Should I expect a +quartz variant to propagate to dependencies, and overrule

Variants specified on the command line when installing a port propagate to any
dependencies that have not yet been installed. They do not propagate to any
dependencies that have already been installed.
That is good to know, thanks.
I looked at the Guide to see if this behaviour was described. In my
opinion it is not described adequately. I've opened a ticket against the
Guide, " Guide 3.2.1: Say that variant specification on port install
does not overrule existing ports" <https://trac.macports.org/ticket/65299>.
You can add a variant to an already-installed port by using "sudo port upgrade
--enforce-dependencies someport +somevariant".
Clever! I see that this is documented in
<https://guide.macports.org/#using.port.upgrade>. I had not noticed
that. I guess I have not read the Guide diligently.
…Thus I succeeded in fumbling my way through installing gimp +quartz despite
dependencies already present with the wrong variants, but it was a bit messy
and confusing. Should I expect MacPorts to do a better job with this situation?
If so, maybe I should file a ticket against some of these ports, to see if
portfile changes would avoid the problems.
This undesirable experience is why we recommend users choose whether to use
+x11 or +quartz before installing any ports, or uninstall all ports and
reinstall them if changing one's mind after having installed ports.
Interesting! Where is this advice documented? I certainly did not know
it before. (But them, I guess I have not read the Guide diligently.) The
place where these instructions would have done me good is in the
Migration instructions: <https://trac.macports.org/wiki/Migration>.
I just looked. I have 27 ports with +x11 variants specified. 4 of those
ports have +quartz+x11: cairo, cairomm, pango, pangomm. For all 4 of
them, +x11 and +quartz appear to be default variants, so I suppose they
can coexist. But that leaves me with 23 ports with +x11 to deal with. At
least some of them (e.g. ffmpeg) have no +quartz variant. Can such ports
coexist as +x11 variants with the rest of a collection of +quartz
variant ports?
I see my port gtk3 is installed as +x11 but not as +quartz. I suspect
that is not what I want. Thank you for the heads-up.
Thank you again for the explanation. Best regards,
