Problem:
Using a single RPC request to child server isn't enough to prevent race
between nvim_paste and nvim_input.
Solution:
Ensure both child client and child server have processed pending events
by sending an empty DCS response to the child client and waiting for
TermResponse autocommand on the child server.
Problem: on `CompleteDone` cursor can jump to the end of line instead of
the end of the completed word.
Solution: remove only inserted word for snippet expansion instead of everything
until eol.

Problem: Currently completion attribute hl_group is combined with
all items, which is redundant and confusing with kind_hlgroup
Solution: Renamed to abbr_hlgroup and combine it only with the abbr item
(glepnir).

Problem:
- Some servers like LuaLS add unwanted blank lines after multiline
`@param` description.
- List items do not wrap nicely.
Solution:
- When rendering the LSP doc hover, remove blank lines in each `@param`
or `@return`.
- But ensure exactly one empty line before each.
- Set 'breakindent'.
Problem: Lua accessors for
- global, local, and special variables (`vim.{g,t,w,b,v}.*`), and
- options (`vim.{o,bo,wo,opt,opt_local,opt_global}.*`),
do not have command-line completion, unlike their vimscript counterparts
(e.g., `g:`, `b:`, `:set`, `:setlocal`, `:call <fn>`, etc.).
Completion for vimscript functions (`vim.fn.*`) is incomplete and does
not list all the available functions.
Solution: Implement completion for vimscript function, variable and
option accessors in `vim._expand_pat` through:
- `getcompletion()` for variable and vimscript function accessors, and
- `nvim_get_all_options_info()` for option accessors.
Note/Remark:
- Short names for options are yet to be implemented.
- Completions for accessors with handles (e.g. `vim.b[0]`, `vim.wo[0]`)
are also yet to be implemented, and are left as future work, which
involves some refactoring of options.
- For performance reasons, we may want to introduce caching for
completing options, but this is not considered at this time since the
number of the available options is not very big (only ~350) and Lua
completion for option accessors appears to be pretty fast.
- Can we have a more "general" framework for customizing completions?
In the future, we may want to improve the implementation by moving the
core logic for generating completion candidates to each accessor (or
its metatable) or through some central interface, rather than writing
all the accessor-specific completion implementations in a single
function: `vim._expand_pat`.
An implication of this current approach is that `NVIM_API_LEVEL` should be
bumped when a new Lua function is added.
TODO(future): add a lint check which requires `@since` on all new functions.
ref #25416
Some composite/compound types even as basic as `(string|number)[]` are
not currently supported by the luacats LPEG grammar used by gen_vimdoc.
It would be parsed & rendered as just `string|number`.
Changeset adds better support for these types.
Ensure the screen is fully updated before blocking for input. This did
not always happen before, for example when setting `cursorline
scrolloff=9999`, which lead to jerky movement when using some GUI
applications.
Because of the duality of redraw_later, this can't be done in
command-line or when waiting for "Press ENTER". In many of those cases
the redraw is expected AFTER the key press, while normally it should
update the screen immediately. So, those special cases are excluded.
Problem: fixed order of items in insert-mode completion menu
Solution: Introduce the 'completeitemalign' option with default
value "abbr,kind,menu" (glepnir).
Adding an new option `completeitemalign` abbr is `cia` to custom
the complete-item order in popupmenu.

Problem:
The `_watch.watch()` strategy may fail if the given path does not exist:
…/vim/_watch.lua:101: ENOENT: no such file or directory
stack traceback:
[C]: in function 'assert'
…/vim/_watch.lua:101: in function <…/vim/_watch.lua:61>
[string "<nvim>"]:5: in main chunk
- `_watch.watch()` actively asserts any error returned by `handle:start()`.
- whereas `_watch.watchdirs()` just ignores the result of `root_handle:start()`.
Servers may send "client/registerCapability" with "workspace/didChangeWatchedFiles"
item(s) (`baseUri`) which do not actually exist on the filesystem:
https://github.com/neovim/neovim/issues/28058#issuecomment-2189929424
{
method = "client/registerCapability",
params = {
registrations = { {
method = "workspace/didChangeWatchedFiles",
registerOptions = {
watchers = { {
globPattern = {
baseUri = "file:///Users/does/not/exist",
pattern = "**/*.{ts,js,mts,mjs,cjs,cts,json,svelte}"
}
},
...
}
Solution:
- Remove the assert in `_watch.watch()`.
- Show a once-only message for both cases.
- More detailed logging is blocked until we have `nvim_log` / `vim.log`.

