multibyte languages rendering is strange(9.0.472) #1296
Comments
I checked that the bug do not occur in version 9.0.0065. |
I have a test for various characters in my As far as I remember (as it was discussed before at least), the rectangle was calculated from the main font and to other fonts were cut as they were wider. newer implementation just doesn't cut the character size from fallback font and you see a mix. Long story short, you can control if main font is monospaced, but you can't control spacing from another fonts. Also you can't check and control all characters in a whole document you edit as it could be way bigger than you observe. (I advocate here to Vim's implementation, where what you see on a screen is what Vim renders, and it renders a very small portion of it. Because of clever implementation, Vim can easily edit very huge files without a penalty) I personally prefer this implementation than a lot of font and document hacks. In screenshot below, rightmost right arrow on a line above emoji takes the same width as Thanks to a good implementation, movement works "visually" correctly: despite every japanese hieroglyph is a single character, when I move up from the second, my cursor will move to |
I described how I remember development of MacVim and my personal opinion. It could be different from yours as I don't type often in other languages than European. I even don't have special fonts for eastern languages |
I can't really reproduce this. Some questions for you @shikato:
I don't think any code in the relevant parts had changed in the release so there shouldn't have been much change, so I'm a little surprised to see any rendering differences. |
The width of a character is always either 1 or 2 in Vim. It's calculated by Vim (not MacVim), and not determined by the font at all. In fact, if the two (Vim versus font) don't agree, that's usually when you would get weird artifacts. |
Thank you for describing this, I took it from "cut emoji" issue. |
5The explanation is very difficult, so I recorded a video. |
@shikato yes, video explained issue quite better How did you install MacVim? I have MacVim installed from GitHub releases and have no such issue via copy and paste and direct input (I installed standard japanese keyboard for the test via system preferences) |
@eirnym I found a tweet, maybe it is same issue, too. |
@shikato , out of curiosity, why are you setting Core Text renderer to off? As the description there says, this is deprecated, meaning that using MacVim without Core Text renderer is no longer supported (and we no longer fix bugs / glitches associated with it). I still exposed the option for now in case we need to debug issues, but it would be removed in the near future with no option to turn it off. Can you just use it with Core Text renderer on? What feature do you find missing? |
I'm still curious what broke though, so I'll take a look, but you should probably assume that Core Text Renderer off will break at any time. |
I think this was caused by #1287 just for reference. |
This was previously broken by macvim-dev#1287 as I did not update the new constants' values. Fix macvim-dev#1296
@ychin I have a hazy memory, I think the reason was to avoid similar issue. I think the issue doesn't occur in current version, so I can enable Core Text renderer. Thank you for confirming. |
Right. Yes please enable Core Text renderer. I will fix this bug anyway since it's easy to fix, but I should probably just remove the option to unset Core Text renderer in a future release to avoid stale settings like this leading to obscure bugs. Feel free to file additional issues if you find other issues. |
This was previously broken by macvim-dev#1287 as I did not update the new constants' values. Also, make strikethrough work in it. The non-CoreText renderer is essentially deprecated and will be removed in near future, but for now just fix up the straggling bugs since this is easy to do so. Fix macvim-dev#1296
Thank you for referring to my tweet. @ychin In my environment, with that option enabled, MacVim (I don't remember the version) did not display properly in the former Big Sur environment, such as the display blinking, so I disabled it. |
I see. Thanks for the context. I'm probably going to remove the option to unset the core Text renderer in the future. If we run into more displays issues we will just have to fix them instead of allowing a poor workaround (I still think it was likely due to the MacVim version being old and didn't have the latest fixes to the renderer). |
Updated to Vim 9.0.1276 Features ==================== Dictionary lookup -------------------- You can now use Force Touch or Cmd-Ctrl-D to look up definitions of word under the cursor (or selected text in visual mode). This will also preview URLs, and support data types such as phone numbers and addresses. #1312 #1313 This feature can also be invoked programmatically from VimScript (see `:h macvim-lookup`). #1315 Tool bar / Touch Bar / menu icons -------------------- You can now use SF Symbols for Tool bar and Touch Bar icons, including using different symbol styles such as "palette" or "multicolor". Menu items can now also use the `icon=` syntax to specify icons as well. See `:help macvim-toolbar-icon` for details. #1329 The default tool bar also has updated icons to look similar to SF Symbols used by newer macOS versions. #1214 by @sfsam Window management actions -------------------- There are new `macaction`'s for managing the MacVim window. The new `zoomLeft`/`zoomRight` actions allow you to pin the window to the left/right of the screen, and there are also new actions for interacting with Stage Manager (requires macOS 13+). See `:h macvim-actions` for details. #1330 Pre-release updates / Sparkle 2 -------------------- MacVim now supports pre-release software builds. It's sometimes hard for us to release frequent updates due to the desire to pick a stable upstream Vim version, needing to test the release on multiple OS versions, making sure there aren't half-complete or buggy features, and other reasons. This new feature now allows us to push pre-release beta builds out in a more frequent fashion, which could be useful if there are particular features or fixes that you would like to try out before the next official release. Pre-release builds will be released depending on bug fixes and features instead of a fixed cadence. Do note that these pre-release builds may not be as well-validated and may have half-baked features. If you are using the built-in auto-updater to update MacVim, you can turn this on by going to Advanced settings pane, and enable "Enable pre-release software updates". This feature is only available for macOS 10.13 or above. The auto-updater has also been updated from Sparkle 1.27.1 to 2.3.0 for 10.13+ builds. Legacy (10.9-10.12) builds are still using Sparkle 1. See #1332. New Vim features -------------------- New `smoothscroll` option allows you to scroll through a long wrapped line (using Ctrl-E or mouse wheel) without immediately jumping to the next line. (v9.0.0640) `splitscroll` option has been renamed `splitkeep`, with more flexibility than before. (v9.0.0647) Sound playback on macOS is now supported. You can use `has('sound')` to check. See `help sound` for details. (v9.0.0694) Terminals now support `:confirm` for `:q`, etc, which also means MacVim's Cmd-W will work properly for terminal windows. (v9.0.0710) Virtual text had numerous bugs fixed. General ==================== Legacy build for 10.9 - 10.12 -------------------- Per a previous announcement (#1271), the default MacVim binary will now require macOS 10.13 or above. Users of macOS 10.9 - 10.12 can use a separate "legacy" build which will still be supported. The legacy binary will still have the latest versions of Vim and be supported, but may not have all the latest features (e.g. pre-release builds). If you are using the auto-updater (Sparkle) to update MacVim, it should "just work" and find the best version for you. If you are downloading MacVim from the website, there is also a link to download the legacy version marked for 10.9+ as well. If you download the normal binary marked for 10.13+ from the website, it won't work on these older macOS versions. See #1331. Fixes ==================== CoreText Renderer clipping and rendering bugs -------------------- Unicode characters with multiple composing characters (e.g. "x⃗") will now render correctly. #1172 Texts (e.g. Tibetan, Zalgo texts) that are taller than the line height will no longer be clipped inappropriately. You can use a new setting `MMRendererClipToRow` to re-enable clipping if the tall texts are distracting. #995 / #1356 Tab crash -------------------- Fixed a crash when opening new tabs that seems to only occur in macOS 13 Ventura. #1333 Other bugs -------------------- - Fixed non-native full screen not working well with the notch on newer MacBook's when set to not show menu bar. You can also use `MMNonNativeFullScreenSafeAreaBehavior` to force MacVim to use the notch area as well if you don't mind some content being obscured. Note that the previous release also claimed it fixed this, but because the binary was built against an old macOS SDK (Big Sur), the fix did not work in the binary release. #1261 - Allow "Open untitled window: never" and "After last window closes: Quit MacVim" to be set together again. Added safeguards to make sure doing so won't immediately close the app. #1338 - Edit.Cut / Copy menu items will now be properly disabled when there isn't selected text. #1308 - Fixed potential `:emenu` crash when the menu is associated with an action in a non-valid mode. #1305 - Fixed bug where just bringing up the right-click (or the MacVim→Services) menu would somehow copy the selected texts to the system clipboard. #1300 - Fixed a Japanese input method bug where using left/right arrow to move to a different section of the input text would previously result in the candidate list not showing up at the correct position. #1312 - Fix non-CoreText renderer not handling text styles like strikethrough correctly (note: this renderer has been deprecated for a while and you should not use it). #1296 - This release uses an older sh/bash syntax file because the latest one in Vim has a bug. #1358 Misc ==================== New settings: - "No drop shadows" (Appearance). #1301 - "Treat Ctrl-click as right-click" (Input) (#1326). This was previously configurable via command-line, but now also possible in the settings pane under the new "Input" category. "About MacVim" now reports the version number in a clearer way with clearly specified release number vs Vim version. Known Issues ==================== Printing -------------------- Printing using File→Print or `:hardcopy` is currently not working under macOS 13 Ventura due to its removal of PostScript support in the Preview app. This will be fixed in a later release. See the issue for workarounds. #1347 Scripting ==================== - Scripting languages versions: - Perl is now built against 5.30, up from 5.18. - Ruby is now built against 3.2, up from 3.1. Compatibility ==================== Requires macOS 10.9 or above. (10.9 - 10.12 requires downloading a separate legacy build) Script interfaces have compatibility with these versions: - Lua 5.4 - Perl 5.30 - Python2 2.7 - Python3 3.10 - Ruby 3.2
