TXR is a "data munging" language which combines a convenient text extraction notation that is equivalent in power to Parse Expression Grammars, with an innovative Lisp dialect which manages to integrate the differences between Lisp-1 and Lisp-2. It has many features: built-in lazy lists, strings and vectors that can be treated with list processing functions, currying operators, macros with destructuring lambda lists, macrolet, symbol macros, dynamically scoped variables, exception handling, object-oriented structures, delimited continuations, structural pattern matching a foreign-function interface and more. TXR is influenced by Common Lisp, Scheme, Awk, M4, POSIX Shell, Prolog, Ruby, Python, Arc, Clojure, S-Lang and others.
