text-crossrefs: getting references to page and note numbers in Pandoc

This filters aims at extending Pandoc's cross-referencing capacities by enabling automatic references to any piece of text by either its page or, whenever it applies, its note number. It currently supports the following target formats:

• context
• docx
• latex
• odt
• opendocument

It doesn't permit to refer to references in other files: if you want to do this, use text-extrefs.

N.-B.: When opening for the first time a DOCX or ODT/Opendocument file produced by Pandoc with text-crossrefs, you probably will have to refresh the fields in order to get the correct values. In LibreOffice, press F9; in Word, a dialog box should appear when the file opens.

Usage

Basics

Mark the span of text you want to refer to later with an identifier composed of alphanumeric characters, periods, colons, underscores and hyphens:

Émile Gaboriau published [_L'Affaire Lerouge_ in
1866]{#publication}.[^1]

[^1]: It is a very [fine piece of literature]{#my-evaluation}.

[It was very popular.]{#reception}

You can refer to it using another span with class ref containing the target's identifier. If the targetted span is part of a footnote, you can refer to it either by page or by note number according to the value of the type attribute (defaults to page). For instance, this:

See [publication]{.ref} for the publication date. I gave my
opinion in [my-evaluation]{.ref type=note}, [my-evaluation]{.ref}.

will render in LaTeX output:

See p. \pageref{publication} for the publication date. I expressed
my thoughts about it in \ref{my-evaluation},
p. \pageref{my-evaluation}.

If you want to give a reference by note and page number like in the example above, you can also use the following shorthand:

[my-evaluation]{.ref type=pagenote}

You can refer to headers as well using either explicit or automatically generated identifiers (see Pandoc user’s guide).

Page ranges

You can refer to a page range like this:

If you want to know more about _L'Affaire Lerouge_, see [publication>reception]{.ref}.

The separator (here >) can be set to any string composed of characters other than alphanumeric, period, colon, underscore, hyphen and space.

In LaTeX and ConTeXt output, the page range will be printed as a simple page reference if the page numbers are identical. You can provide your own definition of the macro \tcrfpagerangeref[<prefixed?>]{<label1>}{<label2>} in the preamble. In DOCX and ODT/Opendocument output, the same result can be achieved in a word processor by the means of automatic search and replace with regular expressions.

Enumerations

Rather

Enumerations are only supported for references to page and note numbers.

Customization

The following metadata fields can be set as strings:

• tcrf-page-prefix:
  • “page” prefix;
  • defaults to p. .
• tcrf-pages-prefix:
  • “pages” prefix;
  • defaults to p. .
• tcrf-note-prefix:
  • “note” prefix;
  • defaults to n. .
• tcrf-notes-prefix:
  • “notes” prefix;
  • defaults to n. .
• tcrf-pagenote-separator:
  • the separator between the references when type is set to pagenote;
  • defaults to , .
• tcrf-pagenote-at-end:
  • the string printed at the end of a pagenote reference;
  • defaults to an empty string, can be used to achieve something like n. 3 (p. 5).
• tcrf-pagenote-order:
  • the order in which the references to note and page are printed;
  • defaults to pagefirst, can be set to notefirst.
• tcrf-references-range-separator:
  • the string used to separate two references in a reference span; can be composed of any character not authorized in an identifier other than space or tab;
  • defaults to >.
• tcrf-range-separator:
  • the string inserted between to page numbers in a range;
  • defaults to -.
• tcrf-references-enum-separator:
  • the string used to separate the elements of an enumeration in a reference span; can be composed of any character not authorized in an identifier other than space or tab;
  • defaults to ;.
• tcrf-multiple-delimiter:
  • the string inserted between two elements (but the two last ones) in an enumeration;
  • defaults to a comma followed by a space.
• tcrf-multiple-before-last:
  • the string inserted between the two last elements in an enumeration;
  • defaults to and surrounded with spaces.
• tcrf-only-explicit-labels:
  • set it to true if you want that tcrf handle only spans with class label;
  • defaults to false.
• tcrf-default-info-type:
  • default value for the type attribute (note, page or pagenote);
  • defaults to page.
• tcrf-filelabel-ref-separator:
  • only useful in conjunction with the text-exrefs filter;
  • separator between external files' labels and references;
  • defaults to ::.

Compatibility with other filters

Text-crossrefs must be run after all other filters that can create, delete or move footnotes, like citeproc.

In order to give and identifier to a note produced by a citation inside square brackets, the span should not include the citation key, the locator or the ; delimiter. If it is placed immediatly after the locator, this should be surrounded by curly brackets. So this should work:

[@Jones1973, p. 5-70; @Doe2004[]{#jones-doe}]

[@Jones1973, p. 5-70; [it was elaborated upon]{#further-elaboration} by @Doe2004]

[@Jones1973, {p. 5-70}[]{#ref-to-jones}; @Doe2004]

not that:

[[@Jones1973, p. 5-70]{#ref-to-jones}; @Doe2004]

[[@Jones1973, p. 5-70; @Doe2004]{#jones-doe}]

[@Jones1973, p. 5-70[]{#ref-to-jones}; @Doe2004]

You can set classes and attributes to your spans other than those defined by text-crossrefs (for instance [some text]{#to-be-referred-to .highlighted color=red} or [reference]{.ref color=red}). No span is removed.

Text-crossrefs is fully compatible with text-extrefs. Whenever possible, when a metadata is not set for text-extrefs, its value is taken from its text-crossrefs equivalent, so that you don't need to duplicate similar variables.
