### 18`` Requiring Modules

( require unstable/require )

This module provides tools for importing from modules.

( require/provide module-path ...)

Re-exports all bindings provided by each module-path. Equivalent to:

( require module-path ... )
( provide ( all-from-out module-path ... ))

( quote-require require-spec ...)

Produces the names exported by the require-specs as a list of symbols.

Example:
> ( quote-require racket/bool racket/function)
'(false true symbol=? false? boolean=? negate curryr curry const)

( define-planet-package name package)

Defines a shortcut name for importing modules from planet package package. Subsequently, (name module ) is equivalent to ( planet package/module) as a require path. For instance, to import the text and web modules from this package:

( define-planet-package my-package cce/scheme)
( require (my-package web) (my-package text))

The above require is equivalent to:

( require ( planet cce/scheme/web) ( planet cce/scheme/text))

( define-collection name collect)

Defines a shortcut name for importing modules from collect and its subcollections. Subsequently, (name) is equivalent to collect as a require path, and (name path) is equivalent to collect/path.

( define-collection macro syntax )
( require (macro parse))

The above require is equivalent to the below:

( require syntax/parse)

( this-package-in path)

This require transformer imports the file at path in the current planet package. For instance, in the package ( planet cce/scheme:7), writing:
( require ( this-package-in function))
... is equivalent to writing:
( require ( planet cce/scheme:7/function))
