Subject: bug#52566: 29.0.50; Wishlist: There should be a print-unreadable-function variable
Date: Fri, 17 Dec 2021 08:25:38 +0100 [thread overview]
Message-ID: <87zgoz1yml.fsf@gnus.org> (raw)
It should be called from print_vectorlike (and any other places that
print unreadable objects, but I'm not sure there are any other places),
and should probably have a signature like
OBJECT PRINTCHARFUN ESCAPEFLAG
If it returns nil, the object should be printed as normal.
This can then be used to implement a `readablep' function (that would
bind this to a function that signals an error, and then catch that
error), and also to possibly make an alternative version of prin1 that
returns whether it printed something unprintable.
