Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FYI - The "SDL failed to get a vertex buffer for this Direct3D 9 rendering batch!" warning has been fixed with tcod version 16.1.1

Sharing Saturday #471
I'm currently writing another Python tutorial. I was hoping to have part-1 finished before this Sharing Saturday but it started while I'm still in the middle of updating the website. You can see the part-1 source I'm going with here and the resources I plan on using are organized here.

Is really Python3 so slow with libtcod?
See this NumPy/SciPy cave generator for a performant example.
-
Python libraries?
scipy.signal.convolve2d again, but used to count neighbors instead of masking them based on their direction. See this script for a cave generation example.

RoguelikeDev Does The Complete Roguelike Tutorial Starting June 28th 2022
The python-tcod repository is here. This is the full source of the Python port including all the C sources of libtcod which are included as a sub-module plus all the setup scripts invoked. Most source repos are linked from their PyPI package page.

Considering changing from libtcod to pygame for tiles…
I'll be asking you to install tcod from the sdl branch of its Git repository. I'd recommended cloning the repo but that isn't required. You just need to tell pip install where the experimental source is.

What does this OpenGL error mean?
This is a known issue. Libtcod will fallback to the SDL2 renderer and will then run correctly, so this error only notes that the OpenGL renderers failed to initialize but won't prevent libtcod programs from running.
-
Can anyone assist me with an issue installing tcod in Arch Linux?
I found old bugs with similar issues (breaking on some sdl dependencies) on https://github.com/libtcod/python-tcod and filed an issue.

C++ left arrow operator (2016)
Continuation passing monads form the basis of a perfectly valid and usable software architecture and programming pattern.
In the case of ostream and operator<<, this pattern reduces the number of intermediate objects that would otherwise be constructed.
If you object to iostream on religious or stylistic grounds, there's always fmt which is more like Go or Python string interpolation.[0]

Optimizing the unoptimizable: a journey to faster C++ compile times
Good catch, thanks! Fixed now. This explains why the difference was kinda low compared to another benchmark: https://github.com/fmtlib/fmt?tab=readme-ov-file#compile-tim....

Learn Modern C++
> This is from C++23, right?
std::println is, yes.
> I wonder how available this is within compilers
https://en.cppreference.com/w/cpp/compiler_support says clang, gcc, and msvc all support it, though I don't know how recent those versions are off the top of my head.
In my understanding, with this specific feature, if you want a polyfill for older compilers, or to use some more cutting-edge features that haven't been standardized yet, https://github.com/fmtlib/fmt is available to you.

For processing strings, streams in C++ can be slow
{fmt} has internal buffering but it's not yet exposed to users. There is a feature request for it: https://github.com/fmtlib/fmt/issues/2354. FILE buffering is not too bad but it can be easily optimized: https://www.zverovich.net/2020/08/04/optimal-file-buffer-siz....

adoption of fmt based logging
Automatic use of operator<< when that exists was present in fmt until version 9.0.0. In version 9 you could use FMT_DEPRECATED_OSTREAM to opt in the old behaviour, but this too was removed in version 10.0.0. Now there is no way to automatically use operator<<.

Codebases to read
Additionally, if you like low level stuff, check out libfmt (https://github.com/fmtlib/fmt) - not a big project, not difficult to understand. Or something like simdjson (https://github.com/simdjson/simdjson).
