If I’m understanding you right, you’re trying to make a keybinding that will act like you typed C-u M-x grep <ENTER>. Try this: (global-set-key (kbd “C-c m g”) (lambda () (interactive) (setq current-prefix-arg ‘(4)) ; C-u (call-interactively ‘grep))) Although I would probably make a named function for this: (defun grep-with-prefix-arg () (interactive) (setq current-prefix-arg ‘(4)) … Read more

Does shell-command-to-string meet your purpose? For example: (shell-command-to-string “/bin/echo hello”) Hope this helps.
Personally, I use the following workflow: run on a C-c C-c m to run Markdown on the current buffer and preview the output in another buffer. move to html-mode on this other buffer (M-x html-mode) hide the html tags to display something close to the output (M-x sgml-tags-invisible) Then every time you want to refresh … Read more

there is a variable that you can add to your .emacs (setq evil-want-C-u-scroll t) it needs to appear before the call to (require ‘evil).
You might want to rebind C-x C-b to invoke buffer-menu rather than list-buffers: (global-set-key “\C-x\C-b” ‘buffer-menu)
From the documentation: (get-buffer name) Return the buffer named name (a string). If there is no live buffer named name, return nil. name may also be a buffer; if so, the value is that buffer. (get-buffer-create name) Return the buffer named name, or create such a buffer and return it. A new buffer is created … Read more

Some of the major differences: ELisp traditionally used dynamic scoping rules; Common Lisp uses lexical scoping rules. With dynamic scoping, a function can access local variables declared in calling functions and has generally … Read more
