Installation Notes In order to install the Fables IME, just unzip the downloaded archive, and make sure the fables executable has the correct rights (755), so it can be executed. Please note the Fables IME will not work properly with non-Sun or non-IBM JVMs. Try installing one of these, and make sure Fables uses this JVM by specifying it with the -vm flag: fables -vm /full/path/to/java/bin/java Other Notes Please note that this release version of Fables does not contain the up-to-date documentation. It will be available soon. Features //--- FablesIME_2009_04_06 ----------------------------------------------
- Compiler:
- Minor bugfixes, performance enhancements
//--- FablesIME_2009_03_30 ----------------------------------------------
- Datasource Editor:
- %agent.xxx%, %model.xxx% variables can be used in the Datasource Editor
to refer to specified members (variables or constants) of the model ro
an agent instance.
- These references are validated during datasource creation.
- Fables IME:
- Verbose mode for Type Errors can be separately set for compilations.
- Several minor bugfixes.
//--- FablesIME_2009_03_06 ----------------------------------------------
- Improved support for string:
- Operator = can be used to compare strings lexicographily.
e.g. "a" < "b" == true
"a" <= "ab" == true
"aaa" >= "a" == true
etc.
- Function discreteUniform() has been extended and now can be used
to return a simple character (as a string) from a string.
e.g. discreteUniform( "abc" ) // result may be "a", "b" or "c"
- Function weightedSelection() has been extended and now can be used
to return a simple character (as a string) from a string.
e.g. weightedSelection( "ab", [ 0.8, 0.2 ] ) // returns "a" with the probability of 80%, "b" otherwise
- Function contains() has been extended and now can be used on strings
or string collections to determine if the specified first parameter
string contains the second one.
e.g. contains( "aaaXaaa", "aXa" ) == true
contains( [ "aaa", "bbb", "ccc" ], "ccc" ) == true
- Local constants are no longer final definitions (their values can be
modified within the scope of the function).
e.g. f() = [ set( a, 0, "x" ),
printLn( a ) ] // prints out "x"
where ( a = "a" ) ;
- MassGUI:
- The default layout of the charts can be reseted with the
"Charts --> Reset Chart Layout" menu item.
- Several bugfixes (including the OutOfMemoryError caused by reaching
the capacity of the Repast Console).
- Compiler:
- Several bugfixes (including the Type System).
//--- FablesIME_2008_12_12 ----------------------------------------------
- StdLib:
- readDoubleFromFile() is now capable of reading whitespace-separated
values from the input file (this modification doesn't breaks
reverse compatibility).
- Compiler:
- Some minor bugs were fixed related to equality checking. This
influences only the operator.
- Additional minor enhancements were performed regarding to
optimizations.
- Assignment and constructor generations might have ambiguous effects
on the simulation run. These issues have been solved.
- Major improvements have been performed on the Type System of the
compiler. These improvements are still under testing but can be
used in the current build of the software.
- PET:
- Minor issues has been solved since the last build.
//--- FablesIME_2008_12_01 ----------------------------------------------
- MassGUI:
- The positions of the displayed charts are now stored for each simulation, so it won't
require any more layouting by hand at every startup.
- A new menu item in the 'Charts' menu, that can be used to reset the perspective to the
default layout (** experimental feature **).
- Compiler:
- Minor bugs were solved regarding to the multi dimensional lists, sequences and integer to
double upcasts. The compiler should resolve these variables without problems. These
issues regarded both to the set() function and the := operator.
- There was a bug in the compiler that assigned a default value to a created agent's
variables even if it had an initial value. This bug was related to some optimization
issues.
- Minor optimization improvements regarding to multiple boolean inverse relations.
//--- FablesIME_2008_11_21 ----------------------------------------------
- Compiler:
- Multidimensional sequences are now working properly.
- Minor arithmetic problems were solved with the basic operators.
- Fixed some minor bugs with duplicate identifier lookups.
- Fixed generation of statement sets.
- Documents:
- Minor updates were performed in the Fables Tutorial.
//--- FablesIME_2008_10_27 ----------------------------------------------
- Charting Package:
- Minor bugs of the Datasource Editor script editor were fixed.
- IME:
- The total CPU usage of the IME was greatly reduced.
There was a bug that made the environment always busy at the
background, but the bug has been identified and eliminated.
- StdLib:
- Fixed minor type miscalculations with the '^' operator.
//--- FablesIME_2008_10_21 ----------------------------------------------
- Charting Package:
- Custom datasources created by the Datasource Editor can be edited and
deleted.
//--- FablesIME_2008_10_15 ----------------------------------------------
- Compiler:
- A minor bug was fixed that prevented the correct type evaluation of self recursive
functions.
- Improved duplicate identifier checking for classes.
- A bug was fixed that prevented using composite member selections, like:
var agent; ...
... a.func1( a.var, a.func2(a.const, a.func3()))
//--- FablesIME_2008_10_06 ----------------------------------------------
- IME:
- Automatic save for all of the edited source files before every compilation is performed.
- PET:
- New wizard for creating visualizations (applets) for PET simulations is added.
- PET actions now automatically creates and packs the required 'applet.jar' file into the
PET archive.
- Compiler:
- From now on, variables don't have to be declared before their first reference.
PoC:
startUp {
printLn(a) ;
printLn(b) ;
printLn(c) ;
};
var a = 10, b = false ;
var c = "S" ;
- StdLib:
- New function: exit().
Terminates the currently running simulation.
//--- FablesIME_2008_09_29 ----------------------------------------------
- Compiler:
- Some minor bugs/feature requests have been implemented for the set() function.
- From now on, multiple parameters can be declared at once.
PoC:
param a = 10, b = false; // New notation
param c = "S"; // Old notation
startUp {
printLn(a);
printLn(b);
printLn(c);
};
- IME:
- New wizard to import older Fables projects into the workspace.
- Fixed the console flushing problem that sometimes noted non-error results as errors.
- PET:
- Fables created visualizations are now enabled by default for the uploaded
simulations.
- Every agent field is now have a generated setter by default. Java coding and
descriptor editing is not necessary any more.
- Charting Package:
- User created statistic plugins can be integrated into the Datasource editor.
//--- FablesIME_2008_09_22 ----------------------------------------------
- IME:
- New actions in the Fables Editor's popup menu to comment and uncomment
blocks of selected code.
- Decreased the required JRE version to 1.5.
- Compiler:
- Clarified empty definition lists:
PoC:
model EmptyDefinitions {
startUp() {} ;
class EmptyClass {};
// At least one event definition is necessary [but it could be empty]
schedule {
1 : ;
};
} ;
- Charting Package:
- Histogram range setting bug fixed
- Multiple Histogram outliers bug fixed
- Simple values can be used in the Datasource Editor to create categories
- Node size in both Network Charts can be adjusted
- Chart data can be saved into CSV format in the context menu
- The Markers used for charts can be customized
