<# .SYNOPSIS Validate or show parameter set details with colored output .DESCRIPTION Analyze a function and it's parameters The cmdlet / function is capable of validating a string input with function name and parameters .PARAMETER CommandText The string that you want to analyze If there is parameter value present, you have to use the opposite quote strategy to encapsulate the string correctly E.g. for double quotes -CommandText 'Import-D365Bacpac -ImportModeTier2 -SqlUser "sqladmin" -SqlPwd "XyzXyz" -BacpacFile2 "C:\temp\uat.bacpac"' E.g. for single quotes -CommandText "Import-D365Bacpac -ExportModeTier2 -SqlUser 'sqladmin' -SqlPwd 'XyzXyz' -BacpacFile2 'C:\temp\uat.bacpac'" .PARAMETER Mode The operation mode of the cmdlet / function Valid options are: - Validate - ShowParameters .PARAMETER SplatInput Pass in your hashtable that you use for your command execution and have it validated .PARAMETER ShowSplatStyleV1 Include an hashtable splatting for all parameter sets in the output The example is built like this: PS C:\> $params = @{} PS C:\> $params.PropertyName = "SAMPLEVALUE" PS C:\> Test-FakeCommand @params .PARAMETER ShowSplatStyleV2 Include an hashtable splatting for all parameter sets in the output The example is built like this: PS C:\> $params = @{ PS C:\> PropertyName = "SAMPLEVALUE" PS C:\> } PS C:\> Test-FakeCommand @params .PARAMETER IncludeHelp Switch to instruct the cmdlet / function to output a simple guide with the colors in it .EXAMPLE PS C:\> Test-D365Command -CommandText 'Import-D365Bacpac -ImportModeTier2 -SqlUser "sqladmin" -SqlPwd "XyzXyz" -BacpacFile2 "C:\temp\uat.bacpac"' -Mode "Validate" -IncludeHelp This will validate all the parameters that have been passed to the Import-D365Bacpac cmdlet. All supplied parameters that matches a parameter will be marked with an asterisk. Will print the coloring help. .EXAMPLE PS C:\> Test-D365Command -CommandText 'Import-D365Bacpac' -Mode "ShowParameters" -IncludeHelp This will display all the parameter sets and their individual parameters. Will print the coloring help. .EXAMPLE PS C:\> $params = @{} PS C:\> $params.DatabaseName = "SAMPLEVALUE" PS C:\> Test-D365Command -CommandText 'Import-D365Bacpac -ImportModeTier2' -SplatInput $params -Mode "Validate" This builds a hashtable with a property names "DatabaseName". The hashtable is passed to the cmdlet to be part of the validation. .NOTES Author: Mötz Jensen (@Splaxi) #> function Test-D365Command { [CmdletBinding()] param ( [Parameter(Mandatory = $true, Position = 1)] [string] $CommandText, [Parameter(Mandatory = $true, Position = 2)] [ValidateSet('Validate', 'ShowParameters')] [string] $Mode, [hashtable] $SplatInput, [switch] $ShowSplatStyleV1, [switch] $ShowSplatStyleV2, [switch] $IncludeHelp ) $commonParameters = 'Verbose', 'Debug', 'ErrorAction', 'WarningAction', 'InformationAction', 'ErrorVariable', 'WarningVariable', 'InformationVariable', 'OutVariable', 'OutBuffer', 'PipelineVariable', 'Confirm', 'WhatIf' $colorParmsNotFound = "Red" $colorCommandName = "Green" $colorMandatoryParam = "Yellow" $colorNonMandatoryParam = "DarkGray" $colorFoundAsterisk = "Green" $colorNotFoundAsterisk = "Magenta" $colParmValue = "DarkCyan" $colorEqualSign = "DarkGray" $colorVariable = "Green" $colorProperty = "White" $colorCommandNameSplat = "Yellow" $colorComment = "DarkGreen" if(-not ($null -eq $SplatInput)) { $CommandText = "$CommandText "+ $(($SplatInput.Keys | ForEach-Object {"-$($_) `"$($SplatInput.Item($_))`""}) -Join " " ) } #Match to find the command name: Non-Whitespace until the first whitespace $commandMatch = ($CommandText | Select-String '\S+\s*').Matches if ($null -eq $commandMatch) { Write-PSFMessage -Level Host -Message "The function was unable to extract a valid command name from the supplied command text.
