A lot. In fact I previously wrote a small logger that uses <code>printf</code> called <a href="https://github.com/icyveins7/spfLogger">spfLogger</a>. I do enjoy the flexibility of tuning every single width/precision with a few characters, and it&rsquo;s something I haven&rsquo;t yet seen C++ be able to emulate with as little irritation.</p> <blockquote> <p>I haven&rsquo;t gotten around to writing code using newer <code>std::format</code> or <code>println</code> yet, so the jury&rsquo;s out on that.</p>https://icyveins7.github.io/posts/2024/09/who-knew-a-simple-logger-class-would-be-this-complicated/Mon, 09 Sep 2024 20:00:00 +0800https://icyveins7.github.io/posts/2024/09/who-knew-a-simple-logger-class-would-be-this-complicated/<blockquote> <p>Writing a printf-based C++ logger class was more of a journey than I originally thought..</p> </blockquote> <p>I recently had to work with a codebase where the build process was so convoluted it couldn’t be run and debugged from within a Visual Studio instance, <em>despite being a Visual Studio solution</em>.</p> <p>This was primarily because it had a bunch of Java components, which were mainly used for the UI, and that prevented it from being run as a standard C++ application within the debugger (or maybe you could? I couldn’t find a way..)</p>
