vfscopy

Recursively copy a Virtual FileSystem, such as http.FileSystem, to a native file system destination.

Works with any file system that implements http.FileSystem, including vfsgen, fileb0x, gobindata and most others.

GoDoc

See https://pkg.go.dev/git.rootprojects.org/root/vfscopy.

Examples

(Native) File System

httpfs := http.Dir("/tmp/public/")
vfs := vfscopy.NewVFS(httpfs)

if err := vfscopy.CopyAll(vfs, ".", "/tmp/dst/"); nil != err {
    fmt.Fprintf(os.Stderr, "couldn't copy vfs: %v\n", err)
}

vfsgen (http.FileSystem)

Note: vfsgen does not support symlinks or file permissions.

package main

import (
    "fmt"

    "git.rootprojects.org/root/vfscopy"

    // vfsgen-generated file system
    "git.example.com/org/project/assets"
)

func main() {
    vfs := vfscopy.NewVFS(assets.Assets)

    if err := vfscopy.CopyAll(vfs, ".", "/tmp/dst/"); nil != err {
        fmt.Fprintf(os.Stderr, "couldn't copy vfs: %v\n", err)
    }
    fmt.Println("Done.")
}

Test

# Generate the test virtual file system
go generate ./...

# Run the tests
go test ./...
