public class VergilApplication
extends MoMLApplication

An application for editing ptolemy models visually.

The exact facilities that are available are determined by an optional command line argument that names a directory in ptolemy/configs that contains a configuration.xml file. For example, if we call vergil -ptiny, then we will use ptolemy/configs/ptiny/configuration.xml and ptolemy/configs/ptiny/intro.htm. The default configuration is ptolemy/configs/full/configuration.xml, which is loaded before any other command-line arguments are processed.

This application also takes an optional command line argument pair -configuration configurationFile.xml that names a configuration to be read. For example,

 $PTII/bin/vergil -configuration ptolemy/configs/ptiny/configuration.xml
 

and

 $PTII/bin/vergil -ptiny
 

are equivalent

If there are no command-line arguments at all, then the configuration file is augmented by the MoML file ptolemy/configs/full/welcomeWindow.xml

Note that if the configuration starts with "ptiny", then RemoveNonPtinyClasses is used to remove classes such as code generators that might be present in the model but are not part of the Ptiny configuration.

Constructor Detail

VergilApplication

public VergilApplication(java.lang.String[] args)
                  throws java.lang.Exception

Parse the specified command-line arguments, creating models and frames to interact with them. Look for configurations in "ptolemy/configs"

Parameters:

args - The command-line arguments.

Throws:

java.lang.Exception - If command line arguments have problems.

VergilApplication

public VergilApplication(java.lang.String basePath,
                         java.lang.String[] args)
                  throws java.lang.Exception

Parse the specified command-line arguments, creating models and frames to interact with them.

Parameters:

basePath - The basePath to look for configurations in, usually "ptolemy/configs", but other tools might have other configurations in other directories

args - The command-line arguments.

Throws:

java.lang.Exception - If command line arguments have problems.

Method Detail

errorAndExit

public static void errorAndExit(java.lang.String message,
                                java.lang.String[] args,
                                java.lang.Throwable throwable)

Print out an error message and stack trace on stderr and then display a dialog box. This method is used as a fail safe in case there are problems with the configuration We use a Throwable here instead of an Exception because we might get an Error or and Exception. For example, if we are using JNI, then we might get a java.lang.UnsatisfiedLinkError, which is an Error, not and Exception.

Parameters:

message - The message to be displayed

args - The arguments to be displayed

throwable - The Throwable that caused the problem.

main

public static void main(java.lang.String[] args)

Create a new instance of this application, passing it the command-line arguments.

Parameters:

args - The command-line arguments.

openLibrary

@Deprecated
public static void openLibrary(Configuration configuration,
                                           java.io.File file)
                                    throws java.lang.Exception

Deprecated. Use UserActorLibrary.openLibrary(Configuration, File)

Open the MoML file at the given location as a new library in the actor library for this application. An alternate class can be used to build the library if reading the MoML is not desired. The class must extend ptolemy.moml.LibraryBuilder and the _alternateLibraryBuilder property must be set with the 'value' set to the class that extends LibraryBuilder.

Parameters:

configuration - The configuration where we look for the actor library.

file - The MoML file to open.

Throws:

java.lang.Exception - If there is a problem opening the configuration, opening the MoML file, or opening the MoML file as a new library.

_createDefaultConfiguration

protected Configuration _createDefaultConfiguration()
                                             throws java.lang.Exception

Return a default Configuration. The initial default configuration is the MoML file full/configuration.xml under the _basePath directory, which is usually ptolemy/configs. using different command line arguments can change the value Usually, we also open the user library, which is located in the directory returned by StringUtilities.preferencesDirectory() If the configuration contains a top level Parameter named _hideUserLibrary, then we do not open the user library.

Overrides:

_createDefaultConfiguration in class ConfigurationApplication

Returns:

A default configuration.

Throws:

java.lang.Exception - If the configuration cannot be opened.

_createEmptyConfiguration

protected Configuration _createEmptyConfiguration()
                                           throws java.lang.Exception

Return a default Configuration to use when there are no command-line arguments. If the configuration contains a parameter _applicationBlankPtolemyEffigyAtStartup then we create an empty up an empty PtolemyEffigy.

Overrides:

_createEmptyConfiguration in class ConfigurationApplication

Returns:

A configuration for when there no command-line arguments.

Throws:

java.lang.Exception - If the configuration cannot be opened.

_parseArgs

protected void _parseArgs(java.lang.String[] args)
                   throws java.lang.Exception

Parse the command-line arguments.

Overrides:

_parseArgs in class ConfigurationApplication

Parameters:

args - The command-line arguments to be parsed.

Throws:

java.lang.Exception - If an argument is not understood or triggers an error.

_usage

protected java.lang.String _usage()

Return a string summarizing the command-line arguments.

Overrides:

_usage in class ConfigurationApplication

Returns:

A usage string.
