| # $PSStyle polyfill for Windows PowerShell: | |
| # When run on a PS v7.2+ system, generates source code for Windows PowerShell | |
| # that creates a nested ordered hashtable that mimics the v7.2+ $PSStyle object, | |
| # albeit only with respect to the properties with general-purpose ANSI (VT) | |
| # escape sequences, such as $PSStyle.Italic and $PSStyle.Foreground.Yellow | |
| # | |
| # Simply copy and paste this snippet and execute it in a PowerShell 7.2+ session, | |
| # and it will output source code for Windows PowerShell that defines $PSStyle. | |
