Info

A new module can be created by specify a file in the format given in Figure 4-3. The users who are familiar with programming would like to create the new modules. But to write a specification file in a text editor is inconvenient for users because they have to know the format and then make sure there are no typos. In order to make it easy, a Module Editor (a module specification wizard) is developed for the users. (a) (c) Figure 4-4 The Module Editor - 32 - (b)
The Module Editor is a tool for creation or modification of a module specification. It provides a GUI to the users. This GUI will help the users fill information in right positions and then stores all the information in the format of a module specification file. Figure 4-4(a) shows the interface of this module editor. This interface contains four parts from the top to the bottom. The first part is used to show or fill in the name and the categories of this module. The second part is used to show the input parameters. The uses can modify an existing parameter by clicking the parameter. A window including the information of this parameter is shown (see Figure 4-4(b)). The users can also add new parameters and delete parameters. The third part is used to show the outputs. There is no output in this example. The fourth part is used to show and edit the source code. In the left side, there is a tree to show both the Tcl keywords and Culgi commands. And the right side is a text editor to edit the source code. This text editor imports some components from Python2.3 IDE. So it has the text editor features like coloring the keywords and auto indent. Figure 4-4(c) shows an module specification file generated by the Module Editor. 4.3 Module Library In Culgi-GPE, all modules’ specifications are stored in a folder named CMLib (Culgi Modules Library).In this folder, several subfolders exists. Each subfolder is a category. To tell the system this folder is a Culgi category, the folder name will be string “Culgi” plus the category name. For example, in CMLib, there is a folder named CulgiPalette, then in the Culgi GPE, there will be a category named Palette. Thus, a new category can be added simply by creating a new folder with name “Culgi***”. Files in the category folder are supposed to be modules. But not all files in the folder are the module specification files. For example, in each folder, there will be a file named syslib.def , which records all the modules in this folder; it is not a module file. Only a file with a name which begins with “Culgi” and ends with “.py” is a module. The scanning of all modules and all categories are done by the system. That is to say, when a user adds a new module file in the subfolders of CMLib, this module will appear in the Culgi GPE dynamically without user to restart the whole system. 4.4 Kernel The kernel in fact is a processor between interface and nodes. It receives commands from the Interface Part and does some relevant actions and passes the most detailed operation commands to the Module Part. The main functionalities are listed below: • Initialization: Load Tcl Interpreter and Culgi.dll into the system. These external software packages are used when executing the user’s program. • Scan the Module Library: Scan all subfolders in Folder CMLib, and the files in each subfolder. And then record the name of modules in File syslib.def of each subfolder. • Create a module instance: Create a module object according to the module name given by the - 33 -
