This GUI is intended to help developers create a wrapper. Each CCP4i2 wrapper must have a DEF XML file which defines the input and output data and any control parameters. The main window will help create a DEF XML file. There are also options under the Tools
The first step is to create a wrapper directory using the Tools->Make wrapper plugin option. In the new window you must enter a unique name for the wrapper and choose whether it goes in the general wrappers or a particular pipeline directory. You have a choice of basic templates and of license to prepend to the template. You can add alternative licenses to the directory $CCP4I2/data/plugin_templates/license_templates.
Once the wrapper directory is created you should use the main defEd editor to create the DEF XML file. But, beware, if you are lucky there may already be COM template file for generating the input command file for the program that you which to run. If you want to use an existing COM template file then you must ensure that you parameter names are consistent with those used in the COM file. The DEF file should be saved with the path $CCP4I2/wrappers/myWrapper/script/myWrapper.def.xml.
The main functionality of this defEd editor is to create and edit DEF XML files for CCP4i2 GUI and pipelines. The editor is split vertically into three panes. The top pane shows the current contents tree, the middle pane is the object editor with tools to edit the currently selected item in the data definition and the bottom pane has help text. A right mouse click in any widget in the gui gives a menu with the option of help.
The current data contents tree is shown in the top pane along with buttons to..
Append container - a container is added at end of the 'top level' of the tree
Insert container - a container is inserted after current item at same level in the tree
Add object - add a data object in either the currently selected container or after the currently selected data object
Delete object - delete the currently selected container or data object
Click on any item in the tree to make it editable in the object editor.
You should start by appending a container and using the Name widget in the object editor to set a suitable name. The recommended def file structure (open for discussion) is to have three containers for inputData, outputData and controlParameters. The controlParameters could (should?) have sub-containers for the different components of a pipeline. Any additional parameters needed for gui function should be in a separate guiControls container.
When you add an object it is created with type CString. Use the table on the left side of the object editor to select the appropriate data class. A right mouse click on any item in this table will give documentation in the help pane. Also edit the Name for the data object. On the right side of the pane the appropriate qualifiers for each data class are shown. These enable simple customisations of the basic class so avoiding the need to write a Python subclass for trivial data.
The qualifiers are described in the class documentation but some general points:
The top line of the object editor enables defining a list or dictionary of the chosen data type. Note that, unlike Python list or dictionary a CList or CDict is of only one data type. A CListist has three qualifiers: listMinLength, listMaxLength and compare. Compare should be set to 1 or -1 to switch on validity checking that successive values in the list are ascending or descending in value. Note that the list item class must have a __cmp__() method.
The class to handle program input of MTZ columns, CProgramColumnGroup, is a special case for which the plugin developer can specify the contents of the class in the XML file. (It would be conceptually easier to insist on sub-classing!). The 'qualifiers' pane for this class includes a table in which you should enter the 'program' name of the column and the required column type. You can enter a comma-separated list of preferred column names, to be used by default if they appear in the MTZ file. The additional columns for Partner and Offset can probably be ignored.
The Save option on the File menu can be used to save the contents tree to an XML file. You will get an additional dialog box requiring the header information for the XML file.
Beware that defEd currently has no tools for Undo/Redo or moving data items. These are not an immediate priority (c.f. more data classes, command templates etc.) - please let me know if you find this a serious problem.
