I've attached a first draft (barely tested, I'm more interested in what
you think of the ideas used - specifically OPTIONS_DESC).
I had to implement an OPTIONS_DESC knob that should be set per-port as
the 4th field is added. This is necessary because it's impossible to
tell the difference between 3 OPTIONS with a long description (12
fields) or 4 OPTIONS without a long description (12 fields). I've done
some basic testing but intend to clean it up and properly document - in
both bsd.port.mk and the Porter's Handbook - the additions, assuming the
approach I'm using is liked by the community.
The idea is that OPTIONS goes from:
NAME "Short Description" Status
to a 4 field format:
NAME "Short Description" Status "Long Description, probably
documenting the immediate dependencies and implications of the knob"
With the addition of the 4th field the OPTIONS_DESC variable must be
set, or everything related to OPTIONS will break. Eventually, as ports
switch to this format the OPTIONS_DESC knob can be removed and made the
default format of 4 fields.
Once a port uses the extended format the dialog screen supports using
'?' or F1 to view the long descriptions.
I've changed the following targets:
config
config-conditional
showconfig
rmconfig
If I've missed anything please let me know.
