Problem: there are new ways to escape textlock or break the cmdwin in
nvim_win_set_config and nvim_tabpage_set_win.
Solution: fix them. Use win_goto to check it in nvim_tabpage_set_win and use the
try_start/end pattern like with similar functions such as nvim_set_current_win
(which uses the existing msg_list, if set).
Careful not to use `wp->handle` when printing the window ID in the error message
for nvim_tabpage_set_win, as win_goto autocommands may have freed the window.
On a related note, I have a feeling some API functions ought to be checking
curbuf_locked...
Problem: nvim_win_set_config does not handle failure in win_split_ins properly
yet, which can cause all sorts of issues. Also nvim_open_win and
nvim_win_set_config do not set the error message to the one from win_split_ins.
Solution: handle failure by undoing winframe_remove, like in win_splitmove.
Make sure autocommands from switching to the altwin fire within a valid window,
and ensure they don't screw things up. Set the error message to that of
win_split_ins, if any.
Also change a few other small things, including:
- adjust win_append to take a tabpage_T * argument, which is more consistent
with win_remove (and also allows us to undo a call to win_remove).
- allow winframe_restore to restore window positions. Useful if `wp` was in a
different tabpage, as a call to win_comp_pos (which only works for the current
tabpage) after winframe_restore should no longer be needed.
Though enter_tabpage calls win_comp_pos anyway, this has the advantage of
ensuring w_winrow/col remains accurate even before entering the tabpage
(useful for stuff like win_screenpos, if used on a window in another tabpage).
(This change should probably also be PR'd to Vim later, even though it doesn't
use winframe_restore for a `wp` in a different tabpage yet).
Problem: saving and restoring all frames to split-move is overkill now
that WinNewPre is not fired when split-moving.
Solution: defer the flattening of frames until win_split_ins begins
reorganising them, and attempt to restore the layout by
undoing our changes. (Sean Dewar)

Adjust winframe_restore to account for Nvim's horizontal separators when the
global statusline is in use. Add a test.
Problem: win_split_ins has no check for E36 when moving an existing
window
Solution: check for room and fix the issues in f_win_splitmove()
(Sean Dewar)

Omit WSP_FORCE_ROOM, as it's not needed for Nvim's autocmd window, which is
floating. Shouldn't be difficult to port later if it's used for anything else.
Make win_splitmove continue working for turning floating windows into splits.
Move the logic for "unfloating" a float to win_split_ins; unlike splits, no
changes to the window layout are needed before calling it, as floats take no
room in the window layout and cannot affect the e_noroom check.
Add missing tp_curwin-fixing logic for turning external windows into splits, and
add a test.
NOTE: there are other issues with the way "tabpage independence" is implemented
for external windows; namely, some things assume that tp_curwin is indeed a
window within that tabpage, and as such, functions like tabpage_winnr and
nvim_tabpage_get_win currently don't always work for external windows (with the
latter aborting!)
Use last_status over frame_add_statusline, as Nvim's last_status already does
this for all windows in the current tabpage. Adjust restore_full_snapshot_rec to
handle this.
This "restore everything" approach is changed in a future commit anyway, so only
ensure it's robust enough to just pass tests.
Keep check_split_disallowed's current doc comment, as it's actually a bit more
accurate here. (I should probably PR Vim to use this one)
Allow f_win_splitmove to move a floating "wp" into a split; Nvim supports this.
Continue to disallow it from moving the autocommand window into a split (funnily
enough, the check wasn't reachable before, as moving a float was disallowed),
but now return -1 in that case (win_splitmove also returns FAIL for this, but
handling it in f_win_splitmove avoids us needing to switch windows first).
Cherry-pick Test_window_split_no_room fix from v9.1.0121.
Update nvim_win_set_config to handle win_split_ins failure in later commits.
Problem: nvim_open_win blocking all win_set_buf autocommands when !enter &&
!noautocmd is too aggressive.
