Function Out-IniFile { <# .Synopsis Write hash content to INI file .Description Write hash content to INI file .Notes Author : Oliver Lipkau <oliver@lipkau.net> Blog : http://oliver.lipkau.net/blog/ Source : https://github.com/lipkau/PsIni http://gallery.technet.microsoft.com/scriptcenter/ea40c1ef-c856-434b-b8fb-ebd7a76e8d91 Version : 1.0.0 - 2010/03/12 - OL - Initial release 1.0.1 - 2012/04/19 - OL - Bugfix/Added example to help (Thx Ingmar Verheij) 1.0.2 - 2014/12/11 - OL - Improved handling for missing output file (Thx SLDR) 1.0.3 - 2014/01/06 - CB - removed extra \r\n at end of file 1.0.4 - 2015/06/06 - OL - Typo (Thx Dominik) 1.0.5 - 2015/06/18 - OL - Migrate to semantic versioning (GitHub issue#4) 1.0.6 - 2015/06/18 - OL - Remove check for .ini extension (GitHub Issue#6) 1.1.0 - 2015/07/14 - CB - Improve round-tripping and be a bit more liberal (GitHub Pull #7) OL - Small Improvments and cleanup #Requires -Version 2.0 .Inputs System.String System.Collections.IDictionary .Outputs System.IO.FileSystemInfo .Parameter Append Adds the output to the end of an existing file, instead of replacing the file contents. .Parameter InputObject Specifies the Hashtable to be written to the file. Enter a variable that contains the objects or type a command or expression that gets the objects. .Parameter FilePath Specifies the path to the output file. .Parameter Encoding Specifies the file encoding. The default is UTF8. Valid values are: -- ASCII: Uses the encoding for the ASCII (7-bit) character set. -- BigEndianUnicode: Encodes in UTF-16 format using the big-endian byte order. -- Byte: Encodes a set of characters into a sequence of bytes. -- String: Uses the encoding type for a string. -- Unicode: Encodes in UTF-16 format using the little-endian byte order. -- UTF7: Encodes in UTF-7 format. -- UTF8: Encodes in UTF-8 format. .Parameter Force Allows the cmdlet to overwrite an existing read-only file. Even using the Force parameter, the cmdlet cannot override security restrictions. .Parameter PassThru Passes an object representing the location to the pipeline. By default, this cmdlet does not generate any output. .Parameter Loose Adds spaces around the equal sign when writing the key = value .Example Out-IniFile $IniVar "C:\myinifile.ini" ----------- Description Saves the content of the $IniVar Hashtable to the INI File c:\myinifile.ini .Example $IniVar | Out-IniFile "C:\myinifile.ini" -Force ----------- Description Saves the content of the $IniVar Hashtable to the INI File c:\myinifile.ini and overwrites the file if it is already present .Example $file = Out-IniFile $IniVar "C:\myinifile.ini" -PassThru ----------- Description Saves the content of the $IniVar Hashtable to the INI File c:\myinifile.ini and saves the file into $file .Example $Category1 = @{“Key1”=”Value1”;”Key2”=”Value2”} $Category2 = @{“Key1”=”Value1”;”Key2”=”Value2”} $NewINIContent = @{“Category1”=$Category1;”Category2”=$Category2} Out-IniFile -InputObject $NewINIContent -FilePath "C:\MyNewFile.ini" ----------- Description Creating a custom Hashtable and saving it to C:\MyNewFile.ini .Link Get-IniContent #> [CmdletBinding()] Param( [switch]$Append, [ValidateSet("Unicode","UTF7","UTF8","ASCII","BigEndianUnicode","Byte","String")] [Parameter()] [string]$Encoding = "UTF8", [ValidateNotNullOrEmpty()] [ValidateScript({Test-Path $_ -IsValid})] [Parameter(Mandatory=$True, Position=0)] [string]$FilePath, [switch]$Force, [ValidateNotNullOrEmpty()] [Parameter(ValueFromPipeline=$True,Mandatory=$True)] [System.Collections.IDictionary]$InputObject, [switch]$Passthru, [switch]$Loose ) Begin { Write-Verbose "$($MyInvocation.MyCommand.Name):: Function started" function Out-Keys { param( [ValidateNotNullOrEmpty()] [Parameter(ValueFromPipeline=$True,Mandatory=$True)] [System.Collections.IDictionary]$InputObject, [ValidateSet("Unicode","UTF7","UTF8","ASCII","BigEndianUnicode","Byte","String")] [Parameter(Mandatory=$True)] [string]$Encoding = "UTF8", [ValidateNotNullOrEmpty()] [ValidateScript({Test-Path $_ -IsValid})] [Parameter(Mandatory=$True, ValueFromPipelineByPropertyName=$true)] [string]$Path, [Parameter(Mandatory=$True)] $delimiter, [Parameter(Mandatory=$True)] $MyInvocation ) Process { Foreach ($key in $InputObject.keys) { if ($key -match "^Comment\d+") { Write-Verbose "$($MyInvocation.MyCommand.Name):: Writing comment: $key" Add-Content -Value "$($InputObject[$key])" @parameters } else { Write-Verbose "$($MyInvocation.MyCommand.Name):: Writing key: $key" Add-Content -Value "$key$delimiter$($InputObject[$key])" @parameters } } } } $delimiter = '=' if ($Loose) { $delimiter = ' = ' } if ($append) {$outfile = Get-Item $FilePath} else {$outFile = New-Item -ItemType file -Path $Filepath -Force:$Force} if (!(Test-Path $outFile.FullName)) {Throw "Could not create File"} #Splatting Parameters $parameters = @{ Encoding = $Encoding; Path = $FilePath } } Process { Write-Verbose "$($MyInvocation.MyCommand.Name):: Writing to file: $Filepath" foreach ($i in $InputObject.keys) { if (!($InputObject[$i].GetType().GetInterface('IDictionary'))) { #No Sections Write-Verbose "$($MyInvocation.MyCommand.Name):: Writing key: $i" Add-Content -Value "$i$equal$($InputObject[$i])" ` @parameters } elseif ($i -eq '_') { Out-Keys $InputObject[$i] ` @parameters ` -delimiter $delimiter ` -MyInvocation $MyInvocation } else { #Sections Write-Verbose "$($MyInvocation.MyCommand.Name):: Writing Section: [$i]" Add-Content -Value "[$i]" ` @parameters Out-Keys $InputObject[$i] ` @parameters ` -delimiter $delimiter ` -MyInvocation $MyInvocation Add-Content -Value "" ` @parameters } } Write-Verbose "$($MyInvocation.MyCommand.Name):: Finished Writing to file: $FilePath" } End { if ($PassThru) { Return (Get-Item $outFile) } Write-Verbose "$($MyInvocation.MyCommand.Name):: Function ended" } } |
