;; File-info
(use-package hydra
  :straight t)

Advising a function in emacs lisp

Thu, 16 Feb 2023 00:00:00 +0000

One of the awesome things that I found when programming in elisp is the advice. For any function, you can advice before, after, around, to it.

When you advice a function A with a function B. Function B will executed before it. This is really interesting and useful.

(advice-add 'funa :before 'funb)

EMACS is a event based program, it has hooks, advices and all that goodness to modify and customize anything. 🪝

You mean Vim?

No matter how much I try EMACS is just too slow for me. Its not snappy as vim. and often times its lagging and hanging and the package management is too slow. Its bluky and full of bloat. Dont get me wrong the base emacs is great. But as soon as I add packages and try to modify it, it keeps getting bulkier and difficult to manage. Whereas vim is snappy. And I can full use tmux and terminal and my hands and safe from injuries. And its comfy.

Open new eshell buffer without closing the current one

Thu, 16 Feb 2023 00:00:00 +0000

I usually run multiple shell instances in terminal. If you already have one eshell buffer open. You can use prefix command to open a new eshell buffer without closing the current one.

C-u M-x eshell

https://stackoverflow.com/questions/2540997/create-more-than-one-eshell-instance-in-emacs/75480565#75480565

Here is my implementation of new eshell buffer / instance.

(defun eshell-new-buffer (args)
  "Create a new eshell buffer."
  (interactive "P")
  (eshell "new")
  )


(global-set-key (kbd "C-c e e") 'eshell)

(global-set-key (kbd "C-c e n") 'eshell-new-buffer)