Solution: temporarily block WinEnter/Leave and BufEnter/Leave events when
setting the buffer. Delegate the firing of BufWinEnter back to win_set_buf,
which also has the advantage of keeping the timing consistent (e.g: before the
epilogue in enter_buffer, which also handles restoring the cursor position if
autocommands didn't change it, among other things). Reword the documentation for
noautocmd a bit.
I pondered modifying do_buffer and callees to allow for BufEnter/Leave being
conditionally disabled, but it seems too invasive (and potentially error-prone,
especially if new code paths to BufEnter/Leave are added in the future).
Unfortunately, doing this has the drawback of blocking ALL such events for the
duration, which also means blocking unrelated such events; like if window
switching occurs in a ++nested autocmd fired by win_set_buf. If this turns out
to be a problem in practice, a different solution specialized for nvim_open_win
could be considered. :-)
Problem: currently, for splits, nvim_win_set_config accepts win without any of
split or vertical set, which has little effect and seems error-prone.
Solution: require at least one of split or vertical to also be set for splits.
Also, update nvim_win_set_config docs, as it's no longer limited to just
floating and external windows.
Problem: splitting is disallowed in some cases to prevent the window layout
changes while a window is closing, but it's not checked for.
Solution: check for this, and set the API error message directly.
(Also sneak in a change to tui.c that got lost from #27352; it's a char* buf,
and the memset is assuming one byte each anyway)
Problem: WinNew and win_enter autocommands can delete the target buffer to
switch to, causing a heap-use-after-free.
Solution: store a bufref to the buffer, check it before attempting to switch.
Problem: if switch_win{_noblock} fails to restore the old curwin after WinNew
(e.g: it was closed), wp will become the new curwin, but win_set_buf enter
events would still be blocked if !enter && !noautocmd.
Solution: fire them, as we've actually entered the new window.
Note: there's a problem of switch_win{_noblock} failing to restore the old
curwin, leaving us in wp without triggering WinEnter/WinLeave, but this affects
all callers of switch_win{_noblock} anyways. (It's also not clear how WinLeave
can be called if the old curwin was closed already).
Problem: BufWinEnter is not fired when not entering a new window, even when a
different buffer is specified and buffer-related autocommands are unblocked
(!noautocmd).
Solution: fire it in the context of the new window and buffer. Do not do it if
the buffer is unchanged, like :{s}buffer.
Be wary of autocommands! For example, it's possible for nvim_win_set_config to
be used in an autocommand to move a window to a different tabpage (in contrast,
things like wincmd T actually create a *new* window, so it may not have been
possible before, meaning other parts of Nvim could assume windows can't do
this... I'd be especially cautious of logic that restores curwin and curtab
without checking if curwin is still valid in curtab, if any such logic exists).
Also, bail early from win_set_buf if setting the temp curwin fails; this
shouldn't be possible, as the callers check that wp is valid, but in case that's
not true, win_set_buf will no longer continue setting a buffer for the wrong
window.
Note that pum_create_float_preview also uses win_set_buf, but from a glance,
doesn't look like it properly checks for autocmds screwing things up (win_enter,
nvim_create_buf...). I haven't addressed that here.
Also adds some test coverage for nvim_open_win autocommands.
Closes#27121.
Problem: win_set_config should have the observable effect of moving an existing
window to another place, but instead fires autocommands as if a new window was
created and entered (and does not fire autocommands reflecting a "return" to the
original window).
Solution: do not fire win_enter-related autocommands when splitting the window,
but continue to fire them when entering the window that fills the new space when
moving a window to a different tabpage, as the new curwin changes.
Also, remove "++once" from the WinEnter autocmd in the other test, as omitting
it also crashed Nvim before this fix.
Problem: win_enter autocommands can close new_curwin, crashing if it was the
last window in its tabpage after removing win, or can close parent, crashing
when attempting to split it later.
Solution: remove win first, check that parent is valid after win_enter.
NOTE: This isn't actually quite right, as this means win is not in the window
list or even has a frame when triggering enter autocommands (so it's not
considered valid in the tabpage). This is addressed in later commits.
