Problem: 'findfunc' can't return extra info for cmdline completion
(Maxim Kim).
Solution: Handle 'findfunc' return value in cmdline completion like that
of "customlist" functions (zeertzjq).

Problem: Trying to execute code action on an active plugin without
updates leads to nothing. It is more useful if code actions "do
something" on a bigger portion of the confirm buffer.
Solution: Suggest "delete" code action even for active plugins. Trying
to execute it will first show a confirmation buffer with relevant
warning of why this might be not a good idea. Confirming will delete
a plugin.
Problem:
- Empty ranges have different `<`, `<=`, `has` and `intersect` semantics compared to regular ranges.
- `to_inclusive_pos` assumes that the end position of a range is exclusive, which is not true for empty ranges
Solution:
Special case empty ranges in these operations.
Problem:
`builtin_types.lua` seems to be about vimfn (aka "eval", aka
"vimscript", …) specifically, whereas `builtin.lua` is about the Lua
stdlib.
Solution:
Rename it to `vimfn_types.lua`, to align with `vimfn.gen.lua`.
Problem:
Linter missed backtick and double-quote keynames in the quasi-keyset of
the `nvim_create_user_command` docstring.
Solution:
Update the linter to check backtick-surrounded and quote-surrounded key
names.
Problem:
When showing the :connect menu, it is useful to know which servers
are most-recently active. But we don't have a good way to detect that.
Solution:
- Introduce `v:useractive`.
- Include this timestamp in `serverlist({info=true})`.

Problem:
For a given position, it is not easy to compare which of several other positions is closest to it.
Solution:
Add support for converting `vim.Pos` to a buffer byte offset.
This allows for sorting, e.g:
```lua
table.sort(positions, function(pos1, pos2)
return pos1:to_offset() < pos2:to_offset()
end
```
Or a binary search, e.g:
```lua
vim.list.bisect(positions, pos, { key = function(pos) return pos:to_offset() end })
```
Improve the vim.iter annotations with richer generics that track element and
tuple types through iterator pipelines, including multi-value stages and
list-specific methods.
Extend the LuaCATS parser and vimdoc generator so those richer generic classes
and overloads round-trip into the generated help. These annotations are only
supported by EmmyLua, so LuaLS still uses a broader fallback in _meta.lua.

Problem: Entering the pager fails if <ESC> is remapped to :fclose by user.
Solution: Avoid executing mappings with nvim_feedkeys() that closes expanded cmdline.
Problem:
UI tools and orchestration engines need more context than just raw
socket addresses from serverlist(). Without knowing if a server belongs
to the current instance or knowing its PID, UIs cannot display
meaningful options to users.
Solution:
- Added the `info=v:true` option to `serverlist()`.
- When `info` is requested, it implies `peer=true` and returns a list of
dictionaries (defined as `vim.ServerInfo`) with `addr`, `pid` and
`own`.
- Uses an RPC request to `getpid()` across the socket to fetch the
peer's actual process ID.

