def self.desktop_path
  return @desktop_path if defined?(@desktop_path)

  @desktop_path = case os_type
  when :wsl
    wsl_desktop_path
  when :macos
    macos_desktop_path
  when :linux
    linux_desktop_path
  else
    fallback_desktop_path
  end
end

.linux_to_win_path(path) ⇒ String

Convert a Linux-side path to a Windows-style path via wslpath. e.g. “/mnt/c/Users/foo/file.txt” → “C:Usersfoofile.txt” Returns the original path unchanged on non-WSL.

Parameters:

  • path (String)

Returns:

  • (String)

def self.linux_to_win_path(path)
  return path unless os_type == :wsl

  Clacky::Utils::Encoding.cmd_to_utf8(
    `wslpath -w '#{path.gsub("'", "'\''")}'`,
    source_encoding: "UTF-8"
  ).strip
end

.open_file(path) ⇒ Boolean?

Open a file with the OS-default application. On WSL, uses “cmd.exe /c start” instead of explorer.exe so the opened window receives foreground focus even when called from a background thread (e.g. WEBrick request handler).

Parameters:

  • path (String) —

    Linux-side file path

Returns:

  • (Boolean, nil) —

    true/false from system(), or nil on unsupported OS

.win_to_linux_path(path) ⇒ String
