What is the issue affecting?

Annotations

Expected Behaviour

Running lua-language-server --version should return x.x.x

Actual Behaviour

Running lua-language-server --version returns <Unknown>

Reproduction steps

1. Install lua-language-server via homebrew
2. Run lua-language-server --version
3. See ''

Additional Notes

Running brew list --versions I can see that I have v3.14.0 installed. However, running lua-language-server --version from the command line returns <Unknown>.

This comports with the readout from running :LspInfo within neovim:

- lua_ls (id: 1)
  - Version: <Unknown>
  - Root directory: ~/.config/nvim
  - Command: { "lua-language-server" }
  - Settings: {
      Lua = {
        runtime = {
          version = "LuaJIT"
        },
        workspace = {
          checkThirdParty = false,
          library = { "/opt/homebrew/Cellar/neovim/0.11.1/share/nvim/runtime", "${3rd}/luv/library" }
        }
      }
    }

Looking at LuaLS's source code, the version is read from changelog.md.
I don't know if this is the normal practice, but currently LuaLS is doing this way. 🙈

lua-language-server/script/version.lua

Lines 3 to 24 in 759e8fb

	local function loadVersion()
	local changelog = fsu.loadFile(ROOT / 'changelog.md')
	if not changelog then
	return
	end
	local version, pos = changelog:match '%#%# (%d+%.%d+%.%d+)()'
	if not version then
	return
	end
	if not changelog:find('^[\r\n]+`', pos) then
	version = version .. '-dev'
	end
	return version
	end
	local m = {}
	function m.getVersion()
	if not m.version then
	m.version = loadVersion() or '<Unknown>'

Seems that the installation from brew is missing this changelog.md, so the server cannot find the version 🤔 .
Meanwhile I believe the homebrew package is NOT maintained by authors of LuaLS (?) #232 (comment)

• https://formulae.brew.sh/formula/lua-language-server
• https://github.com/Homebrew/homebrew-core/blob/2f3fe11a058ccc5938c63824609fb38772431525/Formula/l/lua-language-server.rb

Maybe you have to report to homebrew-core repo instead ?
Or you may try to @ mention recent contributor of the above formula file to see if they can provide some quick fixes for it. 👀
