But sometimes you just don\u0027t have the time or patience to set\nup everything correctly and just want a quick way to inspect some values at runtime.\n\nThis projects provides a [single header file](dbg.h) with a `dbg(\u2026)`\nmacro that can be used in all circumstances where you would typically write\n`printf(\"\u2026\", \u2026)` or `std::cout \u003c\u003c \u2026`. But it comes with a few extras.\n\n## Examples\n\n``` c++\n#include \u003cdbg.h\u003e\n#include \u003ccstdint\u003e\n#include \u003cvector\u003e\n\n// You can use \"dbg(..)\" in expressions:\nint32_t factorial(int32_t n) {\n  if (dbg(n \u003c= 1)) {\n    return dbg(1);\n  } else {\n    return dbg(n * factorial(n - 1));\n  }\n}\n\nint32_t main() {\n  std::string message = \"hello\";\n  dbg(message);  // [example.cpp:15 (main)] message = \"hello\" (std::string)\n\n  const int32_t a = 2;\n  const int32_t b = dbg(3 * a) + 1;  // [example.cpp:18 (main)] 3 * a = 6 (int32_t)\n\n  std::vector\u003cint32_t\u003e numbers{b, 13, 42};\n  dbg(numbers);  // [example.cpp:21 (main)] numbers = {7, 13, 42} (std::vector\u003cint32_t\u003e)\n\n  dbg(\"this line is executed\");  // [example.cpp:23 (main)] this line is executed\n\n  factorial(4);\n\n  return 0;\n}\n```\n\nThe code above produces this output ([try it yourself](https://repl.it/@sharkdp/dbg-macro-demo)):\n\n![dbg(\u2026) macro output](https://i.imgur.com/NVTzGRk.png)\n\n## Features\n\n * Easy to read, colorized output (colors auto-disable when the output is not an interactive terminal)\n * Prints file name, line number, function name and the original expression\n * Adds type information for the printed-out value\n * Specialized pretty-printers for containers, pointers, string literals, enums, `std::optional`, etc.\n * Can be used ins",
