Welcome to “All Things WEB” in TeX Live.
Here you find the documented source code of all major
WEB and CWEB programs in readable format. With
the exception of XeTeX, all documents are in the
HINT format and can be viewed with the
hintview program, available from the HINT homepage.
The NAMED entries represent the unmodified base sources
as written by their respective authors, the attached chg
links point to only the changed sections (or modules) as applied for
release in the TeX Live distribution, so you may want to study these
pairs in parallel. Care has been taken to keep the section numbering
intact.
Although not all the programs presented here are written or maintained by Donald Knuth, it is more convenient for everything to be collected in one place for reading and searching. And they all stem from the system that Knuth created.
Note that all WEB programs are mogrified from Pascal
code to C code before compilation, so further modifications and
amendments will occur for the real thing, i.e., the production of the
executable WEB programs. (The CWEB programs do
not require these extra modifications, they get linked directly to the
external runtime environment.)
If you believe to have found anything that remains technically, historically, typographically, or politically incorrect in any of these files, please feel free to report bugs in TeX and friends or contact the maintainer of this collection directly.
