Problem:
Default statusline doesn't show progress status.
Solution:
- Provide `vim.ui.progress_status()`.
- Include it in the default 'statusline'.
How it works:
Status text summarizes "running" progress messages.
- If none: returns empty string
- If one running item: "title: percent%"
- If multiple running items: "Progress: N items avg-percent%"
Problem:
Checking the extension of a file is done often, e.g. in Nvim's codebase
for differentiating Lua and Vimscript files in the runtime. The current
way to do this in Lua is (1) a Lua pattern match, which has pitfalls
such as not considering filenames starting with a dot, or (2)
fnamemodify() which is both hard to discover and hard to use / read if
not very familiar with the possible modifiers.
vim.fs.ext() returns the file extension including the leading dot of
the extension. Similar to the "file extension" implementation of many
other stdlibs (including fnamemodify(file, ":e")), a leading dot
doesn't indicate the start of the extension. E.g.: the .git folder in a
repository doesn't have the extension .git, but it simply has no
extension, similar to a folder named git or any other filename without
dot(s).
Introduce _provider_foreach to iterate over all matching provider
capabilities for a given LSP method, handling both static and dynamic
registrations. Update diagnostic logic and tests to use the new
iteration approach, simplifying capability access and improving
consistency across features.
Problem
Unlike inlay hints, code lenses are closely related to running commands;
a significant number of code lenses are used to execute a command (such
as running tests). Therefore, it is necessary to provide a default
mapping for them.
Solution
Add a new default mapping "grx" (mnemonic: "eXecute", like "gx").
Problem:
Mouse popup menus (right-click context menus) do not respect the
'pumborder' option and could overflow screen boundaries when borders
were enabled near the edge.
Solution:
- Remove the mouse menu exclusion from border rendering.
- Add boundary check to shift menu left when border would exceed screen
width, ensuring complete visibility of menu content and borders.
Problem: Entering the pager is scheduled to avoid errors while in the
cmdwin. Meanwhile the current window is used as a condition to
detect an active pager.
Solution: Keep track of when the user is in the pager (or entered the
cmdwin while the pager was open).
Problem:
No way to iterate configs. Users need to reach
for `vim.lsp.config._configs`, an internal interface.
Solution:
Provide vim.lsp.get_configs().
Also indirectly improves :lsp enable/disable completion
by discarding invalid configs from completion.
Problem:
If buffer update callbacks poll for uv events during terminal scrollback
refresh, new output from PTY process may lead to incorrect scrollback.
Solution:
Don't poll for output to the same terminal as the one being refreshed.
Problem:
`nvim_echo(…, {id=…})` accepts user-defined id as a string or integer.
Generated ids are always higher than last highest msg-id used. Thus
plugins may accidentally advance the integer id "address space", which,
at minimum, could lead to confusion when troubleshooting, or in the
worst case, could overflow or "exhaust" the id address space.
There's no use-case for it, and it could be the mildly confusing, so we
should just disallow it.
Solution:
Disallow *integer* user-defined message-id.
Only allow *string* user-defined message-id.
Problem:
nvim_get_option_value with "filetype" set silently returns incorrect
defaults if autocommands are blocked, like when they're already running.
Solution:
Allow its FileType autocommands to nest: `do_filetype_autocmd(force=true)`.
Also error if executing them fails, rather than silently return wrong defaults.
Endless nesting from misbehaving scripts should be prevented by the recursion
limit in apply_autocmds_group, which is 10.
Problem:
On windows, if a drive-relative path doesn't contain a slash,
`path_to_absolute` can't split out the relative component, causing
expansion to fails. e.g., `c:` `c:.` `c:..` `c:foo.md`
Solution:
For these cases, we can pass letter and colon to `path_full_dir_name`.
Notably, `..` is included as well.
if that relative path exists, it can be expanded correctly.
Problem:
When `to_vim_value[info.metatype](info, value)` is called, a list value
such as `{'eob:a'}` is treated like a map, which generates `1:eob:a`.
Note: commands like `:lua vim.opt.wildmode={'longest:full'}` are not an
issue because only cases harcoded in `key_value_options` have metatype `map`.
Solution:
Check for array type and use the same logic as in array metatypes.
Problem:
Right-click menu fails with E335 when using V in Insert mode (after
i_ctrl-o). The mode detection checks restart_edit before VIsual_active,
incorrectly selecting Insert mode binding even when Visual mode is
active.
Solution:
Check Visual mode before Insert mode, to match get_menu_mode() priority
order.
Problem:
When code lens is enabled, `on_attach` is executed, but it does not trigger a redraw. Another event, eg, moving the cursor, is required to trigger a redraw and execute the decoration provider's `on_win`.
