Mold.psm1

<#
.SYNOPSIS
   Gets Mold templates from various sources.

.DESCRIPTION
   This function retrieves Mold templates from different locations, including the local Template directory, path defined in environment variable MOLD_TEMPLATES, and templates from installed modules. It can filter templates by name or path, and optionally recurse through subdirectories. The function returns an array of objects representing the found templates.

.PARAMETER Name
   The name of the Mold template to search for. Search by name, supports tab completion

.PARAMETER TemplatePath
   The path to a directory containing Mold templates.

.PARAMETER Recurse
   If specified, the function will search for templates recursively in provide path.

.PARAMETER IncludeInstalledModules
   If specified, the function will also search for templates in installed modules. (Not yet implemented)

.EXAMPLE
Get-MoldTemplate

Retrieves the Mold template from Mold Module samples, Templates in path defined in env varible MOLD_TEMPLATES

.EXAMPLE
   Get-MoldTemplate -Name 'MyTemplate'

   Retrieves the Mold template named 'MyTemplate' from any of the available sources.

.EXAMPLE
   Get-MoldTemplate -TemplatePath 'C:\Templates' -Recurse

   Retrieves all Mold templates found in the 'C:\Templates' directory and its subdirectories.

.NOTES
   The function prioritizes templates found by name.
   The function searches for templates in the following locations:
     - The templates shipped along with MOLD module
     - Directories specified in the 'MOLD_TEMPLATES' environment variable.
     - Potentially installed modules (not yet implemented).
   The function returns an array of objects with properties like 'Name', 'ManifestFile', and 'TemplatePath'.

.SYNOPSIS
   Creates a new project or file from a Mold template.

.DESCRIPTION
   This function creates a new project or file based on a Mold template. It can either use a template from a specified path or retrieve a template by name. The function then interactively gathers input from the user, substitutes placeholders in the template files, and optionally executes a script to further customize the generated output.

.PARAMETER TemplatePath
   The path to the Mold template directory.

.PARAMETER Name
   The name of the Mold template to use.

.PARAMETER DestinationPath
   The path where the generated project or file will be created. Defaults to the current working directory.

.PARAMETER AnswerFile
   The path to an answer file containing pre-filled responses to template questions. Use New-MoldAnswerFile to generate the answer file skeleton for a given template.

.EXAMPLE
   Invoke-Mold -TemplatePath 'C:\Templates\MyProject'

   .EXAMPLE
   Invoke-Mold -TemplatePath 'C:\Templates\MyProject' -AnswerFile GoldProject.json

   Creates a new project based on the template located at 'C:\Templates\MyProject'. The user will be prompted for input to customize the project.

.EXAMPLE
   Invoke-Mold -Name 'WebTemplate'

   Creates a new project based on the Mold template named 'WebTemplate'. The template will be retrieved from a central location.

.NOTES
   This function requires the 'MoldManifest.json' file to be present in the template directory.
   The function supports placeholder substitution in template files using the format '<% MOLD_{Type}_{Key} %>'.
   The function can optionally execute a 'MOLD_SCRIPT.ps1' file to further customize the generated output.

.SYNOPSIS
    Creates an answer file for a Mold template.

.DESCRIPTION
    This function generates a JSON file (`Mold_Answer_File.json`) in the specified directory to be used as an answer file for a Mold template. Answer File can be fed to "Invoke-Mold" to provide answer as JSON content and skip interactive questions. Useful during automations or non-console execution of Mold templates.

.PARAMETER TemplatePath
    The path to the Mold template directory. This parameter is mandatory when using the 'TemplatePath' parameter set.

.PARAMETER Name
    The name of the Mold template. This parameter is mandatory when using the 'Name' parameter set.

.PARAMETER OutputDirectory
    The path to the directory where the answer file will be created. Defaults to the current working directory.

.PARAMETER Force
    If specified, the function will overwrite an existing answer file without prompting.

.EXAMPLE
    New-MoldAnswerFile -TemplatePath 'C:\Templates\MyProject' -OutputDirectory 'C:\Answers'

    Creates the answer file 'Mold_Answer_File.json' in the 'C:\Answers' directory based on the template in 'C:\Templates\MyProject'.

.EXAMPLE
    New-MoldAnswerFile -Name 'MyTemplate'

    Creates the answer file 'Mold_Answer_File.json' in the current working directory based on the template named 'MyTemplate'.

.NOTES
    The function retrieves the template either by path or by name.
    It reads the template's manifest file ('MoldManifest.json') to determine the questions and their types.
    It generates an answer file with placeholders for user responses, including question details like caption, description, and available options. Fill the answer file manually before feeding it to Invoke-Mold command.
    The generated answer file can be used to automate the input process when invoking the Mold template.

.SYNOPSIS
   Updates a MoldManifest.json file based on changes in a content of template directory.

.DESCRIPTION
   This function updates an existing MoldManifest.json file to reflect changes made to the corresponding Mold template project directory. It first validates the template directory and reads the existing manifest. Then, it compares the placeholders found in the template files with the parameters defined in the manifest. If it finds new placeholders, it adds them to the manifest. If it finds placeholders that are no longer present in the template, it removes them from the manifest. If it finds placeholders whose types have changed, it updates their types in the manifest. Finally, it writes the updated manifest back to the MoldManifest.json file.

.PARAMETER TemplatePath
   The path to the Mold template directory.

.EXAMPLE
   Update-MoldManifest -TemplatePath 'C:\Templates\MyProject'

   Updates the MoldManifest.json file in the 'C:\Templates\MyProject' directory based on any changes made to the template files.

.NOTES
   This function requires the 'MoldManifest.json' file to be present in the template directory. It only updates existing template MoldManifest.json file.
