TXR is a fusion of many different ideas, a few of which are original, and it is influenced by many languages, such as Common Lisp, Scheme, Awk, M4, POSIX Shell, Prolog, Ruby, Python, Arc, Clojure, S-Lang and others.
TXR consists of two languages, which can be used separately or tangled together: the TXR Pattern Language, and TXR Lisp.
