C++ is love

I needed some garbage-collector like advantages without the overhead so I wrote a 123 line file to give me exactly that. I love C++, and right now I don't know why I ever messed with .NET. :thumbsup::thumbsup::thumbsup: I'm usually not one to holy roll about technology but this language absolutely rules. The only downside with it is it hides nothing (and it doesn't parse properly**), but hiding nothing is just as big an advantage as a liability. Oh how I missed you, C++. ** C++ should really be parsed with a GLR parser so you don't have to worry about incomplete types being a thing.

It doesn't really do garbage collection as such. As an analogy imagine the garbage man came once a week and burned your house down. It's much more time and space efficient than taking out the trash. You can't actually delete objects in my scheme, only allocate to pools. You can recycle entire pools though, manually, freeing (invalidating) all pointers (or objects) therein. Doing it that way makes it fast fast fast and it works on constrained memory environments. Also it was easy to code.

When I saw your post, I wondered how badly you were going to get flamed, given the popularity of C# on this site. I never thought this thread would stay so civilized, let alone be fairly positive. :)

I don't hate C++, but I don't share your sentiments. This is almost certainly my own failing, though—it's not a problem with the language so much (which is alright, I guess), I just always end up fighting with the compiler/linker. I've never worked with C++ enough to become much more than minimally competent with it.

I gave it away under the MIT license. It was just a little bit of code anyway.

There's a certain point - and it can take awhile with C++ - where you reach a level that it is no longer intimidating or as frustrating. True, I did recently spend all morning and ask a stackoverflow question because I missed a "=0" at the end of one of my functions and was responded to with "missing vtable for class" or some such, but that's life, you know? :laugh:

I see you're using both
#pragma onceand#ifdef includeguards. Is that really necessary? GCC supports both, going back to at least version 4.8, so the #pragma doesn't even need to be wrapped in an #ifdef _MSC_VER. But maybe you know something I don't, or maybe you're using some other compiler that doesn't understand the #pragma? Also, picking nits, since I have nothing better to offer, I see that this is a memory pool for contrained memory environments. That must be a constrained, contained memory situation, correct? :)Keep Calm and Carry On

I used to put a test of the preprocessor in headers :
#pragma once
#ifdef HEADER_H
#error pragma once was ignored
#else
#define HEADER_H
#endifI have not used very many compilers but I never saw the error message. I use only VS now so I don't do that any more.

GCC throws a "#pragma once in main file" if I don't guard against them appearing. OTOH MSVC seems to like #pragma once to be in there for its source editors.

I could do that but I'd rather recover gracefully. What I did compiles with no warnings and that's my major concern.

I'm still kind of massaging the code. It's so simple it works as is and will probably remain basically the same, but I've tweaked little things like changed the template parameter from
CtoTCapacityI'm still not sure I like so I haven't recommitted yet but any changes will be minor.Real programmers use butterflies

Actually, it does. Time to move to Assembly.
Okay that's fair, except I can't think of much I can't get to in C++ with the right massaging of the compiler. I can manually build vtbls, i can make call stack frames myself, typically, I can even drop to inline assembly if I really want. So I see it more as giving you more tools than ASM. I don't think it takes anything away.

Back in the days of yore, when I did my C programming, I discovered alloca(). Used inside of functions, instead of malloc() (for example), it would free allocated memory when you left the function. I didn't look into the workings but I'd presume it used the stack for memory. Update: Quick Search [^] and it's in C++, too - and it does use the stack for allocatons.

One of the problems with stack allocation is on platforms like the ESP32 and most of the arduinos, they don't give you a lot of stack space. I know usually one grows up and the other grows down but I run out of stack declaring 2kB blocks sometimes so there might be some kind of artificial limit. That's why I usually use the heap for my pools.
