Tree Transformation Language
<functional language, rule-based language> (TXL) A hybrid functional
language and rule-based language developed by J.R. Cordy
<cordy@cs.queensu.ca> et al of Queen's University, Canada in 1988. TXL is
suitable for performing source to source analysis and transformation and for
rapidly prototyping new languages and language processors. It uses structural
transformation based on term rewriting.
TXL has been particularly successful in software engineering tasks such as
design recovery, refactoring, and reengineering. Most recently it has been
applied to artificial intelligence tasks such as recognition of hand-written
mathematics, and to transformation of structured documents in XML.
TXL takes as input an arbitrary context-free grammar in extended BNF-like
notation, and a set of show-by-example transformation rules to be applied to
inputs parsed using the grammar. TXL supports the notion of agile parsing, the
ability to tailor the grammar to each particular task using "grammar overrides".
Current version: FreeTXL 10.3, as of 2003-10-26.
