git diff calendR-branch-point

from within your local clone of the calendRio Git repository or compare the main branch to the corresponding tag on GitLab to see the exact changes made since branching off from calendR (and therefore released under the less permissive licensing terms).

Motivation

When I wanted to create a calendar with custom annotation from within R, I came across the calendR R package by José Carlos Soage González of r-coder.com and Natalia Pérez Veiga that already did almost everything I needed.

After using it for a while, I came across a (very minor and niche) feature I 'needed' that was missing from the package: The ability to color the moon phase outlines by a gradient indicating the moon's progression. There had been other issues I had to work around (e.g. by adding additional text layers with different formatting using plain ggplot2 commands on top of the object returned by calendR) to get the exact results I was looking for, but this was the first one I was unable to solve without modifying the package source itself. Thankfully, the original authors had released calendR under a (permissive) free software license that allowed me to do so.

Following the free software philosophy, I decided to give back by sharing my work with others. Particularly, I opened a pull request on the project's GitHub page adding the new feature implemented by me to the upstream package in a backwards-compatible way. This pull request got merged at first by José Carlos Soage González but later got reverted again after Natalia Pérez Veigaexpressed concerns about the growing complexity of the function in question.

While I can relate to these concerns and consider them absolutely valid, I neither wanted to miss out on features rejected by the upstream authors, nor did I feel like building my own package from scratch when something this close to what I wanted was already out there. Thus, after some constructive exchange with José Carlos Soage González, I decided to maintain my own fork of the package.

Following an additional exchange with José Carlos Soage González, I further decided to license my changes (and thus the resulting versions of the package) under the GNU Affero General Public License to mitigate the risk of anyone capitalizing on my free of charge work while restricting the(ir) users' freedoms.

To allow for a better separation between the differently licensed projects, I decided to rename my fork. The name 'calendRio' not only hints at the relation to (and backwards compatibility with) calendR, but is also a nod to the upstream package's country of origin as a tribute to the original authors. And, coincidentally(?), the calendar I was creating that triggered me looking into this project in the first place (and thus ultimately responsible for the very existence of calendRio) happens to have been a Spanish calendar(io) as well. :-)
