TXL (programming language) (original) (raw)

TXL is a special-purpose programming language originally designed by and James Cordy at the University of Toronto in 1985. The acronym "TXL" originally stood for "Turing eXtender Language" after the language's original purpose, the specification and rapid prototyping of variants and extensions of the Turing programming language, but no longer has any meaningful interpretation. The first component parses the input expression into a tree using pattern-matching. The second component uses Term-rewriting in a manner similar to Yacc to produce the transformed output.
