In macOS 13 Ventura, the general terminology of "Preferences" has been
renamed to "Settings". The main menu's "Preferences…" item is
automatically renamed to "Settings…" by the OS when building against the
macOS 13 SDK, but we still need to update documentation to match.
Add a new Vim script function `showdefinition()` that allows Vim script
to call back to macOS's data lookup feature and show the definition /
URL preview / etc for any text, at a designated row/col position. If the
row/col are not provided this function will just show it at the cursor.
Also, add a new autoload/macvim.vim for utility functions to call
showdefinition() for selected texts and the word under cursor. Make a
new right-click popup menu "Look Up" call that when there are selected
texts in visual mode to make the lookup functionality easier to access
for users without a trackpad (since Ctrl-Cmd-D is a little obscure and
unwieldy to use). For the utility functions, it was a little hard to
determine how to get the text under visual selection without yanking (we
don't want to pollute the register here), and just implemented a
function to take care of all the edge cases including visual/block/line
modes and selection=exclusive. It could be useful in other situations.
As a side refactor, change the message handler in MacVim from if/else to
switch case. In optimized builds, they both essentially optimize to the
same thing, but for debug builds, the if/else statements have to step
through one by one, and switch case just makes more sense for a giant
message ID lookup like this.
Part of Epic #1311
This automatically uses NSDataDetector to detect special data around the
lookup cursor position, and if found, will manually call showDefinition
instead of letting the OS do it for us (honestly, this feature should be
built-in to the OS instead of such manual work). Right now only doing
address/phone number/URL (URL has priority), because we don't have
built-in definition support for the other types like flight info and so
on. This also only works for what is drawn on-screen only, because as
usual, MacVim doesn't have access to the native text storage, unless we
rely on lots of callbacks back-and-forth (which is possible, but
annoying to implement).
Doing data lookup (e.g. Ctrl-Cmd-D) on top of a selected text now
properly look up the entire selected range (e.g. "ice cream", instead of
just "ice" or "cream"). This would have come by default if we could
implement NSTextInputClient's selectedRange properly but since MacVim
doesn't have access to the internal Vim buffers easily this is easier
said than done. As such, we have a custom implementation where if we
detect a lookup event, manually detect that we have the mouse cursor on
top of selected text and show the definition for that manually.
Also fix a minor issue in text input client so that the baseline is now
reported correctly for certan font size comboes, as our fontDescent is
rounded up for some reason.
Problem: Wrong cursor position when using "gj" and "gk" in a long line.
Solution: Adjust computations for the cursor position and skipcol. Re-enable
tests that pass now, disable failing breakindent test.
Problem: Mouse column not correctly used for popup_setpos.
Solution: Adjust off-by-one error and handle Visual line selection properly.
(Yee Cheng Chin, closes#11356)
Problem: Lisp word only recognized when a space follows.
Solution: Also match a word at the end of a line. Rename the test. Use a
compiled function to avoid backslashes.
Problem: Quickfix listing does not handle very long messages.
Solution: Use a growarray instead of a fixed size buffer. (Yegappan
Lakshmanan, closes#11357)
Problem: Cursor position invalid when scrolling with 'smoothscroll' set.
(Ernie Rael)
Solution: Add w_valid_skipcol and clear flags when it changes. Adjust
w_skipcol after moving the cursor.
Problem: Use of strftime() is not safe.
Solution: Check the return value of strftime(). Use a larger buffer and
correctly pass the available space. (Dominique Pellé, closes
#11348)
This adds support for looking up data under the mouse cursor. Usually it
will bring up a dictionary, but other times it could be a Wikipedia
article, Siri knowledge, etc. Apple doesn't really have a good name for
it, other than "looking up data", "quick look" (a confusingly similar
name with the other Quick Look OS feature), or "show definition". You
can activate this by doing Ctrl-Cmd-D when the mouse is over a cursor.
If you have a trackpad, you can also either activate this using Force
click or three-finger tap (depends on your system preference settings).
Note that for Force click, this could potentially make it impossible to
use the MacVim `<ForceClick>` mapping in Vim, which allows you to map a
force click to a Vim command (#716). This is handled by having a new
setting (under a new "Input" preference pane which will have more
populated later) that allows you to choose whether to use Force click
for data lookup or Vim's `<ForceClick>` mapping. If you have configured
to use three-finger taps though this setting wouldn't do anything, and
`<ForceClick>` is always send to the Vim mapping.
Also, this is lacking a lot of features that a normal macOS application
would get, e.g. looking up selected texts (e.g. if you have "ice cream",
you may want to select the whole thing to look up the phrase, rather
than just "ice" or "cream"), data detector, and much more (e.g. custom
API support). They will be done later as part of #1311.
