JSON Handling
JSON is the standard format for data exchange. The system.json module makes it easy to work with JSON in Quartz.
Parsing JSON
Convert a JSON string into Quartz dictionaries and arrays:
import system.io as io;
import system.json as json;
let raw = '{"name": "Quartz", "version": 0.5, "tags": ["brave", "small"]}';
let data = json.parse(raw);
io.out.println("Language:", data["name"]);
io.out.println("First tag:", data["tags"][0]);Generating JSON
Convert Quartz collections back into a JSON string:
import system.io as io;
import system.json as json;
let config = {
"debug": true,
"port": 8080,
"allowed_hosts": ["localhost", "127.0.0.1"]
};
let serialized = json.stringify(config);
io.out.println(serialized);Reading JSON from a File
Combine system.fs and system.json:
import system.io as io;
import system.fs as fs;
import system.json as json;
fn loadConfig(path) {
if (!fs.exists(path)) {
return {};
}
let raw = fs.read_file(path);
return json.parse(raw);
}
let myConfig = loadConfig("settings.json");
