Bram: 'exe "silent <command>"' apparently does not give the same result
as ':silent exe <command>' (see example below). Bug or feature?

Can someone point me to a help topic that explains this (or give an

curbuf, and using echomsg instead of echo, but no combination of those
worked.
function! TestBuf()
let curbuf = bufnr("%")
exec "b" g:testbuf
let found = search('t.st')
exec "b" curbuf
echomsg 'Done with TestBuf (found = '.found.')'

Thanks much...Marvin
see ":help :silent"
HTH,
Tony.
I tried silent and silent!. I used it both places where I change
buffers with
exec "b" ...
e.g. exec "silent! b" ...
Did I miss something or put it in the wrong place?
Note that if you do the steps in my original message, then look at the
output of :messages, you will see that the output of the first exec "b"
... does not appear, and the output of the second appears _after_ the
output of echomsg, rather than before. Changing exec "b" to exec
"silent! b" has no effect.
I am using a self-compiled vim 7.0 that is slightly out-of-date (it only
has patches through 17). If you can't reproduce my problem with the
steps I outlined in my original message, I'll update my source,
recompile, and retry.

P.S. I am subscribed; no need to CC me.
No need, but it's easier: "Reply to All" does it. ("Reply to Sender"
would write only to you, not to the list; to write only to the list I
have to remove the Cc: line by hand.)

Conclusion: It's ":silent exe blahblah", not ":exe 'silent' blahblah".
Note that about half a screen below ":help :silent" there is an example
with ":silent exe normal".
Note: While doing those tests, I found that if the current buffer is
modified, the function will give an error at line 2. You may want to add
let save_hidden = &hidden
set hidden
at the start of the function, and
let &hidden = save_hidden
before returning. OTOH I don't quite understand why you must search an
auxiliary buffer rather than the current one being edited.
Best regards,
Tony.
