Names

From an LSL standpoint avatars can have 3 different names.

Modern and Legacy Accounts

• Modern accounts are created by choosing a user name, which consists of one name (no spaces).
• Legacy accounts were created by choosing two names: first and last names. These two names are used together to form the username.

To maintain compatibility with legacy scripts (that expect two names), modern accounts are given the legacy last name "Resident".

Default Display Name

The default value of the Display Name depends upon the type of the account. For modern accounts, it is the first part of the Legacy Name (without the space and last name "Resident"; this is the same as the Username with capitalization used at registration time preserved). For legacy accounts, it is the full Legacy Name.

string agentDefaultName(string agentUsername, string agentLegacyName) {
    integer i = llStringLength(agentUsername);
    if (i < llStringLength(agentLegacyName)) {
        // modern account
        return llDeleteSubString(agentLegacyName, i, -1);
    } else {
        // legacy account
        return agentLegacyName;
    }
}

Legacy Name to Username

The relationship between the Username and Legacy Name is simple. The Username for a specific Legacy Name is the Legacy Name in lowercase with the space replaced with a period. If the last name of the Legacy Name is "Resident", then the username is just the Legacy Name first name in lowercase (without the last name or the period).

string agentUsername(string agentLegacyName) {
    return llDumpList2String(llParseString2List(llToLower(agentLegacyName)+" ", [" resident ", " "],[]), ".");
}

If a Username is passed into this function instead of a Legacy Name, the Username will still be returned.

Other names

Complete Name

Viewer URI Name Space apparently also defines something called a Complete Name, which seems to be just the Display Name made unique by appending the Username in parenthesis when the Display Name is not set to its default value (and just the Display Name when it is set to its default value).

string agentCompleteName(string agentDisplayName, string agentUsername, string agentLegacyName) {
    if (agentDisplayName == agentDefaultName(agentUsername, agentLegacyName)) {
        return agentDisplayName;
    } else {
        return agentDisplayName + " (" + agentUsername + ")";
    }
}

Web Name

Some Second Life web pages (e.g., friends online: https://secondlife.com/my/account/friends.php or search results from: http://search.secondlife.com/) seem to return another form of naming similar to the Complete Name. This name is also just the Display Name made unique by appending a unique name in parenthesis when the Display Name is not set to its default value. The difference seems to be that the appended unique value is the default Display Name, instead of the Username, so this name always contains the default Display Name (with the current Display Name prepended).

string agentWebName(string agentDisplayName, string agentUsername, string agentLegacyName) {
    string agentDefaultName = agentDefaultName(agentUsername, agentLegacyName);
    if (agentDisplayName == agentDefaultName) {
        return agentDisplayName;
    } else {
        return agentDisplayName + " (" + agentDefaultName + ")";
    }
}

Legacy-Name Only Functions

These functions only take Legacy Names and there are no alternative functions available.

• llCollisionFilter
• llListen - likewise the listen event only has a Legacy Name parameter.
