<# .SYNOPSIS Retrieves information about a project by reading data from a project.json file in ModuleTools project folder. .DESCRIPTION The Get-MTProjectInfo function retrieves information about a project by reading data from a project.json file located in the current directory. Ensure you navigate to a module directory which has project.json in root directory. Most variables are already defined in output of this command which can be used in pester tests and other configs. .PARAMETER None This function does not accept any parameters. .EXAMPLE Get-MTProjectInfo Retrieves project information from the project.json file in the current directory. Useful for debuggin and writing pester tests. .OUTPUTS hastable with all project data. #> function Get-MTProjectInfo { $Out = @{} $ProjectRoot = Get-Location | Convert-Path $Out['ProjecJSON'] = Join-Path -Path $ProjectRoot -ChildPath 'project.json' if (-not (Test-Path $Out.ProjecJSON)) { Write-Error 'Not a Project folder, project.json not found' -ErrorAction Stop } ## Metadata, Import all json data $jsonData = Get-Content -Path $Out.ProjecJSON | ConvertFrom-Json -AsHashtable foreach ($key in $jsonData.Keys) { $Out[$key] = $jsonData[$key] } $ProjectName = $Out.ProjectName ## Folders $Out['ProjectRoot'] = $ProjectRoot $Out['PublicDir'] = [System.IO.Path]::Join($ProjectRoot, 'src', 'public') $Out['PrivateDir'] = [System.IO.Path]::Join($ProjectRoot, 'src', 'private') $Out['OutputDir'] = [System.IO.Path]::Join($ProjectRoot, 'dist') $Out['OutputModuleDir'] = [System.IO.Path]::Join($Out.OutputDir, $ProjectName) $Out['ModuleFilePSM1'] = [System.IO.Path]::Join($Out.OutputModuleDir, "$ProjectName.psm1") $Out['ManifestFilePSD1'] = [System.IO.Path]::Join($Out.OutputModuleDir, "$ProjectName.psd1") return $Out } <# .SYNOPSIS Invokes the process to build a module in ModuleTools format. .DESCRIPTION This function is used to build a module, dist folder is cleaned up and whole module is build from scracth. copies all necessary resource files. .PARAMETER None This function does not accept any parameters. .EXAMPLE Invoke-MTBuild Invokes the process to build a module. #> function Invoke-MTBuild { [CmdletBinding()] param ( ) $ErrorActionPreference = 'Stop' Reset-ProjectDist Build-Module Build-Manifest Copy-ProjectResource } <# .SYNOPSIS Runs Pester tests for using settings from project.json .DESCRIPTION This function runs Pester tests using the specified configuration and settings in project.json.

Use this to quikcly setup a ModuleTools compatible module. .PARAMETER Path Path where module will be created. Provide root folder path, module folder will be created as subdirectory. Path should be valid. .EXAMPLE New-MTModule -Path c:\work # Creates module inside c:\work folder .NOTES The structure of the ModuleTools module is meticulously designed according to PowerShell best practices for module development.
