SciCoDE project

Creating a simple project in sciCoDE

In this section we will create the Hello World project in sciCoDE. As implementation language we are going to use java.

Creating the project

1. Inside Eclipse select the menu item File > New > Project.... to open the New Project wizard
2. Select sciCoDE Project then click Next to start the Open the new sciCoDE project wizard New Java Project wizard:
   • On this page, type "HelloWorld" in the Project name field, and then click Finish.

3. In the Package Explorer view, expand the HelloWorld project. The project is structured as followed:
   • src : contains the main "sci"-file, which stores the state of the workbench and a sidl file with the SIDL description of the components.
   • components : contains the java or c++ sources of the components in this project
   • includes : contains dependent SIDL files
   • import : a folder where scicode stores the files of imported components

Writing the SIDL description

The next step is to define the Hello World components. The application will consist of three parts:

• a user interface, which will be used to enter the user name
• a kernel, which will merge the user name with the "hello world" string
• a visualization, which will print the whole string on the console.

In this example this three parts are converted to components. The main idea is to pass the string entered in the first component(UI) to the kernel. The kernel will compute the new value of the string and forward it to the visualization. The only thing what we need to implement this scenario is a simple interface to pass strings between components. Our workbench setup should look like this: File:Hello world.png

Compiling the SIDL description

After creating SIDL description we need to compile it with the build-in SIDL-Compiler. Initially the compiler is not turned on. To do this select Project->Properties and then the sciCoDE compiler option to see the configuration setup.
