Subject: Invisibility bug: `invisible' vs `display'
Date: Mon, 12 Feb 2007 20:00:11 +0100 [thread overview]
Message-ID: <87sldbtd50.fsf@wigwam.brockman.se> (raw)
[-- Attachment #1: Type: text/plain, Size: 11 bytes --]
Try this:
[-- Attachment #2: Type: application/x-emacs-lisp, Size: 988 bytes --]
[-- Attachment #3: Type: text/plain, Size: 1078 bytes --]
The test inserts the following text:
A: *
B: ?
C: *?
D: ?*
E: *?*
F: ?*?
G: ??
The `*' and `?' characters have `invisibile' properties
with a value of `t', so I expect to see none of them.
The `?' characters all have `display' properties with a
value of "!" (one of them has "$" instead, for clarity).
This, I believe, _should_ be irrelevant.
In other words, I expect to see the following:
A:
B:
C:
D:
E:
F:
G:
The actual result I get is this:
A:
B: ?
C:
D: ?
E:
F: ?
G: ?!
Those exclamation marks should not be there. What they all
have in common is that none of them are preceded by
invisible characters _without_ `display' properties.
That is, a character with both `invisible' and `display'
properties appears to display correctly (i.e., not at all)
if and only if it is preceded by an invisible character
without a `display' property.
I get the same (AFAICS) erroneous results if I put an image
or some space instead of a string on the `display' property.
