D. P. Story (dpstory at acrotex dot net) +% +% Comment.sty version 3.2, August 1997 +% selectively in/exclude pieces of text: the user can define new +% comment versions, and each is controlled separately. +% Special comments can be defined where the user specifies the +% action that is to be taken with each comment line. +% +% This style can be used with plain TeX or LaTeX, and probably +% most other packages too. +% +% Author +% Victor Eijkhout +% Department of Mathematics +% University of California +% 405 Hilgard Ave, MS 6363 +% Los Angeles, CA 90034 +% USA +% +% eijkhout@math.ucla.edu +% +% Usage: all text included in between +% \comment ... \endcomment +% or \begin{comment} ... \end{comment} +% is discarded. +% The opening and closing commands should appear on a line +% of their own. No starting spaces, nothing after it. +% This environment should work with arbitrary amounts +% of comment. +% +% Other `comment' environments are defined by +% and are selected/deselected with +% \includecomment{versiona} +% \excludecoment{versionb} +% +% These environments are used as +% \versiona ... \endversiona +% or \begin{versiona} ... \end{versiona} +% with the opening and closing commands again on a line of +% their own. +% +% LaTeX users note: for an included comment, the +% \begin and \end lines act as if they don't exist. +% In particular, assignments &c are not local. +% +% Special comments are defined as +% \specialcomment{name}{before commands}{after commands} +% where the second and third arguments are executed before +% and after each comment block. +% By defining a control sequence +% \Thiscomment##1{...} in the before commands the user can +% specify what is to be done with each comment line. +% To keep definitions &c local, you can include \begingroup +% in the `before commands' and \endgroup in the `after commands'. +% +% Basic approach: +% to comment something out, scoop up every line in verbatim mode +% as macro argument, then throw it away. +% For inclusions, in LaTeX the block is written out to +% a file "comment.cut", which is then included. +% In plain TeX (and other formats) both the opening and +% closing commands are defined as noop. +% +% Trick for short in/exclude macros (\maybe{this snippet}): +%\includeversion{cond} +%\newcommand{\maybe}[1]{} +%\begin{cond} +%\renewcommand{\maybe}[1]{#1} +%\end{cond} +% +% Changes in version 3.1 +% - updated author's address +% - cleaned up some code +% - trailing contents on \begin{env} line is always discarded +% even if you've done \includecomment{env} +% - comments no longer define grouping!! you can even +% \includecomment{env} +% \begin{env} +% \begin{itemize} +% \end{env} +% Isn't that something ... +% - included comments are written to file and input again. +% Changes in 3.2 +% - \specialcomment brought up to date (thanks to Ivo Welch). +% +\def\makeinnocent#1{\catcode`#1=12 } +\def\csarg#1#2{\expandafter#1\csname#2\endcsname} +\def\latexname{lplain}\def\latexename{LaTeX2e} +\newwrite\CommentStream + +\def\ProcessComment#1{\begingroup + \def\CurrentComment{#1}% + \let\do\makeinnocent \dospecials + \makeinnocent\^^L% and whatever other special cases + \endlinechar`\^^M \catcode`\^^M=12 \fxComment} +{\catcode`\^^M=12 \endlinechar=-1 % + \gdef\fxComment#1^^M{\xComment} + \gdef\xComment#1^^M{\def\test{#1} + \csarg\ifx{End\CurrentComment Test}\test + \edef\next{\noexpand\EndOfComment{\CurrentComment}}% + \else \ThisComment{#1}\let\next\xComment + \fi \next} +} + +% 3.1 change: in LaTeX and LaTeX2e prevent grouping +\if 0% +\ifx\fmtname\latexename + 0% +\else \ifx\fmtname\latexname + 0% + \else + 1% +\fi \fi +%%%% +%%%% definitions for LaTeX +%%%% +\edef\restoreat{\catcode\noexpand`\noexpand\@=\the\catcode`\@\relax} +\makeatletter +\def\AfterIncludedComment + {\immediate\closeout\CommentStream + \input comment.cut + }% +\def\WriteCommentLine#1{\immediate\write\CommentStream{#1}} +\def\BeforeIncludedComment{\immediate\openout\CommentStream=comment.cut + \let\ThisComment\WriteCommentLine} +\def\includecomment + #1{\message{Include comment '#1'}% + \csarg\let{After#1Comment}\AfterIncludedComment + \csarg\def{#1}{\BeforeIncludedComment + \ProcessComment{#1}}% + \CommentEndDef{#1}} +\long\def\specialcomment + #1#2#3{\message{Special comment '#1'}% + \csarg\def{After#1Comment}{#2\AfterIncludedComment#3}% + \csarg\def{#1}{\BeforeIncludedComment + \ProcessComment{#1}}% + \CommentEndDef{#1}} +\restoreat +\else +%%%% +%%%%plain TeX and other formats +%%%% +\def\includecomment + #1{\message{Including comment '#1'}% + \csarg\def{#1}{}% + \csarg\def{end#1}{}} +\long\def\specialcomment + #1#2#3{\message{Special comment '#1'}% + \csarg\def{#1}{\def\ThisComment{}\def\AfterComment{#3}#2% + \ProcessComment{#1}}% + \CommentEndDef{#1}} +\fi + +%%%% +%%%% general definition of skipped comment +%%%% +\def\excludecomment + #1{\message{Excluding comment '#1'}% + \csarg\def{#1}{\let\AfterComment\relax + \def\ThisComment####1{}\ProcessComment{#1}}% + \CommentEndDef{#1}} + +\if 0% +\ifx\fmtname\latexename + 0% +\else \ifx\fmtname\latexname + 0% + \else + 1% +\fi \fi +% latex & latex2e: +\def\EndOfComment#1{\endgroup\end{#1}% + \csname After#1Comment\endcsname} +\def\CommentEndDef#1{{\escapechar=-1\relax + \csarg\xdef{End#1Test}{\string\\end\string\{#1\string\}}% + }} +\else +% plain & other +\def\EndOfComment#1{\endgroup\AfterComment} +\def\CommentEndDef#1{{\escapechar=-1\relax + \csarg\xdef{End#1Test}{\string\\end#1}% + }} +\fi + +\excludecomment{comment} + +\endinput |
