Paredit and Curly braces in cider-repl-mode

[jsrodrigues]

I noticed that paredit mode for curly braces seems to be broken in the cider-repl. (add-hook 'paredit-mode-hook #'clojure-paredit-setup) in cider-repl.el does not fix the issue. I had to add the following lines in my emacs init file to fix this.

(add-hook 'cider-repl-mode-hook
          '(lambda ()
             (define-key cider-repl-mode-map "{" #'paredit-open-curly)
             (define-key cider-repl-mode-map "}" #'paredit-close-curly)))

Thanks for the report. I'd noticed this as well, and fixed it in the same way (you don't need to call define-key in the mode hook though, you can just call it at the top-level) - but forgot to file an issue :-).

The problem is that we call clojure-paredit-setup when enabling the mode, and this assumes that the keys should be set in the clojure-mode map - but clojure-mode is not active in REPL buffers (presumably it was at some point in the past).

I guess we can modify clojure-mode s.t. that function optionally takes a mode map - thoughts @bbatsov @Malabarba?

Sounds good.:+1:

Yeah, that sounds reasonable.
