@title{R5RS: Legacy Scheme}

The @link[#:style r5rs-std "r5rs-std/index.html"]{The Revised@superscript{5} Report
on the Algorithmic Language Scheme} defines a dialect of Scheme. We
use @defterm{@|r5rs|} to refer to both the standard and the language
defined by the standard.

@margin-note{See @seclink[#:doc '(lib "scribblings/guide/guide.scrbl")
             "dialects"] for general information about different
             dialects of Scheme within Racket.}

The default dialect of Lisp provided by @exec{racket} and other
Racket tools differs from @|r5rs| in many ways, but Racket
includes tools and libraries for running @|r5rs| programs.

@; ----------------------------------------

@section[#:tag "running"]{Running @|r5rs| Programs}

Racket provides several layers of support for programs written
according to @|r5rs|:

@itemize[

 @item{DrRacket provides an @onscreen{R5RS} language, which can be
       selected via the @menuitem["Language" "Choose Language..."]
       menu item. See @seclink[#:doc drs-doc "choose-language"
       #:indirect? #t]{@onscreen{Choose Language...}} in
       @seclink["top" #:doc drs-doc #:indirect? #t]{the DrRacket
       documentation} for more information.}

 @item{The @exec{plt-r5rs} executable runs an @|r5rs| program or
       provides a read-eval-print loop for evaluating @|r5rs|
       expressions and definitions. See @secref["plt-r5rs"] (later in
       this manual) for more information.}

 @item{The @racketmodname[r5rs] library implemented @|r5rs| procedures
       and syntactic forms. It can also be used with @hash-lang[] to
       create a module whose body is implemented in an @|r5rs|-like
       language.  See @secref["r5rs-mod"] (later in this manual) for
       more information.}

 @item{The @racketmodname[r5rs/init] library extends
       @racketmodname[r5rs] to set parameters (such as
       case-insensitive symbol reading) for @|r5rs| loading or an
       @|r5rs| read-eval-print loop. See @secref["r5rs/init-mod"]
       (later in this manual) for more information.}

]

@; ----------------------------------------

@section[#:tag "plt-r5rs"]{@exec{plt-r5rs}}

The @exec{plt-r5rs} executable runs an @|r5rs| program from a file
that is supplied on the command line. If no program file is provided
as a command-line argument, then a read-eval-print loop is started.

Before starting a read-eval-print loop, an initialization file is
loaded, if it exists. The file is the same as the file reported by
@racket[(find-system-path 'init-file)], but with the characters
@litchar{racket} in the filename replaced by @litchar{pltr5rs}. For
example, on Unix, the file is @filepath{~/.pltr5rsrc}.

By default, @exec{plt-r5rs} departs from @|r5rs| conformance in one
crucial way: the names of pre-defined functions cannot be redefined at
the top level. This restriction enables better run-time
performance. Use the @as-index{@DFlag{no-prim}} command-line
flag---before a file to load, if any---to obtain the standard behavior
for primitive bindings (at the cost of performance).

@; ----------------------------------------

@section[#:tag "r5rs-mod"]{@|r5rs| Module Language}

@defmodulelang[r5rs]

As a library, @racketmodname[r5rs] provides the syntactic forms and
procedures defined by @|r5rs|. When used as a language via
@hash-lang[], the program is read with the following
parameterizations:

@racketblock[
  (read-case-sensitive #f)
  (read-accept-infix-dot #f)
  (read-curly-brace-as-paren #f)
  (read-square-bracket-as-paren #f)
]

The @racketmodname[r5rs] bindings can be imported into a top-level
environment, and then evaluation in that top-level environment
corresponds to @|r5rs|. Use @racket[(namespace-require/copy 'r5rs)]
with an empty namespace to maximize conformance with @|r5rs|; Using
@racket[(namespace-require 'r5rs)], in contrast, creates primitive
bindings as imports, which is the same as using
@seclink["plt-r5rs"]{@exec{plt-r5rs}} without the @DFlag{no-prim} flag.
More simply, use @racket[(scheme-report-environment 5)].  See also
@racketmodname[r5rs/init], which sets reader and printer parameters to
increase conformance.

Using @racketmodname[r5rs] via @hash-lang[] creates a module whose
body is implemented with an @|r5rs|-like language. The main difference
from @|r5rs| is that, as a module language, @racketmodname[r5rs] does
not allow redefinition of top-level bindings, and expressions
evaluated through @racket[load] and @racket[eval] cannot automatically
access bindings defined within the module.


@history[#:changed "6.0.1.4" @elem{When an identifier bound by
                                   @racket[letrec] is referenced
                                   before it is initialized, an
                                   exception is raised, instead of
                                   producing @|undefined-const|.}]

@; --------------------

@subsection{Non-@|r5rs| Bindings from @racketmodname[r5rs]}

In addition to the bindings defined by @|r5rs|, the
@racketmodname[r5rs] library provides the following bindings from
@racketmodname[racket/base] (which are not legal identifiers in @|r5rs|
syntax, so there is no danger of collisions in @|r5rs| programs):

@racketblock[
#%app #%datum #%top #%top-interaction #%require #%provide
]

It also provides a @racket[#%module-begin] binding as defined below.

Note that @racket[#%require] can be used to import Racket libraries
into an otherwise @|r5rs| program, and @racket[#%provide] can be used
to export from a module that is implemented in an @|r5rs|-like
language.

@history[#:changed "1.1" @elem{Added an @|r5rs|-specific @racket[#%module-begin],
                               instead of reexporting
                               @racketmodname[racket]'s @racket[#%plain-module-begin].}]

@defform[(#%module-begin form ...)]{

Besides allowing definitions and other forms like
@racketmodname[racket]'s @racket[#%plain-module-begin], defines a
@racketidfont{configure-runtime} submodule (see
@secref["configure-runtime" #:doc racket-doc]) that runs
@racketmodname[r5rs/init].}

@; --------------------

@subsection{Notes on @|r5rs| Functions}

The @racket[cons] of @racketmodname[r5rs] corresponds to
@racketmodname[racket/base]'s @racket[mcons]. Similarly, @racket[cdr]
is @racket[mcdr], and @racket[map] is @racketmodname[compatibility/mlist]'s
@racket[mmap], and so on.

An @|r5rs| @defterm{environment} is implemented as a
@racketmodname[racket/base] @defterm{namespace}. Also, relative to
@racketmodname[racket/base], the @racket[expr] passed to @racket[eval] is
constructed using mutable pairs.

The @racket[scheme-report-environment] function returns a namespace
containing the bindings of @racketmodname[r5rs].  Procedure values are
installed into the namespace using @racket[namespace-require/copy], so
that they can be redefined.

The @racket[null-environment] function returns a namespace
containing the syntactic forms of @racketmodname[r5rs], not including
@racket[#%module-begin] (which is not useful outside of a module).

@; ----------------------------------------

@section[#:tag "r5rs/init-mod"]{@|r5rs| Initialization Library}

@defmodule[r5rs/init]

The @racketmodname[r5rs/init] module re-exports @racketmodname[r5rs],
and also sets parameters as follows:

@racketblock[
  (read-case-sensitive #f)
  (read-accept-infix-dot #f)
  (read-curly-brace-as-paren #f)
  (read-square-bracket-as-paren #f)
  (print-mpair-curly-braces #f)
]

The side-effect of setting these parameters is useful when the module
is @racket[require]d before loading an @|r5rs| program, so that the
reader and printer behave more as specified in @|r5rs|. In particular,
the @seclink["plt-r5rs"]{@exec{plt-r5rs} executable} initializes by
importing @racketmodname[r5rs/init].
