can't insert single quote (`'`) in expression minibuffer in strict mode

[Rogach]

Expected behavior

In strict mode M-: ' should result in single quote being typed in the expression minibuffer.

Actual behavior

Quote is doubled instead. And since this is strict mode, I can't delete the extra quote. Temporary workaround: use (quote).

Steps to reproduce the problem

Config that reproduces the problem:

(require 'smartparens-config)
(add-hook 'eval-expression-minibuffer-setup-hook #'smartparens-strict-mode)

Then type M-: (eval-expression) and then type single quote character (').

(defun aorst/minibuffer-enable-sp ()
  "Enable `smartparens-strict-mode' in the minibuffer, during `eval-expression'."
  (when (eq this-command 'eval-expression)
    (setq-local comment-start ";")
    (sp-local-pair 'minibuffer-pairs "'" nil :actions nil)
    (sp-local-pair 'minibuffer-pairs "`" nil :actions nil)
    (sp-update-local-pairs 'minibuffer-pairs)
    (smartparens-strict-mode 1)))

I hook this funtion to minibuffer-setup hook and it seems to work

[Rogach]

@andreyorst Thank you, that works!

I found that it is possible to get rid of "(when (eq this-command ..." by hooking eval-expression-minibuffer-setup-hook instead of minibuffer-setup-hook.

[andreyorst]

oh, great! Did not knew of that hook, thanks for the tip!

[andreyorst]

Perhaps this should be documented, and tiket can be resolved?

[Rogach]

Up to the project owner, I guess. I saw that he marked the issue as a bug, so maybe he plans to do something else (one could argue that smartparens-strict-mode should allow quotes in minbuffer as well as in usual .el buffers - because in both cases we have elisp as a dialect).
