In that second case, how to cleanly dispose of a blocked

Thanks!
I tried using a separate thread for reading the process'
stdout. It works, except that sometimes the output is shuffled
out of order.
Is there anything buggy in this:
__gshared string output;
void readBlocking(){
while ((c = fgetc(filepointer)) = 0)
output~=cast(char) c;
//NOTE: i can use something more efficient here but that's
beside the question
}
thread = new Thread( readBlocking);
output=null;
while(true){
Thread.sleep(...);
if(condition) break;
}
//now output is shuffled out of order sometimes
Furthermore, is there a standard way to tell when a process is
waiting for stdin input ? (cf condition above). Currently I'm
checking whether 'output' was modified within a timeout period
T, but that's fragile and incurs of penalty of T at least.

Re: Handling different types gracefully
On Monday, 1 July 2013 at 12:03:25 UTC, Roderick Gibson wrote: I'm asking because I'm doing some game development in D and I've come upon the entity component architecture, and it looks like a good way to handle the complexity and interdependency that games seem to have. The components wind up being plain old data types (I currently use structs), with systems that actually modify and interact with them on a per-entity basis. The basic idea is that you compose entities (basically just an id) with various components to give the specific functionality you need for that particular game object. The whole entity system is just a database for the different subsystems to query for entities (just an id) which have components that fulfill their criteria (for example a physics subsystem might only be interested in entities with the components position, movement, and collision, while a render subsystem might only be interested in entities with components position, mesh, sprite). There's also the reverse where the subsystems register which components they are looking for and then the entity system serves up entities that match the criteria. The standard way to store components is just to subclass them from a base class Component and then store a pointer to them in a Component[] in an overall entity manager. But then you have to do things like type casting the pointers when you return the queries, which seems a bit rough. It also feels wrong to make them inherit a class for the SOLE reason of getting around the type system. Anyway, I think I'm just rubber ducking a bit here, but I'm wondering if there's another way to do this, if someone has any experience with this sort of system. As an example of what I'm looking for, say there is a class Entities, with some type of container that could hold arrays of different component types (this is the part that really stumps me). I'd like to be able to do something like: ... auto entities = new Entities(); auto entity_id = entities.createEntity(); entities.addComponent!(position)(entity_id, pos); entities.addComponent!(movement)(entity_id, mov); entities.addComponent!(collision)(entity_id, col); auto physics_data = entities.getEntitiesWithComponents!(position, movement, collision)(); The two big requirements are some kind of regular, queryable structure to hold the components (of different types), and the ability to filter by type. Is anything like that remotely possible? Waiting for multiple alias this ?? And opDispatch to respond to unimplemented components.

void main () {
foo ( [ 1, 2, 3 ] ) ;
}
On both DMD 2.062 and 2.063 this compiles OK but causes a
segfault.
I'm running Kubuntu Raring 64-bit. Any hints?
Works for me ubuntu 64.
Do you have both versions installed?
Would it compile if you used the wrong druntime / phobos
libraries?

Also, I want to implement a random access range interface for it. That went pretty well, until I tried to sort it. Sorting function asserted Failed to sort range of type Array!(int). I've spent quite some time trying to figure out what's going on with no success. The implementation can be found at: https://gist.github.com/snosov1/5662471 I used DMD64 D Compiler v2.062 and LDC - the LLVM D compiler (trunk): based on DMD v2.062 and LLVM 3.2svn on Ubuntu. Phobos version was the one that came with the dmd compiler. Does anyone have any ideas what's wrong with the code I've provided? sort!(ab, SwapStrategy.stable)(arr); This worked for me with the code at your link. Of course it does not answer your real question. But it is a place to start looking. (assuming you aren't miles ahead of me already.)
