Subject: handling of completion table duplicates
Date: Sun, 03 Apr 2016 13:53:24 +0200 [thread overview]
Message-ID: <87h9fiewnf.fsf@acer.localhost.com> (raw)
Hi Everybody,
I recently noticed that ivy-mode (at its very core a completing-read
alternative, just like ido-completing-read is another one) does *not*
eliminate duplicates from the collection it is passed, eg, in form of a
plain list.
(completing-read "Prompt: " '("a" "b" "c" "a" "d"))
Both completing-read as well as ido-completing-read remove such
duplicates, but I could not find that behavior documented in the elisp
info manual or the docstrings.
Is removing duplicates from the collection *expected* from completion
functions, or is the caller of the function responsible for providing a
collection without duplicates?
If I did not just miss the documentation (in which case I apologize),
should this be documented, and where?
Ingo
