GSoD 2020 Project Ideas
HPX's existing documentation can be found here. While it's already quite extensive, it has grown organically and is in need of restructuring and heavy editing. We recently moved our documentation to Sphinx for better navigation, but the content remained mostly unchanged. One problem is that the documentation contains a lot of information, which means that beginners can often struggle to find what they're looking for. At the same time, we don't want more advanced users to feel like they can't find what they're looking for.
The HPX documentation is written using reStructuredText and rendered using Sphinx. Familiarity with these is helpful, but not required as reStructuredText is easy to pick up. In addition, since most of HPX is implemented in C++, at least a basic level of familiarity with C++ will be helpful in understanding code examples and concepts explained in the documentation.

Abstract: HPX is largely modeled on existing or proposed C++ standard library functionality. While it's often enough to point users to standard library documentation (e.g. cppreference) as the HPX implementations usually follow the standard, it makes for a less than ideal experience for users as they have to jump between two different sites to learn about the HPX APIs. In some cases the HPX APIs extend the standard facilities and the standard documentation is not sufficient for users. This project aims to document such functionality within HPX for easier access for users. Examples of such un- or underdocumented features are
future,async,tuple,optional,any. Presenting our API documentation in a better way can be combined with this project. - Deliverable: New and/or corrected documentation for facilities corresponding to standard facilities.

- Abstract: As part of the move to Sphinx as a documentation system, the quality of presentation of our API documentation was reduced. As we're also planning a new major release of HPX and intend to specify the public API a more curated presentation of the API may be a better experience for users. This project aims to take our current API documentation and present it in a more user-friendly way, either through the existing tools (Doxygen and Sphinx), through Sphinx extensions (Breathe), or tools completely outside of Sphinx (standalone Doxygen). The current API documentation is presented here in a largely unstructured way.
- Deliverable: Restructured API documentation.

- Abstract: There are several HPX tutorials (e.g. HPX Workshop at HLRS - 2019) that implement example applications that are useful beginners. Some of these examples (e.g. Fibonacci, 1D Stencil) are included in the HPX documentation, some are not. The objective of this project is to add these tutorials to the HPX documentation.
- Deliverable: New tutorials in HPX documentation based on existing code and other presentation material

- Abstract: We always appreciate volunteer contributions to HPX but think that the process could be made easier to encourage new contributors. Our contributor's guide should be as straightforward as possible and contain the necessary steps for a new contributor to go from building to testing and submitting a pull request. Currently there exists only minimal information in the "Developer documentation" section of our documentation. In addition, there is scattered information for contributor's in this wiki.
- Deliverable: A new contributor's guide in our documentation that consolidates the existing information in the documentation and this wiki, as well as expands it if needed with missing information.
