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

This is exactly what I did, but it did not give me what I wanted, the complete URL or not even the file name. As you pointed out the problem is the variables which are not set in the ebuild themselves...Where are they set then? And how can I extract, get the file name?!

In other words : If I have /usr/portage/app-cat/app-2.1.ebuild then I want to get:

app-2.1.tar.bz2

or whatever the file is *ACTUALLY* called. I think this could be different from that you could deduct from simply the ebuild name...

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
