embed.FS wrapper providing additional functionality
- Get an
embed.FSfrom an embedded subdirectory - Handy
Copy(sourcePath, targetPath)method to copy an embedded file to the filesystem - 100%
embed.FScompatible - 100% code coverage
package main import ( "embed" "github.com/leaanthony/debme" "io/fs" ) // Example Filesystem: // // fixtures/ // ├── test1 // | └── onefile.txt // └── test2 // └── inner // ├── deeper // | └── three.txt // ├── one.txt // └── two.txt //go:embed fixtures var fixtures embed.FS func main() { root, _ := debme.FS(fixtures, "fixtures") // Anchor to "fixtures/test1" test1, _ := root.FS("test1") files1, _ := test1.ReadDir(".") println(len(files1)) // 1 println(files1[0].Name()) // "onefile.txt" // Anchor to "fixtures/test2/inner" inner, _ := root.FS("test2/inner") one, _ := inner.ReadFile("one.txt") println(string(one)) // "1" // Fully compatible FS fs.WalkDir(inner, ".", func(path string, d fs.DirEntry, err error) error { if err != nil { return err } println("Path:", path, " Name:", d.Name()) return nil }) /* Path: . Name: inner Path: deeper Name: deeper Path: deeper/three.txt Name: three.txt Path: one.txt Name: one.txt Path: two.txt Name: two.txt */ // Go deeper deeper, _ := inner.FS("deeper") deeperFiles, _ := deeper.ReadDir(".") println(len(deeperFiles)) // 1 println(files1[0].Name()) // "three.txt" // Copy files err := deeper.Copy("three.txt", "/path/to/target.txt") }Go's new embed functionality is awesome! The only thing I found a little frustrating was the need to manage base paths. This module was created out of the need to embed multiple templates in the Wails CLI.
