Sectioned Fs
This package implements an afero.Fs
with directories at the root mapped by strings to other afero.Fs's.
The interface adds two

Overview ¶
Package sectionedfs implements an afero.Fs filesystem in which immediate subdirectories are named by strings mapped to other afero.Fs filesystems. You can combine disparate directories from multiple filesystems into what is accessed as a single directory.

Types ¶
type Fs ¶
Fs implements the afero.Fs interface for a group of named afero.Fs's. Each sub-Fs is accessed via the first element of the paths given to Fs
Example ¶
package main
import (
"fmt"
"io/ioutil"
"github.com/spf13/afero"
"gitlab.com/tbhartman/sectionedfs"
)
func main() {
a := afero.NewMemMapFs()
b := afero.NewMemMapFs()
parentFs := sectionedfs.New()
parentFs.RegisterSection("a", a)
parentFs.RegisterSection("b", b)
fs := parentFs.(afero.Fs)
fs.MkdirAll("a/dir_under_a", 0700)
fs.MkdirAll("b/dir_under_b", 0700)
fa, _ := fs.Create("a/dir_under_a/file_in_a")
fa.WriteString("sample text\n")
fa.Close()
fileViaChild, _ := a.Open("dir_under_a/file_in_a")
contents, _ := ioutil.ReadAll(fileViaChild)
fmt.Print(string(contents))
}
Output: sample text
