T-Gen - The Parser Generator for Visualworks
From the README:
SUMMARY T-gen Version 2.2.1.
T-gen is a general-purpose object-oriented tool for the
automatic generation of string-to-object translators.
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.
CURRENT STATUS
Apparently, Justin is not currently supporting T-Gen. Since it is such
a valuable tool, and I have used it extensively, I am now supporting
it. The current version works under Visualwork 2.5.2 and can be found here.
I am available for consulting work on projects that are attempting to
use T-gen. If you want enhancments or bugs fixes, contact me at:
