symex-repl does not work with Sly

[olnw]

Problem Description

Pressing r in the symex evil state should open the Sly REPL. Instead, I get a void function error. I am not too familiar with Sly, but I think this is due to sly-repl being deprecated in favour of sly-mrepl.

Relevant commits:

• https://github.com/joaotavora/sly/commit/420a9c95d2406fbf82cd4e9df1c405e32437e725 sly-repl.el is renamed to sly-repl-old.el

• https://github.com/joaotavora/sly/commit/aa38e429d84ac5bf15eec50501cb3e2a22aefde8 sly-repl-old.el is deleted

Steps to Replicate

1. Add to example.el:

   
   (require 'package)
   (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
   (package-initialize)

(setq inferior-lisp-program "sbcl")

(use-package sly :ensure t)

(use-package symex :ensure t :custom (symex-common-lisp-backend 'sly) :config (symex-initialize) :bind ("s-;" . symex-mode-interface))

2. Run `emacs -Q --load example.el`

3. Run `M-x toggle-debug-on-error RET`

4. Visit a Common Lisp source file

5. Invoke Sly with `M-x sly RET`

6. Activate symex with `s-;`, then press `r`

7. View the backtrace:

Debugger entered--Lisp error: (void-function sly-repl) sly-repl() symex-repl-common-lisp() symex-repl() funcall-interactively(symex-repl) command-execute(symex-repl)
