If I modify my .emacs file I usually call eval-buffer to apply all changes to existing buffers without restarting emacs. Now I have the following lines to invoke helm-mini each time emacs starts:

(if (< (length command-line-args) 2) 
(setq initial-buffer-choice (car (helm-mini)))
)

The problem is that if I call eval-buffer it displays a helm mini buffer each time.

How can I make emacs exclude those lines when calling eval-buffer or alternatively, how can I change the code lines above such that the problem doesn't occur anymore?

  • Use eval-region instead and select the region to be evaluated. Or, comment out what you don't want to be evaluated when calling eval-buffer. Or, simply put in conditions to prevent certain portions of code from being evaluated -- e.g., (defvar foo nil) -- and set the variable to either t or nil -- (if foo . . .). – lawlist Aug 19 '16 at 22:03

If you want to call (helm-mini) after Emacs has started up, you can add it to emacs-startup-hook in your init file:

(add-hook 'emacs-startup-hook #'helm-mini)

This way Emacs will run this function upon startup, but not upon re-evaluation of your init file.

  • When 'foo is compiled, it's fine if foo it not a function. When #'foo is compiled, Emacs will warn about foo not being a function. – zck Aug 20 '16 at 16:43
