This may have been intended for plain text emails, which get quoted in replies by adding a character (usually >) and often a space at the beginning of each line. 70 columns allow 8 levels of quoting on an 80-column terminal (8 > plus a space plus the rightmost column is reserved for a continuation character to indicate that the line overflows). Back in ...

The following three lines of code in this specific order will immediately visibly update the fci-rule-color -- in this example, I am using the color "red". (setq fci-rule-color "red") (fci-make-overlay-strings) (fci-update-all-windows t)

I don't think there's anything wrong with what you're doing. If it works I don't see any obvious pitfalls. That said, it's not the usual way to apply mode-specific settings. This is usually done with a mode-hook. For example, I have the following in my init: (defun my-org-src-mode-hook () (setq fill-column 65) (auto-fill-mode t)) (add-hook 'org-src-...

Here's the complete end-to-end solution I ended up with based on lawlist's answer. (defun my:color-is-closer-to-white-p (color) "Returns t if COLOR is closer to white than black." (< (color-distance color "white") (color-distance color "black"))) (defun my:get-subtle-color-from-background (percent-difference) "Gets a shade PERCENT-DIFFERENCE ...

You didn't mention which major mode this happens in, but I can see the problem using c-mode. Here is an (abridged) backtrace which you can get after setting debug-on-error: Debugger entered--Lisp error: (args-out-of-range #<buffer xx> 66 66)... buffer-substring(#<marker at 66 in xx> #<marker at 66 in xx>) yas--field-text-for-display([...

Aha, I have the solution! Put this somewhere in your .emacs/.emacs.d/init.el file: (define-advice current-fill-column (:filter-return (rtn) protrusion) "Advice to allow hanging punctuation when filling text." ;; Get the character after the proposed cutoff point (let ((end-char (char-after (1+ rtn)))) (if (and end-char ;; Check if ...

temp-buffer-show-hook should help. That's where help-mode-finish is called, for instance. It is used in with-help-window and with-temp-buffer-window, which are used to display Help windows.

I'd do this with a combination of re-search-forward and replace-match on subgroups (in this case the spaces just before and after *. You can simplify the regular expression if you don't want match the timestamps. (defun add-dashes-to-line () (interactive) (save-excursion (beginning-of-line) (when (re-search-forward (rx "-" space ...

Based on @Drew's answer, I ended up doing this: ;; function to get window width (defun my-get-window-width () "Get width of current window in." (/ (window-body-width nil t) (window-font-width))) ;; function to set the fill column (defun my-auto-set-fill-column () "Set fill-column to window width." (let ((inhibit-message 1)) (set-fill-...

I had comment-auto-fill-only-comments set to t. Since Magit commit buffer supports comments, it won't auto-fill. (use-package git-commit   :ensure nil   :preface   (defun me/git-commit-set-fill-column ()     (setq-local comment-auto-fill-only-comments nil)     (setq fill-column 72))   :config   (advice-add 'git-commit-turn-on-auto-fill :before #'me/git-...

This is a known issue with org-mode and fci-mode. See here and here for a discussion and some suggested solutions. Personally, I found the cure to be worse than the symptom and it didn't quite fit with what I wanted. I have instead found an alternative which works with org-mode and still provides me with the sort of information I was after with fci-mode. I ...

Here's a workaround that displays fci when its needed. Note that while it takes horizontal scroll into account, I couldn't find a hook to run when horizontal scrolling changes. if fci-rule-column isn't set it uses the value for fill-column. (defvar i42/fci-mode-suppressed nil) (make-variable-buffer-local 'i42/fci-mode-suppressed) (defun fci-width-...

Here's the answer to a post where I struggled with a similar problem concering visual-line-mode. @YoungFrog describes how visual-line-mode works pretty well in a comment. Long story short, visual-line-mode involves only 'soft' new lines, i.e. it does not actually edit the formatting of your text at all, it only makes it look like your text is a certain line ...
