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(loader): use the statistic name when printing its heading #41887

2026-09-12T22:50:30+00:00

Problem:
Printing loader statistics concatenates the statistics table into the
heading, raising an error before displaying the results.

Solution:
Use the iteration key for the heading. Cover printing loader statistics.

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.

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.

fix(loader): remove all cached loaders on disable #41613

2026-09-02T14:08:37+00:00

Problem:
When disabling, the loader list is traversed forwards while entries are
removed. As a result, some entries are skipped and remain active. Thus,
disabling `vim.loader` restores `_G.loadfile`, but does not fully
restore the original package loader chain.

Solution:
Traverse `package.loaders` in reverse when removing cached loaders.
Capture the original `package.loaders` list in the test, and assert that
the list is restored properly.

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.

refactor(api): omit optional param
