Detailed Description

template<typename Manifest>
class ml::ConfigManager< Manifest >

Manifest-driven accessor for typed configuration values.

ConfigManager<Manifest> provides typed get() overloads for each configuration enum declared in a manifest. Each overload is enabled only when the corresponding enum exists, so missing config types are caught at compile time.

Manifest config enums

Enum name in manifest	Value type	Example
Text	std::string	Window title, labels
Ints	int	Max players, tile size
Floats	float	Speed multiplier, volume
Booleans	bool	Debug mode, fullscreen

Usage

class MyManifest : public ml::Manifest {
public:
    enum class Text    { Title };
    enum class Ints    { MaxPlayers };
    enum class Floats  { Speed };
private:
    inline static const auto _ = [](){
        set(Text::Title,       std::string("My Game"));
        set(Ints::MaxPlayers,  4);
        set(Floats::Speed,     1.5f);
        return 0;
    }();
};
 
const std::string& title = ml::ConfigManager<MyManifest>::get(MyManifest::Text::Title);
int maxPlayers            = ml::ConfigManager<MyManifest>::get(MyManifest::Ints::MaxPlayers);
float speed               = ml::ConfigManager<MyManifest>::get(MyManifest::Floats::Speed);

Or more conveniently via Context:

struct MyCtx : public ml::Context<MyManifest> {};
const std::string& title = MyCtx::ConfigMgr::get(MyManifest::Text::Title);

Template Parameters

Manifest

A Manifest subclass declaring config enums (Text, Ints, Floats, Booleans).

Member Function Documentation

ensureInitialized()

template<typename Manifest>

void ml::ConfigManager< Manifest >::ensureInitialized ( )

static

Ensure the manifest's config values have been registered.

Called internally before the first get() access. May be called explicitly if you need to guarantee initialization order.

get() [1/4]

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Booleans< M >::value, bool > ml::ConfigManager< Manifest >::get ( typename M::Booleans config )

static

Retrieve a boolean config value.

Only available when Manifest declares a Booleans enum.

Parameters

config

The Booleans enum value to look up.

Returns

The registered bool value.

get() [2/4]

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Floats< M >::value, float > ml::ConfigManager< Manifest >::get ( typename M::Floats config )

static

Retrieve a float config value.

Only available when Manifest declares a Floats enum.

Parameters

config

The Floats enum value to look up.

Returns

The registered float value.

get() [3/4]

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Ints< M >::value, int > ml::ConfigManager< Manifest >::get ( typename M::Integers config )

static

Retrieve an integer config value.

Only available when Manifest declares an Ints enum.

Parameters

config

The Ints enum value to look up.

Returns

The registered int value.

get() [4/4]

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Strings< M >::value, const std::string & > ml::ConfigManager< Manifest >::get ( typename M::Text config )

static

Retrieve a string config value.

Only available when Manifest declares a Text enum.

Parameters

config

The Text enum value to look up.

Returns

Const reference to the registered std::string value.
