Simply source the ebuild, and SRC_URI and other variables will be set.
This wont work for ${P}, ${PN}, ${PV}, etc. etc. as they are not set in the 
ebuild themselves.

[gentoo-dev] Getting $SRC_URI in a bash program

[Viktor Lakics]

Hi devs,

I am learning bash, and since I run gentoo, I thought the best way
to learn is manipulate ebuilds:-)).

How can I extract the value of SRC_URI from a given ebuild in  a
bash program? Do I have to call emerge or ebuild somehow!? What I
would like is to get the exact URL or just the basename of the file
as a string to manipulate my distfiles.

Anyone has an idea?

Thanks in advance. -- Viktor

maybe this'll help as a way to get the .tar.* names from the ebuild filename.

[heim@tnt ~]$ ./test.sh /usr/portage/x11-wm/fluxbox/
fluxbox-0.1.10.tar.bz2
fluxbox-0.1.9-r5.tar.bz2
[heim@tnt ~]$
[heim@tnt ~]$ cat test.sh
#!/bin/bash

EBUILDS=`ls ${1}/*.ebuild`
SUFFIX='.tar.bz2'
for i in ${EBUILDS};
do
echo $i | sed -e 's:^/.*/::' -e 's:.ebuild$:${SUFFIX}:";
done


or, maybe you already have a variable set to the name of the ebuild:
------------------------
#!/bin/bash
EBUILDS='app-2.1.ebuild'
SUFFIX='.tar.bz2'

for i in ${EBUILDS};
do
echo $i | sed  -e "s:.ebuild$:${SUFFIX}:";
done
-------------------------
of course, you'll want to set SUFFIX to whatever it's set to in the ebuild
this'll get you the "gz" or "bz2" part.
[heim@tnt ~]$ cat /usr/portage/x11-wm/fluxbox/fluxbox-0.1.10.ebuild |grep 
SRC_URI|sed -e "s:.*/.*\.tar.::" -e 's:"$::'
gz
