I'm using the ryo-modal package that enables you to define your own keys in modal editing. I'm trying to makemf move the cursor to the end of the word, insert a whitespace and then exit the modal mode. This works fine without the :then '(insert " ") part. However, I would really like to see my original idea working. Thanks in advance.

(ryo-modal-key "f" 'forward-word :then '(insert " ") :exit t)

Try this:

(ryo-modal-key "f" 'forward-word :then (list (lambda () (interactive) (insert " "))) :exit t)

  • @stefan Actually you don't need to make it interactive, and having a quoted list works as well. That being said, your edited answer works too (but isn't as compact). I'm the author of ryo-modal and the non-interactive lambda feature was added because I thought the code looked cluttered when writing interactive everywhere :) – Erik Sjöstrand Sep 27 '18 at 6:26
  • Then I suggest you change ryo-modal-key's docstring because it says "list of additional commands" and a non-interactive function is not a command (whereas a string is a command, as is a vector of commands). By the way I salso see you have (if (commandp f) (call-interactively f) ...) which should likely be replaced with (if (commandp f) (command-execute f) ...) since call-interactively doesn't know how to execute commands that are strings or vectors. – Stefan Sep 27 '18 at 12:39
  • Thanks for the suggestions @stefan. I'll look into command-execute (and how it is different to call-interactively) and I agree that the docstring should change. I actually didn't realize that (commandp "a") would be t, even though I knew strings could be used as commands. – Erik Sjöstrand Sep 27 '18 at 13:07
