|
@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/interactive)]{
|
|
The @racketmodname[racket/interactive] is the default start
|
|
up library when the REPL begins. It is not run if the
|
|
@Flag{q}/@DFlag{no-init-file} is specified. The interactive
|
|
file can be changed by modifying @racket['interactive-file] in the
|
|
@filepath{config.rktd} file found in
|
|
@racket[(find-config-dir)]. Alternative, if the file
|
|
@filepath{interactive.rkt} exists in
|
|
@racket[(find-system-path 'addon-dir)] it is run rather
|
|
than the installation wide interactive module.
|
|
|
|
The default interactive module starts @racketmodname[xrepl] and
|
|
runs the @racket[(find-system-path 'init-file)] file in the users home directory. A
|
|
different interactive file can keep this behavior by
|
|
requiring @racketmodname[racket/interactive].

|
|
|
|
|
|
@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.
