Create new addon r.area.createweight

[CharlotteFlasse]

Hi developpers,

We are pleased to push a new add-on for GRASS GIS. It can be used to create a weighting layer for dasymetric mapping using a Random Forest model.

Looking forward for your feedback.

Hi all,
After an initial pull request, we get notified that Flake8 and Black quality check failed. So, we (@CharlotteFlasse and me @tgrippa) fix the different PEP8 issues in our add-on. We successfully run the Flake8 check and also Black on our own computer. Then, we commit and push the modification back to the forked repository that conducted to a new automatic check here in the ongoing pull request. However, the last check failed on both Black and Flake8 while it was not the case on our computer. We are not familiar with all these procedure for add-on submission so we are waiting for you to know what we are supposed to do now :)

Thanks

Most likely your version of black is too old. My Ubuntu 20.10 ships with black 19.x and it is too old. To format GRASS code, I have created a virtual environment with black 21.x from pip. This version is good enough to pass CI checks.

Hi @marisn and thanks for the tip. I installed black 21.x to be sure, but I realized that I misinterpret the check performed on Github. I thought the Black check do a reformatting while it is just a --check --diff without modification. I didn't pushed the modified version on commit 3084764. Now it is done on de43005.

I went through the manual page and made some grammar suggestions; hopefully someone else can have a look at the code

Thank you @veroandreo and @wenzeslaus for the review. I integrated all the requested changes. Let me know if an extra action is needed from my side.
