* docs: Create defs.rst.inc as a place to define substitutionsPeter Maydell2020-03-061-0/+6
| | | | | | | | | | | | | | | | | Rather than accumulating generally useful rST substitution definitions in individual rST files, create a defs.rst.inc where we can define these. To start with it has the |qemu_system| definition from qemu-block-drivers.rst. Add a comment noting a pitfall where putting literal markup in the definition of |qemu_system| makes it misrender manpage output; this means the point-of-use must handle the literal markup (which is almost always done by having it inside a parsed-literal block).

* configure: Check that sphinx-build is using Python 3Peter Maydell2020-02-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently configure's has_sphinx_build() check simply runs a dummy sphinx-build and either passes or fails. This means that "no sphinx-build at all" and "sphinx-build exists but is too old" are both reported the same way. Further, we want to assume that all the Python we write is running with at least Python 3.5; configure checks that for our scripts, but Sphinx extensions run with whatever Python version sphinx-build itself is using. Add a check to our conf.py which makes sphinx-build fail if it would be running our extensions with an old Python, and handle this in configure so we can report failure helpfully to the user. This will mean that configure --enable-docs will fail like this if the sphinx-build provided is not suitable: Warning: sphinx-build exists but it is either too old or uses too old a Python version ERROR: User requested feature docs configure was not able to find it. Install texinfo, Perl/perl-podlators and a Python 3 version of python-sphinx (As usual, the default is to simply not build the docs, as we would if sphinx-build wasn't present at all.)

* docs/sphinx: Add new hxtool Sphinx extensionPeter Maydell2020-02-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of our documentation includes sections which are created by assembling fragments of texinfo from a .hx source file into a .texi file, which is then included from qemu-doc.texi or qemu-img.texi. For Sphinx, rather than creating a file to include, the most natural way to handle this is to have a small custom Sphinx extension which reads the .hx file and process it. So instead of: * makefile produces foo.texi from foo.hx * qemu-doc.texi says '@include foo.texi' we have: * qemu-doc.rst says 'hxtool-doc:: foo.hx' * the Sphinx extension for hxtool has code that runs to handle that Sphinx directive which reads the .hx file and emits the appropriate documentation contents This is pretty much the same way the kerneldoc extension works right now. It also has the advantage that it should work for third-party services like readthedocs that expect to build the docs directly with sphinx rather than by invoking our makefiles. In this commit we implement the hxtool extension. Note that syntax errors in the rST fragments will be correctly reported to the user with the filename and line number within the hx file.

* sphinx: add qmp_lexerJohn Snow2019-07-101-2/+2
| | | | | | | | | | | | | | | | | | | | Sphinx, through Pygments, does not like annotated json examples very much. In some versions of Sphinx (1.7), it will render the non-json portions of code blocks in red, but in newer versions (2.0) it will throw an exception and not highlight the block at all. Though we can suppress this warning, it doesn't bring back highlighting on non-strict json blocks. We can alleviate this by creating a custom lexer for QMP examples that allows us to properly highlight these examples in a robust way, keeping our directionality and elision notations.

* docs: Provide separate conf.py for each manual we wantPeter Maydell2019-03-071-6/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default Sphinx wants to build a single manual at once. For QEMU, this doesn't suit us, because we want to have separate manuals for "Developer's Guide", "User Manual", and so on, and we don't want to ship the Developer's Guide to end-users. However, we don't want to completely duplicate conf.py for each manual, and we'd like to continue to support "build all docs in one run" for third-party sites like readthedocs.org. Make the top-level conf.py support two usage forms: (1) as a common config file which is included by the conf.py for each of QEMU's manuals: in this case sphinx-build is run multiple times, once per subdirectory. (2) as a top level conf file which will result in building all the manuals into a single document: in this case sphinx-build is run once, on the top-level docs directory. Provide per-manual conf.py files and top level pages for our first two manuals: * QEMU Developer's Guide (docs/devel) * QEMU System Emulation Management and Interoperability Guide (docs/interop) Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Aleksandar Markovic <amarkovic@wavecomp.com> Message-id: 20190305172139.32662-9-peter.maydell@linaro.org Message-id: 20190228145624.24885-9-peter.maydell@linaro.org
