question about completing read

question about completing read

[Klaus Berndl]

The TABLE argument must be an alist where the car of each element must be a
string. Ok, but i have nowhere found anything about the cdr of the elements,
inall examples it is a sequence of numbers beginning from 1 but no explanation
why and no word about the cdr's in general! Am i blind?

First i supposed that the cdr of an element is returned when the car matches
but obviously this is not the case ;-)

Ok, what about these mysterious cdr's?

Thanks a lot,
Klaus

I believe they are ignored.  I guess it assumes an alist because
that's how it's often used.  I know in most/all of my usages of
completing-read, it's been with an alist of values.  You can then use
assoc to look up the cdr of the value.

i've used the alist with a font's readable string name, e.g.,
"terminal 9" in the car and its system descriptor in the cdr.
cheers.
