Need to work around Windows is lacking eval equivalent

[synfinatic]

TL;DR: Windows CommandPrompt & PowerShell have no equivalent of bash's eval command so you can't do eval $(aws-sso eval ...) and have it update the environment variables for the current shell/CommandPrompt.

Using setx is not viable either.

The only way I see to do this right now is to generate a batch script that the user can run and then it would delete itself. But this means we would write the AWS secrets to disk which is violating the basic premise of aws-sso. Need to figure out if there is another way to do this?

In powershell there is an equivalent to eval, and it's Invoke-Expression. It can be chained, so something like this should work: aws-sso eval -p 1234:role | Out-String | Invoke-Expression

The Out-String is required to convert the object output to a string (I think).

The environment variables would be output in this style:

$Env:AWS_ACCESS_KEY_ID = "zzzz"
$Env:AWS_SECRET_ACCESS_KEY = "zzzz"
$Env:AWS_SESSION_TOKEN = "zzzz"
