| | | 2 | | .SYNOPSIS |
| | | 3 | | Defines or updates a global variable accessible across Kestrun scripts. |
| | | 4 | | |
| | | 5 | | .DESCRIPTION |
| | | 6 | | Stores a value in the Kestrun global variable table. Variables may be marked |
| | | 7 | | as read-only to prevent accidental modification. |
| | | 8 | | If the variable already exists, its value is updated. If it does not exist, |
| | | 9 | | it is created. |
| | | 10 | | .PARAMETER Server |
| | | 11 | | The Kestrun server instance. |
| | | 12 | | .PARAMETER Global |
| | | 13 | | If specified, the variable is stored in the global shared state. |
| | | 14 | | .PARAMETER Name |
| | | 15 | | Name of the variable to create or update. |
| | | 16 | | .PARAMETER Value |
| | | 17 | | Value to assign to the variable. |
| | | 18 | | .PARAMETER AllowsValueType |
| | | 19 | | If specified, allows the variable to hold value types (e.g., int, bool). |
| | | 20 | | .PARAMETER ThreadSafe |
| | | 21 | | If specified, the value is converted to a thread-safe representation. |
| | | 22 | | .EXAMPLE |
| | | 23 | | Set-KrSharedState -Name "MyVariable" -Value "Hello, World!" |
| | | 24 | | This creates a global variable "MyVariable" with the value "Hello, World!". |
| | | 25 | | .EXAMPLE |
| | | 26 | | Set-KrSharedState -Name "MyNamespace.MyVariable" -Value @{item=42} |
| | | 27 | | This creates a global variable "MyNamespace.MyVariable" with the value @{item=42}. |
| | | 28 | | .NOTES |
| | | 29 | | This function is part of the Kestrun.SharedState module and is used to define or update global variables. |
