Function Get-WordCombinations { <# .SYNOPSIS This function helps to find string permutations and it's synonyms. .DESCRIPTION This script is designed to work with String Manager class which ideally provides the functionalities of picking alphabets randomly and form a word with that, finding the factorial(or number of possible combinations that can be made with the word.), string permutations and synonyms for the formed words. This script is intended to get input from user to choose the number of alphabets to pick from alphabets library, find it's permutations and retrieve synonyms for the formed words. .PARAMETER Number Provide the number to pick up alphabets randomly. .PARAMETER LogPath Provide the path to save log files. .EXAMPLE Get-WordCombinations -Number 3 -LogPath "C:\TEMP" -Verbose .EXAMPLE Get-WordCombinations -Number 3 -LogPath "C:\TEMP" .EXAMPLE Get-WordCombinations -Number 3 .EXAMPLE Get-WordCombinations .NOTES Author Version Date Notes -------------------------------------------------------------------------------------------------------------------- harish.b.karthic v1.0 02/01/2020 Initial script #> [CmdletBinding()] Param( [Parameter(Mandatory=$false)] [int]$Number, [Parameter(Mandatory=$false)] [string]$LogPath ) begin { # initialise function variables $functionName = $MyInvocation.MyCommand.Name if (-not $PSBoundParameters.ContainsKey("Number")) { $Number = Read-Host "Enter the number to select alphabets from alphabets library " } if (-not $PSBoundParameters.ContainsKey("LogPath")) { $LogFile = $env:TEMP + "\GetWordCombinations_$(Get-Date -Format ddMMyyyy).log" } else { $LogFile = $LogPath + "\GetWordCombinations_$(Get-Date -Format ddMMyyyy).log" } $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Begin function" Write-Verbose $Message ; $Message | Out-File -Append $LogFile } process { try { $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Trying to process the given number $($Number)" Write-Verbose $Message ; $Message | Out-File -Append $LogFile # Instantiating the class $StringManagerClass = [StringManager]::new($Number) $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Picking random alphabets" Write-Verbose $Message ; $Message | Out-File -Append $LogFile # Picking random alphabets $Word = $StringManagerClass.GetRandomAlphabets($StringManagerClass.Number) $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Picked [ $($Word) ] from library" Write-Verbose $Message ; $Message | Out-File -Append $LogFile $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Getting number of possible combinations from [ $($Word) ]" Write-Verbose $Message ; $Message | Out-File -Append $LogFile # Getting number of combinations from the picked word $Factorial = $StringManagerClass.GetFactorial($Word.Length) $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : [ $($Factorial) ] combinations can be formed from the word [ $($Word) ]" Write-Verbose $Message ; $Message | Out-File -Append $LogFile $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Removing duplicate alphabets if any in [ $($Word) ]" Write-Verbose $Message ; $Message | Out-File -Append $LogFile # Removing duplicate letter from word $repeatedword = $StringManagerClass.RemoveDuplicateLetters($Word) $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Finding all possible combinations from picked word [ $($Word) ]" Write-Verbose $Message ; $Message | Out-File -Append $LogFile # Generating all possible permutations of the word $Permutations = $StringManagerClass.GetPermutations($repeatedword) $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : String Permutations formed are : [ $($Permutations -Join ",") ]" Write-Verbose $Message ; $Message | Out-File -Append $LogFile $Message = "[$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : Getting synonyms for meaningful words" Write-Verbose $Message ; $Message | Out-File -Append $LogFile # Getting synonyms for generated permutations $Synonyms = $StringManagerClass.GetSynonyms($Permutations) } catch { Write-Verbose " [$(Get-Date -UFormat %Y/%m/%d_%H:%M:%S)] $functionName : $($_.Exception.Message).."
