Functions ¶
func CacheDir ¶
func CacheDir() string
Returns a directory suitable for storing cached data.
On Windows, this is the 'local' appdata directory. On *NIX, it is XDG_CACHE_DIR (or failing that, $HOME/.cache).
Returns "" if suitable path cannot be identified.
func CacheFilename ¶
Returns a filename under the directory returned by CacheDir.
func GetExitCode ¶
Given an error, determines if that error is an os/exec ExitError. If it is, and the platform is supported, returns the exitCode and nil error. Otherwise, passes through the error, and exitCode is undefined.
func IsNotEmpty ¶
Returns true if the error is ErrNotEmpty or the underlying POSIX error code error is ENOTEMPTY. Currently always returns false on Windows.
func OpenFileNoSymlinks ¶
Opens a file but does not follow symlinks.
func RemoveEmpty ¶
Delete a tree of empty directories. Returns non-nil error if an empty directory cannot be deleted. Does not return an error if there are non-empty directories. This function can be used to prune empty directories from a tree.
