I guess I meant types that have an obvious mapping to json types.
int/long -> json integer
bool -> json bool
string -> json string
float/real -> json float (close enough)
T[] -> json array
T[string] -> json object
struct -> json object
This is usually enough for config and data files. Being able to do this is
just awesome:
struct AppConfig
{
string somePath;
bool someOption;
string[] someList;
string[string] someMap;
}
void main()
{
auto config = "config.json".readText().parseJSON().fromJson!AppConfig();
}
Being able to serialize whole graphs into json is something I need much less
often.
