OK, and the reason why there is no need to update the actual code, other than the "do not allow" gate, is because "submodule--helper list" aka module_list already knows to list everything if no pathspec is given. Am I reading the code (not in the patch) correctly? > [1] http://news.gmane.org/gmane.comp.version-control.git/289535 The old discussion thread raises a good point. The refusal to accept no-pathspec form for a potentially destructive "deinit" may have been a safety measure, even though the suggested way to tell the command "Yes, I know I want to deinit everything" was not a good one (i.e. it resulted in an error if your project did not have any files tracked yet). So possible ways forward may be - to remove the safety altogether; or - keep the safety, but give a better suggestion to say "Yes, deinit everything". And this patch decides to take the former approach? I am wondering if this can be solved in a cleaner way to teach "deinit" take a new "--all" option instead, e.g. something like... diff --git a/git-submodule.sh b/git-submodule.sh index 82e95a9..4b84116 100755 --- a/git-submodule.sh +++ b/git-submodule.sh @@ -405,6 +405,7 @@ cmd_init() cmd_deinit() { # parse $args after "submodule ... deinit". + deinit_all= while test $# -ne 0 do case "$1" in @@ -414,6 +415,9 @@ cmd_deinit() -q|--quiet) GIT_QUIET=1 ;; + -a|--all) + deinit_all=t + ;; --) shift break @@ -428,9 +432,9 @@ cmd_deinit() shift done - if test $# = 0 + if test $# = 0 && test -z "$deinit_all" then - die "$(eval_gettext "Use '.' if you really want to deinitialize all submodules")" + die "$(eval_gettext "Use '--all' if you really want to deinitialize all submodules")" fi git submodule--helper list --prefix "$wt_prefix" "$@" | That would work even in the pathological "empty directory that has nothing to match even '.'" case without losing the safety, no? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
