What library is used in poetry for pretty printing errors?

• Improve UI #2230
• https://pypi.org/project/cleo/
• https://pypi.org/project/pastel/
• https://pypi.org/project/crashtest/ https://pypi.org/project/woops/

All from the author or poetry.

Looks like the error handling and formatting is done by whoops, but there are no docs or repo for it sdispater/clikit#23

To add to what @sinoroc said:

• woops has been replaced by crashtest (https://github.com/sdispater/crashtest, same library different name) which is responsible for manipulating and inspecting Python exceptions in an easier way. It also provides a "solution provider" system so that you can provide solutions for know exceptions.
• The actual error formatting is done in clikit (https://github.com/sdispater/clikit/blob/master/src/clikit/ui/components/exception_trace.py) – which willl soon be integrated back into cleo – by using crashtest internally.
• Poetry uses cleo at its heart for its CLI which, in turn, uses clikit.

Is there any chance to get pretty exception handler+printer available as a standalone library with stable API? I would sugar up a few open source projects that throw exceptions way too often to be friendly for new users.
