A file configuration manager library that simplify access of json configuration files from a dir.
if a config file is not existing, it will be created. Any var is accessed by a path. Saving use atomic method disallowing partial load from other app/process/etc.
the used serde_json crate is re-exported via "Hconfig::serde_json"
fn main()
{
// configuration path, the directory need to be existing or created before continuing
HConfigManager::singleton().setConfPath("./config");
// get a "config", the name "example" mean "./config/example.json"
let mut config = HConfigManager::singleton().get("example");
// exemple of getting a var and getting a string (parse is from serde_json)
let myVar: Option<Value> = config.get("name");
let myString: String = config.get("path/to/myvar").unwrap().as_str().unwrap().to_string();
config.set("path/to/save",JsonValue::String("test is update".to_string()));
// save config modification.
config.save();
}
