amber/amber/st/Makefile

#
# This Makefile takes .st files in the amber/st directory and produces compiled
# javascript files from them, for both debug and deployment.
#
# Where we find the current runnable code and where we put our js files on install
JS	:= ../js/

# The compiler script
AMBERC	:= ../bin/amberc

# Generic flags to AMBERC
FLAGS   := -d

# All corresponding js filenames for every st file available
# In other words, if we have Kernel.st and Compiler.st, then OBJECTS will be "Kernel.js Compiler.js"
OBJECTS := $(patsubst %.st,%.js,$(wildcard *.st))

# Default make target since it is the first target in this Makefile
all: $(OBJECTS)

# Step by step
#
# First we copy the core javascript files from current working files
# into this directory. These files are hand written or generated using
# other tools (parser.js). $@ is the target name.
boot.js init.js parser.js:
	cp ../js/$@ .

# Then we compile Kernel-*.st files depending on having boot.js, init.js and parser.js
# $< means the first dependency - in other words Kernel-*.st

# ...and Compiler, but using the new Kernel from above.
# We only need to depend on Kernel js files since it in turn depends on boot.js etc

# ...now that we have a new Kernel and Compiler we use them
# to compile the rest of st files presuming that they only depend on Kernel, like
# for example Canvas.js and Benchfib.js.

	$(AMBERC) $(FLAGS) $<

# But for some libraries there are more dependencies to care for. Then
# we need to use -l so that the compiler first loads that library
# before compiling the .st file. Otherwise bindings will fail.
#
# NOTE: With the new dependency model in class Package etc this will change!
