Open Visual Studio Code or VSCodium from a remote host

rcode.sh

#!/bin/bash

# This is like "code" or "codium" but on a remote device. Often when I'm writing something on a Raspberry Pi 
# it can be useful to open the current folder in VSC or VSCodium on a different machine

PROJPATH="$(pwd)"

# for VSCode on macOS change to RCOMMAND="/Applications/Visual Studio Code.app/Contents/Resources/app/bin/code"
RCOMMAND="codium"

# change to device where VSC or VSCodium should be opened, this should be setup with passwordless (key-based) logins
RHOST="my_remote_host"

# allow other paths to be passed in as an argument
if [[ ${#1} -gt 0 ]]; then
	PROJPATH=$(realpath "$1")
fi

if [[ ! -d "$PROJPATH" ]]; then
	echo "Error: can not find project path \"$PROJPATH\""
	exit 1
fi

#escape paths / commands that have spaces
PROJPATH=$(printf %q "$PROJPATH")
RCOMMAND=$(printf %q "$RCOMMAND")

# this could be hardcoded if necessary, this works for me
HNAME=$(hostname)

# print the command this is running
echo "ssh $RHOST \"$RCOMMAND --folder-uri vscode-remote://ssh-remote+$HNAME$PROJPATH\""

# set JUSTPRINT to exit here and not actually run the remote command
if [[ -z ${JUSTPRINT+x} ]]; then
	ssh $RHOST "$RCOMMAND --folder-uri vscode-remote://ssh-remote+$HNAME$PROJPATH"
fi
