Guile is a programming language

   Guile is designed to help programmers create flexible applications that can be
   extended by users or other programmers with plug-ins, modules, or scripts.

   With Guile you can create applications and games for the [7]desktop, the [8]Web,
   the [9]command-line, and more.

Code examples

   Guile is an implementation of the [12]Scheme programming language, supporting the
   [13]Revised^5 and most of the [14]Revised^6 language reports, as well as many
   [15]SRFIs. It also comes with a library of modules that offer additional
   features, like an HTTP server and client, XML parsing, and object-oriented
   programming.
;;; Hello world program
(define name "World")
(display (string-append "Hello " name "!"))
(newline)

  Hello world program

   [16]Define a variable called name, join the texts Hello, name, and ! together to
   form the greeting Hello world!, and display it on the screen.
;;; Show current date and time
(use-modules (srfi srfi-19))

(display (date->string (current-date)
                       "~A, ~B ~e ~Y ~H:~S"))
(newline)

  Importing modules

   [17]Import the [18]srfi-19 module and use its functions to display the current
   date and time in the format WEEKDAY, MONTH MONTHDAY YEAR HOUR:SECOND.
;;; Hello HTTP server
(use-modules (web server))

(define (my-handler request request-body)
  (values '((content-type . (text/plain)))
          "Hello World!"))

(run-server my-handler)

  Hello HTTP server

   Run a [19]Web server that will return a response with the text "Hello World!" to
   every request sent by HTTP clients. Open http://localhost:8080/ to see the
   result.

Guile is an extension language platform

   Guile contains an efficient compiler and virtual machine. It can be used out of
   the box to write programs in Scheme, or can easily be integrated with C and C++
   programs.

   Guile is the GNU Ubiquitous Intelligent Language for Extensions, and the official
   extension language of the [20]GNU project.

Extend applications

   In addition to Scheme, Guile includes compiler front-ends for [21]ECMAScript and
   [22]Emacs Lisp (support is underway for [23]Lua), which means your application
   may be extended in the language (or languages) most appropriate for your user
   base. And Guile's tools for parsing and compiling are exposed as part of its
   standard module set, so support for additional languages can be added without
   writing a single line of C.

Guile empowers users with "practical software freedom"

   Using any of the supported scripting languages, users can customize and extend
   applications while they are running and see the changes take place live!

   Users can easily trade and share features by uploading and downloading the
   scripts, instead of trading complex patches and recompiling their applications.
