I use the followiing two functions, the first is a copy paste from
unpack phase
alias nb="nix-build $(NIXPKGS_ALL) -A"
cdunpack () {
local curSrc="$1"
local b=$(basename "$1")
local dir="/tmp/${b}-unpacked"
[ -e "$dir" ] || {
mdc "$dir"
case "$curSrc" in
(*.tar) tar xvf $curSrc ;;
(*.tar.gz|*.tgz|*.tar.Z) gzip -d < $curSrc | tar xvf -
;;
(*.tar.bz2|*.tbz2) bzip2 -d < $curSrc | tar xvf - ;;
(*.zip) unzip $curSrc ;;
(*) if test -d "$curSrc"
then
stripHash $curSrc
cp -prvd $curSrc $strippedName
else
if test -z "$unpackCmd"
then
echo "source archive $curSrc
has unknown type"
return 1
fi
runHook unpackCmd
fi ;;
esac
}
cd $dir
}
cdsrc () {
cdunpack "$(nb ${1}.src --show-trace )"
}
Adjust to your liking.
