Problem:
Too much boilerplate needed to use Lua to impl an excmd or f_xx
function.
Solution:
- Add `nlua_call_vimfn` which takes the args typval, executes
Lua, and returns a typval.
- refactor(excmd): lua impl for :log, :lsp
Problem: Calling `vim.filetype.match({ filename = '...', buf = ... })`
during startup results in an error due to not yet defined
`g:ft_ignore_pat`.
Solution: Add a guard to check `g:ft_ignore_pat` related properties only
if the variable is defined. This also allows to simplify other tests
which did not depend on `g:ft_ignore_pat` but required it explicitly
set to work.
* fix(api): allow silencing "Too many highlight groups" error
Problem: Using Lua's `vim.api.nvim_set_hl(0, 'New', {...})` can fail if
there are too many existing highlight groups. However, this error can
not be silenced with `pcall`.
Solution: Make it possible to silence in `nvim_set_hl` and
`nvim_get_hl_id_by_name`.
* fix(lsp): limit number of groups created by `document_color()`
Problem: A file can contain many string colors that would be highlighted
by an LSP server. If this number crosses 19999 (maximum number of
allowed highlight groups), there are general issues with creating
other highlight groups, which can break functionality outside of
`vim.lsp.document_color`.
Solution: Limit number of highlight groups that are created by
`vim.lsp.document_color` to 10000 (half of allowed maximum).
This is not a 100% solution (since there can exist more than 10000
other highlight groups), but explicitly checking number of groups is
slow and 10000 should (hopefully) be enough for most use cases.

Problem:
- Builtin "Vimscript" functions (f_xx) are mostly implemented in C.
Partly that's because there is some boilerplate required to call out
to Lua.
- Calls to `vim.fn.foo()` always marshall over the Lua <=> Vimscript
("typval") bridge, even if `fn.foo()` is implemented entirely in Lua:
```
Lua => typval => Object => Lua => Object => typval => Lua.
```
Solution:
Functions declared in eval.lua with `func_lua` are implemented in
entirely in Lua (`_core/vimfn.lua`).
- `gen_eval.lua` wires `func_lua` entries to `lua_wrapper`, which handles
the typval conversion for Vimscript callers (slow path).
- `nlua_call()` detects `func_lua` functions and calls the Lua
implementation directly. This eliminates all conversion overhead for
Lua callers (fast path).
- Validate at build-time that `func`, `func_float`, and `func_lua` are
mutually exclusive.
- Migrate `hostname()` as a toy example, to show the idea.
Problem: Documentation based on patches is outdated.
Solution: Add changes to documentation in a patch.
853886722c
Trailing space was removed in later patches.
Also fix a few more misplaced error numbers from #8155.

Problem: - Paging keys in the dialog window consume input when the user
may not expect it. The dismissable title hint intended to
mitigate that results in having to press Escape twice to
abandon the prompt.
- Mimicked "msgsep" float border is taking up unnecessary
space when window takes up the entire screen.
Solution: - Use (conventional, albeit less convenient) keys intended
for scrolling to page the dialog window:
<(Mousewheel/Page)Up/Down>, <Home/End>.
- Only set the float top border when separation is actually
necessary, i.e. window does not reach the first row.
Problem:
Difficult for us to provide default handlers for functions like
`vim.lsp.buf.definition`. When users wanted to fine-tune the default behavior,
they don't know how.
Solution:
- Document an example providing `on_list` boilerplate to make it easier for
users to modify and override.
- Also, considering that the parameters of the previous
`on_list`(`vim.lsp.ListOpts.OnList`) are compatible with the parameters of
`setqflist`, remove that custom type in favor of passing
`vim.fn.setqflist.what`.
Problem:
`TSNode:id()` returns the underlying c pointer as a string, which may include
NUL bytes. In PUC Lua, `('%s'):format('\0a\0')` returns `''` and not `'\0a\0'`
(i.e. treats the string as a c-string (which terminates at the NUL byte)).
This resulted in two different nodes being able to have the same id.
Solution:
Use concatenation `..` instead of `string.format()`.
Problem:
- Choosing a new EXX error code is tedious.
- It's possible to accidentally use an EXX error code for different
purposes.
Solution:
Add a lint check which requires EXX error codes to have a :help tag.
This also avoids duplicates because `make doc` does `:helptags ++t doc`
which fails if duplicates are found.
Problem: Sometimes automatic lockfile synchronization after `:restart`
might fail, like due to bad/absent Internet connection. This would
remove failed to install entries from the lockfile (since they are not
on disk and lockfile is meant to lock the latest plugin version on
disk).
Solution: Document that this should be treated as an unwanted update and
use steps similar to "Revert plugin after an update" use case.
Problem: Using severity names (like "ERROR", "WARN") in functions like
`vim.diganostic.get()` and `vim.diagnostic.config()` is allowed and
tested for many years now. But documentation about it can be clearer.
Solution: Explicitly mention that severity names are allowed in some
situations. Ideally, it would also require updating typing for
`vim.diagnostic.SeverityFilter`, but that looks problematic to do
robustly.
Problem:
Naming conventions are not automatically checked.
Solution:
Add a check to the doc generator. Eventually we should extract this
somehow, but that will require refactoring the doc generator...
Note: this also checks non-public functions, basically anything that
passes through `gen_eval_files.lua` and `gen_vimdoc.lua`. And that's
a good thing.
Problem
Some variables use the wrong type (ClientToServer instead of ServerToClient)
and some use vaguer types that could be more strict.
Solution
Use the correct types.
Problem: filetype: not all Bitbake include files are recognized
Solution: Enhance the file detection logic and consider varflags
(Martin Schwan)
closes: vim/vim#199830e02be1919
Co-authored-by: Martin Schwan <m.schwan@phytec.de>
Enable syntax highlighting for forward-slashes in Bitbake variables with
varflags. Bitbake allows for forward-slashes in both the variable name
and their potential varflags. E.g. the following should match:
FOO_BAR[baz] = "foobar"
FOO_BAR_foo/bar[baz] = "foobar"
FOO_BAR_foo/bar[baz/bazzer] = "foobar"
Also allow plus-signs in variable names, to be in line with normal
variable names.

