Say we have two paths:
Is there any package/method that will help me determine if one is a subdirectory of another? I am looking at a cross-platform option.
You could try and use path.filepath.Rel():
func Rel(basepath, targpath string) (string, error)
Relreturns a relative path that is lexically equivalent to
targpathwhen joined to
basepathwith an intervening separator.
Join(basepath, Rel(basepath, targpath))is equivalent to
Rel("c:\foo\bar", "c:\foo\bar\baz") should be
baz, meaning a subpath completely included in
c:\foo\bar\baz, and without any ‘
The same would apply for unix paths.
That would make
c:\foo\bar\baz a subdirectory of
