[Message part 1 (text/plain, inline)]
hide-ifdef-mode stores the list of current defines incorrectly when
function hide-ifdef-set-define-alist is used.
Steps to reproduce:
1. Start up with emacs -q.
2. Create a new buffer named test.c with the following contents:
#include <stdio.h>
int main(void)
{
#ifdef DEFINE1
printf("Define 1");
#endif
#ifdef DEFINE2
printf("Define 2");
#endif
#ifdef DEFINE 3
printf("Define 3");
#endif
return 0;
}
3. Hide some ifdefs as follows:
M-x c-mode
M-x hide-ifdef-mode
C-c @ d DEFINE2
C-c @ d DEFINE3
C-c @ h
- Result: DEFINE1 block is hidden, DEFINE2 and DEFINE3 blocks are shown.
4. Store and reload the defines as follows:
C-c @ D test-defines
C-c @ U test-defines
- Result: DEFINE1 and DEFINE2 blocks are hidden, DEFINE3 block is shown
- Expected: DEFINE1 block is hidden, DEFINE2 and DEFINE3 blocks are
shown as before.
5. Examine the stored alist:
M-x eval-expression hide-ifdef-define-alist
- Result: ((test-defines (DEFINE3 . 1) (DEFINE3 . 1)))
- Expected: ((test-defines (DEFINE3 . 1) (DEFINE2 . 1)))
Suggested fix:
I believe there is a bug in function hif-compress-define-list.
(defun hif-compress-define-list (env)
"Compress the define list ENV into a list of defined symbols only."
(let ((new-defs nil))
(dolist (def env new-defs)
-> (if (hif-lookup (car def)) (push (car env) new-defs)))))
Here, I think that (push (car env) new-defs) should have been (push (car
def) new-defs)
