ini-config
A single-header library that converts INI-formatted string literals to a key-value pair list at compile-time.
Requires C++20. Tested to work on gcc 10.1 and clang trunk. Passes -Wall -Wextra -pedantic
.
Features
- Comments and whitespace removed during compilation
- Handles single-line
key=value
pairs with very basic syntax error reporting - Supports sections
- Supports comments (start line with ';' or '#', preceding whitespace is okay)
- Supports wide strings
How to use
#include "ini_config.hpp"
auto config = R"(
someflag = true
[Cat]
color = gray
lives = 9
)"_ini;
// Returns count of key-value pairs (KVPs), 3 in this case
config.size();
// Iterate through all KVPs
for (auto kvp : config) {}
// Iterate through all KVPs under [Cat] section
for (auto kvp : config.section("Cat")) {}
// Access specific values
config.get("someflag"); // Returns "true"
config.get("lives"); // Searches all KVPs, returns "9"
config["lives"]; // Same as above
config.get("Cat", "color"); // Only searches [Cat] section, Returns "gray"
config.get("Dog", "color"); // No match, returns ""
See the header file for further documentation.
How it works (brief)
_ini
prefix constructs anini_config
object with the given string.- Syntax is validated, and a character array is sized to fit all section names, keys, and values.
- The array is populated with values.
- Compiled result is the minimized array, with efficient functions for iteration and access.
