A straight-forward way to disable `truncate-lines` in org-mode display

[Zalewa]

Why I want truncate-lines nil:

Because the replies are output like this and I can't read them:

With truncate-lines nil it's not much better to be honest, but the text is at least visible:

How I wanted to do this:

I figured that since there is copilot-chat-org-prompt-mode-hook then I can just hook into it and disable truncate-lines, but it doesn't work because polymode overwrites this. I traced where the truncate-lines variable is changed and first my hook would disable it, then polymode would happily turn it back on.

There is a way to work around this by hooking into org-mode-hook instead, but it feels too convoluted for me and prone to destabilization.

Steps:

Use this minimal init.el:

;; Setup the package archives
(require 'package)
(add-to-list 'package-archives '("melpa-stable" . "https://stable.melpa.org/packages/") t)

;; A straight-forward way to disable truncate-lines in Copilot Chat Org prompt mode.
;; The catch is... it doesn't work.
(defun my/turn-off-truncate-lines ()
  (message "Disabling truncate-lines")
  (setq-local truncate-lines nil))

(use-package copilot-chat
  :ensure t
  :defer t
  :hook (copilot-chat-org-prompt-mode . my/turn-off-truncate-lines))

1. M-x copilot-chat-display
2. Ensure the chat buffer is an org-mode buffer.
3. C-h v truncate-lines - it will say that the value is t.
4. Inspect the Messages buffer and see that "Disabling truncate-lines" is there.

Workaround:

Hook into org-mode-hook instead and check the buffer name. Also, pray that the buffer name won't change in future releases:

;; Setup the package archives
(require 'package)
(add-to-list 'package-archives '("melpa-stable" . "https://stable.melpa.org/packages/") t)

;; The convoluted way that actually works:
(defun my/turn-off-copilot-org-truncate-lines ()
  "Disable `truncate-lines' in Copilot Chat buffer."
  (when (string-match-p "Copilot Chat" (buffer-name))
    (message "Disabling truncate-lines in Copilot Chat buffer")
    (setq-local truncate-lines nil)))

(use-package copilot-chat
  :ensure t
  :defer t
  :hook (org-mode . my/turn-off-copilot-org-truncate-lines))

Here's my full init.el for reference:

I see the problem.
It did not happen for me because I have visual-line-mode enabled for org files.
Hooks seem to be useless, even those added by polymode. I'm looking for a way to apply ``visual-line-mode` only for text and not for code blocks so I'm going to investigate.