Solution:
Trigger a `redraw` after each request is completed.
Problem:
"[Process exited]" is implemented in C with anonymous namespace
and users have no way to hide it.
Solution:
- Handle "TermClose" event in Lua.
- User can delete the "nvim.terminal" augroup to avoid "[Process exited]".
Problem:
Applications running inside :terminal that use DEC private mode 2026
(synchronized output) to batch screen updates get garbled rendering.
Neovim's embedded libvterm does not handle mode 2026, so the
synchronization sequences are ignored and intermediate screen states
leak through as visual corruption.
Solution:
Add mode 2026 support to libvterm's state machine and wire it through
to terminal.c. When an application enables mode 2026, invalidation of
the terminal buffer is deferred until the application disables it,
causing all accumulated screen updates to flush as a single
atomic refresh.
* fix(terminal): harden sync output redraw gating
Problem:
The initial mode 2026 implementation gated invalidate_terminal()
but missed three other redraw paths: term_sb_push/term_sb_pop
bypassed the gate by directly adding to invalidated_terminals,
refresh_timer_cb could fire mid-sync flushing partial state, and
the 10ms timer delay after sync-end left a window for stale
repaints.
Solution:
- Gate term_sb_push/term_sb_pop during synchronized output
- Skip syncing terminals in refresh_timer_cb
- On sync end, schedule a zero-delay full-screen refresh via
sync_flush_pending flag in terminal_receive()
- Add news.txt entry for mode 2026 support

* test(terminal): add vterm unit tests for mode 2026
Add unit-level tests for synchronized output (mode 2026) to
vterm_spec.lua, covering settermprop callbacks and DECRQM
query/response.

* fix(terminal): address review feedback for mode 2026
- Use multiqueue_put(main_loop.events) instead of restarting the
global refresh timer on sync end, to avoid affecting other
invalidated terminals.
- Add screen:expect_unchanged() to verify screen doesn't update
during sync mode.
- Merge buffer-lines test into existing test.

Problem:
Completion preview always assumes plain text, ignoring LSP documentation "kind".
Solution:
Pass markup kind from completion item to info window, or fallback to PlainText.
Problem: 'jumpoptions' "view" doesn't remember skipcol and may lead to
glitched display with 'smoothscroll'.
Solution: Save skipcol in the mark view. Also make sure skipcol doesn't
exceed line size.
vim-patch:9.2.0174: diff: inline word-diffs can be fragmented
Problem: When using 'diffopt=inline:word', lines were excessively
fragmented with punctuation creating separate highlight
blocks, making it harder to read the diffs.
Solution: Added 'diff_refine_inline_word_highlight()' to merge
adjacent diff blocks that are separated by small gaps of
non-word characters (up to 5 bytes by default) (HarshK97).
When using inline:word diff mode, adjacent changed words separated by
punctuation or whitespace are now merged into a single highlight block
if the gap between them contains fewer than 5 non-word characters.
This creates more readable diffs and closely matches GitHub's own diff
display.

Problem:
No way to disable progress messages in cmdline message area. If
a third-party plugin handles Progress events + messages, the user may
not want the "redundant" progress displayed in the cmdline message area.
Solution:
Support "progress:c" entry in 'messageopts' option.
Problem:
The `float` field of vim.diagnostic.config can be a function,
but diagnostic.open_float() does not handle it correctly.
Solution:
Add handling for it in open_float().
Problem: nvim_open_tabpage's "enter" argument is optional, which is inconsistent
with nvim_open_win.
Solution: make it a (non-optional) positional argument, like nvim_open_win.
Also change "enter"'s description to be more like nvim_open_win's doc.
Problem: "after" in nvim_open_tabpage is inconsistent with how a count works
with :tab, :tabnew, etc. Plus, the name "after" implies it's inserted after that
number.
Solution: internally offset by 1. Allow negative numbers to mean after current.
Hmm, should we even reserve sentinels for after current? Callers can probably
just use nil...
- Cleanup, remove redundant comments, add more tests.
- Enhance win_new_tabpage rather than create a new function for !enter, and use
a different approach that minimizes side-effects. Return the tabpage_T * and
first win_T * it allocated.
- Disallow during textlock, like other APIs that open windows.
- Remove existing win_alloc_firstwin error handling from win_new_tabpage; it's
not needed, and looks incorrect. (enter_tabpage is called for curtab, which is
not the old tabpage! Plus newtp is not freed)
- Fix checks after creating the tabpage:
- Don't fail if buf wasn't set successfully; the tab page may still be valid
regardless. Set buffer like nvim_open_win, possibly blocking Enter/Leave
events. (except BufWinEnter)
- tp_curwin may not be the initial window opened by win_new_tabpage. Use the
win_T * it returns instead, which is the real first window it allocated,
regardless of autocmd shenanigans.
