 Posted: Sun Nov 24, 2002 10:33 am Post subject: Script: Change USE flags according to ebuild to be merged |
 |
|
Well, I was searching for a script/program to change the USE flags of an ebuild - and that means only the USE flags it has specified in the .ebuild - interactively before merging it. Unfortunately, I didn't find one, so I had to do a little shell script by myself 
It might really suck, but here is it - I placed it as /usr/sbin/cemerge (custom emerge):
| Code: |
#!/bin/sh
# Change USE flags according to the ebuild to be merged
# and emerge it afterwards.
# --- BEGINNING OF USER SETTINGS ---
# Set your favourite editor
EDITOR=$EDITOR
# Set this to your PORTDIR_OVERLAY setting in make.conf
PO=/usr/portage.local
# Set temporary directory
TEMP=/tmp
# --- END OF USER SETTINGS ---
DIR=`emerge -s ^$1$ | grep \*.*$1 | head -n1 | sed -e 's/*\ //' | tr -d '[:space:]'`
if [ "$DIR" == "" ]
then
echo ""
echo "The specified ebuild does not exist."
echo ""
exit
fi
VERSION=`emerge -s ^$1$ | grep "Latest version available:" | head -n1 | sed -e 's/Latest\ version\ available\://' | tr -d '[:space:]'`
EBUILD=$PO/$DIR/$1-$VERSION.ebuild
if [ ! -f "$EBUILD" ]
then
EBUILD=/usr/portage/$DIR/$1-$VERSION.ebuild
if [ ! -f "$EBUILD" ]
then
echo ""
echo "FATAL ERROR: I can't find the ebuild!"
echo ""
exit
fi
fi
USEFLAGS=`cat $EBUILD | grep IUSE | head -n1 | sed -e 's/IUSE/USE/'`
if [ "$USEFLAGS" == "" ]
then
echo ""
echo "NOTICE: There are no USE flags to be set or available USE flags are not defined in the ebuild."
echo ""
emerge $1
exit
fi
if [ -f /tmp/$1-$VERSION.use_flags.temp ]
then
rm /tmp/$1-$VERSION.use_flags.temp
fi
echo $USEFLAGS >> /tmp/$1-$VERSION.use_flags.temp
$EDITOR /tmp/$1-$VERSION.use_flags.temp
FLAGS=`cat /tmp/$1-$VERSION.use_flags.temp | grep USE= | head -n1`
if [ -f /tmp/$1-$VERSION.use_flags.temp ]
then
rm /tmp/$1-$VERSION.use_flags.temp
fi
FLAGS=`echo "$FLAGS" | sed -e 's/USE=//'`
export USE=$FLAGS
emerge $1
# EOF. |
Maybe someone finds it useful..  |
