# imgaug documentation build configuration file, created by
# sphinx-quickstart on Sat Aug 19 12:48:49 2017.
#
# This file is execfile()d with the current directory set to its
# containing dir.
#
# Note that not all possible configuration values are present in this
# autogenerated file.
#
# All configuration values have a default; values that are commented out
# serve to show the default.

# If extensions (or modules to document with autodoc) are in another directory,
# add these directories to sys.path here. If the directory is relative to the
# documentation root, use os.path.abspath to make it absolute, like shown here.
#
import os

import datetime


# --------------
# We add the parent directory here, which must contain imgaug/.
# This is necessary to automatically generate APIs via autodoc.
# We use here a variation of abspath() that accounts for symlinks to find the parent directory's path.
# This allows to symlink imgaug-doc in e.g. imgaug-project/ (containing then imgaug-doc/ and imgaug/),
# and still use e.g. `cd imgaug-project && cd imgaug-doc && make html` in imgaug-doc without errors.

# --------------

# --------------
# Currently we add imgaug/ source as a subfolder here, so that we can build the docs from the main directory
# and keep that main directory in a state where it only contains docs files.
# This allows us to link the imgaug-doc repository as doc/ from the main repo, but simultaneously also let RTD
# build the docs from imgaug-doc, including auto-generated API.
dir_path = os.path.abspath(os.path.dirname(__file__))
