@ -38,6 +38,59 @@ This module provides a single procedure:
Expands the syntax (or S-expression) and opens a macro stepper frame
for stepping through the expansion.
_expand.ss_
===========
> (require (lib "expand.ss" "macro-debugger"))
This module provides the following procedures:
> expand/step
This export will disappear in a future version of the collection.
Require from stepper.ss instead.
> (expand-only syntax list-of-identifiers)
Expands the given syntax, but only shows the expansion of macros in
the given identifier list.
Warning: because of limitations in syntax, expansion, and hiding, the
resulting syntax may not evaluate to the same thing as the original
syntax.
> (expand/hide syntax list-of-identifier)
Expands the given syntax, but hides the expansion of macros in the
given identifier list (conceptually, the complement of expand-only).
Warning: because of limitations in syntax, expansion, and hiding, the
resulting syntax may not evaluate to the same thing as the original
syntax.
_stepper-text.ss_
=================
> (require (lib "stepper-text.ss" "macro-debugger"))
This module provides two procedures for stepping through macro
expansion in text-only environments.
> (expand/step-text syntax [identifier-predicate])
Expands the syntax and prints the macro expansion steps. If the
identifier predicate is given, it determines which macros are shown
(if absent, no macros are hidden). A list of identifiers is also
accepted.
> (stepper-text syntax [identifier-predicate])
Returns a procedure P that:
- when called with no arguments (or on the symbol 'next),
prints out individual steps until macro expansion finishes
- when called on the symbol 'all,
prints out all of the remaining steps
