### Makefile for same-fringe implementations.

###--------------------------------------------------------------------------
### Notes about organization.
###
### Most projects have lots of stuff in just a few languages, so it makes
### sense to put the language configuration in one place.  This one's
### different.  Its entire purpose is to demonstrate lots of different
### approaches.
###
### So, at the top we declare the main targets; then each language has its
### configuration and build rules.

.SUFFIXES: .o
LANGS			 =
SOURCES			 =
TARGETS			 = $(patsubst %,%-fringe,$(LANGS))
CLEANFILES		 = $(TARGETS)

all::
clean::; rm -f $(CLEANFILES)

###--------------------------------------------------------------------------
### Silent rules stuff.

## Default verbosity setting.
V			 = 0

## Infrastructure.
v_echo			 = $(call v_echo_$V,$1)
v_echo_1		 =
v_echo_0		 = @printf "  %-6s %s\n" "$1" "$@";
V_HIDE			 = $(V_HIDE_$V)
V_HIDE_0		 = @

### Testing.

	  echo >&3 "*** $$lang";					\
	  printf "Test $$lang...";					\
	  time=`command time -o/dev/stdout -f "%U user; %S system; %E"	\
		./test ./$${lang}-fringe 2>&3`;				\
	  if [ $$? -eq 0 ]; then					\
	    win=$$(expr $$win + 1);					\
	    printf " ok ($$time)\n";					\
	  else								\
	    lose=$$(expr $$lose + 1);					\
	    printf " FAILED\n";						\
	  fi;								\
	done 3>test.log;						\
	if [ $$lose -eq 0 ]; then					\
	  echo "All $$win test(s) OK";					\
