Document how to read squashfs files

[probonopd]

Hi, thanks for this very useful library. Could you please document how to read squashfs files and print the files, directories, and symlinks contained therein; e.g., is the following halfway right?

package main

import (
	"log"
	"os"

	"github.com/diskfs/go-diskfs/filesystem/squashfs" // Have to use: GO111MODULE=on /usr/local/go/bin/go get github.com/diskfs/go-diskfs@squashfs
)

func main() {
	f, err := os.Open("/home/me/go/src/github.com/diskfs/go-diskfs/filesystem/squashfs/testdata/file.sqs")
	if err != nil {
		log.Println(err)
	}
	defer f.Close()
	fs, err := squashfs.Read(f, 0, 0, 4096)
	if err != nil {
		log.Println(err)
	}
	files, err := fs.ReadDir("/") // How to list all contents including subdirectories?
	for f := range files {
		print(f)
	}
}

Reading any filesystem is identical. One of the key points of the lib is to abstract it all. So it almost is it, but not quite.

package main

import (
	"log"
	"os"

	diskfs "github.com/diskfs/go-diskfs" 
)

func main() {
	disk, err := diskfs.Open("/home/me/go/src/github.com/diskfs/go-diskfs/filesystem/squashfs/testdata/file.sqs")
	if err != nil {
		log.Panic(err)
	}
	fs, err := disk.GetFilesystem(0) // assuming it is the whole disk, so partition = 0
	if err != nil {
		log.Panic(err)
	}
	files, err := fs.ReadDir("/") // this should list everything
}

We probably should document this, so keep it open.

Thanks for the example @deitch however it does not compile for me:

me@host:~$ /usr/local/go/bin/go build test.go 
# github.com/diskfs/go-diskfs/partition/gpt
go/src/github.com/diskfs/go-diskfs/partition/gpt/partiton.go:218:8: assignment mismatch: 1 variable but uuid.NewV4 returns 2 values
go/src/github.com/diskfs/go-diskfs/partition/gpt/table.go:82:22: multiple-value uuid.NewV4() in single-value context
go/src/github.com/diskfs/go-diskfs/partition/gpt/table.go:283:8: assignment mismatch: 1 variable but uuid.NewV4 returns 2 values

Yeah it’s just sample code. Not really runnable.
