D runtime doesn't include any compilation abilities, it's not a Lisp. You'll need to invoke the compiler as a separate process. Look at this example: http://dlang.org/phobos/std_process.html#.execute
Re: Compiling D inside of a D program
I still hope they make DMD available as shared/static library just like tinyc compiler!

Hi, I was also interested in this topic. My research suggests that there is no easy or safe way to do this at the moment, as thedeemon suggests. Although I think it's worth offering a possible alternative: using a scripting language binding like LuaD[1], DerelictLua[2], or pyd[3]. From here, you can expose some functions/variables between them, and solve a lot of the same problems. That being said, I think it would be useful to have something like JavaCompiler[4]. It's not an optimal solution, but combined with a minimal compiler package it could help a lot. As far as I know, you need to ask permission to distribute DMD with your application, so it may be safer to include GDC or LDC if you want to go this route. Or ask Walter, of course.

To the best of my knowledge it's totally ok to have your program download the latest zip from dlang.org on the client machine and use that.

Sounds good to me, I more or less know what to do now, I'll be using DMD because of it's fast code compilation which is going to be KEY especially to multiplayer games, I would have LIKED to use GDC, but like I said, fast compilation times. (Or perhaps someone has an idea there..?)

Fast enough to where the engine is not spending 5 minutes compiling a heavily scripted (multiplayer usually) game, perhaps gdc -0fast would do it?

For a scripting layer, dmd is probably the best choice. If the scripts get really big you might still run in to some problems. If they remain small (or at least the bit that neds recompiling is small) then gdc/ldc would still be viable.
