dip encourages the development of applications based on reusable components. This applies both to the development of new components so that they can be reused in the future in a different context, and to the reuse of existing components that were developed independently of dip.
Developers can choose to use the different parts of dip as required. Unlike many frameworks dip does not require its wholesale adoption to develop an application. dip makes it easy to take an existing application and refactor it gradually to make use of dip’s features. Developers can also choose to replace different parts of dip with their own implementations. The Architecture section describes this in more detail.
The dip API is fairly stable but will not be finalized until v1.0. dip should not be considered for production applications until v1.0 is released. The Roadmap section provides details of the planned development.
The current version of dip has the following features:
Like PyQt, dip is available under two licenses: the GPL (both v2 and v3), and the Riverbank Commercial License. Dual licensing is based on the principle of quid pro quo - something for something.
If you, your company or your organisation derive commercial benefit from Riverbank’s products and do not wish to distribute your complete source code you are required to purchase the appropriate number of commercial licenses.
Alternatively, if you are willing to follow the terms of the GPL, Riverbank software is available to you under Open Source licenses which allows you to develop, modify and distribute your software freely. If you wish to use an open source version of Riverbank’s products, you must contribute all your source code to the open source community, according to the terms of the applicable open source license.
By offering both open source and commercial licenses, Riverbank ensures the availability of resources for ongoing development and improvement of its products. By purchasing commercial licenses, you are no longer obligated to publish your source code.
dip is provided as a source packages created by Python’s distutils module. After unpacking the .tar.gz or .zip file run following command:
