vscode remote: Interpolate environment variable to build editor link scheme?

[coezbek]

I am using Visual Studio Code under WSL remote. To build the URL for the editor link scheme I need to access an environment variable for the current distro being used. This works as an initializer, but I was hoping to contribute a patch to the KNOWN_EDITORS.

if defined?(BetterErrors)
  BetterErrors.editor = "vscode://vscode-remote/wsl+#{ENV['WSL_DISTRO_NAME']}%{file_unencoded}:%{line}"
end

Thanks for this @coezbek! I see that you added it to the wiki page already, which is what I would have recommended rather than adding to KNOWN_EDITORS, especially since your case uses an environment variable to assemble the URL. However, I would also recommend that you change your snippet to only be executed when that environment variable is set. i.e.

if defined?(BetterErrors) && (distro_name = ENV['WSL_DISTRO_NAME'])
  BetterErrors.editor = "vscode://vscode-remote/wsl+#{distro_name}%{file_unencoded}:%{line}"
end

One downside of this solution is that is isn't compatible with multiple users using different editors on the same codebase. That's why I asked.. (I updated the wiki with the improved snippet. Thank you!)
