Ideas

Plenty of challenging and important projects exist in the D worlds. They range from writing new or improving existing modules of D's standard library (Phobos), working on its compilers (Compilers), bringing D to mobile devices, shaping GUI libraries for D, integrating D with other languages and more.

Idea #1: SDC Project - D Compiler as a Library

Project Desription:

The SDC project (https://github.com/deadalnix/SDC) is an effort to provide a D compiler as a library. Any ideas to further the development of this project are welcome, but for a student who would like a specific project we propose the following task(s):

• Start by implementing with @property feature of D. This feature will allow a D programmer to create functions that are called using the same syntax as variable access.
• Using the @property feature the student will be able to implement the runtime support for slices and associative arrays. The operations to implement are as follows:
  • Implement arrray operations like concatenation and appending, and implement a sound memory management strategy for the underlying data.
  • Implement a generic and efficient hash table. The data structure and algorithms used must be flexibile enough to be adapted to any type of data that might be stored in the table. A concurrent version of the table is need for shared data.
• Finally, the student will implement masquerading of D syntax into calls for the runtime.

To learn a little more about SDC we recommend you check out the following from D Conf 2014: http://dconf.org/2014/talks/sechet.html

Its Good To Know

• Please watch Amaury's DConf talk on SDC.
• SDC is developed in D (of course) so you will need to be proficient in D by the time you start coding.
• You should have taken at least one course on compilers, or at the least be willing to educate yourself in this regard. There is a decent course availabe through Coursera https://www.coursera.org/course/compilers
• You should familiarize yourself with classicial data structures for arrays and have knowledge of various schemes for table implementations, (it is worthwhile to read up on hopscotch and robin hood hashing).
• SDC uses LLVM for code generation, so some familiarity with LLVM will be required (see http://llvm.org/docs/tutorial/index.html).

Proposed Project Mentor: Amaury Sechet

Amaury, or Deadalinx as he is now in the D community is an Engineer with Facebook.

Tips for students

Daniel Pocock has written a detailed blog about initiatives students can take if they want to have a serious chance of being selected in GSoC 2015 without a focus on one specific organization.