Technical details below:
The way the OS knows how to look up the data and present it is by
talking to the NSTextInput/NSTextInputClient. Previously MacVim
implemented NSTextInput partially, and didn't implement the critical
firstRectForCharacterRange:actualRange and characterIndexForPoint:
functions. First, in this change we change from NSTextInput to
NSTextInputClient (which is the newer non-deprecated version), and
implement those functions, which allows the OS to query the text
storage.
By default, the OS sends a quickLookWithEvent: call to us whenever the
lookup happens but for some odd reason this isn't automatic for Force
clicks, presumably because some apps want to handle Force clicks
manually (this is why some apps only work for three-finger taps but not
Force clicks for lookups). This isn't documented but I found references
in iTerm/Firefox, and basically we just need to manually handle it and
send off quickLookWithEvent: when handling Force clicks.
For implementing the NSTextInputClient properly, the main issue is
making sure that can work properly with input methods / marked texts,
which is the other primary purpose for this class (other than inputting
keys). For data lookups, I'm representing the grid as a row-major text
(with no newline/space in between) and expose that to the OS. This
already has some issue because it doesn't handle Vim vertical splits
well, as MacVim doesn't really have access to detailed Vim text buffers
easily (unless we do a lot of calls back-and-forth). This means wrapped
texts won't be looked up properly, which I think is ok. Also, the OS
APIs deal with UTF-8 indices, so we can't just convert row/column to raw
indices and have to do a lot of character length calculations
(especially for wide chars like CJK or emojis) to make sure the returned
ranges are consistent and valid. For marked texts though, this presents
a challenge because Vim doesn't really have a strong enough API to
communicate back-and-forth about the marked positions and whatnot (it
only let the GUI know where the current cursor is), and it's hard to
implement APIs like `markedRange` properly because some marked texts
could be hidden or wrapped (if you implement some of these functions
improperly Apple's input methods could start misbehaving especially when
you use arrow keys to navigate). In the end I kept the original
implementation for treating the marked texts as a range starting from 0,
*only* when we have marked text. Kind of a hack but this makes sure we
work both in marked text mode (i.e. when inputting texts) and when doing
lookups. For simplicity I made it so that you can't do data lookups when
in marked text mode now.
Input method:
This change also fixes a quirk in input method as a driveby change.
Previously the logic for calculating the rect for where the candidate
list was quite broken, but now it's calculated correctly using the
desired range and the current cursor position. This matters when say
using Japanese IM and using the left/right arrow to jump to different
sections of the text. If the desired range is in a wrapped line, the new
logic would attempt to pin it to the left-most column of where the
cursor is in the range.
Data detection:
Note that the default implementation is quite bare, and lacks a lot of
smart data detection. For example, if you put your mouse over a URL, it
won't properly select the whole URL, and addresses and dates for example
also won't get grouped together properly. This is because these require
additional implementation (e.g. using NSDataDetector) instead of coming
"for free", and will be handled later. In fact, Apple's WebKit and
NSTextView cheats by calling an internal API framework called "Reveal"
(which you can find out by intercepting NSTextView's calls and/or
looking at WebKit's source code) which is much more powerful and
supports looking up package tracking, airline info, and more, but it's
not available to third-party software (that's why Safari's lookup is so
much better than Chrome/Firefox's).
This isn't tested right now. Future task needs to add XCTest support to
properly test this as there are a lot of edge cases involved here.
Fix#1191
Part of Epic #1311, which contains other items to be implemented.
Problem: Looping over list of lists and changing the list contents works in
Vim9 script, not in a compiled function.
Solution: Mark the loop variable final instead of const. (closes#11347)
Problem: Virtual text "after" wraps to next line even when 'wrap' is off
and 'list' is set.
Solution: Do not use the minimum width when 'wrap' is off. (issue #11336)
Problem: Closure in compiled function gets same variable in block.
Solution: At the end of a block to not always reset the variable count.
(issue #11094)
Problem: Extra empty line between two virtual text "below" when 'wrap' and
'number' are set.
Solution: Reset "before" when there is no text in the screen line.
(closes#11334)
Problem: With 'nowrap' virtual text "after" does not scroll left.
Solution: Skip part of the virtual text that is left of the window.
(closes#11320) Fix going beyond the last column of the window.
Problem: Wrong argument for append() gives two error messages.
Solution: When getting an error for a number argument don't try using it as
a string. (closes#11335)
Problem: With 'nowrap' two virtual text below not displayed correctly.
Solution: Set text_prop_follows before continuing. Correct for number
column. (closes#11333)
Problem: Wrong column when calling setcursorcharpos() with zero lnum.
Solution: Set the line number before calling buf_charidx_to_byteidx().
(closes#11329)
Problem: Quitting/unloading/hiding a terminal buffer does not always work
properly.
Solution: Avoid that ":q!" leaves an empty buffer behind. ":bunload!" also
kills the job and unloads the buffer. ":hide" does not unload the
buffer. (Yee Cheng Chin, closes#11323)
