Description

Summary

Please consider providing pre-built binaries for Windows ARM64 (aarch64) in the release artifacts.

Motivation

Windows on ARM devices (e.g., Surface Pro X, Snapdragon-based laptops, Windows Dev Kit 2023) are becoming increasingly common. Currently, only win32-x64 binaries are provided, which work via x86-64 emulation but come with a performance penalty.

Tools like Mason.nvim use strict platform matching and refuse to install lua-language-server on win-arm64 because no native binary is available, resulting in:

Installation failed for Package(name=lua-language-server) error="The current platform is unsupported."

Current workaround

Installing the x64 build manually (e.g., via winget install LuaLS.lua-language-server) works under emulation, but native ARM64 binaries would be preferred for performance and broader tooling compatibility.

Request

Add win32-arm64 (or win-arm64) to the release build matrix.

  4. Open a pull request that references the issue number.

Research direction

Start by inspecting the existing release build matrix that produces the win32-x64 artifacts and identify how platform targets are configured. Add the Windows ARM64 target, then verify that release artifacts include a native win-arm64 or win32-arm64 binary usable by Mason.nvim.
