Functions

func WithFlags

func WithFlags(flags int) jsfs.OFOption

WithFlags sets the flags based on package "os" flag values. By default this is O_RDONLY.

Types

type FS

type FS struct{}

FS implemements fs.ReadDirFS/StatFS/ReadFileFS/GlobFS using functions defined in the "os" and "filepath" packages. In addition we support github.com/johnsiilver/fs/OpenFiler to allow for writing files.

func (*FS) Glob

func (f *FS) Glob(pattern string) (matches []string, err error)

Glob implements fs.GlobFS.Glob().

func (*FS) Open

func (f *FS) Open(name string) (fs.File, error)

Open implements fs.FS.Open().

func (*FS) OpenFile

func (f *FS) OpenFile(name string, perms fs.FileMode, options ...jsfs.OFOption) (fs.File, error)

OpenFile opens a file with the set flags and fs.FileMode. If you want to use the fs.File to write, you need to type assert if to *os.File. If Opening a file for

func (*FS) ReadDir

func (f *FS) ReadDir(name string) ([]fs.DirEntry, error)

ReadDir implements fs.ReadDirFS.ReadDir().

func (*FS) ReadFile

func (f *FS) ReadFile(name string) ([]byte, error)

ReadFile implements fs.ReadFileFS.ReadFile().

func (*FS) Stat

func (f *FS) Stat(name string) (fs.FileInfo, error)

Stat implememnts fs.StatFS.Stat().

func (*FS) WriteFile

func (f *FS) WriteFile(name string, content []byte, perm fs.FileMode) error

WriteFile implements jsfs.Writer.WriteFile(). If the file exists this will attempt to write over it.

type File

type File struct {
	// contains filtered or unexported fields
}

File implememnts fs.File.

func (*File) Close

func (f *File) Close() error

func (*File) OSFile

func (f *File) OSFile() *os.File

OSFile returns the underlying *os.File.

func (*File) Read

func (f *File) Read(b []byte) (n int, err error)

func (*File) ReadDir

func (f *File) ReadDir(n int) ([]fs.DirEntry, error)

func (*File) Seek

func (f *File) Seek(offset int64, whence int) (ret int64, err error)

func (*File) Stat

func (f *File) Stat() (fs.FileInfo, error)

func (*File) Write

func (f *File) Write(b []byte) (n int, err error)
