It is written in Smalltalk and lives in the Smalltalk programming environment. T-gen supports the generation of both top-down (LL) and bottom-up (LR) parsers, which will automatically generate derivation trees, abstract syntax trees, or arbitrary Smalltalk objects. The simple specification syntax and graphical user interface are intended to enhance the learning, comprehension, and usefulness of T-gen.<H2>CURRENT STATUS</H2> <P>Apparently, Justin is not currently supporting T-Gen. Since it is sucha valuable tool, and I have used it extensively, I am now supportingit. The current version works under Visualwork 2.5.2 and can be found <AHREF="http://st-www.cs.uiuc.edu/users/droberts/tgen2.2.1/">here</A>.</P><P>I am available for consulting work on projects that are attempting touse T-gen.
