Requirements and Opening

OpenPonk is a portable desktop application for Windows (7+), Linux and Mac based on Pharo platform. 32bit versions of any OS are not supported. Opening instructions and compatibility info is specified in README.txt file in the downloadable zip archive.

Once launched, clicking on the inner desktop will show a menu containing entries for OpenPonk. The same options are available on top bar on large enough displays.

Direct installation

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

Metacello new
     baseline: 'OpenPonkPlugins';
     repository: 'github://openponk/plugins';
     load: 'all'

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: 'OpenPonkPlugins';
     repository: 'github://openponk/plugins:v3.x';
     load: 'all'

Master branch and version 3 of OpenPonk supports Pharo 9 only. To download OpenPonk on Pharo 7 or 8, use OpenPonk version 2. Pharo 10 is not supported, but latest version or master branch might work.
Pharo 6 and below is not supported and OpenPonk version 1 and below cannot be loaded anymore.
