Direct installation

To install latest OpenPonk with all default plugins to an existing Pharo 7, 8 or 9 image, use the following snippet:

Metacello new
     baseline: 'OpenPonk';
     repository: 'github://openponk/openponk/repository';
     load: 'complete'

Just beware that this is the master branch and might be unstable.

For downloading specific version, add the version to the repository path. For example:

Metacello new
     baseline: 'OpenPonk';
     repository: 'github://openponk/openponk:2.x/repository';
     load: 'complete'


On most systems extracting the archive and launching the executable file should be sufficient (for example openponk-class-editor.exe on Windows and openponk-class-editor on Linux).

In case of errors, make sure you have write privileges to the extracted directory.

Once launched, clicking on the desktop will show a menu containing entries for OpenPonk.


  • Windows builds: Windows 7 or higher (64bit)

  • Linux builds: any recent 64bit distro except OpenSUSE and Fedora-like ones

  • Image-only builds use following Pharo image versions:

    • 2.x and latest: Pharo 8 64bit
    • 0.x and 1.x: Pharo 6.1 32bit

Versions 1.x and lower may require extra configuration on Linux. Please refer to Pharo’s official guide. Additionally you will require 32bit cairo2 library, usually available in distribution package managers as libcairo2:i386 (debian), libcairo2, etc.


Bug reports and feature requests:

To report a bug or request a feature related to implementation of specific kind of models/notations, use the related build repository. For general OpenPonk issues, use the OpenPonk core repository. If you are not sure whether is it related to the model/notation implementation or OpenPonk core itself, use the model/notation issue tracker and we will move the issue to its proper place.
