Afero has an exceptionally clean interface and simple design -without needless constructors or initialization methods. - -Afero is also a library providing a base set of interoperable backend -filesystems that make it easy to work with afero while retaining all the power -and benefit of the os and ioutil packages. - -Afero provides significant improvements over using the os package alone, most -notably the ability to create mock and testing filesystems without relying on the disk. - -It is suitable for use in a any situation where you would consider using the OS -package as it provides an additional abstraction that makes it easy to use a -memory backed file system during testing. It also adds support for the http -filesystem for full interoperability. - - -## Afero Features - -* A single consistent API for accessing a variety of filesystems -* Interoperation between a variety of file system types -* A set of interfaces to encourage and enforce interoperability between backends -* An atomic cross platform memory backed file system -* Support for compositional (union) file systems by combining multiple file systems acting as one -* Specialized backends which modify existing filesystems (Read Only, Regexp filtered) -* A set of utility functions ported from io, ioutil & hugo to be afero aware - - -# Using Afero - -Afero is easy to use and easier to adopt. - -A few different ways you could use Afero: - -* Use the interfaces alone to define you own file system. -* Wrap for the OS packages. -* Define different filesystems for different parts of your application. -* Use Afero for mock filesystems while testing - -## Step 1: Install Afero - -First use go get to install the latest version of the library. - - $ go get github.com/spf13/afero - -Next include Afero in your application. -```go -import "github.com/spf13/afero" -``` - -## Step 2: Declare a backend - -First define a package variable and set it to a pointer to a filesystem. -```go -var AppFs = afero.NewMemMapFs() - -or - -var AppFs = afero.NewOsFs() -``` -It is important to note that if you repeat the composite literal you -will be using a completely new and isolated filesystem. In the case of -OsFs it will still use the same underlying filesystem but will reduce -the ability to drop in other filesystems as desired. - -## Step 3: Use it like you would the OS package - -Throughout your application use any function and method like you normally -would. - -So if my application before had: -```go -os.Open('/tmp/foo') -``` -We would replace it with: -```go -AppFs.Open('/tmp/foo') -``` - -`AppFs` being the variable we defined above. - - -## List of all available functions - -File System Methods Available: -```go -Chmod(name string, mode os.FileMode) : error -Chtimes(name string, atime time.Time, mtime time.Time) : error -Create(name string) : File, error -Mkdir(name string, perm os.FileMode) : error -MkdirAll(path string, perm os.FileMode) : error -Name() : string -Open(name string) : File, error -OpenFile(name string, flag int, perm os.FileMode) : File, error -Remove(name string) : error -RemoveAll(path string) : error -Rename(oldname, newname string) : error -Stat(name string) : os.FileInfo, error -``` -File Interfaces and Methods Available: -```go -io.Closer -io.Reader -io.ReaderAt -io.Seeker -io.Writer -io.WriterAt - -Name() : string -Readdir(count int) : []os.FileInfo, error -Readdirnames(n int) : []string, error -Stat() : os.FileInfo, error -Sync() : error -Truncate(size int64) : error -WriteString(s string) : ret int, err error -``` -In some applications it may make sense to define a new package that -simply exports the file system variable for easy access from anywhere. - -## Using Afero's utility functions - -Afero provides a set of functions to make it easier to use the underlying file systems. -These functions have been primarily ported from io & ioutil with some developed for Hugo. - -The afero utilities support all afero compatible backends. - -The list of utilities includes: - -```go -DirExists(path string) (bool, error) -Exists(path string) (bool, error) -FileContainsBytes(filename string, subslice []byte) (bool, error) -GetTempDir(subPath string) string -IsDir(path string) (bool, error) -IsEmpty(path string) (bool, error) -ReadDir(dirname string) ([]os.FileInfo, error) -ReadFile(filename string) ([]byte, error) -SafeWriteReader(path string, r io.Reader) (err error) -TempDir(dir, prefix string) (name string, err error) -TempFile(dir, prefix