ParCinJ

ParCinJ is a Java™ library for constructing parsers. It stands for Parser Constructor in Java.

Fluent Interface API with an EBNF-like internal DSL
No code generation

Assuming you want to write a parser which parses nested lists like

(a, b, (c1, c2, ()), d)

In an EBNF-like grammar language (like ANTLR) you would write

list: '(' (element (',' element)*)? ')';
element: ATOM | list;

With ParCinJ's fluent interface API you write following Java code:

    NonTerminalSymbol<P> list = new NonTerminalSymbol<P>("list")
    NonTerminalSymbol<P> element = new NonTerminalSymbol<P>("element");
    TerminalSymbol<P> atom = new TerminalSymbolByType<P>(NormalToken.NORMAL_TOKEN);
    TerminalSymbol<P> open = new TerminalSymbolByText<P>("(");
    TerminalSymbol<P> comma = new TerminalSymbolByText<P>(",");
    TerminalSymbol<P> close = new TerminalSymbolByText<P>(")");
    
    list.definedBy(open
                   .followedBy(element.followedBy(comma.followedBy(element).zeroOrMoreTimes()).optional())
                   .followedBy(close));
    element.definedBy(atom.or(list));

and are classes implementing the interface . It provides the method process which does the actual parsing. To do the job it needs a and a . The TokenIterator is provided by a which turns a stream of characters into a stream of . Processor is only a marker interface of classes which implement particular methods for processing Tokens in certain steps of the parsing process. All symbols are generic classes for a particular processor.

For details see the User Guide or study the examples in src.zip of the distribution.
