@title[#:tag "basic"]{Basic Document Forms}
|
|
|
|
@defmodule[scribble/basic]{The @schememodname[scribble/basic] libraryp
|
|
rovides functions and forms that can be used from code written either
|
|
in Scheme or with @elem["@"] expressions.}
|
|
|
|
For example, the @scheme[title] and @scheme[italic] functions might be
|
|
called from Scheme as
|
|
|
|
@schemeblock[
|
|
(title #:tag "how-to"
|
|
"How to Design " (italic "Great") " Programs")
|
|
]
|
|
|
|
or with an @elem["@"] expression as
|
|
|
|
@verbatim[#:indent 2]|{
|
|
@title[#:tag "how-to"]{How to Design @italic{Great} Programs}
|
|
}|
|
|
|
|
Although the procedures are mostly design to be used from @elem["@"]
|
|
mode, they are easier to document in Scheme mode (partly because we
|
|
have @schememodname[scribble/manual]).

[#:version vers (or/c string? false/c) #f]

[pre-content any/c] ...+)
|
|
title-decl?]{
|
|
|
|
Generates a @scheme[title-decl] to be picked up by @scheme[decode] or
|
|
@scheme[decode-part]. The @tech{decode}d @scheme[pre-content] (i.e.,
|
|
parsed with @scheme[decode-content]) supplies the title content. If
|
|
@scheme[tag] is @scheme[#f], a tag string is generated automatically
|
|
from the content. The tag string is combined with the symbol
|
|
@scheme['part] to form the full tag.
|
|
|
|
A style of @scheme['toc] causes sub-sections to be generated as
|
|
separate pages in multi-page HTML output. A style of @scheme['index]
|
|
indicates an index section whose body is rendered in two columns for
|
|
Latex output.
|
|
|
|
The @scheme[vers] argument is propagated to the @scheme[title-decl]
|
|
structure.
|
|
|
|
The section title is automatically indexed by
|
|
@scheme[decode-part]. For the index key, a leading ``A'', ``An'', or
|
|
``The'' (followed by whitespace) is removed.}
|
|
|
|
|
|
@def-section-like[section part-start?]{ Like @scheme[title], but

generates a @scheme[part-start] of depth @scheme[0] to be by

@scheme[decode] or @scheme[decode-part].}
|

@def-section-like[subsection part-start?]{ Like @scheme[section], but

@def-section-like[subsubsection part-start?]{ Like @scheme[section], but

generates a @scheme[part-start] of depth @scheme[2].}
|
|
|
|
@def-section-like[subsubsub*section paragraph?]{ Similar to
|
|
@scheme[section], but merely generates a paragraph that looks like an
|
|
unnumbered section heading (for when the nesting gets too deep to
|
|
include in a table of contents).}
|
|
|
|
@defproc[(itemize [itm (or/c whitespace? an-item?)] ...) itemization?]{
|
|
|
|
Constructs an itemization given a sequence of items constructed by
|
|
@scheme[item]. Whitespace strings among the @scheme[itm]s are
|
|
ignored.
|
|
|
|
}
|
|
|
|
@defproc[(item [pre-flow any/c] ...) item?]{
|
|
|
|
Creates an item for use with @scheme[itemize]. The @tech{decode}d
|
|
@scheme[pre-flow] (i.e., parsed with @scheme[decode-flow]) is the item
|
|
content.}
|
|
|
|
|
|
@defproc[(item? [v any/c]) boolean?]{
|
|
|
|
Returns @scheme[#t] if @scheme[v] is an item produced by
|
|
@scheme[item], @scheme[#f] otherwise.}
|
|
|
|
|
|
@defform[(include-section module-path)]{ Requires @scheme[module-path]
|
|
and returns its @scheme[doc] export (without making any imports
|
|
visible to the enclosing context). Since this form expands to
|
|
@scheme[require], it must be used in a module or top-level context.}

|
Creates an index element given a plain-text string---or list of
|
|
strings for a hierarchy, such as @scheme['("strings" "plain")] for a
|
|
``plain'' entry until a more general ``strings'' entry. The strings
|

also serve as the text to render in the index. The @tech{decode}d

@scheme[pre-content] is the text to appear inline as the index

target.}

Like @scheme[index], except that @scheme[words] must be a list, and

the list of contents render in the index (in parallel to

@scheme[words]) is supplied as @scheme[word-contents].

@defproc[(as-index [pre-content any/c] ...)

index-element?]{

@scheme[content->string] on the @tech{decode}d @scheme[pre-content].}
|

@defproc[(section-index [word string?] ...)
|
|
part-index-decl?]{
|
|
|
|
Creates a @scheme[part-index-decl] to be associated with the enclosing

section by @scheme[decode]. The @scheme[word]s serve as both the keys
|
|
and as the rendered forms of the keys.}

@defproc[(index-section [#:tag tag (or/c false/c string?) "doc-index"])

part?]{

Produces a part that shows the index the enclosing document. The

optional @scheme[tag] argument is used as the index section's tag.}

@section{Tables of Contents}
|

@defproc[(table-of-contents) delayed-flow-element?]{
|
|
|
|
Returns a delayed flow element that expands to a table of contents for
|
|
the enclosing section. For LaTeX output, however, the table of
|
|
contents currently spans the entire enclosing document.}
|
|
|
|

@defproc[(local-table-of-contents) delayed-flow-element?]{

Returns a delayed flow element that may expand to a table of contents

for the enclosing section, depending on the output type. For
|
|
multi-page HTML output, the flow element is a table of contents; for
|
|
Latex output, the flow element is empty.}
