function New-PSMDFormatTableDefinition { <# .SYNOPSIS Generates a format XML for the input type. .DESCRIPTION Generates a format XML for the input type. Currently, only tables are supported. Note: Loading format files has a measureable impact on module import PER FILE. For the sake of performance, you should only generate a single file for an entire module. .PARAMETER InputObject The object that will be used to generate the format XML for. Will not duplicate its work if multiple object of the same type are passed. .PARAMETER IncludeProperty Only properties in this list will be included. .PARAMETER ExcludeProperty Only properties not in this list will be included. .PARAMETER Fragment The function will only return a partial Format-XML object. This is useful when combining multiple objects into a single file: Simply create a full format XML for the first type, then use fragments on the subsequent ones and paste them into the first one's structure. .EXAMPLE PS C:\> Get-ChildItem | New-PSMDFormatTableDefinition Generates a format xml for the objects in the current path (files and folders in most cases) .EXAMPLE PS C:\> Get-ChildItem | New-PSMDFormatTableDefinition -IncludeProperty LastWriteTime, FullName Creates a format xml that only includes the columns LastWriteTime, FullName #> [CmdletBinding()] Param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true)] $InputObject, [string[]] $IncludeProperty, [string[]] $ExcludeProperty, [switch] $Fragment ) begin { $typeNames = @() #region Xml Definitions $xmlFull = @" <?xml version="1.0" encoding="utf-16"?> <Configuration> <ViewDefinitions> <!-- %TypeName% --> <View> <Name>%TypeName%</Name> <ViewSelectedBy> <TypeName>%TypeName%</TypeName> </ViewSelectedBy> <TableControl> <AutoSize/> <TableHeaders> %Headers% </TableHeaders> <TableRowEntries> <TableRowEntry> <TableColumnItems> %Columns% </TableColumnItems> </TableRowEntry> </TableRowEntries> </TableControl> </View> </ViewDefinitions> <Configuration> "@ $xmlFragment = @" <!-- %TypeName% --> <View> <Name>%TypeName%</Name> <ViewSelectedBy> <TypeName>%TypeName%</TypeName> </ViewSelectedBy> <TableControl> <AutoSize/> <TableHeaders> %Headers% </TableHeaders> <TableRowEntries> <TableRowEntry> <TableColumnItems> %Columns% </TableColumnItems> </TableRowEntry> </TableRowEntries> </TableControl> </View> "@ $xmlColumnHeaderItem = " <TableColumnHeader/>" $xmlColumnItem = @" <TableColumnItem> <PropertyName>%PropertyName%</PropertyName> </TableColumnItem> "@ #endregion Xml Definitions } process { foreach ($object in $InputObject) { if ($object.PSObject.TypeNames[0] -in $typeNames) { continue } else { $typeNames += $object.PSObject.TypeNames[0] } $typeName = $object.PSObject.TypeNames[0] $propertyNames = $object.PSOBject.Properties.Name if ($IncludeProperty) { $propertyNames = $propertyNames | Where-Object { $_ -in $IncludeProperty } } if ($ExcludeProperty) { $propertyNames = $propertyNames | Where-Object { $_ -notin $ExcludeProperty } } if ($Fragment) { $baseXml = $xmlFragment } else { $baseXml = $xmlFull } $baseHeader = ( ,$xmlColumnHeaderItem * $propertyNames.Count) -join ([System.Environment]::NewLine) $columns = @() foreach ($property in $propertyNames) { $columns += $xmlColumnItem -replace "%PropertyName%", $property } $baseColumn = $columns -join ([System.Environment]::NewLine) $baseXml -replace "%TypeName%", "$typeName" -replace "%Headers%", $baseHeader -replace "%Columns%", $baseColumn } } end { } } |
