, Linux and Windows.
  • Passthrough is a file system that passes all operations to the underlying file system. Runs on OSX, Linux.

How it is tested

Cgofuse is regularly built and tested on Travis CI and AppVeyor. The following software is being used to test cgofuse.

OSX/Linux

Windows
