Since eshell buffer is just a regular emacs buffer, we have all of the emacs power at our disposal. In part 3 of my post, I briefly alluded to multiple terminal management by just using few lines of elisp and all without using any third party packages. I am posting the main elisp function for posterity here:
(defun krun (cmd) (interactive (list (ido-completing-read "Enter cmd to run (append ##name for buffer name): " (let ((history nil)) ;; We have to build up a list ourselves from the ring vector. (dotimes (index (ring-length keshell-history-global-ring)) (push (ring-ref keshell-history-global-ring index) history)) ;; Show them most-recent-first. (setq history (nreverse history)))))) (let* ((cmds (split-string cmd "##")) (tag (or (-> cmds second) "kshell")) (buff-name (-> tag s-chomp s-trim))) (kshell cmd buff-name)))
The above function (along with those from the previous post) will allow you to do following:
- Start a new shell with a specific name by just appending ##buffer-name after the command
- Run a command from history or new command in a dedicated eshell buffer, which defaults to kshell. You can override as any name you want.
- Use all hotkeys, interactive lisp functions as you would for regular emacs buffer. For example, you can do buffer switching, ibuffer management, isearch, protect a buffer from being killed, etc.
Following demonstrates above cases I am talking about:
