ini-configA single-header library that converts INI-formatted string literals to a key-value pair list at compile-time.Requires C++20; tested on gcc 10.1 and clang trunk. Passes -Wall -Wextra -pedantic.FeaturesDirect accesses to values are compile-time evaluated, allowing an INI config to be used for project/program configuration.Values can be accessed as strings, integers, or floating-point numbers.Run-time support includes key lookup, iteration through the key-value list, and key existance checking; all of which can be filtered by section.Try it on Godbolt.INI format notesHandles single-line key=value pairs (extra whitespace is okay)Supports sectionsSupports comments (start line with ';' or '#')Supports wide stringsINI format is validated at compile-time, with future goal of clearly reporting syntax errorsHow to use```cppinclude "ini_config.hpp"// Simply place the _ini suffix at the end of your config string:constexpr auto config = R"(someflag = true[Cat]color = graylives = 9)"_ini;// Or, go for a more functional look://constexpr auto config = makeiniconfig;auto KVPcount = config.size();            // = 3for (auto kvp : config) {}                // Iterate through all KVPs                                          // (or use begin()/end())for (auto kvp : config.section("Cat")) {} // Iterate through all KVPs under [Cat] section                                          // (or use begin("Cat")/end("Cat"))config.get("someflag");                   // Searches entire config for "someflag", picks first match                                          // This call gets compile-time evaluated to "true"config.get("Cat", "lives");               // Searches "Cat" section, compile-time evaluated to "9"config.get("Cat", "lives");          // Compile-time evaluated to 9config.get("Dog", "lives");               // Does not exist, compile-time evaluated to ""config.contains("Dog", "lives");          // Compile-time evaluated to falseconfig.tryget(argv[2]);                   // Same interface and behavior as get(),                                          // use this when run-time evaluation is necessaryconfig.trycontains("color");              // Run-time evaluated to true```See the header file for further documentation.
