Problem:
Sometimes, when nvim sends the `win_viewport` event, for example when scrolling
with visible folds on the screen, it reports the `scroll_delta` value one batch
into "future". So when the client application is trying to show the new viewport
it's not yet updated, resulting in temporary corruption / screen flickering.
For more details see #23609, and starting from [this comment](
https://github.com/neovide/neovide/pull/1790#issuecomment-1518697747) in
https://github.com/neovide/neovide/pull/1790,, where the issue was first
detected. Note that some of the conclusions in those are not fully accurate, but
the general observations are.
Solution:
When there are pending updates to a Window, delay the `win_viewport` UI event
until the updates are sent. This ensures that there's no flush between sending
the viewport and updating of the lines corresponding to the new viewport.
Document the existing viewport behaviour (for cases where there are no
extra flushes), give a hint about how applications can deal with the slightly
surprising behaviour of the viewport event being sent after the updates.

- docs: mention --luadev-mod to run with lua runtime files
When changing a lua file in the ./runtime folder, a new contributor
might expect changes to be applied to the built Neovim binary.
scroll_delta contains how much the top line of a window moved since the
last time win_viewport was emitted. It is expected to be used to
implement smooth scrolling. For this purpose it only counts "virtual" or
"displayed" so folds should count as one line. Because of this it
adds extra information that cannot be computed from the topline
parameter.
Fixes#19227
The old behaviour (e.g. via `set display-=msgsep`) will not be available.
Assuming that messages always are being drawn on msg_grid
(or not drawn at all, and forwarded to `ext_messages` enabled UI)
will allows some simplifcations and enhancements moving forward.
Ref: 84f5463630
Rename:
- `underlineline` to `underdouble`
- `underdot` to `underdotted`
- `underdash` to `underdashed`
`underdouble` also now takes higher precedence than `undercurl`.
This commit finishes support for colored and styled underlines adding
`CSI 4 : [2,4,5] m` support providing double, dashed, and dotted
underlines
Fixes#17362.
* Add buffer information to tabline_update
Most terminal implementations of the tabline display buffer and tab
information. Many neovim-qt users disable GuiTabline because it lacks
functionality provided in the terminal implementation.
The tabline_update event should include buffer information too, so client GUIs
can display rich useful tabs.
before the behaviour of 'mouse' was inconsistent in external UI,
as some remapping logic would check has_mouse() and others don't
(no difference in TUI or vim classic). With this change, the behaviour
is consistently up to the UI decide (see ui.txt edit)
Behaviour of tui.c is unaffected by this change.
- remove redundant autocmd list
This "grouped" list is useless, it only gets in the way when searching
for event names.
- intro.txt: cleanup
- starting.txt: update, revisit
- doc: `:help bisect`
- mbyte.txt: update aliases 1656367b90. closes#11960
- options: remove 'guifontset'. Why:
- It is complicated and is used by almost no one.
- It is unlikely to be implemented by Nvim GUIs (complicated to parse,
specific to Xorg...).
add proper msg_set_pos event, delet win_scroll_over_*
make compositor click through unfocusable grids
add MsgArea attribute for the message/cmdline area, and add docs and tests
Before now, Nvim always degrades UI capabilities to the lowest-common
denominator. For example, if any connected UI has `ext_messages=false`
then `ext_messages=true` requested by any other connected UI is ignored.
Now `nvim_ui_attach()` supports `override=true`, which flips the
behavior: if any UI requests an `ext_*` UI capability then the
capability is enabled (and the legacy behavior is disabled).
Legacy UIs will be broken while a `override=true` UI is connected, but
it's useful for debugging: you can type into the TUI and observe the UI
events from another connected (UI) client. And the legacy UI will
"recover" after the `override=true` UI disconnects.
Example using pynvim:
>>> n.ui_attach(2048, 2048, rgb=True, override=True, ext_multigrid=True, ext_messages=True, ext_popupmenu=True)
>>> while True: n.next_message();
