I always end up with that one customer who wants me to email them the PS1 file. I've always hated having to do the manual copy and rename, so let's automate it until they get actual source control.

tasks.json

{
  "version": "0.1.0",
  "tasks": [
    {
      "taskName": "build",
      "command": "powershell",
      "args": [
        "-ExecutionPolicy",
        "Unrestricted",
        "Merge-Script -Script '${file}' -Bundle -OutputPath '${fileDirname}\\out' -OutputType Script;",
        "Copy-Item -Path '${fileDirname}\\out\\\\${fileBasename}' -Destination '${fileDirname}\\out\\${fileBasenameNoExtension}.txt' -Force"        
      ],
      "isBuildCommand": true,
      "showOutput": "silent"
    }
  ]
}
