# WORK IN PROGRESS

This is a demo/toy program to test the implementation and performance of

the [net/styx](https://aqwari.net/net/styx) package, which itself is a

work in progress. If you are having trouble getting things to work, ensure

you have checked out the latest version of the `aqwari.net/net/styx`

package.

# BUILD

	go build

# USE

Start jsonfs on port 5640:

	./jsonfs -a localhost:5640 example.json

Using plan9port's `9pfuse` utility, mount the fs:

	9pfuse localhost:5640 /mnt/jsonfs

If you have a recent (2.6+) linux kernel, you can

mount using the kernel's `v9fs` implementation.

Unfortunately you'll need root access to do so

without modifying `/etc/fstab`:

	sudo modprobe 9p

	sudo mount -t 9p -o \

		tcp,name=`whoami`,uname=`whoami`,port=5640 \

		127.0.0.1 /mnt/jsonfs

	

Try looking around

	$ ls /mnt/jsonfs

	apiVersion data

	$ cat /mnt/jsonfs/apiVersion

	2.0

You should see output from jsonfs, such as

	accepted connection from 127.0.0.1:36602

	→ 65535 Tversion msize=8192 version="9P2000"

	← 65535 Rversion msize=8192 version="9P2000"

	→ 000 Tattach fid=1 afid=NOFID uname="droyo" aname=""

	← 000 Rattach qid="type=128 ver=0 path=1"

	→ 000 Twalk fid=1 newfid=2 "apiVersion"

	← 000 Rwalk wqid="type=0 ver=0 path=2"

	→ 000 Topen fid=2 mode=0

	← 000 Ropen qid="type=0 ver=0 path=2" iounit=0

	→ 000 Tread fid=2 offset=0 count=8168

	← 000 Rread count=3

	→ 000 Tread fid=2 offset=3 count=8168

	← 000 Rread count=0

When using example.json, the tree hierarchy should look

something like this:

	$ tree /mnt/jsonfs

	/mnt/jsonfs
