Building on my earlier explorations of the UDAR project, I’ve created a macOS Service-like method for in-situ marking of syllabic stress in arbitrary Russian text. The following video shows it in action:

The Keyboard Maestro is simple; we execute the following script, bracketed by Copy and Paste:

#!/Users/alan/.pyenv/shims/python3
import xerox
import udar
import re

rawText = xerox.paste()
doc1 = udar.Document(rawText, disambiguate=True)
searchText = doc1.stressed()
result = re.sub(r'( ,)', ",", searchText)
xerox.copy(result)

This presumes that udar and its prerequisites have already been installed, of course.

So why not build out this idea as an actual macOS text service? In theory, it should be possible. Maybe even ideal but for Python version management I use pyenv. Because some of the UDAR dependencies will not run under my current system Python version of 3.8.5, I use 3.7.4 under pyenv and it appears that the correct Python version run under whatever environment the service launches. Someone with deeper system knowledge could undoubtedly figure it out; but instead I accomplished the same effect via a Keyboard Maestro macro.
