8 years agodoc-rst: add kernel-include directive
Markus Heiser [Fri, 8 Jul 2016 12:15:04 +0000 (14:15 +0200)] 
doc-rst: add kernel-include directive

The kernel-include directive is needed to include the auto generated rst
content from a build (pre-) process. E.g. the linux_tv Makefile
generates intermediate reST-files from header files. Since there is a O=
option:

  make O=dir [targets] Locate all output files in "dir"

We need to include intermediate reST files from arbitrary (O=/tmp/foo)
locations:

The 'kernel-include' reST-directive is a replacement for the 'include'
directive. The 'kernel-include' directive expand environment variables
in the path name and allows to include files from arbitrary locations.

.. hint::

  Including files from arbitrary locations (e.g. from '/etc') is a
  security risk for builders. This is why the 'include' directive from
  docutils *prohibit* pathnames pointing to locations *above* the
  filesystem tree where the reST document with the include directive is
  placed.

Substrings of the form $name or ${name} are replaced by the value of
environment variable name. Malformed variable names and references to
non-existing variables are left unchanged.

8 years agodoc-rst: customize RTD theme, table & full width

doc-rst: customize RTD theme, table & full width

The default table layout of the RTD theme does not fit for vast tables,
like the ones we have in the linux_tv project. This has been discussed
on the ML [1].

The RTD theme is a two column layout, with a navigation column on the
left and a content column on the right:

content column

 RTD theme's default is 800px as max width for the content, but we have
 tables with tons of columns, which need the full width of the
 view-port (BTW: *full width* is what DocBook's HTML is).

table

   - sequences of whitespace should collapse into a single whitespace.
   - make the overflow auto (scrollbar if needed)
   - align caption "left" ("center" is unsuitable on vast tables)

Parsing this file were causing lots of warnings with sphinx,

Fix that by prepending them with .. cpp:function::

While here, use the same way we document man-like pages,
at the V4L side of the book and add escapes to asterisks.
