This chapter outlines the supported language constructs for the transformation of legacy software components.
Fabasoft app.ducx allows you to create a Fabasoft app.ducx project from an existing software component. To do so, click “Import“ on the context menu in Eclipse Project Explorer. Select “Existing Component as Fabasoft app.ducx Project” and click “Next“.
This will take you to the dialog box depicted in the following figure where you can select the source for creating the new Fabasoft app.ducx project. You may either select a container object (.coo) file from the file system or a software component from your development domain. Enter a Project name and the reference of your new software component in the Component field, and click “Next“ to proceed.
The remaining steps of the wizard are similar to the steps when creating a new Fabasoft app.ducx project from scratch.
After completing the remaining steps, the wizard creates a Fabasoft app.ducx project based on the software component you selected as source, and transforms the component objects belonging to the software component into domain specific language source code.
Note: A full transformation of all elements of the software component used as source might not be possible.
