This PR allows users of the library to configure the stemming function they want to use with the library, instead of having
Stemmer.stem/1
hardcoded. This is useful for me as I'd like to try this out with other languages.This changes the configuration API from
stem: true
tostem: &my_stem_function/1
. The old behavior can be obtained by usingstem: &Stemmer.stem/1
. Since users are now able to choose, I've also removed:stemmer
as a run-time dependency. I've updated the relevant docs that I could find.If you have any questions, don't hesitate to ask.
