fix(editorconfig): handle root separately from properties

2026-09-28T13:43:14+00:00

Problem: A child root=false masks a parent root=true during merging.

Solution: Return the search boundary separately from string properties.
Exclude root from property callbacks and b:editorconfig.

fix(lua): enable assignment type checking in runtime code

2026-09-25T16:07:21+00:00

Enable EmmyLua's assign-type-mismatch diagnostic after correcting the
runtime annotations and assignments it flags.

Correct option, tuple, and return types, and use separate locals when a
value changes representation. Add guards and narrow casts where needed
so the runtime passes the stricter check. Regenerate the affected docs.

fix(lua): enable nil-safety diagnostics in runtime code

2026-09-25T09:28:19+00:00

Enable EmmyLua's need-check-nil diagnostic and resolve nullable values
through more precise types, explicit invariants, and guards for missing
runtime state. Keep analyzer-specific workarounds local and update the
affected API documentation.

Exclude the bundled re.lua from analysis so its nil-check warnings do
not fail CI.

fix(editorconfig): avoid trim_trailing_whitespace in insert-mode #41175

2026-08-05T18:06:28+00:00

Problem:
During insert-mode / replace-mode, `autowrite` may trigger. If it does, the
cursor position can shift due to the automatic removal of trailing spaces on the
current line. When I resume typing, the space between the last word and the new
word is suddenly gone.

Solution:
Disable the "remove trailing spaces" handler during Insert (or a similar) mode.
Autosave logic is not affected.

refactor: introduce nvim_on internally #39883

2026-05-20T21:33:01+00:00

Problem:
`nvim_create_autocmd` is too verbose and its `callback` requires extra
"nesting".

Solution:
Introduce `nvim_on`. Start using it internally. Then we can get a feel
for how it should look before making it public.

build(lint): allow "bufnr" as positional param #39515

2026-04-30T11:12:35+00:00

Allow `bufnr` as a positional param name because it is very common.
However as a field name, or part of a function name, it is usually
a mistake.

feat(api): rename buffer to buf #35330

2026-04-09T00:34:47+00:00

Problem:
`:help dev-name-common` states that "buf" should be used instead of
"buffer" but there are cases where buffer is mentioned in the lua API.

Solution:
- Rename occurrences of "buffer" to "buf" for consistency with the
  documentation.
- Support (but deprecate) "buffer" for backwards compatibility.

refactor: integer functions, optimize asserts #34112

2026-03-12T15:04:05+00:00

refactor(lua): add integer coercion helpers

Add vim._tointeger() and vim._ensure_integer(), including optional base
support, and switch integer-only tonumber()/assert call sites in the Lua
runtime to use them.

This also cleans up related integer parsing in LSP, health, loader, URI,
tohtml, and Treesitter code.

fix(editorconfig): a custom property is treated as a section (#34445)

2025-06-11T13:26:38+00:00

Problem: A custom property containing a pair of square brackets will be
treated as a section.
Solution: Change the logic parsing a section, remove the first match
regex `%b[]`.
