@orome Do you have any thoughts on this?
This issue occurs due to optparse-applicative 0.18 switching to prettyprinter. This also means that Options.Applicative.Help.Pretty does not export string anymore.
The changelog for optparse-applicative contains the following remarks:
Move to 'prettyprinter` library for pretty printing.
This is a potentially breaking change when one uses the '*Doc' family of functions (like headerDoc) from Options.Applicative. However, as versions of 'ansi-wl-pprint > 1.0' export a compatible Doc type, this can be mitigated by using a recent version.
One can also either import directly from Options.Applicative.Help or from the Prettyprinter module of 'prettyprinter'.
The file in question (cli/enigma.hs) seems to use string in combination with footerDoc, and that occurs twice:
footerDoc (Just $ string $ ...other text...)
Once this issue is resolved, please also release a new version on Hackage, as this issue is blocking the upgrade to optparse-applicative 0.18.1 in the Arch repos.
Thanks you for your time!
