# Changelog:
# 0.9999.3.0-1: 08/Mar/2012 by tlaronde@polynum.com
#              * Sketching how R.I.S.K. has to be used by the package
#                framework.
# 0.9995-1:     06/Mar/2012 by olivares14031@gmail.com
#              * Initial build.
#
# Run 'sh kerTeX.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'.
#
# -----------------------------------------------------------------------------
# [TL] Note that the official name is: kerTeX with a small leading 'k'
# to emphasize that TeX is the important part. There is no LaTeX is there
# is no TeX...
#
# [TL] A supplementary tip: if KERTEX_PKG_DIR is set in the environment
# at packaging time, the _kerTeX_ packages put in this dir will be
# added to the package. These are _kerTeX_ packages built from a running
# kerTeX. There are (if bin fmt, base etc.) binary dependent but hier
# independent. This is the crux.

# [TL] Actually, packaging kerTeX for whatever packaging framework is a
# simple 4 steps process:
#
# 1) Create a R.I.S.K. configuration file to take into account custom
# values given by the packager when calling this script, and
# configuring the kerTeX installed hierarchy conforming to the host
# filesystem hierarchy.
#
# 2) Let R.I.S.K. build everything (removing all that is
# automake/autoconf specific, since R.I.S.K. is a framework on is own).
#
# 3) Let R.I.S.K. install everything according to the filesystem
# hierarchy configured in a subdirectory.
#
# 4) Let the host packaging system gather this result. But since
# R.I.S.K. refuses to process if root, we will indeed install in a
# subdir and package while R.I.S.K. has switched to root for its own
# installation! So 4) is embedded in 3).
#
# As long as the version is concerned, this script could be always
# cutting edge: if there is saved in SRCDIR a tarball with the
# SlackBuild expected name, we use it. If not we download the latest
# version and set the version accordingly. This means that updating
# should be removing the saved tarball...
#
# For R.I.S.K. it refuses to process if being root, and switches only
# when needed. Period.
#
if test $(id -u) -eq 0; then
  echo "Don't run me as root _now_!" >&2
  echo "I will switch to root only when needed." >&2
  exit 1
fi

#========== STEP 1
#
# [TL] We respect the packaging framework protocol: the names, and will
# be configuring R.I.S.K. after these.

# Set initial variables:

PRGNAM=kertex
VERSION=0.9999.3.0	# to be set with the version of a _saved_ tarball
BUILD=${BUILD:-1}

# The TAG is a unique identifier for all your Slackware packages.
# Use your initials as the value for TAG for instance.
TAG=${TAG:-_ast}

# Where do we look for sources?
# [TL] The bundle can be already here (for packaging various flavors)
# renamed with the Slackbuild convention. If not, we will download
# from kergis.com, using the name of the bundle there.
#
SRCDIR=$(cd $(dirname $0); pwd)
SOURCE="$SRCDIR/${PRGNAM}-${VERSION}.tar.gz"
SRCURL=http://downloads.kergis.com/kertex_bundle.tar

# Place to build (TMP) package (PKG) and output (OUTPUT) the program:
# We will remove this TMP. So create an unlikely name (if someone
# defines TMP as '/'...), for concurrent builds, and don't fiddle with
# it once set! The risk suffix will be verified.
#
TMP=${TMP:-/tmp/}/_$$-$PRGNAM-risk
readonly TMP

# PKG will be installed "chrooted" here for packaging. Root created,
# root deleted.
#
PKG=$TMP/package-$PRGNAM

# The result. So not deleted... and not created either: must exist!
#
OUTPUT=${OUTPUT:-/tmp}

# [TL] R.I.S.K. has its own way (does cross-compilation). And needs
# explicit configuration. This script is a generic one. So we will
# only build package for this matrix arch, except that for Intel based
# we build for i486.
#
ARCH=$(uname -m)
case $ARCH in
  i?86) ARCH=i486; XCFLAGS="-march=i486 -mtune=i686 -O2";
	;;
  arm*) ARCH=arm;
	;;
esac

# 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}

_UMASK_=$(umask)

TMPDIR=$OBJDIRPREFIX
export OBJDIRPREFIX TMPDIR

# customized.

# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

This is a TeX kernel system providing what everything is based upon:
Donald E. Knuth's Digital Typography system; with some useful
additions.

This system includes, of course, METAFONT and TeX; but other utilities
as well.

All the programs (latest published version) are included here.

In addition, other programs linked to Tomas Rokicki's dvi to
PostScript driver (dvips(1)) are added. Oren Patashnik's BibTeX
(0.99d) is here too! John Hobby's MetaPost is included! The NTS team
e-TeX is here! And D.E. Knuth and Silvio Levy' CWEB are here too!

And since kerTeX aims to be a TeX system, a packaging framework has
been developed for it too!

                        You're done!
                Thank you for using KerTeX

You must now, as an _unprivileged_ user build the fonts and compile
the dump.

Just run:

	which_kertex

to see where stuff is installed. And then run:

	$KERTEX_BINDIR/adm/pkg_core install

Note that the man pages are put in kerTeX realm. So you will have to
add the paths (man.config(5)). This is so in order for you to test
different TeX distribution without one stepping on the others toes.

The path is displayed by which_kertex(1).

You should probably also edit dvips config to be found here:

$KERTEX_LIBDIR/dvips/dvips.cnf

to match the resolution and memory of your printer device, and to use
or not T1 version of Donald E. Knuth's Computer Modern Fonts.

==================================================================

NOTES:
in ~/.xinitrc or in ~/.bashrc, manually set the path, add the lines

Thanks to the author of KerTeX for a job well done!
