Overview

Package fspath implements the Walk function from filepath, but operating over a http.FileSystem. The implementation is almost entirely taken from filepath as of go1.12

Index

• Variables
• func Walk(fs http.FileSystem, root string, walkFn WalkFunc) error
• type WalkFunc

Variables

var SkipDir = errors.New("skip this directory")

SkipDir is used as a return value from WalkFuncs to indicate that the directory named in the call is to be skipped. It is not returned as an error by any function.

Functions

func Walk

func Walk(fs http.FileSystem, root string, walkFn WalkFunc) error

Walk walks the file tree rooted at root, calling walkFn for each file or directory in the tree, including root. All errors that arise visiting files and directories are filtered by walkFn. The files are walked in lexical order.

Types

type WalkFunc

type WalkFunc func(path string, info os.FileInfo, err error) error

WalkFunc is the type of the function called for each file or directory visited by Walk. The path argument contains the argument to Walk as a prefix; that is, if Walk is called with "dir", which is a directory containing the file "a", the walk function will be called with argument "dir/a". The info argument is the os.FileInfo for the named path.

If there was a problem walking to the file or directory named by path, the incoming error will describe the problem and the function can decide how to handle that error (and Walk will not descend into that directory). In the case of an error, the info argument will be nil. If an error is returned, processing stops. The sole exception is when the function returns the special value SkipDir. If the function returns SkipDir when invoked on a directory, Walk skips the directory's contents entirely. If the function returns SkipDir when invoked on a non-directory file, Walk skips the remaining files in the containing directory.
