[gdal-dev] Motion: RFC 78: gdal-utils package

[Daniel Evans]

There’s also the option of using the “extra dependencies” functionality for Python packages, which is often used for including, well, extra features!

https://setuptools.readthedocs.io/en/latest/userguide/dependency_management.html#optional-dependencies

Again, it’s not entirely the intended use case – the normal use is for real dependencies that enable/improve functionality of the base package – but perhaps a bit more palatable.

(I do wonder if worrying about how to tie it to the GDAL PyPI package is really a major point for many users, given the difficulty of installing and compiling it compared to the pre-compiled packages from other sources. Will those changes affect those distributions, too?)

Hi Alan,

pip install gdal-utils
Will install also gdal as it is its dependency.

In case we will take the utils out of the gdal sdist - Even tough your suggestion to add gdal-utils as a dependency to gdal would make `pip install gdal` to also install both, it makes less sense to me as gdal does not actually depend on gdal-utils and it might complicate things in other ways. In that case, IMHO telling people who want to install the utils to pip install gdal-utils makes more sense...

You mentioned that gdal_utils is now on pypi. Are you able to set it as a dependency in the setup.py so it is installed when the main osgeo/gdal python package is installed?

Best,
Alan
