NOWEB(1) General Commands Manual NOWEB(1)NAME
noweb - a simple literate-programming tool
SYNOPSIS
noweb [-t] [-o] [-Lformat] [-markup parser] [file] ...
DESCRIPTION
Noweb is a literate-programming tool like FunnelWEB or nuweb, only simpler. A noweb file contains program source code interleaved with
documentation. When noweb is invoked, it writes the program source code to the output files mentioned in the noweb file, and it writes a
TeX file for typeset documentation.
The noweb(1) command is for people who don't like reading man pages or who are switching from nuweb. To get the most out of noweb, use
notangle(1) and noweave(1) instead.
FORMAT OF NOWEB FILES
A noweb file is a sequence of chunks, which may appear in any order. A chunk may contain code or documentation. Documentation chunks
begin with a line that starts with an at sign (@) followed by a space or newline. They have no names. Code chunks begin with
<<chunk name>>=
on a line by itself. The double left angle bracket (<<) must be in the first column. Chunks are terminated by the beginning of another
chunk, or by end of file. If the first line in the file does not mark the beginning of a chunk, it is assumed to be the first line of a
documentation chunk.
Documentation chunks contain text that is copied verbatim to the TeX file (except for quoted code). noweb works with LaTeX; the first doc-
umentation chunk must contain a LaTeX documentclass command, it must contain usepackage{noweb} in the preamble, and finally it must also
contain a LaTeX egin{document} command.
Code chunks contain program source code and references to other code chunks. Several code chunks may have the same name; noweb concate-
nates their definitions to produce a single chunk, just as other literate-programming tools do. noweb looks for chunks that are defined
but not used in the source file. If the name of such a chunk contains no spaces, the chunk is an ``output file;'' noweb expands it and
writes the result onto the file of the same name. A code-chunk definition is like a macro definition; it contains references to other
chunks, which are themselves expanded, and so on. noweb's output is readable; it preserves the indentation of expanded chunks with respect
to the chunks in which they appear.
If a star (*) is appended to the name of an output file, noweb includes line-number information as specified by the -Lformat option (or for
C if no -Lformat option is given). The name itself may not contain shell metacharacters.
Code may be quoted within documentation chunks by placing double square brackets ([[...]]) around it. These double square brackets are
used to give the code special typographic treatment in the TeX file. If quoted code ends with three or more square brackets, noweb chooses
the rightmost pair, so that, for example, [[a[i]]] is parsed correctly.
In code, noweb treats unpaired double left or right angle brackets as literal << and >>. To force any such brackets, even paired brackets
or brackets in documentation, to be treated as literal, use a preceding at sign (e.g. @<<).
OPTIONS -t Suppress generation of a TeX file.
-o Suppress generation of output files.
-Lformat
Use format to format line-number information for starred output files. (If the option is omitted, a format suitable for C is used.)
format is as defined by notangle(1);
-markup parser
Use parser to parse the input file. Enables use of noweb tools on files in other formats; for example, the numarkup parser under-
stands nuweb(1) format. See nowebfilters(7) for more information. For experts only.
BUGS
Ignoring unused chunks whose names contain spaces sometimes causes problems, especially in the case when a chunk has multiple definitions
and one is misspelled; the misspelled definition will be silently ignored. noroots(1) can be used as a sanity checker to catch this sort
of mistake.
noweb is intended for users who don't want the power or the complexity of command-line options. More sophisticated users should avoid
noweb and use noweave and notangle instead. If the design were better, we could all use the same commands.
noweb requires the new version of awk. DEC nawk has a bug in that that causes problems with braces in TeX output. GNU gawk is reported to
work.
The default LaTeX pagestyles don't set the width of the boxes containing headers and footers. Since noweb code paragraphs are extra wide,
this LaTeX bug sometimes results in extra-wide headers and footers. The remedy is to redefine the relevant ps@* commands; ps@noweb in
noweb.sty can be used as an example.
