# LaTeX macros for paper
# ----------------------
#
# To report the input settings and results, the final report's PDF
# (final target of this reproduction pipeline) uses macros generated
# from various steps of the pipeline. All these macros are defined in
# `tex/pipeline.tex'.
#
# `tex/pipeline.tex' is actually just a combination of separate files
# that keep the LaTeX macros related to each workhorse Makefile (in
# `reproduce/src/make/*.mk'). Those individual macros are
# pre-requisites to `tex/pipeline.tex'. The only workhorse Makefile
# that doesn't need to produce LaTeX macros is this Makefile
# (`reproduce/src/make/paper.mk').
#
# This file is thus the interface between the pipeline scripts and the
# final PDF: when we get to this point, all the processing has been
# completed.
#
# Note that if you don't want the final PDF and just want the
# processing and file outputs, you can remove the value of
# `pdf-build-final' in `reproduce/config/pipeline/pdf-build.mk'.
tex/pipeline.tex: $(foreach s, $(subst paper,,$(makesrc)), $(mtexdir)/$(s).tex)
# If no PDF is requested, or if LaTeX isn't available, don't
# continue to building the final PDF. Otherwise, merge all the TeX
# macros into one for building the PDF.
@if [ -f .local/bin/pdflatex ] && [ x"$(pdf-build-final)" != x ]; then
cat $(mtexdir)/*.tex > $@

echo "The processing has COMPLETED SUCCESSFULLY! But the final "

# The bibliography
# ----------------
#
# We need to run the `biber' program on the output of LaTeX to generate the
# necessary bibliography before making the final paper. So we'll first have
# one run of LaTeX (similar to the `paper.pdf' recipe), then `biber'.
#
# NOTE: `tex/pipeline.tex' is an order-only-prerequisite for
# `paper.bbl'. This is because we need to run LaTeX in both the `paper.bbl'
# recipe and the `paper.pdf' recipe. But if `tex/references.tex' hasn't
# been modified, we don't want to re-build the bibliography, only the final
# PDF.

# The final paper

# Run LaTeX in the `$(texbdir)' directory so all the intermediate and

# directory (top reproduction pipeline directory) to the `TEXINPUTS'
# environment variable.
