I wanted to use smartparens with blitzmax-mode, but the global ' completion was inserting two ' characters whenever I commented a line. Not the end of the world, but it was annoying and I wanted a solution.

smartparens can disable a global pair by setting :actions nil when using sp-local-pair. For blitzmax-mode, my config looks like this:

(use-package smartparens
  :diminish smartparens-mode
  :commands (smartparens-mode sp-local-pair)
  ((blitzmax-mode . smartparens-mode))
  (require 'smartparens-config)

  ;; Disable ' auto-pair in blitzmax-mode.
  (sp-local-pair 'blitzmax-mode "'" nil :actions nil))

Now smartparens inserts a single ' character when I comment a line, but still inserts matching ( and [ characters. Perfect!
