# Run 'sh minecraft.SlackBuild' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'. 
#
# -----------------------------------------------------------------------------

# Set initial variables:

PRGNAM=minecraft
SRCNAM=Minecraft
VERSION=${VERSION:-latest}
BUILD=${BUILD:-3}
ARCH=noarch
TAG=${TAG:-alien}

# Where do we look for sources?
SRCDIR=$(cd $(dirname $0); pwd)

# Place to build (TMP) package (PKG) and output (OUTPUT) the program:
TMP=${TMP:-/tmp/build}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:-/tmp}

SRCURL="https://s3.amazonaws.com/Minecraft.Download/launcher/${SRCNAM}.jar"

##
## --- with a little luck, you won't have to edit below this point --- ##

# Exit the script on errors:
set -e
trap 'echo "$0 FAILED at line ${LINENO}" | tee $OUTPUT/error-${PRGNAM}.log' ERR
# Catch unitialized variables:
set -u
P1=${1:-1}

# Save old umask and set to 0022:
_UMASK_=$(umask)
umask 0022

# Create working directories:
mkdir -p $OUTPUT          # place for the package to be saved
mkdir -p $TMP/tmp-$PRGNAM # location to build the source
mkdir -p $PKG             # place for the package to be built
rm -rf $PKG/*             # always erase old package's contents
rm -rf $TMP/tmp-$PRGNAM/* # remove the remnants of previous build
rm -rf $OUTPUT/{configure,make,install,error,makepkg}-$PRGNAM.log
                          # remove old log files
