Jeliot 3.6.1 "The International release"

New features

  • Better support of UTF-8 character sets where special fonts are available. Go to Options and tick the "Save Files In Unicode" options.

New features

Bugs fixed

  • Improved array initializers handling.

Jeliot 3.5.2

New features

  • Printing
  • Ability to start a program with command line parameters, for public static void main(String[] args).
  • Java Web Start version of Jeliot officialy out

Bugs fixed

  • Some problems with object oriented features solved
  • Other bugs fixed

Jeliot 3.5.1

Enhacements:

  • Enhance run until with faster execution so that the animation duration will be changed to a very short time while running until a certain line.
  • History view improved, less resources usage.

Bugs fixed:

  • Correct interpretation of all this() method calls.
  • Fixed a couple of bugs in this and super method call handling.
  • Fixed a bug related to recursive toString calls.
  • Fixed a bug that related to recursive or otherwise combined method calls such as "method(method2());" which made the call tree visualization incorrect in some cases.
  • Other minor bugs.

Jeliot 3.5.0

New features:

  • 2 and 3 -dimensional arrays (no support for their array initializers).
  • Jeliot 3 interaction with BlueJ improved.
    • Projects now are better loaded, classes dependencies solved.
    • A constructor call is enough to start a visualization.
  • Inheritance calls are now animated in the right order. Support for this and super method calls.
  • Options move to a separate menu
    • Save on compilation: Set it on if you want to have your program automatically saved when pressing "Compile".
    • Ask for method: To start the animation with a method call different than the main method, click here. You will be prompted for a method everytime you press "Compile".
    • Pause on message: Jeliot will pause the animation every time an information message appears on the animation. Useful for presentations, when lecturer wants to explain in more detail why such message appeared.
    • Show history view: This option will enable the history view. Disabling it will make the animation to go faster.
    • Select font: Now you can select the font you want your code to show up.
  • Jeliot options can be modified through properties files in user's home directory (folder ./jeliot).
  • German is now added to the supported languages
  • History view now saves images into HD.
  • Replace '\t' characters with spaces when saving.
  • Maximized window when starting.

Fixed bugs:

  • Static variables handling is corrected.
  • Stepping in constructors is now possible.
  • Internal threads are handled correcly.

Jeliot 3.4.3

Fixed bugs:

  • Class main method was not always recognized.
  • Input methods not always detected.

Thanks to new VisCos students!

Jeliot 3.4.2

  • First international version of Jeliot 3. Menus and messages translated to Finnish, French, and Spanish. If you want Jeliot 3 translated into your language, contact us: Jeliot Team.
  • Now Jeliot benefits from the Java Web Start technology. Check it starting Java through our trial version here!! (Thanks ILIAS team!)
  • Static final variable bug corrected. (Thanks Linda!)
  • Corrected visualization of preincrement and postdecrement. (Thanks Des!)
  • Added buttons to handle the History view.
  • Improved Run Until feature. Now it is possible to stop run until with rewinding the animation or setting the run until line to zero.
  • Input should now have focus always.
  • Better loading resources to ease the embedment of Jeliot 3
  • Possibility to call other than main method at the beginning of the program. More useful when used with the BlueJ extension!!

Jeliot 3.4.0

  • Improved editor with Syntax Highlighting (thanks to JEdit).
  • Array Initializers, speed up.
  • Start Jeliot animation from any method in your class, useful if you don't have a main method.
  • History view, want to repeat the last part of the animation, use the History view.
  • Call Tree view, interested in how recursion works, have a look at the call tree view.
  • Logical operators && || now work in shortcircuit.
  • Improved object-oriented suppor, like Static Field Access.
  • Start Jeliot with a filename as a parameter like "jeliot If.java", it will look first in Examples.

Other new features

  • Support for CASE statements.
  • Run until, just indicate a line and the animation will fast-forward to it.
  • System.out.println and System.out.print support, for the shake of being "standard".
