From: Mikhail Efremov <jakutenshi <at> gmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 28.2; global-display-line-numbers-mode in org file do strange identation when headers are folded Date: Sun, 02 Jun 2024 15:10:46 +0600
Hi, Emacs devs, * Description There is an issue with not so large org files with global-display-line-numbers-mode is toggled on. You may reproduce it: 1. ~emacs -Q~ 2. open an org file with 1000+ lines of different headers' layers unfolded. 3. ~M-x global-display-line-numbers-mode~ 4. Check that unfolded headers on lines 999-1000 are indented fine: - numbers are right-aligned; - same-level headers are indented equally with the same indent width relative to line numbers. 5. Fold all headers with the property: on the screen of the buffer there are single-, two- and three-digits lines' numbers are presented. Then, you should see the picture like this: 1 * header1 24 * header2 132 * header3 1019 * header4 The same behavior is on ~emacs -nw -Q~. The issue is valid also on built from sources emacs: GNU Emacs 29.3 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.38, cairo version 1.16.0) of 2024-04-08 * Motivation This behavior on the one hand constantly shifts left-to-right-and-vice-versa the buffer's text and also confuses with headers' identation level. * Definition of Done After the steps of reproducing the desired view is: 1 * header1 24 * header2 132 * header3 1019 * header4 * Details of implementation I guess there is a problem with line's mode algorithm, from my side it looks like it taking into account only 1 digit difference for an identation, then if there is 2 or more digits differnece, then all after the first-digit diff identations are broken. The posible solution is to count total lines number and reserving line's numbers side width from total lines count number's width. Thank you a lot! Sincerely, Mikhail Efremov. --- In GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, cairo version 1.16.0) of 2023-05-14, modified by Debian built on x86-ubc-01 Windowing system

Consider also customizing display-line-numbers-grow-only to a non-nil value. > * Details of implementation > > I guess there is a problem with line's mode algorithm, from my side > it looks like it taking into account only 1 digit difference for an > identation, then if there is 2 or more digits differnece, then all > after the first-digit diff identations are broken. No, that's not what happens. The problem is that the required width of the line-number display needs to be calculated when the window is about to be shown on display or redisplayed due to scrolling etc. At that time, the display-engine code which does this calculation cannot know up front how many lines are hidden by 'invisible' text properties and overlays, something that Org uses a lot, and therefore cannot correctly estimate the largest line number to be shown. So its estimation of the maximum number of the line in the window are incorrect in those cases. Customizing display-line-numbers-width-start fixes that problem, for a price of a slightly slower initial display of the window. It could still fail if you add a lot of lines to the buffer, in which case toggling display-line-numbers-mode off and on again should fix it. > The posible solution is to count total lines number and reserving > line's numbers side width from total lines count number's width. That's exactly what the above user option does, when non-nil. There's no bug here.
