* The Config class provides Nix runtime configurations.

*
|

* What is a Configuration?
|
||||
* A collection of uniquely named Settings.
|
||||
*
|
||||
* What is a Setting?
|
||||
* Each property that you can set in a configuration corresponds to a
|
||||
* `Setting`. A setting records value and description of a property
|
||||
* with a default and optional aliases.
|
||||
*
|
||||
* A valid configuration consists of settings that are registered to a
|
||||
* `Config` object instance:
|
||||
*
|
||||
* Config config;
|
||||
* Setting<std::string> systemSetting{&config, "x86_64-linux", "system", "the current system"};
|
||||
*
|
||||
* The above creates a `Config` object and registers a setting called "system"
|
||||
* via the variable `systemSetting` with it. The setting defaults to the string
|
||||
* "x86_64-linux", it's description is "the current system". All of the
|
||||
* registered settings can then be accessed as shown below:
|
||||
*
|
||||
* std::map<std::string, Config::SettingInfo> settings;
|
||||
* config.getSettings(settings);
|
||||
* config["system"].description == "the current system"
|
||||
* config["system"].value == "x86_64-linux"
|
||||
*
|
||||
*
|
||||
* The above retrieves all currently known settings from the `Config` object
|
||||
* and adds them to the `settings` map.
