Archived-At:
Create a file with a long filename like:
$ cat /tmp/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.el
(defun f () (g))
Then, byte-compile it in batch mode:
emacs -Q -batch -f batch-byte-compile /tmp/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa=
aaaaaaaaaaaaaaaaaaaaaaaaaaaa.el=20
In end of data:
/tmp/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.el:1:14:
Warning: the function =E2=80=98g=E2=80=99 is not known to be defined.
Note the line break after the column number.
For comparison, errors aren't broken up:
emacs -Q -batch -l bytecomp -eval '(setq byte-compile-error-on-warn t)' -f =
batch-byte-compile /tmp/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa=
aaaaaaaaa.el=20
In toplevel form:
/tmp/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.el:2:1: E=
rror: the function =E2=80=98g=E2=80=99 is not known to be defined.
This is inconsistent, and causes parsers (such as Emacs's compilation
mode) to incorrectly parse these messages. I think messages in batch
mode should never be broken up.
