Thus, Lisp programs can manipulate source code as a data structure, giving rise to the macro systems that allow programmers to create new syntax or new domain-specific languages embedded in Lisp. The interchangeability of code and data gives Lisp its instantly recognizable syntax. All program code is written as s-expressions, or parenthesized ...
POP-2/11 · Python · R · Rebol · Red · Ruby · Scala · Swift · Smalltalk · Tcl · Wolfram Language[2] Lisp (programming language) Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation.[3] Originally specified in
Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). [2] [3] Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte. [4] Lisp allows operating on code as data (metaprogramming), thus Hy can be used to write domain-specific ...
The programming language Lisp is the second-oldest high-level programming language with direct descendants and closely related dialects still in widespread use today. The language Fortran is older by one year. [1] [2] Lisp, like Fortran, has changed a lot since its early days, and many dialects have existed over its history.
ECL includes a bytecode interpreter and compiler. It can also compile Lisp code to machine code via a C compiler. ECL then compiles Lisp code to C, compiles the C code with a C compiler and can then load the resulting machine code. It is also possible to embed ECL in C programs, and C code into Common Lisp programs. GNU Common Lisp (GCL)
The following is an example in Common Lisp using the Common Lisp Object System: ( defclass foo () ()) ( defmethod print-hello (( f foo )) ( format T "Hello from ~S~%" f )) ;; Normal, without reflection ( let (( foo ( make-instance 'foo ))) ( print-hello foo )) ;; With reflection to look up the class named "foo" and the method ;; named "print ...
In 1964, the expression READ-EVAL-PRINT cycle is used by L. Peter Deutsch and Edmund Berkeley for an implementation of Lisp on the PDP-1. [3] Just one month later, Project Mac published a report by Joseph Weizenbaum (the creator of ELIZA, the world's first chatbot) describing a REPL-based language, called OPL-1, implemented in his Fortran-SLIP language on the Compatible Time Sharing System (CTSS).
A native code compiler named "Python" (not to be confused with the Python programming language). If Common Lisp source code has been written with appropriate declarations and is organized with speed in mind the Python compiler generates code that is almost free from overhead compared to code compiled from languages like C++.
