Avasopht's Mighty Parser is a parsing framework for Java written in 2007 by Keldon Alleyne.

You can construct a mighty-parser definition using the example code listed below:

ArrayList<Node> alphaNumericList = new ArrayList<Node>();
ArrayList<Node> sentenceList = new ArrayList<Node>();
ArrayList<Node> anotherWordList = new ArrayList<Node>();
ArrayList<Node> wordList = new ArrayList<Node>();
ArrayList<Node> whitespaceList = new ArrayList<Node>();

Node whitespace;
Node word;
Node anotherWord;
Node sentence;

whitespaceList.add(TerminalFactory.createTerminalString(" "));
whitespaceList.add(RepetitionFactory.createRepetition(TerminalFactory.createTerminalString(" ")));
whitespace = ListFactory.createList(whitespaceList);

alphaNumericList.add(number());
alphaNumericList.add(letter());

wordList.add(letter());
wordList.add(RepetitionFactory.createRepetition(letter()));
word = ListFactory.createList(wordList);

anotherWordList.add(whitespace);
anotherWordList.add(word);
anotherWord = ListFactory.createList(anotherWordList);

sentenceList.add(word);
sentenceList.add(RepetitionFactory.createRepetition(anotherWord));
sentenceList.add(OptionFactory.createOptional(TerminalFactory.createTerminalString(".")));
sentence = ListFactory.createList(sentenceList);
