To have 2 or more OPTIONS exclude each other 'dialog --menu' could be
used. To make this useful there would need to a way to specify
multiple 'dialog --menus'.
i.e:
OPTIONS_CHKLST=3D OPTIONS CHKLST2
OPTIONS_INPUT=3D USER GROUP
OPTIONS_MENU=3D MNU1 MNU2
OPTIONS=3D tag "description text1" \
tag2 "description text 2"
CHKLST2=3D tag "description text1" \
tag2 "description text 2"
OPTIONS_MNU1_TITLE=3D"Choose a Database backend"
OPTIONS_MNU1_OPTIONS=3D "MYSQL Enable Mysql Support" \
"PGSQL Enable Pgsql Support=
"
The code for the 'dialog --menu' would be similar to the current
'dialog --checklist', except it would only enable one option.
OPTIONS_USER_QUESTION=3D"What user do you want to run Apache as?"
OPTIONS_GROUP_QUESTION=3D"What group do you want to run Apache as?"
The code for multiple input boxes could be:
.if defined(OPTIONS_INPUT}
.for MNU in ${OPTIONS_INPUT}
=09TMPOPTIONSFILE=3D$$(mktemp -t portmnuoptions); \
=09trap "${RM} -f $${TMPOPTIONSFILE}; exit 1" 1 2 3 5 10 13 15; \
=09${SH} -c "${DIALOG} --inputbox $${OPTIONS_${MNU}_QUESTION} 1 70 2>
$${TMPOPTIONSFILE}"; \
=09status=3D$$?; \
=09if [ $${status} -ne 0 ] ; then \
=09=09${RM} -f $${TMPOPTIONSFILE}; \
=09=09${ECHO_MSG} "=3D=3D=3D> Options unchanged"; \
=09=09exit 0; \
=09fi; \
=09if [ ! -e ${TMPOPTIONSFILE} ]; then \
=09=09${ECHO_MSG} "=3D=3D=3D> No user-specified options to save for ${PKGNA=
ME}"; \
=09=09exit 0; \
=09fi; \
=09SELOPTIONS=3D$$(${CAT} $${TMPOPTIONSFILE}); \
=09${RM} -f $${TMPOPTIONSFILE}; \
=09WITH_${PORTNAME}_${MNU}=3D${SELOPTIONS}
.endfor
.endif
NOTE: The above code doesn't set a default value, or check if the
TMPOPTIONSFILE is just a space or empty.
I haven't figured out how to handle sub-OPTIONS.
