4.7 Compatibility Libraries

4.7.1 Compatibility Structures And Processing

The scribble/struct compatibility library mostly re-exports scribble/core, but using some different names (e.g., blockquote instead of nested-flow).

The following structure types and functions are re-exported directly:

collect-info resolve-info tag? block?
delayed-block collected-info delayed-element
part-relative-element collect-info-parents
collect-element render-element generated-tag
tag-key content->string element->string
block-width element-width
info-key? part-collected-info collect-put!
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:

part paragraph table itemization compound-paragraph
element toc-element target-element toc-target-element toc-target2-element
page-target-element redirect-target-element link-element
index-element

Several additional compatibility functions and structure types are also exported.

procedure
(make-part tag-prefix
tags
title-content
style
to-collect
blocks
parts) → part?
  tag-prefix : (or/c false/c string?)
  tags : (listof tag?)
  title-content : (or/c false/c list?)
  style : any/c
  to-collect : list?
  blocks : (listof block?)
  parts : (listof part?)

For backward compatibility. Compared to the normal constructor for part, parses style to convert old formats to the current one. Also, if title-content is a list with a single item, the item by itself is stored in the resulting part.

procedure
(part-flow p) → (listof block?)
p : part?

For backward compatibility. An alias for part-blocks.

procedure
(part-title-content p) → list?
p : part?

For backward compatibility. Like the normal selector, but if the result would not be a list, it is coerced to one.

procedure
(make-versioned-part tag-prefix
tags
title-content
style
to-collect
blocks
parts
version) → part?
  tag-prefix : (or/c false/c string?)
  tags : (listof tag?)
  title-content : (or/c false/c list?)
  style : any/c
  to-collect : list?
  blocks : (listof block?)
  parts : (listof part?)
  version : string?
procedure
(versioned-part? v) → boolean?
  v : any/c

For backward compatibility. Like make-part, but adds a the document-version style property using the given version. The versioned-part? predicate recognizes a part with a document-version property.

procedure
(make-unnumbered-part tag-prefix
tags
title-content
style
to-collect
blocks
parts) → part?
  tag-prefix : (or/c false/c string?)
  tags : (listof tag?)
  title-content : (or/c false/c list?)
  style : any/c
  to-collect : list?
  blocks : (listof block?)
  parts : (listof part?)
procedure
(unnumbered-part? v) → boolean?
  v : any/c

For backward compatibility. Like make-part, but adds the 'unnumbered style property. The unnumbered-part? predicate recognizes a part with the 'unnumbered property.

procedure
(make-paragraph content) → paragraph?
content : list?

For backward compatibility. Compared to the normal constructor for paragraph, omits a style argument. Also, if content is a list containing a single item, the item by itself is stored in the resulting paragraph.

procedure
(paragraph-content p) → list?
p : paragraph?

For backward compatibility. Like the normal selector, but if the result would not be a list, it is coerced to one.

procedure
(make-styled-paragraph content style) → paragraph?
  content : list?
  style : any/c
procedure
(styled-paragraph? v) → boolean?
  v : any/c
procedure
(styled-paragraph-style p) → style?
  p : paragraph?

For backward compatibility. Compared to the normal constructor for paragraph, parses style to convert old formats to the current one. The styled-paragraph? predicate and styled-paragraph-style accessor are aliases for paragraph? and paragraph-style.

procedure
(make-omitable-paragraph content) → paragraph?
content : list?
procedure
(omitable-paragraph? v) → boolean?
v : any/c

For backward compatibility. Like make-paragraph, but adds the 'omitable style property. The omitable-paragraph? predicate checks for a paragraph with the property.

procedure
(make-table style blocksss) → table?
style : any/c
blocksss : (listof (listof (or/c (listof block?) (one-of/c 'cont))))

For backward compatibility. Compared to the normal constructor for table, the style is converted, and each cell has a list of blocks instead of a single block. If any such list has multiple blocks, they are combined into a nested-flow.

procedure
(table-flowss table)
→ (listof (listof (or/c (listof block?) (one-of/c 'cont))))
table : table?

For backward compatibility. Like table-blockss, but adds a list wrapper to be consistent with make-table.

procedure
(make-itemization blockss) → itemization?
blockss : (listof (listof block?))

For backward compatibility. Compared to the normal constructor for itemization, omits a style argument.

procedure
(make-styled-itemization style blockss) → itemization?
  style : any/c
  blockss : (listof (listof block?))
procedure
(styled-itemization? v) → boolean?
  v : any/c
procedure
(styled-itemization-style i) → style?
  i : itemization?

