The Sphinx .. only:: directive is limited to handling only conditional
text and can't handling conditional use of directives. For example,
.. only:: test
.. automodule:: west.runners.core
:members:
is not handled. This PR monkey patches the handling of the existing
.. only:: directive done by Sphinx.
See https://github.com/pfalcon/sphinx_selective_exclude for details.

# This is a Sphinx documentation tool extension which makes .only::
|
|
# directives be eagerly processed early in the parsing stage. This
|
|
# makes sure that content in .only:: blocks gets actually excluded
|
|
# as a typical user expects, instead of bits of information in
|
|
# these blocks leaking to documentation in various ways (e.g.,
|
|
# indexes containing entries for functions which are actually in
|
|
# .only:: blocks and thus excluded from documentation, etc.)
|
|
# Note that with this extension, you may need to completely
|
|
# rebuild a doctree when switching builders (i.e. completely
|
|
# remove _build/doctree dir between generation of HTML vs PDF
|
|
# documentation).
|
|
#
|
|
# This extension works by monkey-patching Sphinx core, so potentially
|
|
# may not work with untested Sphinx versions. It tested to work with
|
|
# 1.2.2 and 1.4.2