Problem:
Can't get a command's description from nvim_get_commands when
cmd is string.
Solution:
Returns "desc" field in nvim_get_commands.
`definition` is now empty when cmd is function type.
Problem:
When using `vim.list.unique` or `vim.list.bisect`, if the `key` function is
complex, it can degrade performance, because it is invoked on every comparison
Solution:
The `key` interface convention is designed specifically to address this issue;
performance can be improved by memoizing its results.
Also added the shorthand use of the field name string as the key.
Problem:
Nested workspace capabilities like workspace.fileOperations.didCreate and
workspace.textDocumentContent are not handled consistently for dynamic and
static registration provider lookup.
Solution:
Generate explicit registration-provider mappings from the LSP metadata and use
them when registering and querying capabilities. Add coverage for dynamic and
static nested workspace registrations.
Problem:
`diagnostic.status` only follows the `config.status.format` setting to determine how to display diagnostic signs. However, `signs` can actually also be configured via `config.signs.text`.
Solution:
If the user has set symbols via `config.status.format`, let that determine the content of `signs`; otherwise, use `config.signs.text` for display.
TODO: drop support `type(config.status.format) == 'table'`; users should just configure `config.signs.text` directly.
Problem:
`get_node_text()` returned inconsistent results between buffer and
string sources when a node's range ends at `end_col == 0` (i.e. the node
ends with a newline). The buffer path dropped the trailing newline; the
string path included it correctly.
Solution:
Append `'\n'` in `buf_range_get_text()` when `end_col == 0` and
`start_row ~= end_row`. The `start_row ~= end_row` guard excludes
zero-width nodes at column 0, which should return `""`.
Remove the workaround in the `#trim!` directive that manually
compensated for the missing newline.
Strip whitespace in `resolve_lang()` so injection language nodes ending
at `end_col == 0` (e.g. `">lua\n"`) still resolve correctly.
Problem:
The fallback that tokenizes `eap->arg` by unescaped whitespace (when the
parser doesn't pre-split via `EX_EXPAND` etc.) lives in `nlua_do_ucmd`,
so only user-command callbacks got `eap.fargs`. Builtin commands routed
through `nlua_call_excmd` have to re-parse the args themselves
(e.g. `M.ex_lsp`).
Solution:
- Move the tokenization into `nlua_push_eap` so every Lua handler sees
`eap.fargs`. Keep only the `EX_NOSPC` override in `nlua_do_ucmd` (the
`nargs=1`/`?` case which is genuinely user-command-specific).
- Drop the re-parse in `M.ex_lsp`.
Problem:
LSP clients previously did not handle dynamic registration for off-spec methods
Solution:
Update the client logic to assume support for dynamic registration when
the method is unknown. Adjust the registration provider fallback and
enhance tests to verify correct behaviour for unknown methods and their
registration options. This improves compatibility with servers using
custom dynamic registrations.

Problem:
The argument to `:help` is normalized to fit the general tag format.
I.e. i^U-default, iCTRL-U-default and i_CTRL_U-default should all point
to the i_CTRL_U-default tag. Our normalization adds an underscore around
the CTRL keycode, e.g. iCTRL-GCTRL-J becomes i_CTRL-G_CTRL-J. That's not
necessary if the following part starts with a dash, like the case of
iCTRL-U-default.
Solution:
Do not insert an underscore if the following character is a dash/minus
(-).
docs: update instructions for debugging LSP
Previously, it was suggested to set:
vim.lsp.log.set_format_func(vim.inspect)
This made sense before f72c13341a, when
`format_func` was called once per argument being logged, but since that
commit it's called with the log level followed by the other args, so the
suggested setting would call `vim.inspect(log_level, ....)` which would
just print the human readable name of the current log level and no other
details, for example with this set I saw in my logs:
"DEBUG""DEBUG""DEBUG""DEBUG"
Instead just rely on the default formatter, which will:
> ... log the level, date, source and line number of the
caller, followed by the arguments.
Problem:
After 55ceb31, z= and tselect don't work if `vim.ui.select` is an async
provider (especially terminal buffers).
Solution:
Drop the `vim.wait()` approach, use an async approach.
fix#39506
Problem:
followup to 55ceb314ca#39478
`:oldfiles` and swapfile `:recover` do not delegate to `vim.ui.select`.
Solution:
- Delegate to `vim.ui.select`.
- Fix a long-standing `recover_names` bug where `concat_fnames(dir_name,
files[i], true)` produced malformed `<dir>//<dir>/<file>` paths (also
fixes `swapfilelist()`).
Problem:
- Various `TermRequest` handlers which all do similar things.
- `tty.query` is specific to `XTGETTCAP DCS`, can't be reused for other kinds of terminal queries.
Solution:
Provide `tty.request()`.
Problem: completion: no support for "noinsert" with 'wildmode' and
commandline completion
Solution: Add "noinsert" value to the 'wildmode' option, mirroring
'completeopt' "noinsert" behaviour (glepnir).
fixes: vim/vim#16551closes: vim/vim#20080af494af5ff
Problem:
If a buffer's filetype changes after the LSP client has already
attached (e.g. from json to jsonc via a modeline), but the client
supports both filetypes, it stays attached. It does not notify the
server of the new languageId, causing the server to incorrectly process
the file using the old languageId.
Solution:
Save the languageId used during textDocument/didOpen, and send
textDocument/didClose + textDocument/didOpen when buffer's languageId
changed.
Lsp spec:
0003fb53f1/_specifications/lsp/3.18/textDocument/didOpen.md (L5)
> If the language id of a document changes, the client
> needs to send a textDocument/didClose to the server followed by a
> textDocument/didOpen with the new language id if the server handles
> the new language id as well.
