Troubleshooting

For the times when parinfer-rust-mode needs your guidance.

Escape Hatch/ Evil Support

Is parinfer misbehaving in smart-mode? This could be due to a bug or because some commands(evil) are just plain weird. parinfer-rust-treat-command-as is an escape hatch for smart mode that allows you to tell parinfer-rust-mode what mode to run a specific command. parinfer-rust-treat-command-as is a list of pairs. The first item in the pair specifies the command and the second item in the pair specifies the mode the command should be run under. For example (yank . "paren"), tells parinfer-rust-mode to override smart mode and run under paren mode when it detects that yank caused a change in the buffer.

You can extend to parinfer-rust-treat-command-as using add-to-list as shown below:

(add-to-list 'parinfer-rust-treat-command-as '(your-command . "paren"))
;;or
(add-to-list 'parinfer-rust-treat-command-as '(your-command . "indent"))

Guile Support

If guile is your flavour of scheme you can override the scheme option in the parinfer-rust-major-mode-options plist with parinfer-rust-guile-options.

(setopt parinfer-rust-major-mode-options (plist-put parinfer-rust-major-mode-options 'scheme-mode 'parinfer-rust-guile-options))

Or overwrite the major-mode-options using a .dir-locals-el.

((scheme-mode . ((parinfer-rust-major-mode-options . (scheme-mode (:lisp-vline-symbols t
                                                                   :lisp-block-comments t
                                                                   :guile-block-comments t
                                                                   :scheme-sexp-comments t))))))

Vundo

If you use vundo you might occasionally get an error message like:

Error running timer ‘track-changes--call-signal’: (buffer-read-only #<buffer parinfer-rust-mode.el>)

This is caused by vundo locking the buffer as read-only while you are going through the undo-tree. The fix here would be to use vundo's hooks to turn parinfer-rust-mode off and on as necessary.

(use-package parinfer-rust-mode
 ;; ...
 :config
 (add-hook 'vundo-pre-enter-hook (lambda () (parinfer-rust-mode 0) nil t))
 (add-hook 'vundo-post-exit-hook (lambda () (parinfer-rust-mode 1) nil t)))