Problem:
Linematch used to use strchr to navigate a string, however strchr does
not supoprt embedded NULs.
Solution:
Use `mmfile_t` instead of `char *` in linematch and introduce `strnchr()`.
Also remove heap allocations from `matching_char_iwhite()`
Fixes: #30505
Problem: No clear way to check whether parsers are available for a given
language.
Solution: Make `language.add()` return `true` if a parser was
successfully added and `nil` otherwise. Use explicit `assert` instead of
relying on thrown errors.
Problem:
Headings in :help do not stand out visually.
Solution:
Define a non-standard `@markup.heading.1.delimiter` group and
special-case it in `highlight_group.c`.
FUTURE:
This is a cheap workaround until we have #25718 which will enable:
- fully driven by `vimdoc/highlights.scm` instead of using highlight
tricks (`guibg=bg guifg=bg guisp=fg`)
- better support of "cterm" ('notermguicolors')
Problem: diff mode does not handle overlapping diffs correctly
Solution: correct the logic to handle overlapping blocks

Vim merges overlapped diff blocks and it doesn't work expectedly

Problem:
checkhealth report sections are not visually separated.
Solution:
Highlight with "reverse".
TODO: migrate checkhealth filetype to use treesitter.
TODO: default :help should also highlight headings more boldy!
**Problem:** `is_ancestor()` uses a slow, bottom-up parent lookup which
has performance pitfalls detailed in #28512.
**Solution:** Take `is_ancestor()` from $O(n^2)$ to $O(n)$ by
incorporating the use of the `child_containing_descendant()` function
Problem: When using nvim_paste in a mapping during a macro recording,
both the mapping and the paste are recorded, causing the paste
to be performed twice when replaying the macro.
Solution: Only record a paste when it is from RPC.
Unfortunately this means there is no way for a script to make a recorded
paste. A way to enable that can be discussed later if there is need.
Before this PR, the behavior of nvim_paste is:
- When vim.paste() returns false, return false to the client, but treat
following chunks normally (i.e. rely on the client cancelling the
paste as expected).
- When vim.paste() throws an error, still return true to the client, but
drain the following chunks in the stream without calling vim.paste().
There are two problems with such behavior:
- When vim.paste() errors, the client is still supposed to send the
remaining chunks of the stream, even though they do nothing.
- Having different code paths for two uncommon but similar situations
complicates maintenance.
This PR makes both the cancel case and the error case return false to
the client and drain the remaining chunks of the stream, which, apart
from sharing the same code path, is beneficial whether the client checks
the return value of nvim_paste or not:
- If the client checks the return value, it can avoid sending the
following chunks needlessly after an error.
- If the client doesn't check the return value, chunks following a
cancelled chunk won't be pasted on the server regardless, which leads
to less confusing behavior.
In the api_info() output:
:new|put =map(filter(api_info().functions, '!has_key(v:val,''deprecated_since'')'), 'v:val')
...
{'return_type': 'ArrayOf(Integer, 2)', 'name': 'nvim_win_get_position', 'method': v:true, 'parameters': [['Window', 'window']], 'since': 1}
The `ArrayOf(Integer, 2)` return type didn't break clients when we added
it, which is evidence that clients don't use the `return_type` field,
thus renaming Dictionary => Dict in api_info() is not a breaking change.

Problem: When input immediately follows end of bracketed paste, the
nvim_input may be processed before the nvim_paste.
Solution: Ensure some waiting after the end of a bracketed paste.
Problem: incorrect internal diff with an empty file
Solution: Set pointer to NULL, instead of using an empty line file
(Yukihiro Nakadaira)
When using internal diff, empty file is read as one empty line file.
So result differs from external diff.

Problem:
The default builtin UI client does not declare its client info. This
reduces discoverability and makes it difficult for plugins to identify
the UI.
Solution:
- Call nvim_set_client_info after attaching, as recommended by `:help dev-ui`.
- Also set the "pid" field.
- Also change `ui_active()` to return a count. Not directly relevant to
this commit, but will be useful later.
This module is generally used by any tests that need the full Nvim TUI
instead of `screen.lua`. Thus it should live in `functional/` instead of
in `functional/terminal/`.
