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 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

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(system): use native path for Windows executables #40885

2026-07-21T11:58:44+00:00

Problem:
When 'shellslash' is set, exepath() returns forward-slashed paths.
Passing that path to vim.system() can prevent cmd.exe from launching.

Solution:
Convert the resolved executable path to native separators before spawning.
Add a Windows regression test for cmd.exe with 'shellslash' enabled.

fix(vim.system): use REAL PIPES for vim.system, similar to jobs

2026-04-30T10:22:57+00:00

This is essentially the #35991 fix for the #35984 issue,
but applied to vim.system().

build(deps): bump luv to 1.51.0-2

build: ship "_core/*" as bytecode (built-into Nvim binary)

2025-12-30T06:44:24+00:00

Problem:
We want to encourage implementing core features in Lua instead of C, but
it's clumsy because:
- Core Lua code (built into `nvim` so it is available even if VIMRUNTIME
  is missing/invalid) requires manually updating CMakeLists.txt, or
  stuffing it into `_editor.lua`.
- Core Lua modules are not organized similar to C modules, `_editor.lua`
  is getting too big.

Solution:
- Introduce `_core/` where core Lua code can live. All Lua modules added
  there will automatically be included as bytecode in the `nvim` binary.
- Move these core modules into `_core/*`:
  ```
  _defaults.lua
  _editor.lua
  _options.lua
  _system.lua
  shared.lua
  ```

TODO:
- Move `_extui/ => _core/ui2/`
