I have a plugin that needs to track the line number of the cursor in
order to display some information in the status line. The
CursorHold event works fine for this except when a buffer is first
opened, as when opening a quickfix error file with -q. I thought
that I could use the BufWinEnter event to grab the initial line
number in this case, but it appears to be triggered before the
quickfix procedure moves the cursor.
This behavior can be demonstrated as follows. The source file
main.c contains an error at line 5.
#include <stdio.h>
main(int argc, char *argv[])
{
exit(0);
}
When an error file is generated and opened with Vim's -q option, the
line number at the time of the BufWinEnter event is 1. I would
think it would be 5, the line number that the cursor is on when the
buffer is displayed.
$ make main > make.out 2>&1
$ vim -N -u NONE -i NONE --cmd 'au BufWinEnter * let a=line(".")' -c 'let
b=line(".")' -q make.out
:echo a b
1 5
Is this a bug? ":help BufWinEnter" says it is triggered "After a
buffer is displayed in a window." It appears to be triggered before
the buffer is displayed.
Regards,
Gary
