The script player-piano-script.groovy
supports the playback of MagicDraw instructions to the Open API to update models according the instructions generated by the ingrid
tool.
If you come across an unsupported metatype or attribute, please add the necessary definition to the switch cases in the player-piano-script.groovy
.
switch(new_meta) {
case 'Class':
new_element = ele_factory.createClassInstance();
temp_ids[item_to_edit] = new_element.getID();
temp_elements[item_to_edit] = new_element;
new_element.setName(new_name);
homeless_elements.add(new_element);
break;
.
.
.
case "New Metatype":
new_element = ele_factory.create__Metatype__Instance(); // This is a MagicDraw API call
temp_ids[item_to_edit] = new_element.getID();
temp_elements[item_to_edit] = new_element;
new_element.setName(new_name);
homeless_elements.add(new_element);
...
The player piano takes the basic commands created by the ingrid code (e.g., create, replace, rename elements and attributes) and makes them compatible with the Cameo OpenAPI. A similar script could be written for any other modeling tool.
- With MagicDraw open locate the Tools menu
- Select
Tools > Macros > Organize Macros
- For the
Name
,Macro Language
, andFile
fields input "Player Piano", select "Groovy", and browse the file explorer (opened by clicking on the three dots button) to the.../Rapid Modeling Tools/player-piano/player-piano-script.groovy
groovy script. - Images included below
Once the macro is loaded, there will be a Tools > Macros > Player Piano
menu item. Use this to launch the macro.
The script is written in Groovy, and can be activated in MagicDraw through the Macro Engine. See MagicDraw Online Documentation for instructions on how to do this.
The Player Piano macro in Cameo Systems Modeler 2021xR2 produces an error:
MagicDraw cannot execute the Groovy macro, please make sure that the C:\Users\test_user\rapid-modeling-tools-master\player-piano\player-piano-script.groovy is correct. startup failed: C:\Users\test_user\rapid-modeling-tools-master\player-piano\player-piano-script.groovy: 142: unable to resolve class JsonSlurper @ line 142, column 18. jsonSlurper = new JsonSlurper(); ^ 1 error org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: C:\Users\test_user\rapid-modeling-tools-master\player-piano\player-piano-script.groovy: 142: unable to resolve class JsonSlurper @ line 142, column 18. jsonSlurper = new JsonSlurper(); ^ 1 error
The root issue is that Cameo 2021xR2 ships with the core
Groovy 3.0.7 JAR module that since
version 2
does not include JSON utilities. (Both Cameo versions 2021xR1 and 190sp4 ship with the Groovy 2.4.15 all
JAR that contains everything.)
Therefore, we need to update the plugin that executes Groovy scripts to explicitly import the JSON module.
- Go to the root of your Cameo 2021xR2 installation.
You should see a
plugins
folder. - Download the
groovy-json-3.0.7.jar
to
plugins\com.nomagic.magicdraw.automaton\lib\engines\groovy-3.0.7\lib
- Open the plugin configuration in a text editor:
You should see a
plugins\com.nomagic.magicdraw.automaton\plugin.xml
<library>
XML element importing the core Groovy 3.0.7 JAR:<library name="lib/engines/groovy-3.0.7/lib/groovy-3.0.7.jar"/>
- Add this line to
plugin.xml
just below the core Groovy import:This points the plugin to the module you downloaded.<library name="lib/engines/groovy-3.0.7/lib/groovy-json-3.0.7.jar"/>
- Run Cameo 2021xR2 and execute the player piano macro. You should see a "Select Package" window appear without errors.
