| eval exp module | Scheme Procedure |
| scm_eval (exp, module) | C Function |
Evaluate exp, a list representing a Scheme expression,
in the top-level environment specified by module.
While exp is evaluated (using primitive-eval),
module is made the current module. The current module
is reset to its previous value when eval returns.
|
| interaction-environment | Scheme Procedure |
| scm_interaction_environment () | C Function |
| Return a specifier for the environment that contains implementation-defined bindings, typically a superset of those listed in the report. The intent is that this procedure will return the environment in which the implementation would evaluate expressions dynamically typed by the user. |
| eval-string string | Scheme Procedure |
| scm_eval_string (string) | C Function |
Evaluate string as the text representation of a Scheme
form or forms, and return whatever value they produce.
Evaluation takes place in the environment returned by the
procedure interaction-environment.
|
| apply:nconc2last lst | Scheme Procedure |
| scm_nconc2last (lst) | C Function |
Given a list (arg1 ... args), this function
conses the arg1 ... arguments onto the front of
args, and returns the resulting list. Note that
args is a list; thus, the argument to this function is
a list whose last element is a list.
Note: Rather than do new consing, apply:nconc2last
destroys its argument, so use with care.
|
| apply proc arg1 ... args | Scheme Procedure |
proc must be a procedure and args must be a list. Call
proc with the elements of the list (append (list arg1
...) args) as the actual arguments.
|
| primitive-eval exp | Scheme Procedure |
| scm_primitive_eval (exp) | C Function |
| Evaluate exp in the top-level environment specified by the current module. |
