From 606b9ac81a63ab3adb7e61206b9ae34ee186a89d Mon Sep 17 00:00:00 2001 From: Markus Heiser Date: Sat, 13 Aug 2016 16:12:42 +0200 Subject: [PATCH] doc-rst: generic way to build only sphinx sub-folders Add a generic way to build only a reST sub-folder with or without a individual *build-theme*. * control *sub-folders* by environment SPHINXDIRS * control *build-theme* by environment SPHINX_CONF Folders with a conf.py file, matching $(srctree)/Documentation/*/conf.py can be build and distributed *stand-alone*. E.g. to compile only the html of 'media' and 'gpu' folder use:: make SPHINXDIRS="media gpu" htmldocs To use an additional sphinx-build configuration (*build-theme*) set the name of the configuration file to SPHINX_CONF. E.g. to compile only the html of 'media' with the *nit-picking* build use:: make SPHINXDIRS=media SPHINX_CONF=conf_nitpick.py htmldocs With this, the Documentation/conf.py is read first and updated with the configuration values from the Documentation/media/conf_nitpick.py.
