fix(lua): enable param-type-mismatch diagnostic

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

Problem: Argument type mismatches are excluded from EmmyLua checks.

Solution: Correct runtime annotations and calls, document local checker
workarounds, and enable the diagnostic.

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(lua): add missing param annotations (#41911)

2026-09-15T13:14:21+00:00

fix(lsp): snippet is not expanded when resolve races the user #41774

2026-09-11T11:49:57+00:00

Problem:
on_complete_done() defers clear_word() and the snippet expansion until
completionItem/resolve answers, and drops both when 'changedtick' moved
meanwhile. Typing right after accepting leaves the plain word in the
buffer.

Solution:
Expand before requesting, and anchor the resolved edits with an extmark
instead of gating them on 'changedtick'.

build: enable more EmmyLua checks

2026-09-09T21:31:58+00:00

Enable checks for unused code, deprecated calls, return types, and
annotations.

Fix the warnings and replace the deprecated highlight function. Keep
exceptions where old APIs are still needed or the checker gets it wrong.

fix(lsp): show_document() reports a failed buffer load #41731

2026-09-07T16:21:11+00:00

Problem:
vim.lsp.util.show_document() can fail to load the target buffer, most
visibly with E325 when another process owns the file's swapfile and the
user declines to open it. The Vim error escapes show_document() and
surfaces inside whichever LSP handler called it, instead of being
reported as a failure to show the document.

Solution:
Load the buffer up front with vim.fn.bufload(), before any of that
state is touched, and report the error instead of raising.

build: replace LuaLS with EmmyLua

2026-09-07T14:33:22+00:00

Problem: LuaLS struggles with the generics used in Nvim's runtime,
requiring broad diagnostic suppressions. Indexing is also slow.

Solution: Use EmmyLua for type checks in the build and CI. It offers
more sophisticated type checking, substantially better support for
generics, and much better flow analysis.

Correct the affected annotations. Use `@internal`, supported directly by
EmmyLua, instead of `@nodoc` for shared internal declarations, and
support it in the help parser.

feat(fs): vim.fs.normalize{plain:boolean} #41127

2026-08-05T20:11:13+00:00

`opts.plain=true` does not expand tildes in addition to environment
variables, unlike `opts.expand_env=false`.

`opts.expand_env=false` is soft-deprecated.

fix(lsp): incorrect rendering of markdown codeblock #40861

2026-07-20T14:03:11+00:00

Problem:
LSP hover erroneously drops blank lines before a 4-space-indented
codeblock, which is not valid Markdown. This causes incorrect parsing
and wrong display.

Solution:
Fix `split_lines` so that it doesn't drop the blank line just before
a 4-space-indented codeblock.
