Handles both insertion of new entries and updates to existing ones. Supports optional synchronization for non-local stores. This function implements an upsert operation that either inserts new key-value pairs or updates existing ones based on the combination of synchronization key, store name, and key name. .PARAMETER StoreName The name of the store where the key-value pair will be saved. .PARAMETER KeyName The unique identifier for the value within the specified store. .PARAMETER Value The data to be stored, associated with the specified key. .PARAMETER SynchronizationKey Identifies the synchronization scope. Use "Local" for local-only storage. Defaults to "Local". Non-local values trigger store synchronization. .PARAMETER DatabasePath Database path for key-value store data files. .EXAMPLE Set-ValueByKeyInStore -StoreName "ConfigStore" -KeyName "ApiEndpoint" ` -Value "https://api.example.com" .EXAMPLE setvalue ConfigStore ApiEndpoint "https://api.example.com" #> function Set-ValueByKeyInStore { [CmdletBinding(SupportsShouldProcess = $true)] [Alias('setvalue')] param ( ############################################################################### [Parameter( Mandatory = $true, Position = 0, HelpMessage = 'Store name for the key-value pair' )] [string]$StoreName, ############################################################################### [Parameter( Mandatory = $true, Position = 1, HelpMessage = 'Name of the key to set or update' )] [string]$KeyName, ############################################################################### [Parameter( Mandatory = $false, Position = 2, HelpMessage = 'Value to be stored' )] [string]$Value, ############################################################################### [Parameter( Mandatory = $false, Position = 3, HelpMessage = 'Key to identify synchronization scope' )] [string]$SynchronizationKey = 'Local', ############################################################################### [Parameter( Mandatory = $false, HelpMessage = 'Database path for key-value store data files' )] [string]$DatabasePath ############################################################################### ) begin { # use provided base path or default to local app data if ([string]::IsNullOrWhiteSpace($DatabasePath)) { $basePath = "$($ENV:LOCALAPPDATA)\GenXdev.PowerShell\KeyValueStore" } else { $basePath = $DatabasePath } Microsoft.PowerShell.Utility\Write-Verbose ( "Using KeyValueStore directory: $basePath") } process { # ensure store directory structure exists if (-not (Microsoft.PowerShell.Management\Test-Path -LiteralPath $basePath)) { Microsoft.PowerShell.Utility\Write-Verbose ( 'Store directory not found.
