fix(vim.fs): find{follow=true} skips symlink targets of the given `type` #42246

2026-10-05T16:53:44+00:00

Problem:
`vim.fs.find()` checks `type` against the symlink itself, so
`{ type='file', follow=true }` skips symlinked files (e.g. `:helptags`).

Solution:
With `follow=true`, a symlink has the type of its target. Thus
`type='link'` only matches broken symlinks (like `find -L -type l`).

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): add missing param annotations (#41911)

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

fix(fs): honor the starting directory as an upward search stop #41886

2026-09-15T08:16:06+00:00

Problem:
An upward find() searches its initial directory before checking stop,
so path=stop can return a match or continue above the stop directory.
Downward search already stops before searching when path equals stop.

Solution:
Check the starting path before searching upward, matching the existing
downward search behavior.

refactor(help): reuse help.lua to generate build tags

2026-09-10T19:05:49+00:00

Make gen_helptags.lua call help.lua instead of keeping its own tag
parser. Builds and :helptags now use the same code.

Allow the shared code to run without Neovim, and fail the build when tag
generation reports an error.

perf(fs): defer path joining in find()

2026-09-10T12:57:10+00:00

Only join paths for matches and entries needed for traversal. This
avoids string processing for rejected files and improves selective
searches across the Neovim tree by about 19-25%.

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.
