.SYNOPSIS Public function that set all script variables for a build task. This function should normally never be called by it's own, the function should only be called (as a function) by tests. .DESCRIPTION Public function that set all script variables for a build task. This function should normally never be called by it's own, the function should only be called (as a function) by tests. .PARAMETER AsNewBuild Tells the script to skip variables that need the finished built module to be able to be returned. For example, if this parameter is used it evaluates the ModuleVersion from GitVersion, instead from the built module's manifest. .NOTES Only the scriptblock portion of this function is used by the task by calling: . Set-SamplerTaskVariable This dot-sources the entire scriptblock of this function. This is done so that the variables are set in the task's scope, and so that the variables can be re-used throughout the tasks. To use the scriptblock the task can (must?) have the parameters (and its respective default value): - $ProjectName = (property ProjectName '') - $SourcePath = (property SourcePath '') - $OutputDirectory = (property OutputDirectory (Join-Path $BuildRoot 'output')) - $BuiltModuleSubdirectory = (property BuiltModuleSubdirectory '') - $ModuleVersion = (property ModuleVersion '') - $VersionedOutputDirectory = (property VersionedOutputDirectory $true) - $ReleaseNotesPath = (property ReleaseNotesPath (Join-Path $OutputDirectory 'ReleaseNotes.md')) - $BuildInfo = (property BuildInfo @{ }) TODO: The above should be in the README.md instead, or CONTRIBUTING.md. .OUTPUTS [System.String[]] See https://github.com/gaelcolas/Sampler#task-variables. .EXAMPLE . Set-SamplerTaskVariable -AsNewBuild Call the scriptblock set script variables. The parameter AsNewBuild tells the script to skip variables that need the finished built module. .EXAMPLE .
