I am learning emacs at the moment and tried to write an easy vhdl program for testing. I can see that the vhdl-mode might be an interesting feature, but I would like to know how I can turn it off for the moment and how I can reactivate it later on.

Use the command M-x fundamental-mode, that is:

  • Press (and hold) the meta key (which is usually the Alt key)
  • Press x

This will take the cursor into the echo area at the bottom of the screen/frame. Type fundamental-mode and press return.

To disable VHDL mode permanently, you will have to change the file-extension mapping used by emacs to associate a file's extension with a particular major mode. You can do this by writing a custom .emacs configuration file. Look for auto-mode-alist in the emacs manual:

(setq auto-mode-alist (remove (rassoc 'vhdl-mode auto-mode-alist) auto-mode-alist))

Change to some other mode, e.g.

M-x fundamental-mode RET

or

M-x indented-text-mode RET

re-enable it by entering 

M-x vhdl-mode RET
