LanguageDirsMerger implements the overlayfs.DirsMerger func, which is used to merge two directories.

	// NoOpFs provides a no-op filesystem that implements the afero.Fs

var Os = &afero.OsFs{}

Os points to the (real) Os filesystem.

Functions

func DecorateBasePathFs 

func DecorateBasePathFs(base *afero.BasePathFs) afero.Fs

DecorateBasePathFs adds Path info to files and directories in the provided BasePathFs, using the base as base.

func Glob 

func Glob(fs afero.Fs, pattern string, handle func(fi FileMetaInfo) (bool, error)) error

Glob walks the fs and passes all matches to the handle func. The handle func can return true to signal a stop.

func IsOsFs 

func IsOsFs(fs afero.Fs) bool

IsOsFs returns whether fs is an OsFs or if it fs wraps an OsFs. TODO(bep) make this more robust.

func MakeReadableAndRemoveAllModulePkgDir 

func MakeReadableAndRemoveAllModulePkgDir(fs afero.Fs, dir string) (int, error)

MakeReadableAndRemoveAllModulePkgDir makes any subdir in dir readable and then removes the root. TODO(bep) move this to a more suitable place.

func NewBaseFileDecorator 

func NewBaseFileDecorator(fs afero.Fs, callbacks ...func(fi FileMetaInfo)) afero.Fs

NewBaseFileDecorator decorates the given Fs to provide the real filename and an Opener func.

func NewCreateCountingFs 

func NewCreateCountingFs(fs afero.Fs) afero.Fs

func NewFilterFs 

func NewFilterFs(fs afero.Fs) (afero.Fs, error)

func NewHasBytesReceiver 

func NewHasBytesReceiver(delegate afero.Fs, shouldCheck func(name string) bool, hasBytesCallback func(name string, match bool), pattern []byte) afero.Fs

func NewHashingFs 

func NewHashingFs(delegate afero.Fs, hashReceiver FileHashReceiver) afero.Fs

NewHashingFs creates a new filesystem that will receive MD5 checksums of any written file content on Close. Note that this is probably not a good idea for "full build" situations, but when doing fast render mode, the amount of files published is low, and it would be really nice to know exactly which of these files where actually changed. Note that this will only work for file operations that use the io.Writer to write content to file, but that is fine for the "publish content" use case.

func NewLanguageFs 

func NewLanguageFs(langs map[string]int, fs afero.Fs) (afero.Fs, error)

func NewNoSymlinkFs 

func NewNoSymlinkFs(fs afero.Fs, logger loggers.Logger, allowFiles bool) afero.Fs

NewNoSymlinkFs creates a new filesystem that prevents symlinks.

func NewSliceFs 

func NewSliceFs(dirs ...FileMetaInfo) (afero.Fs, error)

func NewStacktracerFs 

func NewStacktracerFs(fs afero.Fs, pattern string) afero.Fs

NewStacktracerFs wraps the given fs printing stack traces for file creates matching the given regexp pattern.

func WalkFilesystems 

func WalkFilesystems(fs afero.Fs, fn WalkFn) bool

WalkFilesystems walks fs recursively and calls fn. If fn returns true, walking is stopped.
