Examples

Tests out the working with the registry in order to manage a set of named configuration entries

Registry reg = Registry(false);

// Add an entry
reg.newEntry("name", "Tristan");

// Check it exists
assert(reg.hasEntry("name"));

// Adding it again should fail
try
{
    reg.newEntry("name", "Tristan2");
    assert(false);
}
catch(RegistryException e)
{

}

// Check that the entry still has the right value
assert(cast(string)reg["name"] == "Tristan");

// // Add a new entry and test its prescence
reg["age"] = 24;
assert(cast(int)reg["age"]);

// // Update it
reg["age"] = 25;
assert(cast(int)reg["age"] == 25);

// Obtain a handle on the configuration
// entry, then update it and read it back
// to confirm
ConfigEntry* ageEntry = "age" in reg;
*ageEntry = ConfigEntry.ofNumeric(69_420);
assert(cast(int)reg["age"] == 69_420);

// Should not be able to set entry it not yet existent
try
{
    reg.setEntry("male", ConfigEntry.ofFlag(true));
    assert(false);
}
catch(RegistryException e)
{

}

// All entries
RegistryEntry[] all = reg[];
assert(all.length == 2);
writeln(all);
