2014年12月12日 · Dr. Knuth's original WEB system was for Pascal, but he and Silvio Levy converted it to C, producing CWEB, which you can read about in the cwebman manual described above. Norman Ramsey developed the SPIDER system to allow the WEB concept to be ported theoretically to any combination of a programming language and formatting/display language.

2014年11月18日 · While writing a CWEB program I wanted to write a comment like this: @ If the option \.{-a} has been specified, the output files need to be opened in append-only mode. Our program should also create the output file, thus the flags with which we open the output file are either |O_RDONLY|O_CREAT|O_APPEND| or |O_RDONLY|O_CREAT| as explained above.

2019年2月19日 · I'm interested in using CWEB with LaTeX on Windows. Today I discovered my MikTeX installation comes with two interesting programs, cweave and ctangle.

2016年1月29日 · CWEB is built on Plain TeX. It loads its own macro package (cwebmac.tex) in addition. If you want Unicode support you could try compiling with xetex (not xelatex), but I haven't tested this.

2019年2月19日 · I'm using egreg's code to use UTF-8 in Plain TeX so I can use Donald Knuth and Silvio Levy's CWEB. However, not every TeX font supports foreign language characters such as \"{y} or ç or ã.

2017年6月29日 · This is documented in the CWEB manual (which you can open by invoking texdoc cweb which opens a DVI file, or read as PDF online), in Appendix C: How to use CWEB macros (page 25), point 4. The trick is that after setting any of \pagewidth (default 6.5in), \pageheight (default 8.7in) or \fullpageheight (default 9in), you need to say \setpage:

2021年4月12日 · When I use NULL in a CWEB document, it is typeset as Λ (\Lambda) in the cweave output. Indeed, I see \let\NULL=\Lambda in cwebmac.tex. Why is this the default? I was very puzzled when I first looked at the symbol--I realized that it meant NULL only because of the context, not by the symbol itself.

2015年4月11日 · I would like to use eplain macros in a CWEB program, but eplain and cwebmac seem to conflict in their PDF support. Specifically, they both define \ifpdf. The cweave program turns the code below (mwe.w) into a .tex file with \input cwebmac at the top.
