# Custom release archive generation
#
# For each tagged revision, GitHub provides tar and zip archives that correspond
# to the output of git-archive
#
# These targets produce similar archives, featuring 3rd-party dependencies
# to ease deployment on shared hosting.

release_archive: release_tar release_zip

### download 3rd-party PHP libraries
composer_dependencies: clean
	composer update --no-dev
	find vendor/ -name ".git" -type d -exec rm -rf {} +

### generate a release tarball and include 3rd-party dependencies
release_tar: composer_dependencies
	git archive --prefix=$(ARCHIVE_PREFIX) -o $(ARCHIVE_VERSION).tar HEAD
	tar rvf $(ARCHIVE_VERSION).tar --transform "s|^vendor|$(ARCHIVE_PREFIX)vendor|" vendor/

# Targets for repository and documentation maintenance
##

### remove all unversioned files
clean:
	@git clean -df
	@rm -rf sandbox

### generate the AUTHORS file from Git commit information
authors:
	@cp .github/mailmap .mailmap
	@git shortlog -sne > AUTHORS
	@rm .mailmap

### generate Doxygen documentation
doxygen: clean
	@rm -rf doxygen
	@( cat Doxyfile ; echo "PROJECT_NUMBER=`git describe`" ) | doxygen -

### update the local copy of the documentation
doc: clean
	@rm -rf doc
	@git clone https://github.com/shaarli/Shaarli.wiki.git doc
	@rm -rf doc/.git

### Generate a custom sidebar
#
# Sidebar content:
#  - convert GitHub-flavoured relative links to standard Markdown
#  - trim HTML, only keep the list (<ul>[...]</ul>) part
htmlsidebar:
	@echo '<div id="local-sidebar">' > doc/sidebar.html
	@awk 'BEGIN { FS = "[\\[\\]]{2}" }'\
	'm = /\[/ { t=$$2; gsub(/ /, "-", $$2); print $$1"["t"]("$$2".html)"$$3 }'\
	'!m { print $$0 }' doc/_Sidebar.md > doc/tmp.md
	@pandoc -f markdown -t html5 -s doc/tmp.md | awk '/(ul>|li>)/' >> doc/sidebar.html
	@echo '</div>' >> doc/sidebar.html
	@rm doc/tmp.md

### Convert local markdown documentation to HTML
#
# For all pages:
#  - infer title from the file name
#  - convert GitHub-flavoured relative links to standard Markdown
#  - insert the sidebar menu
htmlpages:
	@for file in `find doc/ -maxdepth 1 -name "*.md"`; do \
		base=`basename $$file .md`; \
		sed -i "1i #$${base//-/ }" $$file; \
		awk 'BEGIN { FS = "[\\[\\]]{2}" }'\
	'm = /\[/ { t=$$2; gsub(/ /, "-", $$2); print $$1"["t"]("$$2".html)"$$3 }'\
	'!m { print $$0 }' $$file > doc/tmp.md; \
		mv doc/tmp.md $$file; \
		pandoc -f markdown_github -t html5 -s \
			-c "github-markdown.css" \
			-T Shaarli -M pagetitle:"$${base//-/ }" -B doc/sidebar.html \
			-o doc/$$base.html $$file; \
	done;
