4.2.2 Documenting Modules
(defmodule maybe-req id maybe-sources pre-flow ...) |
|
maybe-req | | = | | | | | | | | #:require-form expr | | | | | | maybe-sources | | = | | | | | | | | #:use-sources (mod-path ...) |
|
Produces a sequence of flow elements (encaptured in a
splice)
to start the documentation for a module that can be
required
using the path
id. The
decoded
pre-flows
introduce the module, but need not include all of the module content.
Besides generating text, this form expands to a use of
declare-exporting with id; the
#:use-sources clause, if provided, is propagated to
declare-exporting. Consequently, defmodule should be
used at most once in a section, though it can be shadowed with
defmodules in sub-sections.
If a #:require-form clause is provided, the given expression
produces an element to use instead of (racket require) for
the declaration of the module. This is useful to suggest a different
way of accessing the module instead of through require.
Hyperlinks created by racketmodname are associated with the
enclosing section, rather than the local id text.
(defmodulelang id maybe-sources pre-flow ...) |
(defmodulelang content-expr #:module-paths (mod-path ...) | maybe-sources pre-flow ...) |
|
Like
defmodule, but documents
id as a module path
suitable for use by either
require or
#lang. If the
module path for
require is syntactically different from the
#lang form, use the
#:module-paths to provide them
separately.
Like
defmodule, but documents
id as a module path
suitable for use with
#reader.
(defmodule* maybe-req (id ...+) maybe-sources pre-flow ...) |
|
(defmodulelang* (id ...+) maybe-sources pre-flow ...) | (defmodulelang* (content-expr ...+) #:module-paths (mod-path ...+) | maybe-sources pre-flow ...) |
|
|
|
Like
defmodule, etc., but introduces multiple module paths instead
of just one.
Like
defmodule*, etc., but without expanding to
declare-exporting. Use this form when you want to provide a
more specific list of modules (e.g., to name both a specific module
and one that combines several modules) via your own
declare-exporting declaration.
(declare-exporting mod-path ... maybe-sources) |
|
maybe-sources | | = | | | | | | | | #:use-sources (mod-path ...) |
|
Associates the
mod-paths to all bindings defined within the
enclosing section, except as overridden by other
declare-exporting declarations in nested sub-sections. The
list of
mod-paths is shown, for example, when the user hovers
the mouse over one of the bindings defined within the section.
More significantly, the first mod-path plus the
#:use-sources mod-paths determine the binding that
is documented by each defform, defproc, or similar
form within the section that contains the declare-exporting
declaration:
If no #:use-sources clause is supplied, then the
documentation applies to the given name as exported by the first
mod-path.
If #:use-sources mod-paths are supplied, then
they are tried in order. The first one to provide an export
with the same symbolic name and
free-label-identifier=? to the given name is used as
the documented binding. This binding is assumed to be the same
as the identifier as exported by the first mod-path in
the declare-exporting declaration.
The initial mod-paths sequence can be empty if
mod-paths are given with #:use-sources. In that
case, the rendered documentation never reports an exporting module for
identifiers that are documented within the section, but the
mod-paths in #:use-sources provide a binding context
for connecting (via hyperlinks) definitions and uses of identifiers.
The declare-exporting form should be used no more than once
per section, since the declaration applies to the entire section,
although overriding declare-exporting forms can appear in
sub-sections.
