Antlr GenProject provides a command line wizard for generating an Antlr4 project framework with a fairly standard form. The directory structure is compatible with standard Eclipse/Java projects.

Descriptor pattern: a full set of descriptor classes are generated automatically from the Antlr generated files. The descriptor classes are type-specific to the parse tree context nodes defined by the project grammar. The default instantiation of the descriptors uses a decoration pattern allowing simple access to the parse tree contexts and corresponding descriptors.

Converter pattern: a generated converter class implements a serial procedure for lexing, parsing, and walking operations. Multiple, sequential walking phases are supported with the passing forward of state between phases. A full symbol table implementation is provided as part of the default state object. As generated, phase 1 constructs and initializes the descriptor object set and phase 2 invokes a process method on each descriptor object.
