  • Replay a scenario with different parameters : automation by Samuel Dufour-Kowalski (2010/05/18 10:19)

    Capsis provides a new mechanism to replay scenarii with different initial or evolution parameters.
    This mechanism is called automation. This automation can be run in graphical model or in console mode.

  • Automatic user interface by Samuel Dufour-Kowalski (2010/01/18 15:19)

    Capsis is now able to generate automatically the graphical user interface for the model parameters
    without writing specific java code.

    Model parameters are displayed in a simple dialog box.
    The following type are supported :

    • Integer
    • Float/Double
    • String
    • Filename (String)
    • Enumeration
    • List
    • ...

    The generated dialog supports

    • Label translations.
    • Import/Export parameters from/to xml

    Documentation is available on the capsis website : http://capsis.cirad.fr/capsis/documentation/autoui

  • New model architecture by Samuel Dufour-Kowalski (2010/01/18 15:09)

    Since november 2009, Capsis supports a new model architecture. This new architecture intends to :

    • Reduce the number of necessary classes.
    • Simplify the implementation of the model
    • Support automatic graphical user interface
    • Support automation to replay a scenario and do some variation on the parameters

    The main differences with the previous architecture are:

    • Relay classes are optional : there is a default implementation
    • Settings and initial parameters are merged into a single class
    • Script mode is supported by default
    • Parameter classes and gui classes are separated

    Documentation is available on the capsis website : http://capsis.cirad.fr/capsis/documentation/model_architecture

  • Capsis Version 4.2.0 by Samuel Dufour-Kowalski (2009/11/02 18:13)

    The next major capsis release is 4.2.0. It will be available for download very soon.
    This new release includes important code change, but preserve a backward compatibility with all the models.
    These changes was necessary to prepare the future evolutions of Capsis.

    Capsis 4.2.0 main changes :
    • Kernel class renaming
    • Code refactoring (explicit import, dependencies, settings...)
    • Method provider : combine default implementations by simulating multiple inheritance
    • Script mode simplification
    • Groovy can be used to write scripts, tests and models
    • Model reorganization : relay classes are optional
    • Robust compilation : specific extensions are included in model directory (and not in capsis directory)
    • Other language than French and English are supported (Chinese...)
    • jib is replaced by ant
    • Automatic dialog generator
    • Geotools support
    • Task manager with cancelable tasks
    • Improved user doc manager (support offline documentation)
    • Improved installer (include or not java sources)
    • Javadoc on the web
    • Fix a lot of small bugs
  • More languages are supported in Capsis by Samuel Dufour-Kowalski (2009/09/29 14:26)

    Capsis now support other languages than French and English.

    Default system language is used by default.
    If a translation is not provided, Capsis will use the English language by default.

  • Capsis izpack installer available by Samuel Dufour-Kowalski (2009/09/29 14:24)

    Capsis can be packaged in a portable installer based on IzPack.
    Installer for capsis user based on the 4.1.8 version with open source models is available here

    To generate a particular installer, see : http://capsis.cirad.fr/capsis/documentation/packaging

  • SVN server fingerprint has changed by Samuel Dufour-Kowalski (2009/09/18 10:04)

    The SVN server has been relocated.
    If your SVN client (SmartSVN, Eclipse...) complains about a new fingerprint, you can accept the changes.
