gitfuse

A CLI tool that mounts js-git repos as local filesystems using fuse4js.

Examples

Mounting a local bare git repo.

# Create a local bare repo by cloning a remote 
> git clone --bare [e-mail]:creationix/conquest.git
# Create a mountpoint 
> mkdir conquest
# mount with some custom fuse options 
# the `auto_umount` option is linux only. 
> gitfuse -p conquest.git -m conquest -o allow_other,auto_umount

Mounting a remote github repo using Github's REST API. Create a token at https://github.com/settings/tokens/new.

# Paste in your own token 
> export GITHUB_TOKEN=a19e1bbf332ef7937a54c5f3de47b2813b27be42
# Create a mountpoint 
> mkdir exploder
# Mount it! 
> gitfuse -g creationix/exploder -p exploder -o allow_other

In either example, the fuse command blocks the terminal, so either background with & or open a new terminal tab to test the mount.

To umount either use sudo umount /path/to/mountpoint or use fusermount -u /path/to/mountpoint.

Setup

This currently uses a C++ node addon to communicate with the fuse kernel module. This is the fuse4js Project. You need to first install the dependencies for it before you can npm install -g gitfuse.

On linux, install the fuse dev headers and the fuse package.
For ubuntu this is apt-get install fuse libfuse-dev.
On OSX, I recommend installing http://osxfuse.github.io/.

Also There is a V8 bug in node v0.10.31 that causes segfaults when inflating the git data in js-git and fuse4js doesn't work yet in node v0.11.x so I recommend you use nvm to make sure you're running node v0.10.30.

Installing

Once you have the fuse headers and userspace tools (fusermount) installed, you can install gitfuse.

> npm install -g gitfuse

Then have fun!

TODO

Currently this only mounts the git repo read-only. In the future it will allow also writing to the repo and creating new commits.
