Release Notes:
- (preview only) vim: Fix panic when scrolling down at end of file
Co-authored-by: Conrad Irwin <conrad.irwin@gmail.com>
This Pull Request introduces various changes to the editor's horizontal
scrolling, mostly focused on vim mode's horizontal scroll motions (`z
l`, `z h`, `z shift-l`, `z shift-h`). In order to make it easier to
review, the logical changes have been split into different sections.
## Cursor Position Update
Changes introduced on https://github.com/zed-industries/zed/pull/32558
added both `z l` and `z h` to vim mode but it only scrolled the editor's
content, without changing the cursor position. This doesn't reflect the
actual behavior of those motions in vim, so these two commits tackled
that, ensuring that the cursor position is updated, only when the cursor
is on the left or right edges of the editor:

## Horizontal Autoscroll Fix
After introducing the cursor position update to both `z l` and `z h` it
was noted that there was a bug with using `z l`, followed by `0` and
then `z l` again, as on the second use `z l` the cursor would not be
updated. This would only happen on the first line in the editor, and it
was concluded that it was because the
`editor:📜:autoscroll::Editor.autoscroll_horizontally` method was
directly updating the scroll manager's anchor offset, instead of using
the `editor:📜:Editor.set_scroll_position_internal` method, like
is being done by the vertical autoscroll
(`editor:📜:autoscroll::Editor.autoscroll_vertically`).
This wouldn't update the scroll manager's anchor, which would still
think it was at `(0, 1)` so the cursor position would not be updated.
The changes in [this
commit](3957f02e18)
updated the horizontal autoscrolling method to also leverage
`set_scroll_position_internal`.
## Visible Column Count & Page Width Scroll Amount
The changes in
d83652c3ae
add a `visible_column_count` field to `editor:📜:ScrollManager`
struct, which allowed the introduction of the `ScrollAmount::PageWidth`
enum.
With these changes, two new actions are introduced,
`vim::normal:📜:HalfPageRight` and
`vim::normal:📜:HalfPageLeft` (in
7f344304d5),
which move the editor half page to the right and half page to the left,
as well as the cursor position, which have also been mapped to `z
shift-l` and `z shift-h`, respectively.
Closes#17219
Release Notes:
- Improved `z l` and `z h` to actually move the cursor position, similar
to vim's behavior
- Added `z shift-l` and `z shift-h` to scroll half of the page width's
to the right or to the left, respectively

Closes #ISSUE
Adds a new `documentation` method to actions, that is extracted from doc
comments when using the `actions!` or derive macros.
Additionally, this PR adds doc comments to as many action definitions in
Zed as possible.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
Release Notes:
- Added initial support for both `z l` and `z h` in vim mode
These changes relate to #17219 but don't yet close the issue, as this
Pull Request is simply adding support for horizontal scrolling in vim
mode and actually moving the cursor to the correct column in the current
row will be handled in a different Pull Request.
Some notes on these changes:
- 2 new default keybindings added to vim's keymap
- `z l` which triggers the new `vim::ColumnRight` action
- `z h` which triggers the new `vim::ColumnLeft` action
- Introduced a new `ScrollAmount` variant, `ScrollAmount::Column(f32)`
to represent horizontal scrolling
- Replaced usage of `em_width` with `em_advance` to actually scroll by
the width of the cursor, instead of the width of the character

Reland of #30345 to fix merge conflicts with the new skip-completions
option
Fixes#29431Fixes#17592
Release Notes:
- vim: Scrolls are no longer added to the jumplist
There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue
Release Notes:
- N/A

Closes#8628
Release Notes:
- Added support for resizing the current pane using vim keybinds with
the intention to follow the functionality of vim
- "ctrl-w +" to make a pane taller
- "ctrl-w -" to make the pane shorter
- "ctrl-w >" to make a pane wider
- "ctrl-w <" to make the pane narrower
- Changed vim pre_count and post_count to globals to allow for other
crates to use the vim count. In this case, it allows for resizing by
more than one unit. For example, "10 ctrl-w -" will decrease the height
of the pane 10 times more than "ctrl-w -"
- This pr does **not** add keybinds for making all panes in an axis
equal size and does **not** add support for resizing docks. This is
mentioned because these could be implied by the original issue

Closes#13579
A major painpoint in the Vim crate has been life-cycle management. We
used to have one global Vim instance that tried to track per-editor
state; this led to a number of subtle issues (e.g. #13579, the mode
indicator being global, and quick toggling between windows letting vim
mode's notion of the active editor get out of sync).
This PR changes the internal structure of the code so that there is now
one `Vim` instance per `Editor` (stored as an `Addon`); and the global
stuff is separated out. This fixes the above problems, and tidies up a
bunch of the mess in the codebase.
Release Notes:
* vim: Fixed accidental visual mode in project search and go to
references
([#13579](https://github.com/zed-industries/zed/issues/13579)).
This makes sure that the `vertical_scroll_margin` doesn't leave the
cursor out of screen or somewhere it shouldn't go when it's higher than
the visible lines on screen.
So we cap it to `visible_line_count / 2`, similar to nvim:
5aa1a9532c/src/nvim/window.c (L6560)Fixes#15101
Release Notes:
- Fixed `ctrl-u`/`ctrl-d` in Vim mode not working correctly when
`vertical_scroll_margin` is set to a really high value.
Co-authored-by: Bennet <bennet@zed.dev>
When setting `"vertical_scroll_margin": 99` or other high values this
can lead to a panic that crashes Zed.
Release Notes:
- vim: Fixed a possible panic that could happen when using a very high
value for `vertical_scroll_margin` that exceeded the number of visible
lines on the screen.

This cleans up the neovim-backed vim tests:
- removed exempted tests (we'll rely on bug reports to find missing edge
cases)
- moved all assertions into non-async fn's so that failures are
reporting on the right file/line
- removed the NeovimBackedBindingTestContext
- renamed a few things to make them clearer
- reduced the number of permutations tested in some cases to reduce
slowest test from 60s to 5s
Release Notes:
- N/A
Part of https://github.com/zed-industries/zed/issues/8081
To avoid confusion and bugs when converting between various row `u32`'s,
use different types for each.
Further PRs should split `Point` into buffer and multi buffer variants
and make the code more readable.
Release Notes:
- N/A

Release Notes:
- vim: Added a setting to control default clipboard behaviour. `{"vim":
{"use_system_clipboard": "never"}}` disables writing to the clipboard.
`"on_yank"` writes to the system clipboard only on yank, and `"always"`
preserves the current behavior. ([#4390
](https://github.com/zed-industries/zed/issues/4390))

After #2641 we noticed that scrolling didn't take a count parameter.
The PageDown/PageUp logic was also broken by an additional -1 (for both
vim mode and not).
