Camera SVG rendered to PNG[^]
This is my current render of the final test document for my initial round of tests. It's got many complicated overlapping, semi-transparent gradients all xlink:href'd together.
It's not quite as fast as I'd like, because I traded away speed to dramatically reduce memory usage and increase flexibility, but it should be fast enough for small renders, which is what it's primarily meant for.
I still have more to do but it's basically just mop up at this point, with the largest task being to implement some baseline CSS support (selectors for classes and ids only so I don't need a DOM)
I'm thrilled.

I'm not going to lie, that's pretty damn impressive. Very nicely done.

Yes, I agree. Very impressive.

Thanks! I didn't design the image, but yeah, parsing and rendering it was not easy at first. It showed me a bunch of bugs I had in my code, so it was a godsend.

Working with an STM32 device and trying to implement program in c++. Every platform is a little different in the way it implements C++ so trying to learn the ins and outs on the STM32.
Been working on a simple Timer singleton class for the past 6 hours and it's been 2 steps forward and 1 back. Should be fairly easy but there were so many gotchas that made it very frustrating.

I'm probably old fashioned, but I don't find C++ that helpful when it comes to embedded work - stick to C and assembler is my preferred route.
The idea of embedded is to get the best performance out of limited resources (speed, memory and / or power) and the extra overhead of class based OOPs isn't necessarily a good idea. And it's way harder to keep an eye on memory management to ensure memory fragmentation doesn't rear its ugly head after 2 weeks of continual runtime ...

I disagree c++, I've used C++ on various platforms for years and never had a problem.
I find; code size comparable, speed acceptable (you can also mix c++ and assembler).
The Arduino platform uses c++ as it's major language and there are libraries for everything under the sun.

Forget classes. template and constexpr mean I can create faster/more efficient code in C++ than you can readily create in C.
You don't have to use features that generate overhead in C++. Zero overhead C++ is a thing.
Besides, Generic Programming > Object Oriented Programming anyway

Nah. template can be applied to functions as well as struct/class.
Warning - basic implementation details:
When your compiler sees a template instantiation it basically works like a mail merge for source code, but with typed inputs. It takes those inputs, and uses the template to determine what TEXTUAL output to produce. That C++ text output is then fed back to the compiler and fully parsed/compiled (some initial parsing is done on the preinstantiated template, but it's not fully processed by the compiler until instantiation).
That's the functionality of the template keyword. It's a source code generator.
Edit: I should add, with template you often create "throw away" types - they're never actually used at runtime, and the compiler generates no direct machine code output for them. I don't consider those to be actual structs/classes because they are never used. They are simply a way to cajole the compiler into doing things it wasn't designed for when C++ was dreamed up.

I am on the opposite side (at work): forced to use C while I would use C++ instead.
As others suggested C++ follows the Zero-overhead principle[^].

I use the C runtimes with C++ language features on embedded.
I avoid the STL and most of the C++ standard runtimes.
Why?
For the exact reasons you're running into - the C runtimes in general are far more consistent platform to platform.
Furthermore, The STL is not set up to use the heap responsibly on constrained systems. You will get heap frag and eventual crashes without creating your own custom allocators for everything.

Ditto
I ran into problems because of basic stupidity on my part and trying to do something that I hadn't done before.
Responsible memory/resource management is crucial in all embedded languages.
I generally don't do dynamic memory allocation, just instantiate classes once. When I do need to do dynamic memory allocation I attempt to allocate blocks that are the same size to reduce fragmentation. When I can't do that I am very cautious to destroy when done with.
You can shoot just as big a hole in your foot using C as C++!
