Makes sense, but I needed to cheat and look at cmd_tag() to see how "force" is set to understand what is going on. I have to say "force" is not a good name for this field; is this use similar to what we typically use an additional _given field? > + } else if ((!opt->force_editor && !opt->message_given && is_null_oid(prev)) > + || (opt->force_editor && opt->use_editor)) { > + /* Editor must be opened */ If there is no --[no-]edit and there is no preexisting message, we need to use the editor. If the command line explicitly said --edit, we also would use the editor. OK. But it starts to make me wonder if you rather want to replace the single bit use_editor field with an enum with three possible values (enum { EDITOR_UNSPECIFIED, EDITOR_YES, EDITOR_NO } use_editor). > prepare_tag_template(buf, opt, prev, path, tag); > if (launch_editor(path, buf, NULL)) { > fprintf(stderr, > _("Please supply the message using either -m or -F option.\n")); > exit(1); > } > + } else if (!opt->message_given) { > + /* Tag already exists and user doesn't want to change it */ Are we certain at this point in if/else cascade that prev is a valid tag? How? > + strbuf_addstr(buf, get_tag_body(prev, NULL)); This NULL tells us something about what I mentioned in my review on 1/3. > diff --git a/t/t7004-tag.sh b/t/t7004-tag.sh > index 80eb13d94e..bf43d2c750 100755 > --- a/t/t7004-tag.sh > +++ b/t/t7004-tag.sh > @@ -1313,7 +1313,7 @@ test_expect_success GPG,RFC1991 \ > 'reediting a signed tag body omits signature' ' > echo "rfc1991" >gpghome/gpg.conf && > echo "RFC1991 signed tag" >expect && > - GIT_EDITOR=./fakeeditor git tag -f -s rfc1991-signed-tag $commit && > + GIT_EDITOR=./fakeeditor git tag -f --edit -s rfc1991-signed-tag $commit && > test_cmp expect actual > ' > > @@ -1356,7 +1356,7 @@ test_expect_success GPG,RFC1991 \ > test_expect_success GPG,RFC1991 \ > 'reediting a signed tag body omits signature' ' > echo "RFC1991 signed tag" >expect && > - GIT_EDITOR=./fakeeditor git tag -f -s rfc1991-signed-tag $commit && > + GIT_EDITOR=./fakeeditor git tag -f --edit -s rfc1991-signed-tag $commit && > test_cmp expect actual > ' Why do these two need explicit --edit option to invoke the editor? That smells like an unnecessary backward incompatible change. Thanks.
