'''Red''' is both an [[imperative programming|imperative]] and [[functional programming]] [[programming language|language]] introduced in 2011 by Nenad Rakocevic. Its syntax and general usage directly overlaps with that of the interpreted [[Rebol]] language (which was introduced in 1997). Yet the implementation choices of Red were geared specifically to overcoming limitations of Rebol, creating what Rakocevic calls a "full stack programming language". Red can be used for extremely high-level programming ([[Domain-specific language|DSL]]s and [[Graphical user interface|GUI]]s) as well as low-level programming ([[Operatingoperating system|operating systems]]s and [[Devicedevice driver|device drivers]]s).

Key to the approach is that the language has two parts: '''Red/System''' and '''Red'''. The former is similar to C, but packaged into a Rebol lexical structure ''(e.g. one would write "if x > y [print {Hello}]" instead of "if (x > y) {printf("Hello\n");}")''. Red itself is a [[Homoiconicity|homoiconic language]] capable of meta-programming, whose semantics are more similar to Rebol's. Its runtime library is written in Red/System, and uses a hybrid approach: it [[Compiled language|compiles]] what it can deduce statically, has a [[Just-in-time compilation|just-in-time compiler]] for cases that can make use of it, and falls back onto an embedded [[Interpreter_Interpreter (computing)|interpreter]] when neither of those approaches will suffice.

Red seeks to remain independent of any other toolchain, and thus does its own code generation. It's therefore possible to [[Cross compiler|cross-compile]] Red programs from any platform it supports to any other, via a command-line switch. Both Red and Red/System are distributed as [[open-source software]] under the [[BSD licenses#3-clause_license_clause license .28.22New_BSD_License22New BSD License.22_or_22 or .22Modified_BSD_License22Modified BSD License.22.29|modified BSD license]]. The runtime library is distributed under the more permissive [[Boost Software License]].
