 NOWEB(7) Miscellaneous Information Manual NOWEB(7)

## NAME

nowebstyle - LaTeX package for noweb

## SYNOPSIS

\usepackage{noweb}

## DESCRIPTION

When noweave generates code for LaTeX, the noweb package is required. In addition to the necessary arcana, it defines a webcode environment in which you can place fragments of code, and in which only backslash and curly braces have their special meanings; all other characters are taken literally. It also defines a noweb pagestyle. Finally, it defines a \noweboptions{...} command that can be used to tinker with the appearance of the output. Options are separated by commas and include:
margintag
Put the sub-page number (tag) of each code-chunk definition in the left margin. (Default)
nomargintag
Don't use margin tags.
shift
Shift text to the left so that long code lines won't extend off the right-hand side of the page.
smallcode
Set code in LaTeX \small font instead of \normalsize. Similar options exist for all the LaTeX size-changing commands.
longxref, shortxref, noxref
Choose a style for chunk cross-reference. Long style uses small paragraphs after each chunk, as in Knuth. Short style uses symbols on the definition line, as in Hanson. noxref provides no chunk cross-reference. Defaults to shortxref.
alphasubpage, numsubpage, nosubpage
Number chunks by the number of the page on which they appear, followed by an alphabetic (numeric, not used) sub-page'' indicator. Defaults to alphasubpage. nosubpage implies nomargintag.
webnumbering
Number chunks consecutively, in WEB style, instead of using sub-page numbers.
subscriptidents, nosubscriptidents, hyperidents, nohyperidents
Controls subscripting of identifiers in code, including quoted code. Selecting subscriptidents means an identifier appearing in a code chunk (or in quoted code within a documentation chunk) will be subscripted with the chunk number of its definition. hyperidents means such identifiers will be hyperlinked to their definitions, provided of course that a hypertext package like hyperref is loaded. nosubscriptidents and nohyperidents are equivalent, and they turn off such markings. The default is hyperidents.
subscriptquotedidents, nosubscriptquotedidents, hyperquotedidents, nohyperquotedidents
Controls linking of identifiers as above, but applies only to uses of identifiers in quoted code.
hideunuseddefs
Omit defined but unused identifiers from the local identifier cross-reference (Preston Briggs).
noidentxref
Omit the local identifier cross-reference which follows each code chunk.
externalindex
Use an index generated with noindex(1) (q.v.).
longchunks
When expanding \nowebchunks, show page numbers of definitions and uses of each chunk.
english, french, german, portuges
Write cross-reference information in the language specified. Defaults to english.

## CONTROL SEQUENCES

The noweb package describes a gazillion special control sequences. Only a few are listed here.
\nextchunklabel{l}
Associates label l with the sub-page reference of the next code chunk. Can be used in for concise chunk cross-reference with, e.g., chunk~\subpageref{l}.
\nwanchorto{URL}{anchor text}
Creates a link to the given URL with the given anchor text. Implemented in latex(1) using footnotes, but sl2h(1) translates this to <a href=URL>anchor text</a>
\nwanchorname{name}{anchor text}
Creates an anchor point for a hyperlink. Implemented in latex(1) using \label , but sl2h(1) translates this to <a name=name>anchor text</a>
\ifhtml ... \fi
Text between \ifhtml and \fi is ignored by latex(1), but sl2h(1) and the l2h noweb filter translate the text into HTML.
