28.0.50; Suboptimal error formatting for missing struct slot |
|
Date: |
Mon, 09 Mar 2020 09:07:40 +0100 |
The following happens at least in Emacs 27, I haven't checked other
versions.
$ emacs -Q -batch -l backtrace -l cl-lib -l cl-macs -eval
'(cl-struct-slot-offset (quote backtrace-frame) (quote foobar))'
struct %S has no slot %S: backtrace-frame, foobar
This is because the error symbol `cl-struct-unknown-slot' has the
message "struct %S has no slot %S", but the error system doesn't use the
message as a format template. Probably the error message should just be
"struct has no slot" or so.
