Subject: bug#4118: 23.1; eval-last-sexp-print-value is inconvenient
Date: Tue, 11 Aug 2009 06:55:30 -0400 [thread overview]
Message-ID: <19073.20002.692770.552510@winooski.ccs.neu.edu> (raw)
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
`eval-last-sexp' is often useful with a prefix argument inside a
buffer for all kinds of programmatic uses (for example, make a
keyboard macro that massages some text into an S-expression, then
use it to plant the result in the buffer). This uses
`eval-last-sexp-print-value', which will "helpfully" insert other
junk into the buffer (the hex and the octal representations of the
number). This is cute to have on the echo area, but annoying for
such use in macros. It would be better to disable this extra output
in the case of non-echo-area output.
I have a rather simple solution -- redefine the
`eval-last-sexp-print-value' function with an extra condition
(let ((str (and (eq standard-output t) ; <--- HERE
(eval-expression-print-format value))))
(if str (princ str)))
which works reasonably well.
