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 ([http://dlang.org/phobos/index.html Phobos]), working on its compilers ([[Compilers]]), bringing D to mobile devices, shaping GUI libraries for D, integrating D with other languages and more.

GDC is a D compiler based on the GCC backend.  There are a few outstanding issues in GDC that have ended up in the backlog of known issues to fix, as well as changes that could be beneficial to upstream and other compilers.
 +
 
 +
====Compiler Improvements====
 +
* Implement support for compiling with LTO (<code>-flto</code>) turned on.
 +
* There are various XBUG markers in GDC's testsuite, some haven't been looked at in a long time.  There should be fewer!
 +
* Internal Documentation.  Ideally every function should have a comment describing its use and input values.  As the bulk of what happens in the glue is just providing for backend members declared in the front-end.  Most should be pretty trivial to work through.
 +
* Debugging Support.  Enumerals of non-scalar types currently emit no debugging information.  A solution should be proposed and implemented for this.
 +
* Improving codegen for better optimisations.  Currently all shared types are marked volatile, which is a workaround for not being able to prevent shared decls from being cached into registers by other means.  Improvements could also be done around parameter passing, taking advantage of D storage attributes.
 +
 
 +
====Library Improvements====
 +
* Get shared library support working. The current implementation upstream in DM druntime has not been tested or merged in, and it is not clear what changes are required to support it, or whether is even going to be feasibly possible with GDC.
 +
* GDC EH support is lacking the ability to chain multiple thrown exceptions together in its deh personality routines.
 +
* Now GCC has __atomic primitives defined for the new C++ memory model.  We should take advance of these and update the API in gcc.atomics which hash out the old  __synchronise primitives.  The new __atomic primitives having a one-to-one mapping with core.atomic being just one of the benefits of this.
 +
* More targets are expected to land in GDC pretty soon.  In preparation for this, we should investigate an alternate layout of druntime before the long lists of version conditions becomes a problem for port maintainers (See [https://d.puremagic.com/issues/show_bug.cgi?id=11666 #11666]).

[http://code.google.com/p/ddt/ DDT] is an Eclipse-based IDE for the D programming lanaguage, aiming to support rich functionality, particularly semantic functionality (code completion, find definition, find references, etc.). There are two areas which prospective students could target for improvement:
 +
* DDT Core Engine
 +
** Make the DDT semantic engine available as a command-line daemon tool (similar to [https://github.com/Hackerpilot/DCD DCD]).
 +
** Add support for source formatting (with formatting options).
 +
** Add support for semantic search in the semantic engine (search symbols by anem and type).  For example, "where in my code is the function std.stdio.writeln" called?", or "which classes in my code subclass the given class?".
 +
** Improve semantic engine / code completion capabilities. For example, understand template instantiation, function overloads, etc.
 +
* Eclipse Specific Enhancements
 +
** Improve/add UI support for [http://code.dlang.org/about DUB] multiple build configurations and launch.
 +
** Reduce usage of [https://eclipse.org/dltk/ DLTK] code, possibly refactoring or rewriting DLTK functionality into an IDE-neutral layer (LangEclipseIDE).
 +
** Add support for continous build mode (build and report errors on the fly).
 +
 
 +
Some of these ideas are a bit small for a full GGoC project, so it might make sense to combine a couple of tasks into a single project.

This is a project focuses on bare metal cross-compilers and an appealing eco-system to surround it. The goal is to raise the awareness of D in the open hardware community at large and prove D's systems programming lanugage title along the way. It's hard not to notice the growing momentum of the open hardware movement. Yesterday's newbies awkwardly messing with theirs first [http://arduino.cc/ Arduinos] are today's  mature embedded systems hackers. The hanger for ever more powerful systems takes them en mass towards ARM development boards. These systems often lack a good open source toolchain, e.g. linker scripts, HAL, so that D certainly can be a compelling offering in this setting (compared to C/C++ in usability). The project is two-fold and can be geared towards any of the 2 major parts:
 +
* Getting a bare-metal D runtime support on Cortex-M3/M4 with as many language features as possible. A minor victory would be having a minimal thread-less and GC-less runtime. A more ambitious plan here is creating a small-ish RTOS in D, to provide full runtime with threads, mutexes etc.
 +
* Create a [http://wiring.org.co/reference/ Wiring] or [http://developer.mbed.org/ mbed] look-alike library in D for a selected family of popular chips (and consequently a range of boards). Instead of cloning a popular API you might also design your own hardware abstraction library using D to it's full extend. The challenge here is to tackle things like GPIOs, USARTs, I2C, SPIs, PWM, ADC and other peripherals commonly found in MCUs in a future-proof way.

This is the D Google Summer of Code page for 2015. To learn more about this year's event, see the Google Summer of Code 2015 page. If you are interested in participating in the 2015 GSOC as either a student or mentor, and want to do something related to D, please feel free to contact our GSOC administrator Craig Dillabaugh (firstname dot lastname at gmail dot com).


