11 Non-Module Compilation And Expansion
| (require syntax/toplevel) | package: base |
procedure
(expand-syntax-top-level-with-compile-time-evals stx) → syntax?
stx : syntax?
Expands stx as a top-level expression, and evaluates its
compile-time portion for the benefit of later expansions.
The expander recognizes top-level begin expressions, and interleaves the evaluation and expansion of the begin body, so that compile-time expressions within the begin body affect later expansions within the body. (In other words, it ensures that expanding a begin is the same as expanding separate top-level expressions.)
The stx should have a context already, possibly introduced with namespace-syntax-introduce.
procedure
stx : syntax?
Like expand-syntax-top-level-with-compile-time-evals, but
stx is first given context by applying
namespace-syntax-introduce to it.
procedure
(expand-syntax-top-level-with-compile-time-evals/flatten stx)
→ (listof syntax?) stx : syntax?
Like expand-syntax-top-level-with-compile-time-evals, except
that it returns a list of syntax objects, none of which have a
begin. These syntax objects are the flattened out contents of
any begins in the expansion of stx.
procedure
stx : syntax?
Evaluates expansion-time code in the fully expanded top-level
expression represented by stx (or a part of it, in the case
of begin expressions). The expansion-time code might affect
the compilation of later top-level expressions. For example, if
stx is a require expression, then
namespace-require/expansion-time is used on each require
specification in the form. Normally, this function is used only by
expand-top-level-with-compile-time-evals.
procedure
→ (listof compiled-expression?) stx : syntax?
Like eval-compile-time-part-of-top-level, but the result is
compiled code.
