Functions

func Walk

func Walk(roots []Root, add func(root Root, dir string), opts Options)

Walk concurrently walks Go source directories ($GOROOT, $GOPATH, etc) to find packages.

For each package found, add will be called with the absolute paths of the containing source directory and the package directory.

Unlike filepath.WalkDir, Walk follows symbolic links (while guarding against cycles).

func WalkSkip

func WalkSkip(roots []Root, add func(root Root, dir string), skip func(root Root, dir string) bool, opts Options)

WalkSkip concurrently walks Go source directories ($GOROOT, $GOPATH, etc) to find packages.

For each package found, add will be called with the absolute paths of the containing source directory and the package directory. For each directory that will be scanned, skip will be called with the absolute paths of the containing source directory and the directory. If skip returns false on a directory it will be processed.

Unlike filepath.WalkDir, WalkSkip follows symbolic links (while guarding against cycles).
