Subject: bug#21237: 25.0.50; defconst vs dump
Date: Tue, 11 Aug 2015 15:07:21 -0500 [thread overview]
Message-ID: <86oaidy4g6.fsf@stephe-leake.org> (raw)
Given these two definitions:
(defconst format-1
(let ((str "(%s %s)"))
(put-text-property 1 3 'face 'font-lock-keyword-face str)
(put-text-property 4 6 'face 'font-lock-function-name-face str)
str))
(defvar format-2
(let ((str "(%s %s %s)"))
(put-text-property 1 3 'face 'font-lock-keyword-face str)
(put-text-property 4 6 'face 'font-lock-function-name-face str)
str))
If I byte-compile a file containing these, and later load that
byte-compiled file, the text properties are present on both format-1 and
format-2.
However, if the file is dumped for preloading into emacs, then the text
properties are not present on format-1; the defconst apparently causes
them to disappear.
If this is desired/intended behavior, it should be documented in the
defconst doc string, and there should be a warning during the dump
process.
