Projects using Noweb
This page contains a list of projects that use the noweb literate-programming tool.
- Kiyoshi Akima
uses noweb to improve his own understanding of his programs,
even for programs that probably will never be published, strictly
for internal, exploratory, experimental use.
- Rob Arthan and his colleages
at Lemma 1 use noweb
for general purpose programming in C, C++, ML and what have you.
They also find that noweb
is ideal for managing Java source. This code involves several packages, most
of which contain many tiny (<10 line) classes, and the compiler
requires that each class be in a separate Java source file.
Noweb of course allows these to be combined, plus documentation,
the bee's knees for solving this problem.
- Fco. Ballesteros is using noweb to write Off, a distributed
- Daniel Bastos
uses noweb to help himself
understand his own programs and because he agrees with Knuth that
a computer program is a literary work and should
be written for humans to read.

uses noweb with Microsoft Visual C++ 4.2.
added a Tool to the IDE that launches Noweave with the current file and
standard options, such as -html. Similarly for Notangle. When he wants
to see the work he hits, VC++ launches Noweave, and he keeps on
Adding the generated C++ file to the project lets everything

noweb to teach Computer Organization (a great way to document assembly
language) and Algorithms.
- Simon Clift
has used Noweb for
fluid dynamics and high-performance financial analysis programs with
Perl, Python, C, C++, Fortran, shell scripts and even makefiles.
Noweb (with LaTeX) enabled his last project to be fully
cross-referenced from the business case to the design documents and
through to the source code. Code was enhanced with diagrams and
equations, and mixed-language source files could group (for example) a
Python object with the Fortran code for the high performance
- Matt Craig uses noweb to teach astronomy as
well as in his astronomy research.
He came up with a cute trick for
maintaining loop nests.
- John Cummings
has been using noweb to write a suite of programs
to do partial-wave analysis of particle-physics data.
He finds that noweb is easy to use and works well, and he really
appreciates the language-independence.
- Johannes Derwisch
uses noweb to weave documentation into
Fernández used noweb to build UnQL a
query language for structured data.
Some people who got her source code were thrilled because ``nobody had
ever given them documented code before.''

in his teaching—students in his programming course use noweb to
write their homework.
- Chris Fraser and Dave Hanson used noweb to write lcc
retargetable C compiler (and the associated book).

You can add noweave to the Tools menu to get HTML.
- Lou Glassy
finds that literate programming debugging time for his
programs. He doesn't find that it takes longer to write a literate
program, but he does find that the program which emerges is (a)
probably correct and (b) easy to debug if it is not correct.
Lou has recently given a seminar on literate
programming, with examples.
- Carl Gregory
has using noweb since 1993 at Tipton Cole & Company, primarily
for continuing applications in Paradox for DOS, Microsoft Access, Visual
BASIC, and HTML, all running under Windows 95.

Declarative Duck models for constraint programming in DONALD,
and over 400 pages of structured documentation in bash and gawk.
- Mark Lunt uses noweb for hobby projects
(e.g., a sequencer for Linux). He writes
``When you only get to work on
something every 6 months or so, it is very useful to be reminded exactly why
you did things when you first wrote them. I also use noweb format files in my
work as a statistician: the documentation chunks will become a paper, the code
chunks perform the analyses that produce the results the paper is based on.''
- Barry MacKichan is
developing an XML back
end for noweb. As of May, 1998, it is work in progress and not polished.
(A trip to the bookstore suggests that XML
is the latest hot thing.)

uses noweb for the usual programming type stuff, but also for creating
input for scientific programs. He uses noweb to create readable (by
humans) input which is then tangled into what the program actually
- Volker Strumpen
uses noweb to write the source code of the

documentation was extremely useful because of the mathematical
- Thomas Tensi
a literate-programming tool for the Psion handheld.
His tool is based on Noweb.
- Terry Therneau of the Division of Biostatistics at the Mayo Clinic
uses noweb to implement
mixed effects Cox models. The algorithm is mathematically subtle, and
it also requires sparse matrix concepts for reasonable speed, so
standard comments were not enough.

and documenting simulation programs in Simscript, ModSim and a new Java
Since the general form of a simulation program is reasonably standard
(they all consist of collections of processes and resources, entities
and queues, or events), they have found it useful to have a template noweb
file which helps us in the program development as well. The
philosophy is always to have a running simulation program from the
beginning of the project.
