A script that allows you to open workspaces in Code - OSS via rofi, e.g: "rofi -modes drun,window,code-workspaces:~/bin/code-workspaces.sh -show drun". You need ripgrep and awk available in $PATH.

rofi-code-workspaces.sh

#!/bin/bash

pushd () {
	command pushd "$@" > /dev/null
}

popd () {
	command popd "$@" > /dev/null
}

if [ $# -eq 0 ]
	then
		pushd ~/.config/Code\ -\ OSS/User/workspaceStorage && rg ".code-workspace" | awk '{print substr($3,9,length($3)-24);}' | sort && popd

	else
		WORKSPACEFILE="$1"
		WORKSPACEEXTENSION=".code-workspace"
		FULLWORKSPACEFILE="$WORKSPACEFILE$WORKSPACEEXTENSION"
		code $FULLWORKSPACEFILE > /dev/null
fi

very good job!
