2118### emacsdc
2119
2120Here's a wrapper script that'll start `emacs --daemon` if there isn't
2121one, and then launch `emacsclient` with the arguments. I'd recommend
2122installing with either `ln -s bin/emacsdc $HOME/.local/bin/`, or
2123adding `$HOME/.local/bin` to your `$PATH`.
2124
2125 if ! emacsclient -nc "$@" 2>/dev/null; then
2126 emacs --daemon
2127 emacsclient -nc "$@"
2128 fi
2129
2130
2131### Emacs.cmd
2132
2133Here's a wrapper script that'll run Emacs on Windows, with a
2134custom `$HOME`. I have mine setup like this: Emacs is downloaded
2135from [the GNU mirror](https://mirrors.tripadvisor.com/gnu/emacs/windows/emacs-27/emacs-27.1-x86_64.zip) and unzipped to `~/Downloads/emacs/`. For
2136some reason, Emacs by default sets `$HOME` to `%APPDATA%`, which
2137doesn’t make a lot of sense to me. I change it to
2138`%USERPROFILE%\Downloads\home`, and then run Emacs with the
2139supplied arguments.
2140
2141As far as creating a shortcut to the Desktop, you’ll have to do
2142that yourself – *apparently* Windows doesn’t have a built-in
2143shortcut-creating software >:(.
2144
2145 REM Set variables
2146 set HOME=%USERPROFILE%\Downloads\home
2147 set EMACS=%USERPROFILE%\Downloads\emacs\bin\runemacs.exe
