;;; eshell-vterm-config --- Settings for the Emacs Shell -*- lexical-binding: t; -*-
;; author Craig Jennings <c@cjennings.net>
;;; Commentary:
;; ESHELL
;; - Eshell is useful as a REPL
;; - Redirect to the kill ring : ls > /dev/kill
;; - Redirect to the clioboard : ls > /dev/clip
;; - Redirect to a buffer : ls > #<ls-output>
;; - Use elisp functions : write your own "detox" command in elisp
;; : then use it in eshell
;; - cd to remote directories : cd /sshx:c@cjennings.net:/home/cjennings
;; : and take all the elisp functionality remotely
;; : including Dired or Magit on a remote server
;; VTERM
;; At the moment, vterm behaves like a real terminal. For most keys, vterm will
;; just send them to the process that is currently running. So, C-a may be
;; beginning-of-the-line in a shell, or the prefix key in a screen session.
;; If you enter vterm-copy-mode C-c C-t or <pause>, the buffer will become a normal
;; Emacs buffer. You can then use your navigation keys, select rectangles, etc.
;; When you press RET, the region will be copied and you'll be back in a working
;; terminal session.
;; ANSI-TERM & TERM
;; I haven't yet found a need for term or ansi-term in my workflows, so I leave
;; them with their default configurations.
