Hello,


Google Summer of code 2013 is accepting applications. Just like in the past years, we need a few mentors to ensure a successful event.

This year we plan to get significantly better organized and make sure the event is successful in measurable ways (finalized projects or committed contributions to dmd/druntime/phobos etc). We have made a mistake in the past of approving the GC project by Antti-Ville Tuuainen who subsequently became unreachable to follow through with merging his project in the mainline. We don't want to repeat such mistakes in the future, which means a closer, stronger mentor/mentee relationship.

So please reply to this or email Walter and myself if you have the time and inclination to mentor a student this summer. For a detailed mentor's manual, peruse http://en.flossmanuals.net/GSoCMentoring/.


Thanks,

Andrei

Count me in! I really enjoyed last years edition and I'd definitely be up for doing it again this year. Although I would be willing to work with anybody that has a good idea, I think Mr. Bothe has an interesting idea for this years work. Compiling D to CIL would be a huge boon to Mono-D as it would make real-time CTFE evaluation a reality. Or at least get us on the right path. We'll have to hammer out what can actually be done in three months.

Sounds great. Should I put you under flyboynw at gmail?

The reason why CTFE real-time evaluation hasn't happened yet, isn't related to that. It's not particularly hard to do JIT it. You probably imagine that the CTFE engine is given a syntax tree which has been semantically analyzed, and just has to compile it and run it. Just like a backend. Unfortunately, that's not the case.

The problem is rather that the interface between compiler and CTFE is very, very messy. So the challenge is knowing what to JIT. Basically, in the compiler, the evil lies in a file called optimize.c which is sort-of part of CTFE, and sort-of not, and has very complicated behaviour.

For example:
static int k = [1,2,3] [  $ - 2 +  { return $-2; }() ];

The delegate literal gets evaluated in CTFE. But, $ exists _outside_ the delegate literal.
There were literally more than a hundred of these corner cases. I've been working on them for well over a year, I'm close to getting them all.
Until this is done, attempting to compile CTFE code would be an exercise in frustration. You'll get it to work in 95% of cases, and then fail miserably with the rest.
Right now, this project is a trap.
