This is no real problem because no one is supposed +%D to read and understand the files generated by \CWEB. The +%D standard macros are meant for \PLAIN\ \TEX\ users. In +%D \CONTEXT\ and other macro packages however, there is a +%D potential conflict with format specific or user defined +%D commands. Furthermore, the \CWEB\ macros implement their own +%D output routines. When integrating \CWEB\ documents in +%D another environment, the \CWEB\ specific macros have to be +%D made local. The first part of this module is dedicated to +%D this feature. +%D +%D Instead of using \type{\def} and \type{\let} for defining +%D macros, we use: +%D +%D \starttyping +%D \defCEBmacro arguments {meaning} +%D \letCEBmacro arguments {meaning} +%D \stoptyping +%D +%D \CWEB files contain implicit calls to macros that generate +%D the table of contents, the lists of sections and the index. +%D Because we want to be much more flexible, we implemented our +%D own alternatives, and therefore have to bypass the original +%D ones. The next macro is used for defining these obsolete +%D \CWEB\ macros. The dummies take care of arguments. +%D +%D \starttyping +%D \defCEBdummy arguments {meaning} +%D \stoptyping +%D +%D The list of \CWEB\ specific macro names is saved in a +%D \TOKENLIST. This serves two purposes. First it enables us to +%D activate the \CWEB\ macros, which are saved under a +%D different name, second it can be used to temporary restore +%D the meanings, for instance when the output routine builds +%D the page. + +\newtoks\CWEBmacros + +%D Activating and deactivating is done by means of: +%D +%D \starttyping +%D \activateCWEB +%D \deactivateCWEB +%D \stoptyping +%D +%D Which are implemented as: + +\def\activateCWEB% + {\let\doCWEB=\activateCWEBmacro + \the\CWEBmacros} + +\def\deactivateCWEB% + {\let\doCWEB=\deactivateCWEBmacro + \the\CWEBmacros} + +%D The three definition macros append the name of the macro to +%D the list.

So I decided to stick to +%D the method as just described. + +%D Now we're ready for the real job. What follows is a partial +%D adaption of the file \type{cwebmac.tex}, version 3.1, dated +%D September 1994 and written by Levy and Knuth. When possible +%D we kept the original meaning, but we've granted ourselves +%D the freedom to reformat the macro's for readibility. +%D +%D We'll only present the macros we actually use. The source +%D however contains the original implementation. + +% standard macros for CWEB listings (in addition to plain.tex) +% Version 3.1 --- September 1994. +% +% \ifx\documentstyle\undefined\else\endinput\fi % LaTeX will use other macros +% +% \xdef\fmtversion{\fmtversion+CWEB3.1} + +%D \macros{.}{} +%D +%D \CWEBquote preserve a way to get the dot accent (all +%D other accents will still work as usual). + +\letCWEBmacro\: = \. + +% \parskip = 0pt % no stretch between paragraphs +% \parindent = 1em % for paragraphs and for the first line of C text + +% \font\ninerm = cmr9 +% \let\mc = \ninerm % medium caps +% \font\eightrm = cmr8 +% \let\sc = \eightrm % small caps (NOT a caps-and-small-caps font) +% \let\mainfont = \tenrm +% \let\cmntfont = \tenrm +% \font\tenss = cmss10 +% \let\cmntfont = \tenss % alternative comment font +% \font\titlefont = cmr7 scaled \magstep4 % title on the contents page +% \font\ttitlefont = cmtt10 scaled \magstep2 % typewriter type in title +% \font\tentex = cmtex10 % TeX extended character set (used in strings) +% \fontextraspace\tentex = 0pt % no double space after sentences + +%D \macros{mc,sc,cmntfont,eightrm}{} +%D +%D The naming of the fonts in in line with those in \PLAIN\ +%D \TEX.
