@defmodule[scribble/struct]{
|
|
The @scheme[scribble/struct] compatibility library mostly re-exports
|
|
@scheme[scribble/core], but using some different names (e.g.,
|
|
@scheme[blockquote] instead of @scheme[nested-flow]).}
|
|
|
|
The following structure types and functions are re-exported directly:
|
|
|
|
@schemeblock[collect-info resolve-info tag? block?
|
|
delayed-block collected-info delayed-element ; delayed-element-content delayed-block-blocks current-serialize-resolve-info

|
|
resolve-get resolve-get/tentative resolve-get/ext?
|
|
resolve-search resolve-get-keys]
|
|
|
|
The following structure types are re-exported, but the constructors and some selectors
|
|
are replaced as documented further below:
|
|
|
|
@schemeblock[part paragraph table itemization compound-paragraph
|
|
element toc-element target-element toc-target-element
|
|
page-target-element redirect-target-element link-element
|
|
index-element]
|
|
|
|
Several additional compatibility functions and structure types are
|
|
also exported.