string) (f File, err error) -Walk(root string, walkFn filepath.WalkFunc) error -WriteFile(filename string, data []byte, perm os.FileMode) error -WriteReader(path string, r io.Reader) (err error) -``` -For a complete list see [Afero's GoDoc](https://godoc.org/github.com/spf13/afero) - -They are available under two different approaches to use. You can either call -them directly where the first parameter of each function will be the file -system, or you can declare a new `Afero`, a custom type used to bind these -functions as methods to a given filesystem. - -### Calling utilities directly - -```go -fs := new(afero.MemMapFs) -f, err := afero.TempFile(fs,"", "ioutil-test") - -``` - -### Calling via Afero - -```go -fs := afero.NewMemMapFs() -afs := &afero.Afero{Fs: fs} -f, err := afs.TempFile("", "ioutil-test") -``` - -## Using Afero for Testing - -There is a large benefit to using a mock filesystem for testing. It has a -completely blank state every time it is initialized and can be easily -reproducible regardless of OS. You could create files to your heart’s content -and the file access would be fast while also saving you from all the annoying -issues with deleting temporary files, Windows file locking, etc. The MemMapFs -backend is perfect for testing. - -* Much faster than performing I/O operations on disk -* Avoid security issues and permissions -* Far more control. 'rm -rf /' with confidence -* Test setup is far more easier to do -* No test cleanup needed - -One way to accomplish this is to define a variable as mentioned above. -In your application this will be set to afero.NewOsFs() during testing you -can set it to afero.NewMemMapFs(). - -It wouldn't be uncommon to have each test initialize a blank slate memory -backend. To do this I would define my `appFS = afero.NewOsFs()` somewhere -appropriate in my application code. This approach ensures that Tests are order -independent, with no test relying on the state left by an earlier test. - -Then in my tests I would initialize a new MemMapFs for each test: -```go -func TestExist(t *testing.T) { - appFS := afero.NewMemMapFs() - // create test files and directories - appFS.MkdirAll("src/a", 0755) - afero.WriteFile(appFS, "src/a/b", []byte("file b"), 0644) - afero.WriteFile(appFS, "src/c", []byte("file c"), 0644) - name := "src/c" - _, err := appFS.Stat(name) - if os.IsNotExist(err) { - t.Errorf("file \"%s\" does not exist.\n", name) - } -} -``` - -# Available Backends - -## Operating System Native - -### OsFs - -The first is simply a wrapper around the native OS calls. This makes it -very easy to use as all of the calls are the same as the existing OS -calls. It also makes it trivial to have your code use the OS during -operation and a mock filesystem during testing or as needed. - -```go -appfs := afero.NewOsFs() -appfs.MkdirAll("src/a", 0755)) -``` - -## Memory Backed Storage - -### MemMapFs - -Afero also provides a fully atomic memory backed filesystem perfect for use in -mocking and to speed up unnecessary disk io when persistence isn’t -necessary. It is fully concurrent and will work within go routines -safely. - -```go -mm := afero.NewMemMapFs() -mm.MkdirAll("src/a", 0755)) -``` - -#### InMemoryFile - -As part of MemMapFs, Afero also provides an atomic, fully concurrent memory -backed file implementation. This can be used in other memory backed file -systems with ease. Plans are to add a radix tree memory stored file -system using InMemoryFile. - -## Network Interfaces - -### SftpFs - -Afero has experimental support for secure file transfer protocol (sftp). Which can -be used to perform file operations over a encrypted channel. - -## Filtering Backends - -### BasePathFs - -The BasePathFs restricts all operations to a given path within an Fs. -The given file name to the operations on this Fs will be prepended with -the base path before calling the source Fs. - -```go -bp := afero.NewBasePathFs(afero.NewOsFs(), "/base/path") -``` - -### ReadOnlyFs - -A thin wrapper around the source Fs providing a read only view. - -```go -fs := afero.NewReadOnlyFs(afero.NewOsFs()) -_, err := fs.Create("/file.txt") -// err = syscall.EPERM -``` - -# RegexpFs - -A filtered view on file names, any file NOT matching -the passed regexp will be treated as non-existing. -Files not matching the regexp provided will not be created. -Directories are not filtered. - -```go -fs := afero.NewRegexpFs(afero.NewMemMapFs(), regexp.MustCompile(`\.txt$`)) -_, err := fs.Create("/file.html") -// err = syscall.ENOENT -``` - -### HttpFs - -Afero provides an http compatible backend which can wrap any of the existing -backends. - -The Http package requires a slightly specific version of Open which -returns an http.File type. - -Afero provides an httpFs file system which satisfies this requirement. -Any Afero FileSystem can be used as an httpFs. - -```go -httpFs := afero.NewHttpFs(<ExistingFS>) -fileserver := http.FileServer(httpFs.Dir(<PATH>))) -http.Handle("/", fileserver) -``` - -## Composite Backends - -Afero provides the ability have two filesystems (or more) act as a single -file system. - -### CacheOnReadFs - -The CacheOnReadFs will lazily make copies of any accessed files from the base -layer into the overlay. Subsequent reads will be pulled from the overlay -directly permitting the request is within the cache duration of when it was -created in the overlay. - -If the base filesystem is writeable, any changes to files will be -done first to the base, then to the overlay layer. Write calls to open file -handles like `Write()` or `Truncate()` to the overlay first. - -To writing files to the overlay only, you can use the overlay Fs directly (not -via the union Fs). - -Cache files in the layer for the given time.Duration, a cache duration of 0 -means "forever" meaning the file will not be re-requested from the base ever. - -A read-only base will make the overlay also read-only but still copy files -from the base to the overlay when they're not present (or outdated) in the -caching layer. - -```go -base := afero.NewOsFs() -layer := afero.NewMemMapFs() -ufs := afero.NewCacheOnReadFs(base, layer, 100 * time.Second) -``` - -### CopyOnWriteFs() - -The CopyOnWriteFs is a read only base file system with a potentially -writeable layer on top. - -Read operations will first look in the overlay and if not found there, will -serve the file from the base. - -Changes to the file system will only be made in the overlay. - -Any attempt to modify a file found only in the base will copy the file to the -overlay layer before modification (including opening a file with a writable -handle). - -Removing and Renaming files present only in the base layer is not currently -permitted. If a file is present in the base layer and the overlay, only the -overlay will be removed/renamed. - -```go - base := afero.NewOsFs() - roBase := afero.NewReadOnlyFs(base) - ufs := afero.NewCopyOnWriteFs(roBase, afero.NewMemMapFs()) - - fh, _ = ufs.Create("/home/test/file2.txt") - fh.WriteString("This is a test") - fh.Close() -``` - -In this example all write operations will only occur in memory (MemMapFs) -leaving the base filesystem (OsFs) untouched. - - -## Desired/possible backends - -The following is a short list of possible backends we hope someone will -implement: - -* SSH -* ZIP -* TAR -* S3 - -# About the project - -## What's in the name - -Afero comes from the latin roots Ad-Facere. - -**"Ad"** is a prefix meaning "to". - -**"Facere"** is a form of the root "faciō" making "make or do". - -The literal meaning of afero is "to make" or "to do" which seems very fitting -for a library that allows one to make files and directories and do things with them. - -The English word that shares the same roots as Afero is "affair". Affair shares -the same concept but as a noun it means "something that is made or done" or "an -object of a particular type". - -It's also nice that unlike some of my other libraries (hugo, cobra, viper) it -Googles very well. - -## Release Notes - -* **0.10.0** 2015.12.10 - * Full compatibility with Windows - * Introduction of afero utilities - * Test suite rewritten to work cross platform - * Normalize paths for MemMapFs - * Adding Sync to the file interface - * **Breaking Change** Walk and ReadDir have changed parameter order - * Moving types used by MemMapFs to a subpackage - * General bugfixes and improvements -* **0.9.0** 2015.11.05 - * New Walk function similar to filepath.Walk - * MemMapFs.OpenFile handles O_CREATE, O_APPEND, O_TRUNC - * MemMapFs.Remove now really deletes the file - * InMemoryFile.Readdir and Readdirnames work correctly - * InMemoryFile functions lock it for concurrent access - * Test suite improvements -* **0.8.0** 2014.10.28 - * First public version - * Interfaces feel ready for people to build using - * Interfaces satisfy all known uses - * MemMapFs passes the majority of the OS test suite - * OsFs passes the majority of the OS test suite - -## Contributing - -1.