For backward compatibility. Compared to the normal constructor for itemization, parses style to convert old formats to the current one. The styled-itemization? predicate is an alias for itemization?, and styled-itemization-style is an alias for itemization-style.

procedure
(make-blockquote style blocks) → nested-flow?
style : any/c
blocks : (listof block?)

For backward compatibility. Like make-nested-flow, but style is parsed to the current format.

procedure
(make-auxiliary-table style blocksss) → table?
  style : any/c
  blocksss : (listof (listof (or/c (listof block?) (one-of/c 'cont))))
procedure
(auxiliary-table? v) → boolean?
  v : any/c

For backward compatibility. Like make-table, but adds the 'aux style property. The auxiliary-table? predicate recognizes tables with the 'aux property.

procedure
(make-compound-paragraph style blocks) → compound-paragraph?
style : any/c
blocks : (listof block?)

For backward compatibility. Compared to the normal constructor for compound-paragraph, parses style to convert old formats to the current one.

procedure
(make-element style content) → element?
  style : any/c
  content : list?
procedure
(make-toc-element style content toc-content) → toc-element?
  style : any/c
  content : list?
  toc-content : list?
procedure
(make-target-element style content tag) → target-element?
  style : any/c
  content : list?
  tag : tag?
procedure
(make-toc-target-element style content tag) → toc-target-element?
  style : any/c
  content : list?
  tag : tag?
procedure
(make-toc-target2-element style
content
tag
toc-content) → toc-target2-element?
  style : any/c
  content : list?
  tag : tag?
  toc-content : content?
procedure
(make-page-target-element style content tag)
→ page-target-element?
  style : any/c
  content : list?
  tag : tag?
procedure
(make-redirect-target-element style
content
tag
alt-path
alt-anchor)
→ redirect-target-element?
  style : any/c
  content : list?
  tag : tag?
  alt-path : path-string?
  alt-anchor : string?
procedure
(make-link-element style content tag) → link-element?
  style : any/c
  content : list?
  tag : tag?
procedure
(make-index-element style
content
tag
plain-seq
entry-seq
desc) → index-element?
  style : any/c
  content : list?
  tag : tag?
  plain-seq : (and/c pair? (listof string?))
  entry-seq : list?
  desc : any/c

For backward compatibility. Compared to the normal constructors, parses style to convert old formats to the current one.

procedure
(element? v) → boolean?
  v : any/c
procedure
(element-content e) → list?
  e : element?
procedure
(element-style e) → element-style?
  e : element?

For backward compatibility. A content list is treated as an element by these functions, and the result of element-content is always a list.

procedure
(make-aux-element style content) → element?
style : any/c
content : list?

For backward compatibility. Like make-element, but adds the 'aux style property.

procedure
(make-hover-element style content text) → element?
  style : any/c
  content : list?
  text : string?

For backward compatibility. Like make-element, but adds hover-property containing text to the element’s style.

procedure
(make-script-element style
content
type
script) → element?
  style : any/c
  content : list?
  type : string?
  script : (or/c path-string? (listof string?))

For backward compatibility. Like make-element, but adds script-property containing type and script to the element’s style.

struct
(struct with-attributes (style assoc)
    #:extra-constructor-name make-with-attributes)
  style : any/c
  assoc : (listof (cons/c symbol? string?))

For backward compatibility. Used for an element’s style to combine a base style with arbitrary HTML attributes. When the style field is itself an instance of with-attributes, its content is automatically flattened into the enclosing with-attributes when it is used (when, e.g., rendering an element or paragraph).

struct
(struct target-url (addr style)
    #:extra-constructor-name make-target-url)
  addr : path-string?
  style : any/c

For backward compatibility. Used as a style for an element. The style at this layer is a style for the hyperlink.

struct
(struct image-file (path scale)
    #:extra-constructor-name make-image-file)
   path :
(or/c path-string?
      (cons/c 'collects (listof bytes?)))
  scale : real?

For backward compatibility. Used as a style for an element to inline an image. The path field can be a result of path->main-collects-relative.

procedure
(element->string element) → string?
  element : content?
(element->string element renderer p info) → string?
  element : content?
  renderer : any/c
  p : part?
  info : resolve-info?

For backward compatibility. An alias for content->string.

4.7.2 Compatibility Basic Functions

(require scribble/basic)

package: scribble-lib

The scribble/basic compatibility library mostly just re-exports scribble/base.

procedure
(span-class style-name pre-content ...) → element?
style-name : string?
pre-content : any/c

For backward compatibility. Wraps the decoded pre-content as an element with style style-name.

procedure
(itemize itm ... [#:style style]) → itemization?
itm : (or/c whitespace? an-item?)
style : (or/c style? string? symbol? #f) = #f

For backward compatibility. Like itemlist, but whitespace strings among the itms are ignored.
