I'm not sure what you are meaning here
I mean that when you install e.g. the port "docbook-xml-4.5" the
following message is displayed to the user:
######################################################################
# As MacPorts does not currently have a post-deactivate hook,
# you will need to ensure that you manually remove the catalog
# entry for this port when you uninstall it. To do so, run
# "xmlcatmgr remove nextCatalog /opt/local/share/xml/docbook/4.5/
catalog.xml".
######################################################################
If MacPorts had a post-deactivate hook, the port could do this task
itself and not need to bother the user with it. I know I sure as heck
am not going to remember what command some port asked me to run when
I uninstall it, since it's probably been months or years since I
installed it.
but if there is anything that a user NEEDS to do after uninstalling
a port maybe the port uninstall command could pause with the
message and wait for confirmation, bailing is the user clicks [n].
We can't do that today because port is not interactive (except in
interactive mode, but that still doesn't allow individual portfiles
to interact with the user). Anyway that's also not the solution I
would want; I would want proper deactivate and uninstall hooks.
This isn't a big deal but some people may do something silly like
"port uninstall installed echo p5-*" not knowing that it's going to
uninstall everything.
Ok, that was me :) Trying to figure out how to chain port commands.
There is no chain of port commands. You only get one action command,
but it can then act on any number of ports. In the above case, the
action you asked for is "uninstall", and you asked for it to act on
the pseudoport "installed" (which expands to the list of all
installed ports), and the nonexistent port "echo", and all ports
matching "p5-*". Here is the usage for the port command, from its
manpage:
port [-vdqfonRusbckixpt] [-D portdir] [-F cmdfile] [action]
[actionflags]
[[portname | pseudo-portname | port-url]]
[...@version] [+/-variant ...] ... [option=value ...]]
Part of the confusion arises because there are some keywords (for
example "installed" and "outdated") which are both actions and
pseudoports. As an action, "installed" shows you the versions and
variants of all ports you have installed, and "outdated" shows you
what ports are outdated along with their current and the newer
version that's now available. As pseudoports, "installed" expands to
the list of installed ports, and "outdated" to the list of outdated
ports. This lets you do things like "port upgrade outdated" (upgrade
all outdated ports) or "port info installed" (get info on every
installed port).
