# go-billy [](https://pkg.go.dev/github.com/go-git/go-billy/v5) [](https://github.com/go-git/go-billy/actions?query=workflow%3ATest)
|
|
|
|
The missing interface filesystem abstraction for Go.
|
|
Billy implements an interface based on the `os` standard library, allowing to develop applications without dependency on the underlying storage. Makes it virtually free to implement mocks and testing over filesystem operations.
|
|
|
|
Billy was born as part of [go-git/go-git](https://github.com/go-git/go-git) project.
|
|
|
|
## Installation
|
|
|
|
```go
|
|
import "github.com/go-git/go-billy/v5" // with go modules enabled (GO111MODULE=on or outside GOPATH)
|
|
import "github.com/go-git/go-billy" // with go modules disabled
|
|
```
|
|
|
|
## Usage
|
|
|
|
Billy exposes filesystems using the
|
|
[`Filesystem` interface](https://pkg.go.dev/github.com/go-git/go-billy/v5?tab=doc#Filesystem).
|
|
Each filesystem implementation gives you a `New` method, whose arguments depend on
|
|
the implementation itself, that returns a new `Filesystem`.
|
|
|
|
The following example caches in memory all readable files in a directory from any
|
|
billy's filesystem implementation.
|
|
|
|
```go
|
|
func LoadToMemory(origin billy.Filesystem, path string) (*memory.Memory, error) {
|
|
memory := memory.New()
|
|
|
|
files, err := origin.ReadDir("/")
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
|
|
for _, file := range files {
|
|
if file.IsDir() {
|
|
continue
|
|
}
|
|
|
|
src, err := origin.Open(file.Name())
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
|
|
dst, err := memory.Create(file.Name())
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
|
|
if _, err = io.Copy(dst, src); err != nil {
|
|
return nil, err
|
|
}
|
|
|
|
if err := dst.Close(); err != nil {
|
|
return nil, err
|
|
}
|
|
|
|
if err := src.Close(); err != nil {
|
|
return nil, err
|
|
}
|
|
}
|
|
|
|
return memory, nil
|
|
}
|
|
```
|
|
|
|
## Why billy?
|
|
|
|
The library billy deals with storage systems and Billy is the name of a well-known, IKEA
|
|
bookcase. That's it.
