Scanning the Doxyfile's +# +# The doxygen builder scans all documentation source files which have +# the text 'doxyfile' in any case in their name. It understands +# @INCLUDE directives and will find all the dependencies of the +# documentation: +# +# * All the source files as selected by INPUT, INPUT_PATTERN, +# RECURSIVE and so on. +# +# * Any referenced tag-files +# +# * Documentation header and/or footer +# +# * The INPUT_FILTER program +# +# * Any included doxygen configuration files +# +# +# 2. Regenerating header and/or footer +# +# If needed, the doxy-header.html and/or doxy-footer.html file will be +# regenerated. The header and/or footer are generated from templates +# using a simple python based templating system called yaptu which is +# included in site_scons/lib/. +# +# +# 3. Calling doxygen +# +# The doxygen call itself is quite complex since there is some pre- +# and post-processing going on. We can separate this step into two +# steps +# +# * Building prerequisites (e.g. images) +# +# * The processing done by the Doxygen builder and +# site_scon/lib/doxygen.sh +# +# +# 3.1. Building prerequisites +# +# The prerequisites are images referenced by the documentation. These +# images are mostly generated using the Dia2Png builder. +# +# +# 3.2. The main doxygen build (Doxygen builder) +# +# The Doxygen builder will call the doxygen command to build the +# documentation. +# +# The doxygen command is configured as 'site_scon/lib/doxygen.sh' which +# does some additional processing in addition to calling doxygen +# proper +# +# * it sets environment variables depending on command line arguments. +# These variables are then used in the Doxyfile's +# +# * after doxygen is finished, 'installdox' is called to resolve +# tag file references. +# +# * the HTML documentation is post-processed using some sed, tidy, and +# an XSLT template +# +# * a generated tag file is post-processed using an XSLT template +# +# (see site_scon/lib/doxygen.sh for more information). The Doxygen +# configuration is set up such, that +# +# * doxygen calls 'site_scons/lib/filter.pl' on each source file. This +# filter will strip excess whitespace from the beginning of lines in +# '\code' and '
' blocks. Additionally it will expand all tabs,
+#   tab width is 8 spaces (there should be no tabs in the source but
+#   ...)
+#
+# * 'site_scons/lib/filter.pl' calls 'site_scons/lib/makeDiaImageMap.py'
+#   whenever finding a '\diaimage' command. This will create an image
+#   map (in an encoded form which will be fixed by html-munge.xsl
+#   later)
+#
+# * doxygen calls 'site_scons/lib/dot' to generate the 'dot' images.
+#
+# * 'site_scons/lib/dot' calls 'site_scons/lib/dot-munge.pl' on the
+#    .dot files. dot-munge.pl changes the font and font-size and adds
+#    line-breaks to long labels
+#
+# * 'site_scons/lib/dot' calls the real dot binary. If the resulting
+#   image is more than 800 pixels wide, dot is called again, this time
+#   using the oposite rank direction (top-bottom vs. left-right). The
+#   image with the smaller width is selected and returned.
+#
+#
+# 4. Fixing broken links
+#
+# After the documentation has been generated, additional calls first
+# to the 'linklint' and then to the 'fixlinks' target will try to fix
+# broken links generated by doxygen. First, 'linklint' will call the
+# linklint tool to check for broken links in the documentation.
+#
+# 'fixlinks' is then called which calls 'doclib/fixlinks.py' which
+# scans *all* html files, builds an index of all (unique) anchors and
+# then fixes the url part of all links with correct anchor but bad
+# file name.
