function Write-CUClassDiagram { <# .SYNOPSIS This script allows to document automatically existing script(s)/module(s) containing classes by generating the corresponding UML Diagram. .DESCRIPTION Automatically generate a UML diagram of scripts/Modules that contain powershell classes. .PARAMETER Path The path that contains the classes that need to be documented. The path parameter should point to either a .ps1, .psm1 file, or a directory containing either/both of those file types. .PARAMETER ExportFolder This optional parameter, allows to specifiy an alternative export folder. By default, the diagram is created in the same folder as the source file. .PARAMETER OutPutFormat Using the parameter OutputFormat, it is possible change the default output format (.png) to one of the following ones: 'jpg', 'png', 'gif', 'imap', 'cmapx', 'jp2', 'json', 'pdf', 'plain', 'dot' .PARAMETER OutPutType OutPutType is a Set of 2 variables: Combined, Unique Combined, all files present in a directory are drawn in the same graph. Unique, all files present in a directory are drawn in their own graph. .PARAMETER Show Open's the generated diagram immediatly .PARAMETER IgnoreCase By default, Class names MUST be case identical to have the Write-CUClassDiagram cmdlet generate the correct inheritence tree. When the switch -IgnoreCase is specified, All class names will be converted to 'Titlecase' to force the case, and ensure the inheritence is correctly drawed in the Class Diagram. .PARAMETER PassThru When specified, the raw Graph in GraphViz format will be returned back in String format. .PARAMETER Recurse Dynamic Parameter, available only if the Path Parameter is a Directory containing other directories. If the parameter is used, all subfolders will be parsed. .EXAMPLE #Generate a UML diagram of the classes located in MyClass.Ps1 # The diagram will be automatically created in the same folder as the file that contains the classes (C:\Classes).
