This is my current config: set TERM to “xterm”, and fix the otherwise impossible-to-see ANSI blue:

(use-package eat
  :custom
  (eat-term-name "xterm")
  :custom-face
  (ansi-color-bright-blue ((t (:foreground "#00afff" :background "#00afff"))))
  :config
  (evil-set-initial-state 'eat-mode 'emacs)
  (eat-eshell-mode)
  (eat-eshell-visual-command-mode))

I had to use Davmail to get it to work. Now I forward everything, so I don’t run Davmail anymore, but it worked well enough while I needed it: https://lambdaland.org/posts/2023-05-03_email_with_outlook/

Oooooooooohhhhhhhhhh… I can run things like cal or julia and it handles all the escape codes seamlessly. Wow. Totally sold now.

Thank you! That’s helpful. I’m a little confused: what benefit does turning the eshell buffer into an eat terminal give you? Better perf? I’m still new to eshell and stuff.
