Yep, that's a possible solution, but I feel that it is such a basic functionality, emacs should be able to solve this question without using such workarounds. But this is just an intuition, feel free to ignore it :) Column-enforce-mode can be already slow for large files, if it had to do this copy all the time it would be even slower. >> Regarding how to fix this problem: wouldn't it make sense to stop >> calculating the width at the first "\n" in the displayed string? > Stop calculating and do what? move-to-column doesn't just calculate, > it should move point to some place. Where do you want to move point > in these cases? I understand that solving this problem if we want to stick with the current idea of move-to-column (meaning that it has to consider display properties), is hard, or even we can say that there are no good solutions. But ideally, it should move the cursor to the closest possible location in the same visual line. As far as I understand the intention of this function. But for my problem, I don't think that this is the way to go. Column-enforce-mode should calculate columns without considering properties. I'd be good if emacs gave an out-of-box solution for this (without using copying), but if it doesn't, it's also fine.

But it's impossible to do that when the newline comes from a display property. So the correct behavior is not "undefined" in this case, it is just impossible to achieve.

Is there a function which does that? I noticed this problem because how indent-bars interacts with column-enforce-mode (https://github.com/jordonbiondo/column-enforce-mode). column-enforce-mode uses move-to-column to mark long lines. And because the display property with "\n" basically joins neighboring lines, column-enforce-mode marks lines incorrectly. I think it should only consider what's in the buffer, and ignore all rendering related properties. Is there a way to accomplish this? Regarding how to fix this problem: wouldn't it make sense to stop calculating the width at the first "\n" in the displayed string? At least, it would fix this problem, as far as I understand. Not sure if it breaks anything. But supposedly nothing should depend on the exact behavior of column calculations, if the displayed string contains characters after the first "\n" (because it's kind of undefined what the width of a multi-line string is) On 8/1/23 14:25, Eli Zaretskii wrote: > tags 64988 notabug wontfix > thanks > >> Date: Tue, 1 Aug 2023 12:53:57 +0200 >> From: Herman <at> debbugs.gnu.org, Géza <geza.herman@HIDDEN> >> >> If there is a text with display property in a buffer, then >> move-to-column can move across lines. >> >> Repro: >> * emacs -Q >> * in the scratch buffer, move the cursor to the top, and put an empty >> line at the beginning of the buffer >> * execute 'M-: (put-text-property 1 2 'display "line\n")' (note: it's >> likely that the "\n" causes the problem) >> * notice that the empty line becomes "line" >> * while the cursor still on the first line, execute 'M-: (move-to-column >> 20)' >> >> The last command will move the cursor to the next line at column 16, >> instead of staying at the first line. >> >> Note: I noticed this problem while using this package: >> https://github.com/jdtsmith/indent-bars. >> >> The problem doesn't happen with emacs 28, this is the commit that >> introduced the issue: >> >> 4243747b1b8c3b7e3463822804b32e83febe2878 Fix 'current-column' in the >> presence of display strings > This is a known issue, but it is not a bug, at least not one we know > how to "fix".

In general, move-to-column cannot work correctly when display strings with embedded newlines are involved, because Emacs cannot place the cursor at the newline in the middle of such a display string. The commit to which you point fixed current-column to correctly report the column where such display strings are involved, at least in the important cases. That move-to-column changed behavior in those cases is unfortunate, but I couldn't find any sensible way of dealing with these cases, because the correct result -- setting the cursor after the newline embedded in the display string, because column 20 doesn't exist on that line -- is impossible. (The result that you expected, which was what Emacs 28 did, i.e. for the cursor to stay at buffer position 1, is also incorrect, since that position is column 1, not column 20 and not the last column visible on that line.) So I'm sorry, but unless someone comes with an idea for how to handle these situations in a sensible way (and I thought long and hard about it, but couldn't find such ideas), this will remain a limitation of move-to-column, and one of the complications introduced by display strings with embedded newlines in general. The affected packages will have to adapt to this change in some ways. Since the original code also produced incorrect results, just different incorrect results, I don't see this as a serious problem, just as a bug that wasn't fixed, but changed its buggy behavior.

Repro: * emacs -Q * in the scratch buffer, move the cursor to the top, and put an empty line at the beginning of the buffer * execute 'M-: (put-text-property 1 2 'display "line\n")' (note: it's likely that the "\n" causes the problem) * notice that the empty line becomes "line" * while the cursor still on the first line, execute 'M-: (move-to-column 20)' The last command will move the cursor to the next line at column 16, instead of staying at the first line. Note: I noticed this problem while using this package: https://github.com/jdtsmith/indent-bars. The problem doesn't happen with emacs 28, this is the commit that introduced the issue: 4243747b1b8c3b7e3463822804b32e83febe2878 Fix 'current-column' in the presence of display strings
