How to Use 1Password SSH Agent with WSL2 (on Windows 11)

Note:
- Always look for the official documentation, this tutorial may not suit you as there are new updates to the installation process.
- References are at the end of the document.
Was used:
- Windows 11 (x64)
- WSL 2 (Ubuntu 22.04.2 LTS)

SSH Agent forwarding in WSL2

Download npiperelay

To communicate between WSL and the 1Password SSH agent, we'd need to use npiperelay. This tool allows WSL to communicate with Windows' named pipes.

To install it, we need to open the GitHub repository and download the latest release. At the time of writing this post the latest release is v0.1.0 from July 2, 2020.

Unzip it and paste the npiperelay.exe file in any folder that's configured in your system's PATH. For example %USERPROFILE%/.wsl/mpiperelay.exe and then add %USERPROFILE%/.wsl to your PATH.

SpringEl fail the third time

The First Look

Our project use springel to evaluate expressions and one strange error happens. It seems like that the first two evaluations are always successful, however when it comes to the third time the evaluation begins to fail. After tracing down the source code we find the reason.

/**
 * Compile the expression if it has been evaluated more than the threshold number
 * of times to trigger compilation.
