:update in autocmd doesn't trigger Write events

[Idan Kamara]

Hi,

Calling update in an autocmd CursorMoved/I doesn't seem to trigger BufWritePost (or FileWritePost or FileAppendPost).

$ gvim -u NONE /tmp/foo.c

:au CursorMoved *.c silent up

:au CursorMovedI *.c silent up

:au BufWritePost *.c echo 'saved'

When I make changes to the file, it does call update but I never see 'saved' in the status bar.

Writing the file explicitly using :w does trigger it.

Basically what I'm trying to do is call update and do something if the buffer was actually saved.

Thanks.

Nice, thanks for the pointer.

I'm curious why ':au CursorMoved *.c nested update' triggers BufWritePost, but 'silent update' doesn't.
Couldn't find anything in the help regarding possible side-effects of :silent.
