Execute command on every start except you load a file from commandline

Question

To load helm-mini every-time when emacs starts, I use the following line in my .emacs file as suggested in https://emacs.stackexchange.com/a/26402/2323

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

This in particular avoids that helm-mini is loaded if I execute eval-buffer after changing my .emacs-file.

However there is another problem with it: If I start emacs from command line like emacs myfile.tex, emacs opens the file myfile.tex but also opens helm-mini. How can I make emacs not to load helm-mini in this case?

Answer 1

The variable command-line-args contains the command line ("emacs") when there are no arguments and ("emacs" "myfile.tex") when you invoke it for myfile.tex. The simplest thing I can think of doing here is to check the length:

(when (< (length command-line-args) 2)
  (add-hook 'emacs-startup-hook #'helm-mini))
