The `#%module-begin' of `racket/base' and `scheme/base' now introduces a suitable `configure-runtime' submodule, instead of using the `module->language-info' path. A submodule is a lot easier to work with, as illustrated by the removal of the `racket/private/lang' and `scheme/private/lang' languages. Also, add `#%printing-module-begin', which is the old `#%module-begin' (i.e., the one that doesn't introduce a `configure-runtime' submodule).

@defmodule*/no-declare[(racket/init)]{The @racketmodname[racket/init]
|
|
library is the default start-up library for Racket. It re-exports
|
|
the @racketmodname[racket], @racketmodname[racket/enter] and
|
|
@racketmodname[racket/help] libraries, and it sets
|
|
@racket[current-print] to use @racket[pretty-print].}

@defmodule*/no-declare[(racket/gui/init)]{The
|
|
@racketmodname[racket/gui/init] library is the default start-up
|
|
library for GRacket. It re-exports the @racketmodname[racket/init] and
|
|
@racketmodname[racket/gui/base] libraries, and it sets
|
|
@racket[current-load] to use @racket[text-editor-load-handler].}
|
|
|
|
@defmodule*/no-declare[(racket/language-info)]{The
|
|
@racketmodname[racket/language-info] library provides a
|
|
@racketidfont{get-info} function that takes any value and returns
|
|
another function; the returned function takes a key value and a
|
|
default value, and it returns @racket['(#(racket/runtime-config
|
|
configure #f))] if the key is @racket['configure-runtime] or the
|
|
default value otherwise.}

|
@guidealso["module-runtime-config"]
|
|
|
|
The vector @racket['#(racket/language-info get-info #f)] is suitable
|
|
for attaching to a module as its language info to get the same
|
|
language information as the @racket[racket/base] language.
|
|
|
|
@defmodule*/no-declare[(racket/runtime-config)]{The
|
|
@racketmodname[racket/runtime-config] library provides a
|
|
@racketidfont{configure} function that takes any value
|
|
and sets @racket[print-as-expression]
|
|
to @racket[#t].}
|
|
|
|
The vector @racket[#(racket/runtime-config configure #f)] is suitable
|
|
as a member of a list of runtime-configuration specification (as
|
|
returned by a module's language-information function for the key
|
|
@racket['configure-runtime]) to obtain the same runtime configuration as
|
|
for the @racketmodname[racket/base] language.
