#Requires -Modules @{ ModuleName="EPS"; ModuleVersion="1.0.0" } Function Build-GitOpsSource { <# .SYNOPSIS Parses the Source directory, processes each file based on extension, then puts the resulting file in into the Build. .DESCRIPTION The 'Build-GitOpsSource' function checks each file in the Source. The processes the file based on the file name. Template files are processed through the EPS module. Specto files are only copied if the SpectoCommon AND SpectoSignature strings are in the file name. All other files are simply copied. Files whose path matches the Exclude regex are skipped. .PARAMETER Source The Directory that will be parsed recursively. .PARAMETER Build The Directory that will store the resulting files. .PARAMETER Destination Not Used in this function. Added for splatting purposes. .PARAMETER Exclude A Regular Expression used to identify the files that should not be processed. This is matched against the full path of the source file. .PARAMETER TemplateExtension If a file ends with this extension, it is considered a Template file to be processed through Invoke-EpsTemplate. The TemplateExtension is removed from the destination file name. .PARAMETER TemplateBinding A hashtable that is passed into Invoke-EpsTemplate. Variables in this hashtable are made available to the Template files. .PARAMETER SpectoCommon The string that identifies the common signature used to identify Specto files. If a file contains this string in its name it will be processed through the Specto logic. The Specto logic will check the end of the file name for the SpectoSignature, if it doesn't match, it is not copied. If it does, it is copied with SpectoCommon and SpectoSignature removed from the name. .PARAMETER SpectoSignature The string used to identify a Specto file as one that needs to be copied. .PARAMETER WithTemplateDiff When used in combination with Verbose it includes the the output of `git diff --no-index Source Destination` when doing This aids in the troublshooting of Template files. .INPUTS System.IO.DirectoryInfo can be piped into Source. .OUTPUTS None .LINK EPS ( Embedded PowerShell ) https://github.com/straightdave/eps .COMPONENT EPS #> [CmdletBinding(SupportsShouldProcess = $true)] param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true)] [ValidateScript( { Test-Path $_ -PathType Container })] [String] $Source, [ValidateScript( { Test-Path $_ -IsValid -PathType Container })] [String] $Build = $env:TEMP, [String] $Destination, [Regex] $Exclude = '^.*\.md$', [String] $TemplateExtension = ".eps1", [hashtable] $TemplateBinding = @{}, [String] $SpectoCommon = ".specto", [String] $SpectoSignature, [Switch] $WithTemplateDiff ) Process { Write-Verbose "Set Location to $Source to provide context for git commands."
