The Essentials editioh Programming Languages language in DrRacket provides a subset of functions and syntactic forms of racket — mostly the ones that correspond to r5rs forms.

See below for a complete list. The language is intended for use with the textbook [ EoPL ].

The following bindings are re- provide d from racket:. In DrScheme v and older, when constructor-based printing was used, variant instances were printed with a make- prefix before the variant name.


Thus, for compatibility, in addition to variant-idmake-variant-id is also defined for each variant-id to the same constructor as variant-id. The eopl library sets this variable to f in the current namespace when it executes. The eopl library calls this function when it executes.

Essentials of Programming Languages Language define- datatype cases sllgen: Defines the datatype id and a function predicate-id that returns t for instances erition the datatype, and f for any other value. Branches on the datatype instance produced by exprwhich must be an instance of the specified datatype-id that is defined with define-datatype.

However, the DrRacket versions are syntactic forms, instead of procedures, and the arguments must be either quoted literal tables or identifiers that are defined at the top level to quoted literal tables. Evaluates expr eoll, and prints timing information before returning the result.

The untrace form reverses the action of trace for the given id s. Useful only with a module that uses eopl as a language: See provide from racket for more information.


Defined only in the top-level namespace i. Typically, the handler thunk escapes through a continuation.

Sets an exception handler to one that checks eopl: Essentials of Programming Languages Language.
