ido-completing-read and substrings of choices

[Óscar Fuentes]

It seems that it is not possible to input a string that is a substring
of some candidate, even if require-match is nil:

(ido-completing-read "Choose: " '("abc" "xyz") nil nil)

How could the user input "ab" on the command above?

This should work :
ab C-j

Thanks Leo. Nico already answered this.

The documentation on ido.el is centered around selecting files and
buffers. However, ido-mode is so convenient that more and more people
are using ido-completing-read as a replacement for completing-read on
lots of contexts. IMHO ido-completing-read deserves move visibility on
the documentation at the top of ido.el or, better, explain the general
goal of ido-mode starting from ido-completing-read and present file and
buffer selection as specific applications.

Thanks again.

I agree. I actually change completing-read-function to a personally
modified ido-completing-read.

I am thinking of maintaining ido.el and give it a better documentation.
But writing texi doesn't thrill me. Let me think about it.

FWIW, the default completion code in Emacs has been slowly evolving to
get closer to IDO (e.g. in Emacs-24, C-x b does substring completion).
It will probably never be identical to IDO (because of some fundamental
UI incompatibilities), but feel free to request the addition of
particular IDO features via M-x report-emacs-bug.