Timeline

The timeline for GSoC for 2015 has now been posted here.

Ideas

Plenty of challenging and important projects exist in the D world. 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.

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.

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

GDC Project - The GNU D Compiler

GDC is a D compiler based on the GCC backend. There are a few outstanding issues in GDC that have ended up in the backlog of known issues to fix, as well as changes that could be beneficial to upstream and other compilers.

Compiler Improvements

  • Implement support for compiling with LTO (-flto) turned on.
  • There are various XBUG markers in GDC's testsuite, some haven't been looked at in a long time. There should be fewer!
  • Internal Documentation. Ideally every function should have a comment describing its use and input values. As the bulk of what happens in the glue is just providing for backend members declared in the front-end. Most should be pretty trivial to work through.
  • Debugging Support. Enumerals of non-scalar types currently emit no debugging information. A solution should be proposed and implemented for this.
  • Improving codegen for better optimisations. Currently all shared types are marked volatile, which is a workaround for not being able to prevent shared decls from being cached into registers by other means. Improvements could also be done around parameter passing, taking advantage of D storage attributes.

Library Improvements

  • Get shared library support working. The current implementation upstream in DM druntime has not been tested or merged in, and it is not clear what changes are required to support it, or whether is even going to be feasibly possible with GDC.
  • GDC EH support is lacking the ability to chain multiple thrown exceptions together in its deh personality routines.
  • Now GCC has __atomic primitives defined for the new C++ memory model. We should take advance of these and update the API in gcc.atomics which hash out the old __synchronise primitives. The new __atomic primitives having a one-to-one mapping with core.atomic being just one of the benefits of this.
  • More targets are expected to land in GDC pretty soon. In preparation for this, we should investigate an alternate layout of druntime before the long lists of version conditions becomes a problem for port maintainers (See #11666).

Proposed Project Mentor: Iain Buclaw

DDT

DDT is an Eclipse-based IDE for the D programming lanaguage, aiming to support rich functionality, particularly semantic functionality (code completion, find definition, find references, etc.). There are two areas which prospective students could target for improvement:

  • DDT Core Engine
    • Make the DDT semantic engine available as a command-line daemon tool (similar to DCD).
    • Add support for source formatting (with formatting options).
    • Add support for semantic search in the semantic engine (search symbols by anem and type). For example, "where in my code is the function std.stdio.writeln" called?", or "which classes in my code subclass the given class?".
    • Improve semantic engine / code completion capabilities. For example, understand template instantiation, function overloads, etc.
  • Eclipse Specific Enhancements
    • Improve/add UI support for DUB multiple build configurations and launch.
    • Reduce usage of DLTK code, possibly refactoring or rewriting DLTK functionality into an IDE-neutral layer (LangEclipseIDE).
    • Add support for continous build mode (build and report errors on the fly).

Some of these ideas are a bit small for a full GGoC project, so it might make sense to combine a couple of tasks into a single project.

Bare Metal ARM Support

This is a project focuses on bare metal cross-compilers and an appealing eco-system to surround it. The goal is to raise the awareness of D in the open hardware community at large and prove D's systems programming lanugage title along the way. It's hard not to notice the growing momentum of the open hardware movement. Yesterday's newbies awkwardly messing with theirs first Arduinos are today's mature embedded systems hackers. The hanger for ever more powerful systems takes them en mass towards ARM development boards. These systems often lack a good open source toolchain, e.g. linker scripts, HAL, so that D certainly can be a compelling offering in this setting (compared to C/C++ in usability). The project is two-fold and can be geared towards any of the 2 major parts:

  • Getting a bare-metal D runtime support on Cortex-M3/M4 with as many language features as possible. A minor victory would be having a minimal thread-less and GC-less runtime. A more ambitious plan here is creating a small-ish RTOS in D, to provide full runtime with threads, mutexes etc.
  • Create a Wiring or mbed look-alike library in D for a selected family of popular chips (and consequently a range of boards). Instead of cloning a popular API you might also design your own hardware abstraction library using D to it's full extend. The challenge here is to tackle things like GPIOs, USARTs, I2C, SPIs, PWM, ADC and other peripherals commonly found in MCUs in a future-proof way.

Phobos: D Standard Library

There is still signficant work to be done in order to get the D Standard Libraries into a proper state. The following libraries are good candidates for GSoC projects:

  • std.benchmark: (Jens and Russell)
  • std.i18n: (Jens and Russell) Design and implement a basic internationalization framework. It may be possible to implement this with pragma(msg). For proof of concept see http://arsdnet.net/dcode/i18n.d . It should provide at least the following functionality:
    • A locale part, std.i18n.locale which should detect a user's default lanaguage, select a global application lanaguage, and provide types to describe and work with locales.
