C++ Format Alternatives

Reviews and mentions

• Should I use C++ over C even if I wont use OOP

  Here is link number 1 - Previous text "fmt"

  Sometimes this means tossing out bad implementations like STD/STL C++ and using performant replacements like Google's Absiel containers, fmt, etc.

• [Belay the C++] Yet another reason to not use printf (or write C code in general)
  reddit.com/r/cpp | 2021-08-31

  Compile times are actually comparable to printf's + header included: https://github.com/fmtlib/fmt#compile-time-and-code-bloat. With modules the latter which is a fixed per-TU cost will go away and even now is likely included transitively anyway.

  Just use https://github.com/fmtlib/fmt It's a no brained. Faster, safer mare ergonomic

• Communicating that a float is rounded in debugging prints
  reddit.com/r/cpp | 2021-08-12

  In fixed format floating-point point numbers are nearly always rounded. The usual solution for avoiding data loss is using the shortest decimal representation. This is for example the default format in the {fmt} formatting library (https://github.com/fmtlib/fmt).

• How do I make my github project straight out of github buildable (no library dependecy errors,no library manager bullshit)?
  reddit.com/r/cpp_questions | 2021-08-08

  Currently I went to the library i wanted to use: https://github.com/fmtlib/fmt

• CMake 3.21.0 available for download - Announcements
  reddit.com/r/cpp | 2021-07-21

  If you want to look at a highly non-trivial example, I suggest to study fmt. I've made it a dual-mode library, i.e. it can be used as a traditional library or alternatively as a named module.

• Why is there still such poor compiler support for C++ Modules?
  reddit.com/r/cpp | 2021-07-14

  If you find something which does not work in modules please, please, please report it to your compiler vendor. I have personally been trying to knock out as many feedback bugs against MSVC as I can for each release and the compiler has been getting noticeably better for it. If you have a project which uses modules and is blocked somehow, send me a github link and I can build it and tease compiler bugs out. One great success story here is how we worked with /u/Daniela-E to get fmtlib built as a module interface: https://github.com/fmtlib/fmt/pull/2240.

• 8-bit computer emulator

  As for libraries you may find interesting/useful, spdlog and fmt are becoming extremely popular (the latter was even partially adopted into C++20). I use them in pretty much every project these days. Catch2 or doctest if you have any interest in adding unit testing.

• How can I get started with game/graphics programming using C++ and no engine?
  reddit.com/r/gamedev | 2021-06-07

  Understanding C also makes it FAR easier to reason about the run-time cost of code since you don't have potentially implicit information such as vtables, hidden this pointer dereferences, RTTI, dynamic casts, etc. C++ also performs like shit if you use the standard iostreams, hashing, etc. unless you use 3rd party replacements. Learning C first will lead to healthy skepticism instead of just blindly trust bloated, over-engineered libraries like Boost.

• std::source_location
  reddit.com/r/cpp | 2021-06-01

  And maybe add a reference implementation to https://github.com/fmtlib/fmt/

• Qtile users question on configuration.
  reddit.com/r/linuxquestions | 2021-05-30

  you mean this fmt? http://docs.qtile.org/en/latest/_modules/libqtile/widget/mpd2widget.html?highlight=fmt might be a better example of fmt at use than CapsNumLockIndicator

• Visual Studio 2019 version 16.10 Release
  reddit.com/r/cpp | 2021-05-26

  It has already been fixed in the master branch (https://github.com/fmtlib/fmt/issues/2295), you'll need to update your version of {fmt}.

• First release of dragonbox, a fast float-to-string conversion algorithm, is available
  reddit.com/r/cpp | 2021-05-22

  There are some benchmarks in https://github.com/jk-jeon/dragonbox#performance. TL;DR it's faster than other state of the art algorithms like Ryu, Schubfach and variations of Grisu. We saw a nice speed up when switching from Grisu3 to Dragonbox in {fmt}: https://github.com/fmtlib/fmt/pull/1882 and it has been improved even more since then.

• What can C++ do that Rust can’t? (2021 edition)
  reddit.com/r/rust | 2021-05-08

  Yes, mentioned in the features here: https://github.com/fmtlib/fmt
