I don't feel positive about pretending to be "git submodule" when the
subcommand is internal-only. Such commands are only invoked as "git
submodule--helper foo" and we will probably never turn them into
external-facing "git submodule foo" [1]. Even if it is internal-only,
there is a debugging benefit to emitting a usage string with the
correct, non-user facing command name.
I admit it might be a bit confusing to have a mix of usage strings with
"submodule--helper" vs "submodule", but as long as we clearly label
which commands are user-facing and which aren't, it shouldn't be too
hard to maintain, e.g. this might just be a matter of adding comments to
the array of commands like:
static struct cmd_struct commands[] = {
/* User facing commands - pretend to be "git submodule" */
{"name", module_name},
{"add", module_add},
[...]
/* Internal-only commands */
{"clone", module_clone},
{"resolve-relative-url-test", resolve_relative_url_test},
[...]
};
Notably, even with this patch we still _kind of_ have 'pseudo usage
strings' that reference "git submodule--helper". These are just
internal-only commands that don't use the parse_options() API, e.g.
if (argc < 3)
die("submodule--helper push-check requires at least 2 arguments");
I think it's ok to leave them as-is, provided we also leave the other
internal-only commands as-is.
[1] For convenience, here is a list of all of the subcommands changed in
this patch and whether they are user-facing/internal-only:
User-facing Internal-only
- foreach - list
- init - name
- summary - clone
- sync - config
- absorbgitdirs - create-branch
- set-url
- set-branch
- add
