<#
.SYNOPSIS This is a build task that generates markdown for a modules public commands. .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 $true, the built module's ModuleBase would be: `output/MyModuleName/2.0.1/` .PARAMETER ProjectName The project name. Defaults to the empty string. .PARAMETER SourcePath The path to the source folder name. Defaults to the empty string. The task does not use this parameter, see the notes below. .PARAMETER DocOutputFolder The path to the where the markdown documentation is written. Defaults to the folder `./output/WikiContent`. .PARAMETER HelpCultureInfo Specifies the culture that documentation is generated for. Defaults to 'en-US'. .PARAMETER DependentTypePath Specifies an array of paths to .cs files that will be loaded with `Add-Type` prior to generating the markdown (to be able to load types that is used by command parameters). Defaults to an empty array. .PARAMETER DependentModule Specifies an array of module names that will be imported (to be able to load types that is used by command parameters). Defaults to an empty array. .PARAMETER WithModulePage Specifies if a module page is created in the output folder. Defaults to `$false`. .PARAMETER AlphabeticParamOrder Specifies if parameters are ordered alphabetically. See the PlatyPS command help for exceptions. Defaults to `$true`. .PARAMETER ExcludeDontShow Specifies that parameters with `[Parameter(DontShow)]` will be ignored. Defaults to `$true`. .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). Parameter SourcePath is intentionally added to the task even if it is not used, otherwise the tests fails. Most likely because the script Set-SamplerTaskVariable expects the variable to always be available. #> [System.Diagnostics.CodeAnalysis.SuppressMessageAttribute('DscResource.AnalyzerRules/Measure-ParameterBlockParameterAttribute', '', Justification='For boolean values when using (property $true $false) fails in conversion between string and boolean when environment variable is used if set as advanced parameter ([Parameter()])')] 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 ''), [Parameter()] [System.String] $SourcePath = (property SourcePath ''), [Parameter()] [System.String] $DocOutputFolder = (property DocOutputFolder 'WikiContent'), [Parameter()] [System.Globalization.CultureInfo] $HelpCultureInfo = (property HelpCultureInfo 'en-US'), [Parameter()] [System.String[]] $DependentTypePath = (property DependentType @()), [Parameter()] [System.String[]] $DependentModule = (property DependentModule @()), $WithModulePage = (property WithModulePage $false), $AlphabeticParamOrder = (property AlphabeticParamOrder $true), $ExcludeDontShow = (property ExcludeDontShow $true), # cSpell:ignore Dont [Parameter()] [System.Collections.Hashtable] $BuildInfo = (property BuildInfo @{ }) ) # Synopsis: Generate markdown documentation for the public commands from the built module.
