Has anyone written a "comment" environment for LaTeX? The text
between "\begin{comment}" and "\end{comment}" would not be typeset by
LaTeX.
Thanks for any and all help,
Dan

I got this from Ed Wang a while ago... works for me.

I've seen this in several places:
command:
\long\def\comment#1{}
use:
\comment{ ignored text
ignored text
ignored text

ignored text

The following simple macro will do it (thanks to Martin Carroll):
\newcommand{\comment}[1]{}

I'm not sure about all the \catcode stuff, but my intent was to make the argument as small as possible by turning most of the characters into comment characters. I tried this with the entire latex.tex file between \begin{comment} and \end{comment} and it worked ok (i.e. nothing was printed). Without the \catcode stuff I overflowed TeX's memory.

Basically it sets the comment in italics in narrow margins for drafts but ignores it for polished versions. It decides you a producing a draft if you have the overfull marker set, the draft style option does this. % comments - there are either ignored or set as a 'setcomment' % depending on whether the draft option was selected. \ifdim \overfullrule =0pt \def\comment{\@swallowall} \else\def\comment{\setcomment} \fi \ifdim \overfullrule =0pt \def\endcomment{\@endswallowall} \else\def\endcomment{\endsetcomment} \fi \newsavebox{\@rubishbin} \newenvironment{@swallow}{\setbox\@rubishbin\vbox\bgroup}{\egroup} \newenvironment{setcomment}{\list{}{\advance\leftmargin 5em \rightmargin\leftmargin}\item[] \em}{\endlist}
