That sounds like a good plan. I like keeping the complexity here in the script. > diff --git a/Documentation/doc-diff b/Documentation/doc-diff > index c2906eac5e..f397fd229b 100755 > --- a/Documentation/doc-diff > +++ b/Documentation/doc-diff > @@ -2,20 +2,25 @@ > > OPTIONS_SPEC="\ > doc-diff [options] <from> <to> [-- <diff-options>] > +doc-diff (-c|--clean) > -- > j=n parallel argument to pass to make > f force rebuild; do not rely on cached results > +c,clean cleanup temporary working files > " This will cause parseopt to normalize "--clean" to "-c" (along with "--cle", etc). > parallel= > force= > +clean= > while test $# -gt 0 > do > case "$1" in > -j) > parallel=$2; shift ;; > + -c|--clean) > + clean=t ;; So this part can just test for "-c". AFAICT this is how "rev-parse --parseopt" has always worked, though the documentation is quite unclear. Other scripts seem to also use these redundant long options. I'm not opposed to including it as a defensive measure (or simply an annotation for the reader). > +cd_to_toplevel > +tmp=Documentation/tmp-doc-diff > + > +if test -n "$clean" > +then > + test $# -eq 0 || usage > + git worktree remove --force "$tmp/worktree" 2>/dev/null > + rm -rf "$tmp" > + exit 0 > +fi And this matches what I'd expect "--clean" to do. Makes sense. -Peff
