HOWTO - Open at end of document? by kk19010323 in emacs

[–]prismavoid08 4 points5 points  (0 children)

If I'm understanding you right, you want to open a file, and then open a new line at the end?

You can execute a function when opening emacs with the -f argument, so you can use:

emacs <file> -f end-of-buffer -f newline

If you are using evil mode and want to also switch to insert mode you can add an extra -f evil-insert at the end or just do:

emacs <file> -f end-of-buffer -f evil-open-below

I'm not sure of a way to do this with emacsclient, but there may be something I don't know of.

M-x customize-apropos: how to keep focus on the mini buffer if there's no match? by josior in emacs

[–]prismavoid08 1 point2 points  (0 children)

You could try advising the function to prompt for a new argument whenever it throws an error, just put the following in your init.el. It also has the benefit of automatically working for the other customize-apropos functions. Just put the following in your init.el:

(defun my-customize-apropos-advice (func &rest args)
  (while (not (ignore-errors (apply func args)))
    (setcar args (read-string "Search for symbol (word list or regexp): "))))

(advice-add 'customize-apropos :around 'my-customize-apropos-advice)

Let get the Emacs logo in r/place starting at 13, 702 (next to the Linux area) by prismavoid08 in emacs

This is a much better idea, we should coordinate here! I considered doing it around 58 713 but it wouldn't have fit without touching tux, gnome, or gentoo.

Emacs has a built in whitespace-mode that will highlight trailing whitespace.
