Batch Script Sidecar on Windows

[psavery]

For Linux and and Mac, we are able to use bash scripts for sidecars by
making the files executable and starting them with the shebang #!/bin/bash.

We would like to similarly use a batch script on Windows. But it seems that
the .exe extension is mandatory and added automatically. Is there any way
we can run a command or a batch script within a sidecar definition?

For additional context, we are bundling our server as resources (which
rely on relative paths internally) using PyInstaller, and those bash scripts for Mac
and Linux were used to resolve the os-arch (rustc -Vv | grep host | cut -f2 -d' ')
specificity for the sidecar executable. But on Windows, we would like to run a file
with a .bat extension instead of a .exe extension.

On Linux, we have a file named trame-x86_64-unknown-linux-gnu with the contents:

#!/bin/bash
rootdir=`dirname "$0"`
cd "$rootdir"
cd ../lib/cone/server/

./server $@

Similarly on Mac, we have a file named trame-aarch64-apple-darwin with the contents:

#!/bin/bash
rootdir=`dirname "$0"`
cd "$rootdir"
cd ../Resources/server

./server $@

And on Windows, we were hoping to run a trame-x86_64-pc-windows-msvc.bat file with the contents:

cd %~dp0

server\server %*

But since the .exe is added to the end, we cannot do this.

We are not rust experts, and this is how we are currently running our server:

      let (mut rx, _) = Command::new_sidecar("trame")
        .expect("failed to create sidecar")
        .args(["--server", "--port", "0", "--timeout", "10"])
        .spawn()
        .expect("Failed to spawn server");

Maybe we can do something Windows-specific where we actually run the command line?

I have found a work-around: I was able to create a stand-alone executable from C++ that essentially does the same thing as the batch file.

I'm going to close this, but if anyone recommends any simpler way, feel free to comment.
