the class CandidateListCompletionHandler method complete.

public boolean complete(ConsoleReader reader, @SuppressWarnings("rawtypes") List<CharSequence> candidates, int pos) throws IOException {
    CursorBuffer buf = reader.getCursorBuffer();
    // if there is only one completion, then fill in the buffer
    if (candidates.size() == 1) {
        String value = candidates.get(0).toString();
        // fail if the only candidate is the same as the current buffer
        if (value.equals(buf.toString())) {
            return false;
        }
        jline.console.completer.CandidateListCompletionHandler.setBuffer(reader, value, pos);

    }
    if (eagerNewlines) {
