That's a nice idea, how do you make it work with dialog?
No idea, this is still the design phase. :) Actually, a message I now
can't find suggested that dialog may be able to do it unchanged.
Followup:
dialog --item-help \
--checklist "Contrived options description example" 21 70 15 \
"ABC" "Enable ABC encapsulation of convoluted insoluble ..." "on" \
"variations when the complementary quantum reversal feature is undesirable" \
"DOCS" "Build and install documentation" "on" "" \
"XYZ" "Enabling XYZ sets compiler go-fast stripes, defeats ...," "off" \
"all safeguards, and begins a wholesale, awesome, breathtaking data mangling" \
"NLS" "Native Language Support via gettext utilities" "on" ""
Here is a patch to do it.
To use, apply patch. Pick a port and edit the option descriptions to be
longer than 49 characters. Then run 'make config'.
Notes:
This patch only does descriptions for the plain options right now.
Changes to the multi and single options would be the same thing. (Not
done because I'm hoping someone better at make(1) will have cleaner
methods.)
There's a cosmetic problem. The last description line at the bottom of
the screen remains after dialog exits. I have not found a way to clear
it in dialog.--- bsd.port.mk.orig 2012-06-11 08:53:43.000000000 -0600