Problem: 'shortmess' "F" flag doesn't work properly with 'autoread'
(after 9.1.0154)
Solution: Hide the file info message instead of the warning dialog
(zeertzjq)

Problem: Text is not redrawn with 'relativenumber' when only the 'statuscolumn' is redrawn after inserted lines.
Solution: Force a full redraw if statuscolumn width changed.
Problem:
`vim.lsp.util.rename()` deletes the buffers that are affected by
renaming. This has undesireable side effects. For example, when renaming
a directory, all buffers under that directory are deleted and windows
displaying those buffers are closed. Also, buffer options may change
after renaming.
Solution:
Rename the buffers with :saveas.
An alternative approach is to record all the relevant states and restore
it after renaming, but that seems to be more complex. In fact, the older
version was attempting to restore the states but only partially and
incorrectly.
- Added `@inlinedoc` so single use Lua types can be inlined into the
functions docs. E.g.
```lua
--- @class myopts
--- @inlinedoc
---
--- Documentation for some field
--- @field somefield integer
--- @param opts myOpts
function foo(opts)
end
```
Will be rendered as
```
foo(opts)
Parameters:
- {opts} (table) Object with the fields:
- somefield (integer) Documentation
for some field
```
- Marked many classes with with `@nodoc` or `(private)`.
We can eventually introduce these when we want to.
Problem:
vim._watch.watchdirs has terrible performance.
Solution:
- On linux use fswatch as a watcher backend if available.
- Add File watcher section to health:vim.lsp. Warn if watchfunc is
libuv-poll.
Problem: Floats are arbitrarily positioned at 1 row above screen size.
Solution: Position at 1 row above 'cmdheight', only if window is hidden behind the message area.
Previously rename would unconditionally read the to-be-renamed file from the
disk and write it to the disk. This is redundant in some cases
If the file is not already loaded, it's not attached to lsp client, so nvim
doesn't need to care about this file.
If the file is loaded but has no change, it doesn't need to be written.
Problem: Some LSP servers return `textDocument/documentLink` responses
containing file URIs with line/column numbers in the fragment.
`vim.uri_to_fname` returns invalid file names for these URIs.
Solution: Remove the URI fragment from file URIs.
Problem:
The documentation flow (`gen_vimdoc.py`) has several issues:
- it's not very versatile
- depends on doxygen
- doesn't work well with Lua code as it requires an awkward filter script to convert it into pseudo-C.
- The intermediate XML files and filters makes it too much like a rube goldberg machine.
Solution:
Re-implement the flow using Lua, LPEG and treesitter.
- `gen_vimdoc.py` is now replaced with `gen_vimdoc.lua` and replicates a portion of the logic.
- `lua2dox.lua` is gone!
- No more XML files.
- Doxygen is now longer used and instead we now use:
- LPEG for comment parsing (see `scripts/luacats_grammar.lua` and `scripts/cdoc_grammar.lua`).
- LPEG for C parsing (see `scripts/cdoc_parser.lua`)
- Lua patterns for Lua parsing (see `scripts/luacats_parser.lua`).
- Treesitter for Markdown parsing (see `scripts/text_utils.lua`).
- The generated `runtime/doc/*.mpack` files have been removed.
- `scripts/gen_eval_files.lua` now instead uses `scripts/cdoc_parser.lua` directly.
- Text wrapping is implemented in `scripts/text_utils.lua` and appears to produce more consistent results (the main contributer to the diff of this change).
With "intermediate" flag, only using minimal timeout is too short and
may lead to failures.
Also remove the fallback timeout in screen:expect_unchanged(), as having
a different fallback timeout than screen:expect() is confusing.
Currently, highlight.on_yank() does buffer-local highlighting, this PR
makes it window scoped.
Also fix the problem that when yanking in a buffer, moving to another
buffer, and yanking before the original buffer highlight disappears, the
original buffer highlight won't disappear on timeout.
