    39== Getting started
    2127Scheme is a member of the Lisp family of languages, of which Common
    22 Lisp and Emacs Lisp are the other two widely-known members. As with
     28Lisp, Emacs Lisp and Clojure are other widely-known members. As with
    2329Lisp dialects, Scheme features
    3036include only those features absolutely necessary in programming. In
    3137contrast to Emacs Lisp, Scheme is not anchored into a single program

     39to Clojure, Scheme provides only a very minimal set of concepts but allows
     40them to be used in very general ways with few restrictions.

    3846report, ''R6RS'', was
    3947released in 2007, but this report has attracted considerable

     49not to be compliant

     51less ambitious than R6RS and more minimal.

    55 The CHICKEN community is at present developing tutorials for
    56 programmers who are new to Scheme but experienced with Python, Ruby,
    57 or other languages. These can be found on the CHICKEN wiki.
    5968=== CHICKEN
    61 CHICKEN is an implementation of Scheme that has many advantages.
    6370CHICKEN Scheme combines an optimising compiler with a reasonably fast
    64 interpreter.  It supports almost all of R5RS and the important SRFIs.

    119   UNIX or Windows
    120124* Compiled C files can be easily distributed
    121125* Allows the creation of fully self-contained statically linked executables
    125129CHICKEN has been used in many environments ranging from embedded
    126130systems through desktop machines to large-scale server deployments.

    223228using the interpreter and/or calling the compiler.  If you install one
    224229of the line editing extensions (e.g., [[/egg/readline|readline]],
    225 [[/egg/parley|parley]], [[/egg/linenoise|linenoise]], you have some
     230[[/egg/parley|parley]], [[/egg/linenoise|linenoise]]), you have some
    226231useful command line editing features in the interpreter (e.g., Emacs
    227232or vi-compatible line editing, customization).
    229 You will need a text editor that knows Scheme; it's just too painful
     234It will be helpful to use a text editor that knows Scheme; it can be painful
    230235with editors that don't do parenthesis matching and proper
    231 indentation. Some editors allow you to execute Scheme code directly in
    232 the editor. This makes programming very interactive: you can type in a
    233 function and then try it right away. This feature is very highly
    234 recommended.
    236 As programmers have very specific tastes about editors, the editors
    237 listed here are shown in alphabetic order. We aren't about to tell you
    238 which editor to use, and there may be editors not shown here that
    239 might satisfy your needs. We would be very interested in reports of
    240 other editors that have been used with CHICKEN, especially those that
    241 support interactive evaluation of forms during editing. Pointers to
    242 these (and to any editor customization files appropriate) should be
    243 put on the CHICKEN wiki, and will likely be added to future editions
    244 of this manual. (We have had a request for editors that support
    245 proportional fonts, in particular.)
    247 * Emacs ([[]]) is an
    248 extensible, customizable, self-documenting editor available for
    249 Linux/Unix, Macintosh, and Windows systems; See
    250 [[|]]
    251 for more information about the available options.
    253 * SciTE ([[]]),
    254 unlike Emacs or Vim, follows typical graphical UI design conventions
    255 and control-key mappings, and for simple tasks is as familiar and
    256 easy to use as Notepad, KEdit, TeachText etc.  However it has many
    257 programming features such as multiple open files, syntax
    258 highlighting for a large number of languages (including Lisps),
    259 matching of brackets, ability to fold sections of code based on the
    260 matched brackets, column selections, comment/uncomment, and the
    261 ability to run commands in the same directory as the current file
    262 (such as make, grep, etc.)  SciTE is written with the GTK toolkit
    263 and is portable to any GTK platform, including Windows, Linux and
    264 MacOS.  It uses the Scintilla text-editing component, which lends
    265 itself well to embedding within other IDEs and graphical toolkits.
    266 It does not have any other Scheme-specific features, but being
    267 open-source and modular, features like auto-formatting of
    268 S-expressions could be added.  The syntax highlighting can be
    269 configured to use different fonts for different types of syntax,
    270 including proportional fonts.
    272 * Vim ([[]]) is a highly configurable text
    273 editor built to enable efficient and fast text editing. It is an
    274 improved version of the vi editor distributed with most UNIX systems.
    275 Vim comes with generic Lisp (and therefore Scheme) editing capabilities
    276 out of the box. See [[/Vim]] for a few tips on using Vim with CHICKEN.
    278238In the rest of this chapter, we'll assume that you are using an editor
    393353  users aren't expected to have CHICKEN installed: compiled
    394354  applications can be self-contained.
     355* Compiled code can access external libraries written in lower-level
     356  languages that follow the C calling convention.
    396358The CHICKEN compiler is provided as the command {{chicken}}, but in
    410372We can compile our factorial function, producing a file named
    411 {{}} (''shared object'' in Linux-ese, the same file type is
    412 used in OS X and Windows, rather than {{dylib}} or {{dll}},
    413 respectively).
    415  chicken$ csc -dynamic fact.scm
     373{{}} (''shared object'' in Linux-ese, the same file extension is
     374used in Windows, rather than {{dll}})
     376 chicken$ csc -shared fact.scm
    416377 chicken$ csi -quiet
    417378 #;1> (load "")
    542503Because CHICKEN compiles to C, and because a foreign function
    543504interface is built into the compiler, interfacing to a C library is
    544 quite straightforward. This means that nearly any facility available
     505quite straightforward. This means that any facility available
    545506on the host system is accessible from CHICKEN, with more or less
