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.

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): unclear error on malformed server responses #40422

2026-07-12T16:52:10+00:00

Problem:
Malformed server responses with `null` (vim.NIL) values, do not show
clear error messages.


Solution:
Assert two known, specific cases, to avoid user confusion.

feat(lua)!: vim.isnil, vim.nonnil, deprecate vim.F #39495

refactor(diagnostic): split diagnostic module

2026-04-15T13:44:13+00:00

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.
