Basically, I'm after a version of `read-string', but either allowing only some characters, or accepting only input matching some regex (possibly both). How do I do that? One way would be to use `read-from-minibuffer' with a suitable keymap, but that seems slightly low-level. If that is the way to go, is there a good way to set up a keymap so that nothing except some specified characters are self-inserting? IOW, is `suppress-keymap' the way to go or is there some other way? TIA, -- Marcin Borkowski http://mbork.pl
