If you have not already downloaded this program and installed it then, first follow the procedure on this page.
Creating a New SPAD Project
The following allows us to initiate a new SPAD project and populate it with files from the FriCAS project.
From the Eclipse menu select: File -> New -> Other
This brings up the wizard on the right. Select
Click on 'Next'
(If SPAD options don't show then check that the jar files are in the plugins folder as explained on this page.)
Enter the Project Name
Assuming that you want to populate the project with fricas SPAD files then, click on the lower 'browse' button and select the location of the FriCAS source. That is the directory that holds all the FriCAS source code (assuming you downloaded the FriCAS source as explained on this page.)
You can then click on finish (If you click on Next instead there are additional options but its best to leave these on their default values for now)
There may be some delay while the files are being processed.
The wizard dialog should then close and the project should then appear, in the 'package explorer' window, with src and src-gen folders.
There should be a folder for each FriCAS 'pamphlet' file. This contains a .txt file for the documentation and a number of .spad files.
The first time you doubleclick on an spad file, to open it, you may get this message about adding the Xtext nature, if so, click on yes.
The spad file is displayed, note that braces have been automatically added and macros have been applied (and their definitions commented out).
Errors are shown by a red underline. Note there are elements of the syntax that are not yet parsed correctly, such as a function name of '0'.
There is also an outline window, here elements of the structure can be selected and the corresponding code is shown in the main window.
