_R5RS_
The "r5rs.ss" module in the "r5rs" collection implements the language
defined by the "Revised^5 Report on the Algorithmic Language Scheme".
In addition, this module provides _#%provide_ (instead of `provide'),
_#%require_ (instead of `#%require'), `#%app', `%datum', etc. The
`letrec' of this language is defined exactly as in R5RS, and not as in
MzScheme.
The "r5rs" collection implements the language defined by the
"Revised^5 Report on the Algorithmic Language Scheme" in the "lang.ss"
module. In addition, this module provides _#%provide_ (instead of
`provide'), _#%require_ (instead of `#%require'), `#%app', `%datum',
etc. The `letrec' of this language is defined exactly as in R5RS, and
not as in MzScheme.
The module _r5rs.ss_ module is a language module. You can use it in
one of several ways:
You can use this collection in several ways:
* Use the "Standard (R5RS)" language in DrScheme;
* Use the "Standard (R5RS)" language in DrScheme.
* Write code in a module using the R5RS module (lib "lang.ss" "r5rs"),
as a base language:
(module foo (lib "lang.ss" "r5rs")
...)
in this case, you can `provide' bindings and `require' other modules
by using _#%require_ and _#%provide_.
* Start MzScheme using bindings from the R5RS language with
mzscheme -M r5rs
(but note that MzScheme bindings will still be visible);
* Write code in a module that uses the R5RS language:
(module foo (lib "r5rs.ss" "r5rs")
...)
in this case, you can `provide' bindings and `require' other modules
by using _#%require_ and _#%provide_.
This will start MzScheme with only the R5RS bindings (with #%require
etc), and a reader that will reject use of square brackets and curly
braces.
