LanguageDirsMerger implements the afero.DirsMerger interface, which is used to merge two directories.

Functions

func DecorateBasePathFs added in v0.56.0 

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 added in v0.57.0 

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 MakeReadableAndRemoveAllModulePkgDir added in v0.65.0 

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 added in v0.56.0 

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 added in v0.55.0 

func NewCreateCountingFs(fs afero.Fs) afero.Fs

func NewFilterFs added in v0.56.0 

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

func NewHashingFs added in v0.45.1 

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 NewLanguageCompositeFs added in v0.38.1 

func NewLanguageCompositeFs(base, overlay afero.Fs) afero.Fs

NewLanguageCompositeFs creates a composite and language aware filesystem. This is a hybrid filesystem. To get a specific file in Open, Stat etc., use the full filename to the target filesystem. This information is available in Readdir, Stat etc. via the special LanguageFileInfo FileInfo implementation.

func NewLanguageFs added in v0.38.1 

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

func NewNoSymlinkFs added in v0.56.0 

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

NewNoSymlinkFs creates a new filesystem that prevents symlinks.

func NewSliceFs added in v0.56.0 

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

func NewStacktracerFs added in v0.55.0 

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.
