SDLang struct serialize

Rules

• use bool, string, int, double, Date, DateTimeFrac, Duration, ubyte[], structs and they arrays for fields type
• enum converts to strings
• byte, ubyte, short, ushort converts to int
• float and real converts to double
• attributes not used (see TODO)
• no value in sdl set default struct field value
• empty value in sdl for arrays set struct field to []
• structs arrays define as duplicate tags
• simple type arrays space separated values (ex "foo 1 2 3" -> int[] foo = [1,2,3])
• if multiple tag defined for settings fields used last

Example

app.d

struct Settings
{
    struct Com
    {
        string dev = "/dev/ttyUSB0";
        int baudrate = 19200;
        string mode = "8N1";
    }

    Com com;

    struct Data
    {
        string name;
        int[] signal;
    }

    Data[] data = [Data("first", [1, 1, 2, 3, 5])];
}

auto sets = readStruct!Settings("settings.sdl");

settings.sdl

com {
	dev "/dev/ttyUSB0"
	baudrate 19200
	mode "8N1"
}
data {
	name "first"
	signal 1 1 2 3 5
}
data {
    name "second"
    signal 1 4 8
}
