docs/conf.py: Respect env variable SPHINX_IMGMATH
On some distros with coarse-grained packaging policy, dvipng is installed along with latex. In such cases, math rendering will use imgmath by default. It is possible to override the choice by specifying the option string of "-D html_math_renderer='mathjax'" to sphinx-build (Sphinx >= 1.8). To provide developers an easier-to-use knob, add code for an env variable "SPHINX_IMGMATH" which overrides the automatic choice of math renderer for html docs. SPHINX_IMGMATH=yes : Load imgmath even if dvipng is not found SPHINX_IMGMATH=no : Don't load imgmath (fall back to mathjax) Signed-off-by: Akira Yokosawa <akiyks@gmail.com> Acked-by: Mauro Carvalho Chehab <mchehab@kernel.org> Link: https://lore.kernel.org/r/5a582b2b-d51c-a062-36b2-19479cf68fab@gmail.com Signed-off-by: Jonathan Corbet <corbet@lwn.net>
