Improve runtime dependencies

[amotl]

Hi there,

at https://github.com/conda-forge/wetterdienst-feedstock/issues/53#issuecomment-1202058124, @kmuehlbauer said:

I'm having a hard time to understand which are required runtime dependencies of wetterdienst and which are optional. So the requirements.run section in meta.yaml would need some expert eyes on it.

With kind regards, Andreas.

Hi again,

from my perspective, that list does not look bad at all. At the first sight, I am not able to identify any wrong item in this list. Maybe @gutzbenj also wants to check and add additional thoughts here?

Cheers, Andreas.

@amotl that list doesn't look bad indeed. We could try to opt-out PyPDF2, as I think it is only used to parse meta information from DWD at this moment.

opt-out PyPDF2, as I think it is only used to parse meta information from DWD at this moment.

But what if that functionality would be needed? Should the user be advised to install the package manually instead? Why are you explicitly picking this module?

A few more general questions come to mind:

• Would it be favorable to reduce the list of runtime requirements further and make more packages optional?
• Is there a similar mechanism like pip's extras, to define sets of optional packages by name?

Hi again,

finally, https://github.com/earthobservations/wetterdienst/pull/788 will significantly reduce dependencies maybe previously declared to be needed at runtime, best reviewed per https://github.com/earthobservations/wetterdienst/commit/543ceb4f7.

Based on this change, and the next release, we may want to revisit the corresponding conda configuration.

With kind regards, Andreas.

I've just reviewed the list of dependencies again and believe they are good as they are. Feel free to reopen if you think differently.

[amotl]

Hm. Do we want to add those?

Packages found by source code inspection but not in the meta.yaml:

• plotly
• dash-bootstrap-components
• fastapi
• utm
• shapely
• pytz
• dash
• autovizwidget
• finesse

On this admonition, I think we can take those actions.

• No traces for cachetools, dataclass-wizard, deprecation, importlib_metadata, and requests-ftp. I guess those can be safely removed?
• beautifulsoup4 is only used within tests/ui/explorer/test_explorer.py, so I think it is also safe to remove from the list of runtime dependencies.

• requests-ftp

I've submitted #71, which just follows the suggestions by regro-cf-autotick-bot. Let me know what you think about it.

I think we can consider the improvement to be concluded. Thanks for your support, @xylar!
