Python Sphinx exclude patterns
exclude_patterns
can be used to exclude source files (reStructuredText files) from processing by sphinx-build.
exclude_patterns
has no effect when using sphinx-apidoc to generate reStructuredText files from Python modules (but you can tell sphinx-apidoc that certain pathnames should be excluded from the generation).
Docs for exclude_patterns indicate that 'workflow/definitions'
should ignore that directory, assuming that the source files all end with .rst
.
You can configure the source file suffices as a list:
source_suffix = ['.rst', '.txt']
