CodeSnippet: Easier handling of ax::Vec2 on logs as example for other complex structures too

[aismann]

How to use:
Copy/Paste this code snipppet into your own source (e.g. MainScene.cpp)
You can also adapt it for any other complex structures too.

#include <fmt/core.h> #include "axmol.h" // or wherever ax::Vec2 is defined if you don't want use "axmol.h" // Custom formatter for ax::Vec2 template <> struct fmt::formatter<ax::Vec2> { constexpr auto parse(format_parse_context& ctx) { return ctx.begin(); // No custom format specifiers } template <typename FormatContext> auto format(const ax::Vec2& v, FormatContext& ctx) { return fmt::format_to(ctx.out(), "Vec2(x: {}, y: {})", v.x, v.y); } }; 

Using (example):

 ax::Vec2 myPos(42.0f, 17.5f); AXLOGD("myPos: {}", myPos); 

Output:
myPos: Vec2(x: 42, y: 17.5)
