33 | # The function takes at most 2 arguments. The first argument is the |
34 | # URL that navigates to the submodule origin repo. When relative, this URL | |
35 | # is relative to the superproject origin URL repo. The second up_path | |
36 | # argument, if specified, is the relative path that navigates | |
37 | # from the submodule working tree to the superproject working tree. | |
38 | # | |
39 | # The output of the function is the origin URL of the submodule. | |
40 | # | |
41 | # The output will either be an absolute URL or filesystem path (if the | |
42 | # superproject origin URL is an absolute URL or filesystem path, | |
43 | # respectively) or a relative file system path (if the superproject | |
44 | # origin URL is a relative file system path). | |
45 | # | |
46 | # When the output is a relative file system path, the path is either | |
47 | # relative to the submodule working tree, if up_path is specified, or to | |
48 | # the superproject working tree otherwise. | |
