Subject: [PATCH 04/10] scripts/sphinx-pre-install: always check if version is compatible with build
Call the script every time a make docs target is selected, on
a simplified check mode.
With this change, the script will set two vars:
$min_version - obtained from `needs_sphinx` var inside
conf.py (currently, '1.3')
$rec_version - obtained from sphinx/requirements.txt.
With those changes, a target like "make htmldocs" will do:
1) If no sphinx-build/sphinx-build3 is found, it will run
the script on normal mode as before, checking for all
system dependencies and providing install hints for the
needed programs and will abort the build;
2) If no sphinx-build/sphinx-build3 is found, but there is
a sphinx_${VER}/bin/activate file, and if
${VER} >= $min_version (string comparation), it will
run in full mode, and will recommend to activate the
virtualenv. If there are multiple virtualenvs, it
will string sort the versions, recommending the
highest version and will abort the build;
3) If Sphinx is detected but has a version lower than
$min_version, it will run in full mode - with will
recommend creating a virtual env using sphinx/requirements.txt,
and will abort the build.
4) If Sphinx is detected and version is lower than
$rec_version, it will run in full mode and will
recommend creating a virtual env using sphinx/requirements.txt.
In this case, it **won't** abort the build.
5) If Sphinx is detected and version is equal or righer than
$rec_version it will return just after detecting the
version ("quick mode"), not checking if are there any
missing dependencies.
Just like before, if one wants to install Sphinx from the
distro, it has to call the script manually and use `--no-virtualenv`
argument to get the hints for his OS:
You should run:
sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme
While here, add a small help for the three optional arguments
for the script.
