hello, there's a way to redirect output of cider-eval-print-last-sexp to kill-new ?

@d.ian.b Currently no.

(cider-interactive-eval "(java.util.UUID/randomUUID)"
                        (nrepl-make-response-handler nil
                                                     (lambda (_buffer value)
                                                       (kill-new value)
                                                       (message "copied %s" value))
                                                     (lambda (_buffer out)
                                                       (kill-new out)
                                                       (message "copied %s" out))
                                                     (lambda (_ err)
                                                       (message "error evaluating: %s" err))
                                                     '()))

that copies both out and returned values. not sure if that's what you want. but read the docstring for nrepl-make-response-handler. or you could check out the source of cider-interactive-eval and pass a single handler in there that does what you want

I've stopped on nrepl-make-response-handler trying to understand

first steps on emacs-lisp 😅

thanks @dpsutton

(cider-interactive-eval "(java.util.UUID/randomUUID)"
                        (lambda (response)
                          (nrepl-dbind-response response (value)
                            (when value
                              (kill-new (format "%s" value))
                              (message "copied %s" value)))))

bit easier i suppose.

what is nrepl-dbind-response ?

wow, defmacro on elisp rs

I have to study more, thanks @dpsutton

your emacs should just go to definition if you hit m-. you can also use m-x apropos to read the docstring. but it should be a bit understandable: given a response from nrepl, bind the binding value to some notion of value in the repsonse. its essentially a dictionary that's defined somewhere in CIDER

yeah, I've put the entire dictionary on kill-new but it was not a stringp

newbie question, how can I see the type of some output on elisp? there is a (type output) ?

that would just be map destructuring in clojure. but emacs lisp doesn't have that functionality baked in. there are some macros that provide it but they are not super standard and have a bit of weird syntax

if you step through the function with the debugger it should be pretty visible. define the form above in a function and then instrument it and then call it

alternatively, check out nrepl-dict.el and its just a simple hashmap i believe

if you check out nrepl-make-response-handler you can see what it is using nrepl-dbind-response to capture

(nrepl-dbind-response response (content-type content-transfer-encoding body
                                                 value ns out err status id)
