# High-level directory definitions
# --------------------------------
#
# Basic directories that are used throughout the whole pipeline.
#
# Locks are used to make sure that an operation is done in series not in
# parallel (even if Make is run in parallel with the `-j' option). The most
# common case is downloads which are better done in series and not in
# parallel. Also, some programs may not be thread-safe, therefore it will
# be necessary to put a lock on them. This pipeline uses the `flock'
# program to achieve this.
texdir      = $(BDIR)/tex
srcdir      = reproduce/src
lockdir     = $(BDIR)/locks
indir       = $(BDIR)/inputs
texbdir     = $(texdir)/build
tikzdir     = $(texbdir)/tikz
mtexdir     = $(texdir)/macros
pconfdir    = reproduce/config/pipeline
# --------- Delete for no Gnuastro ---------
gconfdir    = reproduce/config/gnuastro
# ------------------------------------------




# System's environment
# --------------------
#
# Before defining the local sub-environment here, we'll need to save the
# system's environment for some scenarios (for example after `clean'ing the
# built programs).
sys-path := $(PATH)
sys-rm   := $(shell which rm)
curdir   := $(shell echo $$(pwd))


# High level environment
# ----------------------
#
# We want the full recipe to be executed in one call to the shell. Also we
# want Make to run the specific version of Bash that we have installed
# during `./configure' time.
#
# Regarding the directories, this pipeline builds its major dependencies
# itself and doesn't use the local system's default tools. With these
# environment variables, we are setting it to prefer the software we have
# build here.

SHELL           := .local/bin/bash
PATH            := $(curdir)/.local/bin
LD_LIBRARY_PATH := $(curdir)/.local/lib
LDFLAGS         := -L$(curdir)/.local/lib
CPPFLAGS        := -I$(curdir)/.local/include





# Make the high-level level directories
# -------------------------------------
#
# These are just the top-level directories for all the separate steps. The
# directories (or possible sub-directories) for individual steps will be
# defined and added within their own Makefiles.
#
# IMPORTANT NOTE for $(BDIR)'s dependency: it only depends on the existance
# (not the time-stamp) of `$(pconfdir)/LOCAL.mk'. So the user can make any
# changes within that file and if they don't affect the pipeline. For
# example a change of the top $(BDIR) name, while the contents are the same
# as before.
#
# The `.SUFFIXES' rule with no prerequisite is defined to eliminate all the
# default implicit rules. The default implicit rules are to do with
# programming (for example converting `.c' files to `.o' files). The
# problem they cause is when you want to debug the make command with `-d'
# option: they add too many extra checks that make it hard to find what you
# are looking for in this pipeline.
.SUFFIXES:
$(tikzdir): | $(texbdir); mkdir $@
$(texdir) $(lockdir): | $(BDIR); mkdir $@
$(mtexdir) $(texbdir): | $(texdir); mkdir $@





# High-level Makefile management
# ------------------------------
#
# About `.PHONY': these are targets that must be built even if a file with
# their name exists.
#
# Only `$(mtexdir)/initialize.tex' corresponds to a file. This is because
# we want to ensure that the file is always built in every run: it contains
# the pipeline version which may change between two separate runs, even
# when no file actually differs.
.PHONY: all clean distclean clean-mmap $(mtexdir)/initialize.tex
# --------- Delete for no Gnuastro ---------

        # programs. We'll use Bash's extended options builtin (`shopt') to
        # enable "extended glob" (for listing of files). It allows extended
        # features like ignoring the listing of a file with `!()' that we
        # are using afterwards.

	rm -rf $(BDIR)/!(dependencies)
