When I edit Haskell files, Emacs saves the file whenever I stop typing for more than a second. This is not auto-save mode, as it's overwriting the original file. Also, I disabled auto-save mode, and it still happens. It doesn't happen if I edit Java files or plain text files. How can I figure out what's happening, or better yet, stop it?

  • You should take a look at `haskell-mode.el`. Try to search `save` word there -- if You know elisp. Otherwise -- find the email of the author (in the top of `haskell-mode.el`) -- and drop him an email about it. – Adobe Mar 28 '13 at 05:19

A couple of things you can try:

  • Try M-x debug-on-entry save-buffer (or save-current-buffer etc.

  • M-: (add-hook 'before-save-hook '(lambda () (debug)))

The debugger should open whenever Emacs tries to save a buffer, so you can see what function (farther down the stack is asking for the buffer to be saved.

  • For unrelated reasons, I reinstalled my OS, and haskell-mode is working now. Thanks for the tip, though. – Adam Crume Sep 02 '13 at 02:28
  • I believe this is still an issue for me. While having a file watch on the whole directory, it seems to save the file after every few keystrokes. I've also tried setting the breakpoints, but none of these seem to get triggered. – Ashesh Apr 25 '20 at 13:07
