(require mzlib/sandbox) | package: compatibility-lib

> NOTE: This library is deprecated; use racket/sandbox, instead.

The mzlib/sandbox library mostly re-exports racket/sandbox, but it provides a slightly different make-evaluator function.

The library re-exports the following bindings:

> sandbox-init-hook
> sandbox-reader
> sandbox-input
> sandbox-output
> sandbox-error-output
> sandbox-propagate-breaks
> sandbox-coverage-enabled
> sandbox-namespace-specs
> sandbox-override-collection-paths
> sandbox-security-guard
> sandbox-path-permissions
> sandbox-network-guard
> sandbox-make-inspector
> sandbox-eval-limits
> kill-evaluator
> break-evaluator
> set-eval-limits
> put-input
> get-output
> get-error-output
> get-uncovered-expressions
> call-with-limits
> with-limits
> exn:fail:resource?
> exn:fail:resource-resource

Like make-evaluator or make-module-evaluator, but with several differences:

- The language argument can be one of a fixed set of symbols: 'r5rs, etc. They are converted by adding a (list 'special ....) wrapper.

- If requires starts with 'begin, then each element in the remainder of the list is effectively evaluated as a prefix to the program. Otherwise, it corresponds to the #:requires argument of make-evaluator.

- For each of language and requires that starts with 'begin, the expressions are inspected to find top-level require forms (using symbolic equality to detect require), and the required modules are added to the #:allow list for make-evaluator.
