Eval in buffer and pretty-print result in REPL as output

[stathissideris]

Is your feature request related to a problem? Please describe.

The workflow I’d like to try is typing long multi-line expressions in a .clj file and eval+pretty-print their results in the REPL where the results accumulate.

Describe the solution you'd like

I would like a function that is similar to cider-pprint-eval-last-sexp-to-repl but instead of inserting the result into the REPL as input, I would like it to be inserted as pretty-printed output instead. If the eval'ed expression is also added as if it was typed in the prompt of the REPL I think it would be even more usable (because then you'd see alternating input and output and it would be easier to follow what was executed and in what order) but I’d be happy with just the outputs.

Describe alternatives you've considered

I saw that something similar would be possible with getting the results in a popup buffer, but I prefer to see a “log” of results which accumulate.

Additional context

This mockup shows what the result of running this new command might look like. My cursor is on the left in dev.clj, and I've just ran the new command, which resulted in my s-exp being added as input in the REPL prompt and the result of the expression being pretty-printed just below.

I was planning to do this, but I realised that cider-insert-last-sexp-in-repl already accepts an argument that will evaluate the sexp after sending it to the repl (resulting in something similar to what is shown in the screenshot).

Hi @bbatsov and @stathissideris ,

As @paulojean has mentioned, C-u cider-insert-last-sexp-in-repl already does what is requested in this issue.

Do we still want to have a separate function for doing this?
If yes, please take a look at this: suvratapte@c177120#diff-3f8317548fccd07e43ee8e69be1b3171

Should I create a pull request with this?

[bbatsov]

I've added a small remark to your commit. In general it seems we need to have more of the special function behaviors added to menu bars and documented properly at docs.cider.mx.

[suvratapte]

Okay, I will do that. Thanks! :)

Hello again, cider-insert-last-sexp-in-repl does indeed do what I was asking about, but it leaves the REPL cursor in its original position. That means that after a few evaluations the screen gets completely filled and any new expressions and results move beyond the bottom of the frame. Is there any way to add advice to some function in order to get the buffer to scroll as the results of cider-insert-last-sexp-in-repl get added to it? I tried follow-mode but it didn't seem to do the trick.

Here's something that works for my current setup, you can modify it to suit your need; I can't say it's pretty!

(defun cider-recenter (&rest args)
  (interactive)
  (other-frame 1)
  (goto-char (point-max))
  (recenter -2)
  (other-frame -1))

(define-key cider-mode-map (kbd "s-e")
  #'(lambda () (interactive)
     (advice-add 'make-progress-reporter :override (lambda (&rest args)))
     (save-window-excursion (cider-insert-last-sexp-in-repl 1))
     (cider-recenter)
     (advice-remove 'make-progress-reporter (lambda (&rest args)))))

For anyone reading through -- the above commit with cider-insert-and-eval-last-sexp-in-repl was never merged. To get automatic output to REPL, you still need to make this customization in your own init.el.

Here's the user level code that worked for me to override the default cider-eval-last-sexp C-x C-e

(defun cider-insert-and-eval-last-sexp-in-repl (&rest args)
  "Insert the expression preceding point in the REPL buffer and eval."
  (interactive)
  (cider-insert-last-sexp-in-repl t))

(define-key cider-mode-map (kbd "C-x C-e") #'cider-insert-and-eval-last-sexp-in-repl)
