Indeed it can't, (member "erontuf" (string-perms "kudtce")) ; nil > Anyway, I would personally permute only consonants - if the > vowels are out of order, the brain can often fill in the > blanks pretty easily. Good point, OTOH that's the beauty with programming, you have to use your brain a lot so that you don't have to do that anymore - at all! Luckily we haven't reached the point yet where every problem can and is solved by a machine better than a human being. So there are still stuff for us to do! Like for example working on it ... > Also, it would be great to leverage ispell to exclude > non-words from the list of permutations - unfortunately, > I don't know how to do it Right, I asked some time ago why there isn't a lispy function to spell a single word, I got the answer there's no use case for that, I don't remember what the use case was back then but now we know there are at least two. Anyway I did this, it uses how ispell work when you use it interactively which, admittedly, doesn't look good but in terms of the interface it is usable with and from Lisp: (defun spell-word (word) (with-temp-buffer (save-excursion (insert word) ) (condition-case nil (not (ispell-word)) (error nil) ))) ;; (spell-word "length") ; t ;; (spell-word "lenght") ; nil > (calc-eval "fact(5)") => "120" > (calc-eval "fact(10)") => "3628800" Indeed, however that isn't lispy either ... Good that there is this list, suddenly I have stuff to do again :) -- underground experts united https://dataswamp.org/~incal
