The Script Designer or Scripting feature gives you the ability to extend and customise your apps with the functionalities and procedures you would rely on in your business activities.
The Script Designer lets you create, edit and manage your app's business logic from a bird's eye view. A typical script is built using a couple of predefined Actions and optionally a set of Variables. If needed, user-defined actions can be created in the Function Designer and then used in a script.
On the TIVITY platform the Script Designer is accessible at different locations. Refer to the article to learn more about the various options to add scripts in your app.
The Script Designer is divided into multiple areas.
Area Designation
Actions Menu
Script Area
Variables Menu
Each area provides different features and might have additional areas. Each section of the Script Designer is described in more details below.
The Actions Menu contains all available actions to create a script. Because of the large number actions are organised in groups based on their core functionality.
The return type of an action is displayed on the right-hand side of each entry.
When you click on an action is open the Action documentation area at the bottom. This shows you the details of the action like its description and purpose, the expected Parameters and the Return Type provided.
The Filter input field allows you to quickly access an action based on its name.
This area contains the actual statements and instructions of a script. It is the editor where actions are added to and where the functionality of the script can be configured.
The navigation bar of a script is located at the top of the Script area. There you can either expand or collapse all items in the active scope of the script, you can navigate between focused scopes, and switch between different view modes.
Validation is located at the bottom of the Script area. It provides information about the current state of a script, i.e. whether it contains severe Errors, Warnings, or general Info.
A variable can be added into the script via drag and drop.
Here, the Filter input field also allows you to quickly access a variable based on its name.
Depending on the selected view mode different features are available. The following matrix shows the details of each view mode.

The Simple view mode provides access to a reduced number of Actions and shows the Script area only. This view allows you to focus on the script content and might be a good choice for simple functionalities.
In Advanced view mode the platform provides you with all available Actions and Variables. While writing a sophisticated or complex script this view mode might offer best options to work efficiently.
Following section provides suggestions and good practices on how to organise and structure a script.
A script can be of different length or complexity and might appear confusing. There are numerous statements to assign values to variables, to process data from various data sources, and possibly interactions with other systems in regards to integration and interactions.
On first sight the above sample looks overloaded and confusing. Let's see how it would be possible to give a cleaner appearance and a better approach to organise a script.
A typical structure of a script would work with at least two scopes.
Definition of variables
Operations
This is related to the separation of concerns or any other kind of criteria to provide you with a better overview and focused areas of functionality.
Any available, built-in action with its parameters and return type is documented in the article.
The two buttons and on the left-hand side allow you to expand and collapse all script elements. The eye icon on the right-hand side lets you of the Script Designer.
When you click on Save the script is validated and any unresolved issues will be shown in the Validation area. More information about is described at the end of this article.
The Variables Menu provides access to all available variables. The number of variables varies depending on the calling context, i.e. or Function Designer, etc.
To change between Simple and Advanced view mode, click on the View Mode icon in the Script navigation bar and choose an option.
The Block action can be used to create groupings of multiple statements and to separate the script into logical scopes. Therefore it is common practice to split a script into multiple blocks of statements. Additionally, use the feature to give your block elements relatable names.
Using multiple block elements enables you to make use of the quick action. Narrow down the visible content of a script and only work on the most relevant parts at a certain time. This approach shall give you a better experience editing your scripts.