- Properly check whether tab page was freed; it may have also been freed
before win_set_buf. Plus, it may not be safe to read its handle!
Problem:
"Sorry" in a message (1) is noise, and (2) actually reduces the clarity
of the message because the titlecasing of "Sorry" distracts from the
actually important part of the message.
Solution:
Drop "Sorry" from messages.
Problem: #38316 is a bit aggressive; we need not always leave Terminal mode if
autocmds put us in a different terminal.
Solution: don't skip entering; let terminal_check_focus handle whether we should
immediately leave.
Problem:
`K` in help files may fail in some noisy text. Example:
(`fun(config: vim.lsp.ClientConfig): boolean`)
^cursor
Solution:
- `:help!` (bang, no args) activates DWIM behavior: tries `<cWORD>`,
then trims punctuation until a valid tag is found.
- Set `keywordprg=:help!` by default.
- Does not affect `CTRL-]`, that is still fully "tags" based.
Problem: heap-use-after-free possible when entering Terminal mode if
autocommands close the terminal.
Solution: set the refcount. Skip to the end if we must close the terminal.
Problem: "win" is allowed in external window configs in some cases. External
window converted to normal float can't move tabpages in one nvim_win_set_config
call. External window can't be turned into a normal split.
Solution: disallow setting "win" for external windows. Allow external window to
move tabpages, which turns it non-external. Allow external window to be turned
into a (non-external) split.
parse_win_config has more validation issues from not considering the window's
existing config enough (not from this PR). For example, zindex can be set for an
existing split if "split"/"vertical" isn't given, despite intending for that to
be an error. Plus the logic is confusing.
It could do with a refactor at some point...
Problem: more cases where it may not be safe to move a window between tabpages.
Solution: check them.
Rather speculative... I haven't spend much time looking, but I didn't find
existing code that sets these locks to skip checking win_valid. (what I did find
called it anyway, like in win_close) Still, I think it's a good precaution for
what future code might do.
If the fact that nvim_win_set_config *actually* moves windows between tabpages
causes unforeseen issues, "faking" it like ":wincmd T" may be an alternative:
split a new window, close the old one, but instead also block autocmds, copy the
old window's config, and give it its handle?
Problem: converting a split to a floatwin may not remove the last statusline
when needed. (e.g: 'ls' is 1)
Solution: call last_status/win_comp_pos in win_new_float, after win_remove.
Also fix float_pos formatting for screen snapshots so it doesn't give a nil
error for external windows.
Not an issue from this PR.
Problem: only possible to move floats between tabpages if relative=win, which
has the restrictive effect of also anchoring it to the target window.
Solution: allow "win" without "relative" or "split"/"vertical". Only assume
missing "win" is 0 if relative=win is given to maintain that behaviour. (or when
configuring a new window)
Also add an error when attempting to change a split into a float that's in
another tabpage, as this isn't actually supported yet. (until the next commit)
Maybe this could do with some bikeshedding. Unclear if "win" should require
"relative" to be given, like with "row"/"col"; this can be annoying though as
specifying "relative" requires other fields to be given too.
Problem: possible to configure a split as a floatwin with relative=win that is
relative to itself.
Solution: fix the check.
Not caused by this PR; just something I noticed when about to fix the validation
logic.
Problem: when nvim_win_set_config moves a floatwin between tabpages, its grid
may remain if temporarily inside another tabpage. Also, things like tablines
aren't redrawn.
Solution: always remove its grid. Set must_redraw so things are redrawn even if
w_redr_type was already set for the old tabpage.
I don't think it's necessary to do anything extra here when removing the grid:
- win_ui_flush calls ui_call_win_hide anyway, and calling it manually ends up
sending two win_hide events.
- ui_comp_remove_grid safely does nothing if the grid doesn't exist.
- w_pos_changed is set by win_config_float later, if that's needed. I think the
pending_comp_index_update set by ui_comp_remove_grid is enough anyway, at
least for making sure win_ui_flush sends win_hide.
Added test fails with the prior approach of checking `parent_tp != curtab`, but
also `win_tp == curtab`. (which is a better, but still flawed alternative)
The added redrawing here also supersedes setting w_hl_needs_update, and also
redraws stuff like the tabline to pass the new test.
- Factor out logic to keep nvim_win_set_config clean.
- Clean up a few things, remove redundant logic, reflow some lines.
- Add some more comments where appropriate.
- Don't consider negative "win", as that's only relevant for splits.
- Add more test coverage.
- Add news.txt entry.
