<# .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 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. .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, [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" #Match to find the command name: Non-Whitespace until the first whitespace $commandMatch = ($CommandText | Select-String '\S+\s*').Matches if (-not ($null -eq $commandMatch)) { $commandName = $commandMatch.Value.Trim() $res = Get-Command $commandName -ErrorAction Ignore if (-not ($null -eq $res)) { $null = $sbHelp = New-Object System.Text.StringBuilder $null = $sbParmsNotFound = New-Object System.Text.StringBuilder switch ($Mode) { "Validate" { #Match to find the parameters: Whitespace Dash Non-Whitespace $inputParameterMatch = ($CommandText | Select-String '\s{1}[-]\S+' -AllMatches).Matches if (-not ($null -eq $inputParameterMatch)) { $inputParameterNames = $inputParameterMatch.Value.Trim("-", " ") } else { Write-PSFMessage -Level Host -Message "The function was unable to extract any parameters from the supplied command text.
