Hi list,

I want to write a function like `format', which gets a string with some
codes embedded (like "%a", "%b" etc., and "%%" to get a percentage
sign), and convert them to something (say, "%a" to the value of var-a,
"%b" to var-b etc.).  Is there any facility in Elisp to help with that
or do I have to do a search-and-replace manually?

Best,

See `format-spec' and `format-spec-make'.

Thanks a lot!  That was exactly what I needed.  (I mean, `format-spec';
I'm not sure why I would need `format-spec-make', assuming that I can
just use backquote and comma.)

Yes, I wondered the same thing. But I thought I'd mention it 
anyway. :-)
