MacVim r181

Updated to Vim 9.1.1128

This update contains a completely new GUI tabs implementation by @sfsam!
It also contains lots of small fixes for window resizing and full screen
mode that aims to make using MacVim feel rock solid and stable.

Defaults Change
====================

New settings defaults related to window sizing #1528:

- "Smoothly resizes window" is now on by default. MacVim's window will
  now resize smoothly instead of snapped to the size of the character
  grid.
- Vim's `guioption` now has `k` set by default (`:h go-k`). This
  prevents MacVim's window size from changing unnecessarily when
  showing/hiding tabs or changing font size.

These should align MacVim better with how other apps work and integrate
better with OS window management, including macOS 15 Sequoia's window
tiling feature.

Features
====================

Tabs
--------------------

MacVim has a new tabs implementation! The old version (PSMTabBarControl)
is not maintained and lacks features such as overflowing tabs and
customizable colors. The new tabs will overflow horizontally and are
scrollable. They also animate when tabs are closed or moved, respect
system settings such as right-to-left locales and high-contrast modes,
and are designed to fit within the currently selected Vim colors.

There are a few ways to customize the colors of the new tabs, under the
"Appearance" settings pane. MacVim defaults to an "Automatic colors"
mode which tries to pick sensible colors automatically based on the
current foreground/background colors. However, you can also configure it
to simply use the tab colors specified by the Vim color scheme (some
color schemes will work better than others depending on their choice of
colors). Another new option is "Use tabs background color" which when
combined with "Transparent title bar" allows the title bar and tabs to
look like a single cohesive whole.

Relevant work:

- #1120 (by @sfsam)
- Also: #1535 / #1536 / #1537 / #1538 / #1539 / #1557 / #1558 / #1560

New Vim features
--------------------

- new bundled color scheme:
    - unokai (vim/vim#16443)
- new bundled optional plugins (use `packadd` to enable them):
    - helptoc: Use `:HelpToc` to show an interactive table of contents
      for Vim help, man pages, Markdown files, and terminal.
      vim/vim#10446
- new options:
    - `set diffopt+=linematch:{n}`. Matches lines better when in diff
      mode. v9.1.1099
    - `findfunc`. Customizes `:find` and other commands. v9.1.0831
    - `set completeopt+=preinsert`. Preview inserted text in completion.
      v9.1.1056
    - `messagesopt`. Allows customizing hit-enter behavior. v9.1.0908
- new functions:
    - `getcellpixels()`. Query the pixel size of a character cell in the
      grid. v9.1.0854 / #1554 / #1555
- Vim tutor has a new interactive plugin (v9.1.0836). There is also now
  a chapter 2 (vim/vim#5729).

Misc New Settings
--------------------

- "Open untitled window" (General) has a new option to only open on
  MacVim re-activation. #1509
- "Show document icon at title bar" (Appearance). Previously MacVim
  implicitly hid the document icon when using transparent title bar.
  This is now customizable. #1510

General
====================

- The MacVim dmg installer has a new design. Courtesy of @jasonlong.
  #1540 #1545
- Legacy builds (macOS 10.9 - 10.12) are no longer built by GitHub
  hosted runners, due to GitHub's deprecation of old runners. They are
  now built by a custom self-hosted VM instead. In the future we hope to
  set up reproducible builds (#1506) so it will not matter who's
  building the app as it would be verifiable. #1559
- "Nightly" build: We now build a dmg installer for every commit. This
  allows for trying out the latest developmental version of MacVim, but
  note that the app will not be signed / notarized, and it will not be
  as polished as official release/pre-release builds. See
  [wiki](https://github.com/macvim-dev/macvim/wiki/Installing) for
  instructions. #1532

Fixes
====================

Apple "Intelligence" Writing Tools
--------------------

macOS 15 Sequoia's Apple "Intelligence" Writing Tools should work
correctly with MacVim now. To use it, select some text, right click to
show menu, and then select the "Writing Tools" sub-menu. As part of this
fix, the integration with the "Services" menu now works more reliably as
well. You can select texts in blockwise visual mode and select a service
and MacVim will try to place the new texts back to the blockwise
selection if possible. #1552

Window resizing and full screen
--------------------

- Flicker begone: Changing font size, showing/hiding tabs or scroll
  bars, or entering non-native full screen should no longer cause MacVim
  to flicker. Previously there could be a momentary but
  distracting/annoying stale image that flashes briefly. #1547 #1549
- Fixed issue where resizing MacVim window would occasionally cause Vim
  to be stuck in a stale wrong size. #1518
- Non-native full screen now supports `blurradius` option. #1546
- Fixed window size not always restoring correctly when exiting full
  screen. Non-native full screen also works more reliably in
  multi-monitor setup. #1525
- Fixed non-native full screen mode when using an external monitor with
  a MacBook with a notch, and having the "Show menu bar in non-native
  mode" option set. Previously MacVim would sometimes miscalculate the
  menu bar height in the second screen. #1548
- Fixed misc issues with non-native full screen's interaction with
  `fuoptions` and also the `transparency` setting, and rare crash. #1521

Other Fixes
--------------------

- Fixed issue where changing font size (using Cmd =/-) with guifont set
  to "-monospace-" would result in guifont being changed to a confusing
  name like ".AppleSystemUIFontMonospaced-Regular". #1544
- "MacVim Website" menu item now goes to the updated URL. #1524
- What's New page now allows changing font size (using Cmd =/-), and
  showing table of contents. #1561 #1562
- Dark mode documentation is now a bit clearer on `v:os_appearance`.
  #1511
- Using dictionary look up on selected texts (by right clicking and then
  selecting "Look Up" in the pop-up menu) is now more resilient as it
  uses Vim's native `getregion()` to determine the selected texts. #1508

Scripting
====================

- Scripting languages versions:
    - Ruby is now built against 3.4, up from 3.3.
    - Perl is now built against 5.34, up from 5.30.

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 5.34
- Python2 2.7
- Python3 3.9 or above
- Ruby 3.4
