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.

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.

refactor(lua): use vim.fs instead of fnamemodify

2026-01-28T10:57:39+00:00

Although powerful -- especially with chained modifiers --, the
readability (and therefore maintainability) of `fnamemodify()` and its
modifiers is often worse than a function name, giving less context and
having to rely on `:h filename-modifiers`. However, it is used plenty in
the Lua stdlib:

- 16x for the basename: `fnamemodify(path, ':t')`
- 7x for the parents: `fnamemodify(path, ':h')`
- 7x for the stem (filename w/o extension): `fnamemodify(path, ':r')`
- 6x for the absolute path: `fnamemodify(path, ':p')`
- 2x for the suffix: `fnamemodify(path, ':e')`
- 2x relative to the home directory: `fnamemodify(path, ':~')`
- 1x relative to the cwd: `fnamemodify(path, ':.')`

The `fs` module in the stdlib provides a cleaner interface for most of
these path operations: `vim.fs.basename` instead of `':t'`,
`vim.fs.dirname` instead of `':h'`, `vim.fs.abspath` instead of `':p'`.
This commit refactors the runtime to use these instead of fnamemodify.

Not all fnamemodify calls are removed; some have intrinsic differences
in behavior with the `vim.fs` replacement or do not yet have a
replacement in the Lua module, i.e. `:~`, `:.`, `:e` and `:r`.

fix(vim.diagnostic): improve typing

2025-06-03T19:25:07+00:00

Problem:

`vim.diagnostic.set()` doesn't actually accept a list of
`vim.Diagnostic` as internally `vim.diagnostic.set()` normalizes the
diagnostics and this normalization is assumed throughout the module.

Solution:

- Add a new type `vim.Diagnostic.Set` which is the input to `vim.diagnostic.set()`

- `col` is now an optional field and defaults to `0` to be consistent
  with `vim.diagnostic.match()`.

- Change `table.insert(t, x)` to `table[#table + 1] = x` for improved
  type checking.
