How to Run Code.exe in PowerShell and Redirect Errors Efficiently

If you are a Visual Studio Code user who frequently utilizes PowerShell, you may have come across a common issue: error messages flooding the terminal when you invoke Code.exe. This can distract you from your workflow and reduce productivity. In this guide, we'll explore how to effectively run Code.exe from PowerShell, either by setting an alias or adjusting your $env:Path, while also managing those annoying error messages.

Understanding the Core Problem

Visual Studio Code (Code.exe) is often intended to be launched through its command line interface (CLI) entry point, which is a batch file named code.cmd. This file is located in the bin subdirectory where Code.exe is installed. Running Code.exe directly leads to unwanted diagnostic messages and error outputs that can clutter your terminal.

For instance, you might encounter messages like:

ERROR: Failed to append custom category 'Recent Folders & Workspaces' to Jump List due to system privacy settings.

WSL is not installed, so could not detect WSL profiles.

These errors can be frustrating, but fortunately, there are ways to suppress them while maintaining the functionality you need.

The Solution: Use code.cmd

Why Use code.cmd?

The code.cmd batch file is designed to handle the invocation of Visual Studio Code more gracefully than calling Code.exe directly. It automatically suppresses the asynchronous error messages that appear when you run Code.exe.

Steps to Use code.cmd

Locate code.cmd:
Ensure you know where code.cmd resides. It typically can be found in the bin directory next to Code.exe.

Set an Alias in PowerShell:
You can create an alias in PowerShell to make invoking code.cmd easier. Here’s how:

Replace C:\Path\To\Your\VSCode\bin\ with the actual path to the bin directory on your USB drive.

Add to $env:PATH:
Alternatively, you can add the bin directory to your $env:Path so that you can run code.cmd from any location.

Creating a Custom Wrapper Function (Advanced Option)

If you prefer or require invoking Code.exe directly, you can create a custom function that sets necessary environment variables and routes the command as follows:

Explanation:

Environment Variables: This function temporarily sets necessary environment variables to ensure Visual Studio Code runs correctly.

Arguments: The @ args section allows you to pass any additional arguments (like file names) directly when invoking the function.

Conclusion

By using code.cmd or creating a custom wrapper function, you can eliminate annoying error messages while maintaining access to Visual Studio Code's functionality. This allows for a smoother and more enjoyable coding experience in PowerShell.

Feel free to tweak these solutions based on your specific setup. Happy coding!
