Subject: Bug from profile path name?
Date: Thu, 3 Nov 2022 14:56:10 -0400

With an '@' character in the profile path I see the following error.

(the reason for using the full package <at> version in the profile path is
to preserve successfully built packages when garbage collecting during
testing of updates to dependent packages)

Greg

Well, the issue is ’@14’ is interpreted as TeXinfo.  Maybe the
replacement of ’texi->plain-text’ inside ’display-hint’ by
’texi->plain-text*’ and teach the latter for this “corner case“.

However, what is the “corner case”? :-) Any ’@thing’ for thing not a
keyword of TeXinfo?  Therefore, ’llvm <at> 14’ would work but not
’llvm <at> code’.  Why not? :-)


Cheers,
simon
