Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Search-and-replace with correct grammatical case - does it exist?
So you want to go from Spende to Spende+genitive to Beitrag+genitive to Beitrags. In addition to Spacy etc. you might look at Finite State Transducers, which I believe are bidirectional, i.e. for both analysis and generation. XFST and SFST and OpenFST are a few of the FST toolkits. See https://github.com/hfst/hfst for the Helsinki FST; there's a German transducer for it at https://sourceforge.net/projects/hfst/files/resources/morphological-transducers/hfst-german-installable.tar.gz/download. I don't think there is much of a learning curve, and there should be plenty of documentation.

Foldable Words
The regex syntax is a bit quirky due to backwards compatibility with lexicons written in XFST, see https://github.com/hfst/hfst/wiki/Regular-Expression-Operato...

A portable, modern regular expression language
Why don't languages have grok patterns in their standard libraries?
It seems to only exist in log parsing ecosystems but this really helps with getting rid of little bugs and wrong parsing of specific regex patterns.
Instead of doing "^\d+(\.\d+){3}$" for IP checking which is clearly wrong, you'd do "%{IPV4:ip}" which is so much better.

Even for PHP a third party library only has 15 stars.

Writing an effective GROK pattern
Also, some of the patterns can be referred from https://github.com/hpcugent/logstash-patterns/blob/master/files/grok-patterns I personally prefer the above link for constructing grok pattern.
