Handling of multiple Portfile versions

[Artur Szostak]

OK, I got confused because Rainer started off with "Yes this is supported...", sorry.
I conclude that what I am asking for is not supported.
Thanks.

OK, then given my specific example above, how do I install myport version 1.2 rather than version 3.4? Or conversely, how do I install version 3.4 rather than 1.2? It seems like you are telling me MacPorts will make a random selection and there is no way to control this. If that is the case then surely concurrent multiple versions of Portfiles from different repositories are not properly supported.

As quoted above: the first one found via sources.conf will be used. In this case it will be 3.4. You would need to swap the sources.conf entries to get 1.2.

OK, I misunderstood the selection mechanism of the port command. How about the following alternative, should that work?

port install myport and version:1\.2
port activate myport and version:1\.2

No. The first one found via sources.conf will be used; as you specified them that will *always* be 3.4. The other Portfile is effectively invisible; you *cannot* select it.
If, on the other hand, you had already installed via that Portfile (by swapping sources.conf entries as above), then you could manipulate *that* installation using the @version syntax (and it will use the Portfile stored in the registry from that install, not the one for the currently available version).

So if the command with the @version syntax is not following the dependencies when using the --follow-dependencies option, then I have a bug?

It follows the dependencies recorded for the specific version that you are removing. If those are incorrect then you have a Portfile bug for that version.
