Some examples of Midgard2 GIR usage

test-gjs.js

// Get Midgard via GIR
const Midgard = imports.gi.Midgard;
Midgard.init();
print(Midgard.version());

var config = new Midgard.Config();
config.dbtype = 'SQLite';
config.dbdir = '/tmp';
config.database = 'phpcr';
config.loglevel = 'debug';
print(config.get_database_type());

var connection = new Midgard.Connection();
connection.open_config(config);

var storage = new Midgard.QueryStorage({
  dbclass: 'midgard_node'
});

var qs = new Midgard.QuerySelect({
  connection: connection,
  storage: storage
});
qs.execute();
var nodes = qs.list_objects();
for (var i in nodes) {
  print(nodes[i].name);
}
