# 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`.
|
|
|
|
[Try it on Godbolt.](https://godbolt.org/z/WTPzE3)
|
|
|
|
## 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
|
|
```cpp
|
|
#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 ""
|
|
```
|

## How it works (brief)
|
|
1. `_ini` prefix constructs an `ini_config` object with the given string.
|
|
2. Syntax is validated, and a character array is sized to fit all section names, keys, and values.
|
|
3. The array is populated with values.
|
|
4. Compiled result is the minimized array, with efficient functions for iteration and access.
