Google Code-in Ideas 2017

This is the brainstorm page for the Google Code-In contest for 2017. As such, some or many of these may not end up being in our final released list of tasks that end up in Google Code-In. If you are a student, DO NOT start working on these ahead of time as they are ALL subject to change.

Our aim for this year will be to help bring Haiku closer to a Beta 1 release. This will be a good chance for you to see your work end up in a released product! We hope to have a large number of fun tasks this year. Whether this is your first time learning about Haiku, or your second or third time competing in the Code-In, we will have tasks suited to a variety of skill levels.

For Haiku Users and Developers, this is your chance to suggest some task ideas that students would be able to complete in about 2-4 hours of work time spread out over a few days. You can suggest bigger tasks, but they should be ones such that they could be broken down into smaller parts that fit this 2-4 hour timeline.

General Information

Google has announced that they are going to hold Google Code-In 2017 as disclosed in this blog post.

If you are interested in submitting an idea for a task then you can make one by posting on this topic in our forum.

For students interested in participating in Google Code-In 2017 be sure to read through Google's Getting Started Guide.

1. Code: Tasks related to writing or refactoring code

For coding tasks students should make sure to follow Haiku's coding guidelines.

1.2 Develop a web app, a plugin or fix a issue related to Haiku's web infrastructure

Example task Example Skills Example link
XFix a bug in our web app that records hardware compatibility Codebase on Github
Fix a bug in our documentation translation tool tickets on trac
Fix a bug in our copy of Pootle tickets on trac

1.3 Refactor, clean up or improve Haiku code

Example task Example Skills Example link
Fix a issue in Mail Wiki page on Mail
XFinish the network VirtIO driver for Haiku C++ Ticket on subject
Implement a console/serial VirtIO driver for Haiku C++
Add missing devices to our ice1712 driverC++ Ticket on subject

1.4 Fix a broken recipe in haikuports

Many recipes on Haikuports need to be updated to the current format. We are working on bots to autobuild all of these, but there is a lot of work that needs to be done in order for those to work smoothly. This is one place we could use much help, as it is one of the big blockers to the upcoming Beta1 release.

1.5 Fix bug listed in Haiku's Trac

Lots of open issues, we will post tasks for specific open Haiku issues.

1.6 Fix bugs or add features to the various Haiku Apps hosted at Haiku Archives
150+ Haiku applications, many with open bug reports you can try fixing. Here are some examples:

Applications with 4 or more open issues
Application Open Issues List
Weather (written by past GCI students)
Critial Mass

1.7 Fix issues reported by Coverity and other code checking tools

1.8 Write recipes for HaikuPorter

Try building other open source apps on Haiku and write a recipe to allow HaikuPorter to build it.

Add new port targets here

Investigate whether any of the following can be ported to Haiku - Chapel, OpenCV, Open Detection, Octave, Tor, Tiled, MariaDB, Inkscape, TensorFlow, Celestia

1.9 Add scripting interfaces to applications to make it more useful

Scripting is used in Haiku to interact programmatically with applications,like with the hey CLI tool. All apps already support basic scripting through the App Kit, but some would benefit from more specific scripting interfaces.

Applications that needs specific scripting interfaces
Example app Example need
XMagnify Make Magnify controllable by scripting, like zoom factor, and other actions.
XMediaPlayer Expose the current track as a scripting object, possibly reusing SoundPlay's interface.

1.10 Add accessibility features to applications to make them more useful to disabled people

Haiku already has some applications that could be useful for accessibility, but aren't really tailored with it in mind. The idea is to make them more useful in this context.

Applications that needs accessibility features
Example app Example need
XMagnify Make Magnify follow caret when mouse is not moving. Make Magnify "dockable" to the screen bottom or top.
