.SYNOPSIS This is a build task that generates conceptual help. .PARAMETER ProjectPath The root path to the project. Defaults to $BuildRoot. .PARAMETER OutputDirectory The base directory of all output. Defaults to folder 'output' relative to the $BuildRoot. .PARAMETER BuiltModuleSubdirectory Sub folder where you want to build the Module to (instead of $OutputDirectory/$ModuleName). This is especially useful when you want to build DSC Resources, but you don't want the `Get-DscResource` command to find several instances of the same DSC Resources because of the overlapping $Env:PSmodulePath (`$buildRoot/output` for the built module and `$buildRoot/output/RequiredModules`). In most cases I would recommend against setting $BuiltModuleSubdirectory. .PARAMETER VersionedOutputDirectory Whether the Module is built with its versioned Subdirectory, as you would see it on a System. For instance, if VersionedOutputDirectory is $true, the built module's ModuleBase would be: `output/MyModuleName/2.0.1/` .PARAMETER ProjectName The project name. Defaults to the BaseName of the module manifest it finds in either the folder 'source', 'src, or a folder with the same name as the module. .PARAMETER SourcePath The path to the source folder name. Defaults to the same path where the module manifest is found. .PARAMETER MarkdownCodeRegularExpression An array with regular expressions that will be used to remove markdown code from the schema mof property descriptions. The regular expressions must be written so that capture group 0 returns the full match and the capture group 1 returns the text that should be kept. For example the regular expression \`(.+?)\` will find `$true` which will be replaced to $true since that is what will be returned by capture group 1. .PARAMETER BuildInfo The build info object from ModuleBuilder. Defaults to an empty hashtable. .NOTES This is a build task that is primarily meant to be run by Invoke-Build but wrapped by the Sampler project's build.ps1 (https://github.com/gaelcolas/Sampler). #> param ( [Parameter()] [System.String] $ProjectPath = (property ProjectPath $BuildRoot), [Parameter()] [System.String] $OutputDirectory = (property OutputDirectory (Join-Path $BuildRoot 'output')), [Parameter()] [System.String] $BuiltModuleSubdirectory = (property BuiltModuleSubdirectory ''), [Parameter()] [System.Management.Automation.SwitchParameter] $VersionedOutputDirectory = (property VersionedOutputDirectory $true), [Parameter()] [System.String] $ProjectName = (property ProjectName $(Get-SamplerProjectName -BuildRoot $BuildRoot)), [Parameter()] [System.String] $SourcePath = (property SourcePath $(Get-SamplerSourcePath -BuildRoot $BuildRoot)), [Parameter()] [System.String] $MarkdownCodeRegularExpression = (property MarkdownCodeRegularExpression @()), [Parameter()] [System.Collections.Hashtable] $BuildInfo = (property BuildInfo @{ }) ) # Synopsis: This task generates conceptual help for DSC resources. task Generate_Conceptual_Help { $OutputDirectory = Get-SamplerAbsolutePath -Path $OutputDirectory -RelativeTo $BuildRoot "`tOutputDirectory = '$OutputDirectory'" $BuiltModuleSubdirectory = Get-SamplerAbsolutePath -Path $BuiltModuleSubdirectory -RelativeTo $OutputDirectory if ($VersionedOutputDirectory) { # VersionedOutputDirectory is not [bool]'' nor $false nor [bool]$null # Assume true, wherever it was set $VersionedOutputDirectory = $true } else { # VersionedOutputDirectory may be [bool]'' but we can't tell where it's # coming from, so assume the build info (Build.yaml) is right $VersionedOutputDirectory = $BuildInfo['VersionedOutputDirectory'] } $GetBuiltModuleManifestParams = @{ OutputDirectory = $OutputDirectory BuiltModuleSubdirectory = $BuiltModuleSubDirectory ModuleName = $ProjectName VersionedOutputDirectory = $VersionedOutputDirectory ErrorAction = 'Stop' } $builtModuleManifest = Get-SamplerBuiltModuleManifest @GetBuiltModuleManifestParams $builtModuleManifest = [string](Get-Item -Path $builtModuleManifest).FullName "`tBuilt Module Manifest = '$builtModuleManifest'" $builtModuleBase = Get-SamplerBuiltModuleBase @GetBuiltModuleManifestParams $builtModuleBase = [string](Get-Item -Path $builtModuleBase).FullName "`tBuilt Module Base = '$builtModuleBase'" $moduleVersion = Get-BuiltModuleVersion @GetBuiltModuleManifestParams $moduleVersionObject = Split-ModuleVersion -ModuleVersion $moduleVersion $moduleVersionFolder = $moduleVersionObject.Version $preReleaseTag = $moduleVersionObject.PreReleaseString "`tModule Version = '$ModuleVersion'" "`tModule Version Folder = '$moduleVersionFolder'" "`tPre-release Tag = '$preReleaseTag'" "`tProject Path = $ProjectPath" "`tProject Name = $ProjectName" "`tSource Path = $SourcePath" "`tBuilt Module Base = $builtModuleBase" $configParameterName = 'MarkdownCodeRegularExpression' if (-not (Get-Variable -Name $configParameterName -ValueOnly -ErrorAction 'SilentlyContinue')) { # Variable is not set in context, try to use value from $BuildInfo. $configParameterValue = $BuildInfo.'DscResource.DocGenerator'.Generate_Conceptual_Help.$configParameterName <# Always set the value.
