<h1>Noweb example programs</h1>
All but one of
these examples have had their documentation parts converted automatically
from LaTeX to HTML.
(Can you tell which one?)
Except for <a href=breakmodel.html>breakmodel</a>,
each example file is a fragment of a larger
program.
<p>
The typical command line used to create one of these documents is:
<pre>
noweave -filter l2h -index -autodefs c -html compress.nw > compress.html
</pre>
for various values of <tt>c</tt> :-)
<p>
The example programs are:
<dl>
<dt><a href=breakmodel.html>breakmodel</a><dd>
A formal model of breakpoints using the
Promela modeling language.
<dt><a href=compress.html>compress</a><dd>
A library that modifies the <t>open</t>, <t>close</t>, <t>read</t>,
and <t>write</t> system calls (along with some others) to
transparently read and write files in Unix <t>compress</t> format.

<dt><a href=dag.html>dag</a><dd>
Fragment of an <a href=http://www.cs.arizona.edu/icon/>Icon</a>
program that compiles
patterns into decision-tree pattern-matching
code. tree.nw builds the decision trees;
dag.nw turns them into dags.
<dt><a href=graphs.html>graphs</a><dd>
Several graphs written in
<a href=http://www.cs.utk.edu/~plank/plank/jgraph/jgraph.html>jgraph</a>.
<dt><a href=mipscoder.html>mipscoder</a><dd>
Part of the original MIPS code generator from
Standard ML of New Jersey. Written in Standard ML.
<dt><a href=primes.html>primes</a><dd>
noweb version of DEK's original prime-number program.
I got tired of typing and never entered all the text.
<dt><a href=scanner.html>scanner</a><dd>
Part of a student compiler project. Includes
C code and lex and yacc specifications, all in
a single file.
<dt><a href=solver.html>solver</a><dd>
An equation solver, published in <em>Software---Practice & Experience</em>.
The <A href=/~nr/pubs/solver.ps>PostScript</a> is probably easier to read.
<dt><a href=test.html>test</a><dd>
A simple test file.
<dt><a href=tree.html>tree</a><dd>
Fragment of an <a href=http://www.cs.arizona.edu/icon/>Icon</a>
program that compiles
patterns into decision-tree pattern-matching
code. tree.nw builds the decision trees;
dag.nw turns them into dags.
<dt><a href=wc.html>wc</a><dd>
An re-implementation of the example word-count program from Don
Knuth's book on literate programming.
This example is as exact a copy as possible; no
attempt was made to improve the code.
<a href="wcni.html">Here</a> is a version without identifier
cross-reference, which gives it a cleaner look.
<a href="wc.nw.html">Here</a> you can see a plain-text
rendering of the <tt>noweb</tt> source.
