Haskell.org GSoC results for 2018
Posted on September 1, 2018 by Jasper Van der Jeugt (permalink)
Google Summer of Code 2018 is officially over. The Haskell.org organisation had a very productive year with 17 accepted projects out of which 15 were successful. We would like to thank the students and mentors for the great summer, and, of course, Google for its generous support towards the open source community.
Before we get into the summary of this year, we’d like to bring attention to the fact that we will soon start preparing for GSoC 2019. This means we will be looking for:
Project ideas: Even if you are not interested in participating yourself, maybe you have some ideas about what a student could hack on to improve the Haskell ecosystem. If that is the case, please submit a PR against this repo or just shoot us an email.
Mentors: If you are interested in mentoring a student throughout the summer, feel free to contact us. You do not need a specific project idea – anyone with some Haskell experience willing to help others is welcome.
Students: If you are thinking about applying to Haskell.org next year, it’s never too early to look for interesting projects.
Please reach out to us if you are interested in any of the above!
Visual Tools and Bindings for Debugging in Code World
Student: Krystal Maughan
Mentors: Chris Smith, Gabriel Gonzalez
This project was successful. Things got off to a slow start, but once Krystal got going, she tackled some projects with a lot of impact and benefits for users. You can find a good overview in her blogpost.
Student: Chitrak Raj Gupta
Mentors: Andrey Mokhov, Moritz Angermann
This project unfortunately did not pass the first evaluation.
Add support for deprecating exports
Mentors: Matthew Pickering, Erik de Castro Lopo
This project was successful. It looks like deprecated exports will be arriving in GHC 8.8 thanks to alanas’s efforts this summer. He wrote a blogpost about his experience as well.
Student: Simon Jakobi
Mentors: Herbert Valerio Riedel, Alex Biehl
This project was successful. An initial version of the
:doc command made it into GHC-8.6, and Simon made many improvements to the Haddock internals. You can read more about it in his blogpost.
Improving the GHC code generator
Student: Abhiroop Sarkar
Mentors: Carter Schonwald, Ben Gamari
This project was successful. Because of the complexity of the compiler work relative to this students familiarity, the code hasn’t been merged in yet and still needs a lot of cleanup and iterating. However, Abhiroop intends to continue working on this project with the Haskell and GHC community for the next few months. You can read Abhiroop’s summary here.
Crucible: A Library for In-Memory Data Analysis in Haskell
Student: Gagandeep Bhatia
Mentors: Marco Zocca, Andika D. Riyandi
This project was successful. Together with Gagandeep, we made some changes to the goals of this project initially and decided to have him target existing libraries rather than doing a greenfield project. He ended up making a number of good contributions to the Data Haskell ecosystem, and the Frames library in particular. He also wrote a wrap-up which you can read here.
Dependently Typed Core Replacement in GHC
Student: Ningning Xie
Mentors: Richard Eisenberg
This project was successful. Ningning writes:
It was an excellent experience for me to complete GSoC 2018 with Haskell.org. During these three monthes, I got the chance to dive into the state of the art compiler for Haskell programming language, GHC, with the help from my mentor and the broader community.
I chose the project because dependent types are one of my major research interests. And indeed I gained a lot from it. Firstly, the project was challenging, and working on such a huge codebase sounded frightening, but I managed to make progress and get lots of fun from it. I have learned a lot during this summer, which includes not only Haskell skills, but also many design principles inside GHC.
More details are available in her in-depth report.
Benchmarking graph libraries and optimising algebraic graphs
Student: Alexandre Moine
Mentors: Andrey Mokhov, Alois Cochard
This project was successful. Alexandre worked on a variety of tasks, including benchmarking, optimisations, testing and even correctness proofs. His blogpost has more details.
Improvements to GHC’s compilation for conditional constructs.
Student: Andreas Klebinger
Mentors: José Calderón, Joachim Breitner, Ben Gamari
This project was successful. Andreas posted this gist including some very impressive numbers. Some patches that he worked on this summer have already been merged into GHC, and it looks the bulk of his work will also be merged soon.
Support for Multiple Public Libraries in a .cabal package
Student: Francesco Gazzetta (@fgaz)
Mentors: Mikhail Glushenkov, Edward Yang
This project was successful. Francesco delivered great work just like last year and it sounds like this will be merged into the Cabal library soon. He put together a final report here.
Functional test framework for the Haskell IDE Engine and Language Server Protocol Library
Student: Luke Lau
Mentors: Alan Zimmerman
This project was successful. Luke wrote a bit about the project here. About his experience, he writes:
I had very little “real world” Haskell experience before starting, and there’s a lot of stuff they don’t teach you in university. But both my mentor and the Haskell community were extremely helpful with getting me up to speed and answering my many questions. Especially the #haskell channel on Freenode! In a lot of IRC channels you can find yourself asking question and never being answered, but the people at the Haskell channel were very eager to help and explain/discuss lots of different topics.
Student: Shayan Najd
Mentors: Ben Gamari, Alan Zimmerman
This project was successful. Shayan made significant progress to the trees-that-grow fork of GHC, and has a lot of patches ready to merged and reviewed. The mentors are very positive about the approach. Shayan’s summary can be found here.
Student: Wisnu Adi Nurcahyo
Mentors: Tom Sydney Kerckhove, Jasper Van der Jeugt
This project unfortunately did not pass the second evaluation.
Enhancing the Haskell Image Processing Library with State of the Art Algorithms
Mentors: Alp Mestanogullari
This project was successful. Khilan made several contributions to the Haskell Image Processing library. You can see some cool examples of the various algorithms in the his wrap-up blogpost.
Making GHC Tooling friendly
Student: Zubin Duggal
Mentors: Ben Gamari, Gershom Bazerman, Joachim Breitner
This project was successful. Zubin’s patches have not been merged yet but should be in the next few months. His final report can be found here.
Helping cabal new-build become just cabal build
Student: Alexis Williams
Mentors: Herbert Valerio Riedel, Mikhail Glushenkov
This project was successful. Alexis contributed key features to Cabal’s new-build infrastructure and also fixed an impressive amount of bugs. She writes about her experience here.
Parallel Automatic Differentiation
Student: Andrew Knapp
Mentors: Sacha Sokoloski, Trevor L. McDonell, Edward Kmett, Alois Cochard
This project was successful. Despite being an extremely hard topic to tackle, Anrew was able to get some impressive preliminary results. These lay out a very good foundation for future work that could be very valuable to the Haskell community.
We would like to thank all the participants again for the great summer and we already look forward to the next one!
