#	This is a default set of rules for Makefiles for some
#	of my applications.  These rules should not be dependant
#	upon any specific application at all.
#
#	The original of this file is at:
#		http://mordred.ao.com/mkprogram/mkrules
#	Version = mkrules v0.09 regan@ao.com

all::

###
###	Definitions
###
###	These constants are used within this set of rules, as well
###	as by the main Makefile.
###
###	The user is expected to define or append to some of the
###	variables listed below.
###
###	These rules expect that the following rules are defined in the
###	main Makefile:
###		all		-- Main build
###	

#	$(TAREXCLUDE) is defined only by the user to set up additional
#	files to exclude from the archive.

#	$(HOMEURL) is defined in the main Makefile to indicate where this
#	program is distributed from.
HOMEURL = http://mordred.ao.com/mkprogram

#	$(MAJPROG) is defined in the main Makefile.  Here is a
#	silly hack to attempt to get by.  The user must have something like:
#		MAJPROG = bin/wordsearch.cgi
MAJPROG = $(shell find . -type f)

#	$(SRCDIRS) is the list of directories to be iterated over
#	for the various major "make" functions.  The user can add
#	items to this with:
#		SRCDIRS += newdir newdir2
SRCDIRS	= 

#	$(PKGNAME) is the package name.  This is derived from the current
#	directory, and is usually right.  If not, the user can override
#	this.
PKGNAME = $(shell pwd | sed "s:.*/::" | sed "s/-.*//")

#	$(VERSION) is the version ID out of the major program.  The
#	major program must be specified by the user like:
#		MAJPROG = bin/wordsearch.cgi
#	The Version string must exist in this file in a very stylized
#	fashion.
VERSION = $(shell grep "Version *= " $(MAJPROG) | head -1 | sed "s/.*v\([0-9.]*\).*/\1/")

#	$(BINDIR) is the directory that locally installed binaries live in.
#	The user can override this if appropriate.
BINDIR = /usr/local/bin

#
#	testvalues
#
#	Show the values used by a number of the definitions.
#	This is used during development to show that we are
#	working with the correct definition of the variables.
#
testvalues::
	@echo "Source directories: $(SRCDIRS)"
	@echo "Package name: $(PKGNAME)"
	@echo "Version ID: $(VERSION)"
	@echo "Major program: $(MAJPROG)"

#
#	version.wh is used for pages run through webc.
#
#version.wh:: $(MAJPROG)
version.wh::
	rm -f version.wh
	echo "#define _VERSION-$(PKGNAME)_ $(VERSION)" >version.wh
webc.src/version.wh::
	rm -f webc.src/version.wh
	echo "#define _VERSION-$(PKGNAME)_ $(VERSION)" >webc.src/version.wh

#
#	The tar file is created with the directory information in
#	it, with a filename containing the version ID.  As helpers,
#	there are symbolic links with constant names.
#
#	A number of files are excluded from the distribution.  The
#	user can exclude other files by defining a variable:
#		TAREXCLUDE = --exclude foo --exclude bar
#
tar:	dotar
dotar::
	rm -f $(PKGNAME).tar.gz
	ln -sf $(PKGNAME) ../$(PKGNAME)-$(VERSION)
	cd ..; tar --exclude RCS --exclude "*.tar.gz"		\
		--exclude "*.swp"				\
		--exclude Notes --exclude Data			\
		$(TAREXCLUDE)					\
		-cz -h -f $(PKGNAME).tar.gz $(PKGNAME)-$(VERSION)
	rm -f ../$(PKGNAME)-$(VERSION)
	mv -f ../$(PKGNAME).tar.gz $(PKGNAME)-$(VERSION).tar.gz
	chmod a+r,a-w $(PKGNAME)-*.tar.gz
	ln -sf $(PKGNAME)-$(VERSION).tar.gz $(PKGNAME).tar.gz

#
#	Make all of the static web pages.  This is done by going
#	to each directory and doing a "make".
#
all::
	here=`pwd`;				\
	for dir in $(SRCDIRS); do		\
	    cd $$dir; make; cd $$here;		\
	done

#
#	Remove everything that can be rebuilt.
#
clean::
	rm -f `find . -name "*.wc" -a -print | sed "s/\.wc/.html/"`
	here=`pwd`;				\
	for dir in $(SRCDIRS); do		\
	    cd $$dir; make clean; cd $$here;	\
	done

#
#	Install everything that needs installation.
#
install::
	here=`pwd`;				\
	for dir in $(SRCDIRS); do		\
	    cd $$dir; make install; cd $$here;	\
	done

#
#	The "update" rule gets a current copy of the program and
#	installs it.  As this does an install, this needs to be
#	done as root.  Watch out.
#
update::
	cd ..; GET $(HOMEURL)/$(PKGNAME).tar.gz >$(PKGNAME).tar.gz
	cd ..; tar xvfz $(PKGNAME).tar.gz
	cd `tar tfz $(PKGNAME).tar.gz | head -1`; make install
