Visualize the test coverage of Roassal3

Roassal3 is an agile visualization engine for Pharo 8 and Pharo 9. Roassal was created to enable interactive data visualization. Sister projects: Roassal3Documentation, Roassal3Exporters.

Roassal3 is free and open source, but backed by Object Profile. Commercial support offerings are available, including training and custom consultancy services. Check RoassalPro for more information.

Pharo Installations

Roassal3 is included in Pharo 9. This means that you do not need to install anything else. Pharo 9 contains Roassal 0.9.6b. Two installation flavors are available: stable and latest (a.k.a bleeding-edge).

Stable version

If you wish to install Roassal in Pharo 8, then execute the following code snippet in a Playground:

Metacello new
    baseline: 'Roassal3';
    repository: 'github://ObjectProfile/Roassal3:v0.9.9c';
    load.

Latest version

If you wish to have the lastest release of Roassal, then execute the following code snippet in a Playground:

Metacello new
    baseline: 'Roassal3';
    repository: 'github://ObjectProfile/Roassal3';
    load.

In order to suppress warnings you may prefer:

[Metacello new
    baseline: 'Roassal3';
    repository: 'github://ObjectProfile/Roassal3';
    load ] on: MCMergeOrLoadWarning do: [:warning | warning load ]

You can load the full version (including Mondrian and experimental packages) using:

[Metacello new
    baseline: 'Roassal3';
    repository: 'github://ObjectProfile/Roassal3';
    load: 'Full' ] on: MCMergeOrLoadWarning do: [:warning | warning load ]

A major effort on writing documentation is under way. The wiki pages are yet another source of documentation for Roassal3: https://github.com/ObjectProfile/Roassal3/wiki

Roassal3 as a dependent application

If you wish to set a dependency to Roassal3 in your application, you simply need to add the following in your baseline:

spec baseline: 'Roassal3' with: [ spec repository: 'github://ObjectProfile/Roassal3/src' ].

To depend on a full version of Roassal3, you may use:

baseline: 'Roassal3' with: [ spec repository: 'github://ObjectProfile/Roassal3/src'; loads: #('Full') ];
