Description (last modified by ryandesign (Ryan Carsten Schmidt))
As a laptop user I have intermittant network connectivity. It would be very useful if I could fetch all the sources needed for building a port and its uninstalled dependencies *before* building anything. One way to do this would be with a 'recursive' flag to 'port fetch'. Another (better, IMHO) option would be to allow 'fetch-first' as a permanent mode of operation. I would prefer to work this way all the time anyway.

I personally would rather have something that fetches binaries while dependencies are being compiled. This requires some heavy work on the dependency engine, though.

Paul, this is easy, too #--- port_install() {
port install $* & for i in
port deps $1 | tr -d "\r" | grep -v ^${1}
; doport fetch $i & fetch_deps $i;
done
} #---

Make -R work with 'port fetch'. Applied against version 1.320.

Updates the man page for the -R switch.
comment:4 Changed 18 years ago by francisga@…
I have attached a 20-line patch to port.tcl against MacPorts 1.320 that that makes the -R switch work with the fetch stage.
port -R fetch somepackage
will fetch everything needed to build and run somepackage, so that a later port install somepackage
will work even if offline.
I originally posted the patch to Ticket #11446, without realizing it was a dup of this ticket.

Don't use the -R switch, as it is already used for following dependents (not dependencies; some fun with english).
I propose to use -r, which could also be used on other actions. -r follow dependencies (e.g. on fetch) -R follow dependents (e.g. on upgrade)
Whereas -n is the opposite of -r.
This would be much more consistent than using -R for this.
comment:7 Changed 17 years ago by raimue (Rainer Müller)
To be consistent with other commands, we should use port fetch --follow-deps
for this.
comment:8 Changed 16 years ago by mroman@…
In general prefetching should be started in one thread and the another one should start building as soon as fetching of any source is completed. Just like it is implemented in portage for instance. It would be nice to see it in 1.8 release.

As of MacPorts 1.9, it's now easy to fetch all of a port foo's dependencies recursively:
sudo port fetch rdepof:foo

Has duplicate #31272.

The port-fetch-all.sh
script provided by the macportsscripts port also works for this purpose.
comment:13 Changed 11 years ago by lagrave+bugs+macosforge.org@…
Where do I find port-fetch-all.sh ? Google just pointed at this page.
comment:14 follow-up: 16 Changed 11 years ago by ryandesign (Ryan Carsten Schmidt)
Apparently here: https://github.com/derphilipp/macportsscripts
comment:15 Changed 11 years ago by ryandesign (Ryan Carsten Schmidt)
Or, as Eric said previously, by installing the macportsscripts port.

Replying to ryandesign@…:
Apparently here: https://github.com/derphilipp/macportsscripts
That was phw's original location for it; the macportsscripts port actually now pulls from my fork of it: https://github.com/cooljeanius/macportsscripts
adding this to your .bashrc will provide this feature right away (wether or not this feature will make it to port(1))
#--- fetch_deps() {
} #---