Problem: runtime(tar): missing path traversal checks in tar#Extract()
Solution: Add check for leading slash, however gnu tar should already
detect this (q1uf3ng)
tar#Extract() did not check for ../ sequences or absolute paths,
unlike zip#Extract() which was patched in recent commits. Add the
same checks: ../ (relative traversal), leading slash (Unix), drive
letter and UNC/leading slash (Windows).

zip#Write(): the Windows path check did not match a single leading
slash (/path), which resolves to the current drive root on Windows.
Simplify the regex to match any leading slash or backslash.
zip#Extract(): add absolute path checks for both Unix and Windows,
matching the existing checks in zip#Write().

Problem:
The window opened by `vim.lsp.util.open_floating_preview()`
allows its buffer to be switched. Presumably that only happens
by accident and is disorienting.
Solution:
Set 'winfixbuf' in the open_floating_preview() window.

Problem:
To support `collapsedText`, which allows the LSP server to determine the
content of the foldtext, we provided `vim.lsp.foldtext()`. However, such
content does not have highlighting.
Solution
Treat the filetype of `collapsedText` as the filetype of the corresponding
buffer and use tree-sitter to highlight it.
In 3a4a66017b, 4d3a67cd62, df8d98173c we renamed "buffer" to "buf"
in dict parameters and return-values.

Extract the diagnostic implementation from
runtime/lua/vim/diagnostic.lua into focused internal modules covering
config, display, float rendering, jump/list helpers, namespace and
storage management, severity/shared utilities, and statusline support.
Move the builtin handlers into runtime/lua/vim/diagnostic/handlers/ and
keep runtime/lua/vim/diagnostic.lua as the public facade that lazily
dispatches to the split modules. This preserves the external
vim.diagnostic API while making the implementation easier to navigate
and reason about.

Replace the busted-based Lua test runner with a repo-local harness.
The new harness runs spec files directly under `nvim -ll`, ships its own
reporter and lightweight `luassert` shim, and keeps the helper/preload
flow used by the functional and unit test suites.
Keep the file boundary model shallow and busted-like by restoring `_G`,
`package.loaded`, `package.preload`, `arg`, and the process environment
between files, without carrying extra reset APIs or custom assertion
machinery.
Update the build and test entrypoints to use the new runner, add
black-box coverage for the harness itself, and drop the bundled
busted/luacheck dependency path.

Problem: The cursor shape is changed to indicate when it is behind an
unfocused floating window (since a2b92a5e). This behavior
cannot be controlled by a floating window that doesn't want
to dim the cursor.
Solution: Assign a zindex-offset of 50 to the zindex of the current
window. To not dim the cursor when creating a floating window
on top of the current window one can assign the zindex
accordingly.
Problem:
- Not obvious which _meta/ are generated and which should be edited
manually.
- The require guard (`error('Cannot require a meta file')`) is not
consistently present in all meta files.
Solution:
- Update headers.
- Add require() guard to all meta files.
- Rename generated meta files with `.gen.lua`.
Problem:
- Lots of redundant text in options docs for "not allowed in
a modeline", even though we already have a flag that indicates that.
- `deny_in_modelines` is an old vestigial flag only used by 'encoding'
(which never changes).
Solution:
- Generate docs based on the `secure` flag.
- Remove the `deny_in_modelines` flag (`kOptFlagNoML`).
Problem:
Neovim's Node.js provider does not support the Bun package manager.
PR #26829 attempted to add this but used a hardcoded path and was abandoned.
Solution:
- Use `bun pm bin -g` to dynamically locate the global binary directory.
- Update `health.lua` to recognize bun installations.
