Does anybody have a program that could, given a root file, trace all
\input and \include commands (actually, it should also be possible
to extend the list of commands which perform an \input) and list
the files that are used for that TeX run? (also nice would be the
same thing for MF)

Subject: Re: Problem with LaTeX optional argument
Keywords: LaTeX, error message
In a recent TeXhax, Michael Barr (at least that's the name in his example,
the message is unsigned and has a meaningless return address) asks whey the
following LaTeX input results in an error message:
\twocolumn[
\begin{center}
{\LARGE\bf Fuzzy Sets and Toposes}\\[3ex]
Michael Barr\\
Department of Mathematics and Statistics\\
McGill University\\
805 Sherbrooke St., W.\\
Montr\'eal, Qu\'ebec \\
Canada H3A 2K6
\end{center}
]
This is one of the "gotcha's" in LaTeX. The problem is that LaTeX - and a
human reading the input - thing of [ ... ] as a bracketed construct, so that
any embedded [ ... ] pairs are recursively matched. However, square brackets
have no special meaning to TeX. When TeX extracts the optional argument for
\twocolumn, it will match up to the first ], which will destroy the meaning
of the input.
The way to get around this is to enclose the argument in a { .. } pair. TeX
requires that macro arguments have matched curly braces. TeX will not look
inside them for a matching ] :
\twocolumn[{
\begin{center}

Subject: LaTeX question about indices
Keywords: LaTeX, indices
Is there a way to get an index with sub-entries automatically
created in LaTeX? As far as we know, \item and \subitem
(and \subsubitem) will create this (in the theindex environment)
if you already have the index entries with page numbers in a file.
But we would like to have the index automatically created by
\index, and we do not know if there is a way to do this.
By the way, what we are looking for is an index that looks like
topic, 100, 110, 200
subtopic, 100
subtopic2, 110
topic2, ...
If we can't find what we're looking for, we'll have to settle for
topic, 100, 110, 200
topic, subtopic, 100
topic, subtopic2, 110
topic2, ...
Please reply directly to me as I do not read this mailing list.
Thanks in advance for any help you can offer.

Subject: Re: Problems with Handy Little Font
Keywords: Handy Little Font
The problem you describe is most definitely a typo... it seems that
all of the braces {...} in the listings have been omitted.
Fortunately, there weren't very many.
They belong in the following places:
(1) when right or left appears on a draw statement (e.g.,
draw z18--z17right..z16--z7; should be
draw z18--z17{right}..z16--z7;
(2) at the point where you encountered the error, z6z5-z2 should be
z6{z5-z2}.

P.S. When you get it fixed, could you send me the source so I don't have to
type it in myself?

Does anybody have a TeX && METAFONT & ... change file(s) made explicitly for
MVS/TSO/E? I have been using the CMS version, and it compiles ok after
a little updating. However, the special routines ATTN202, USESTACK and
TERMATTN were not included. If these routines work for MVS/TSO/E then I
would be quite happy with them. (I am particularly interested in the USESTACK
routine since it is not too likely that we will actually be running
TeX from TSO/E, more likely as a batch job. This is because we are investigating
other TMPs, notably ROSCOE.) In any case, any help would be appreciated.

Subject: Problem with \global in LaTeX .AUX file
Keywords: LaTeX, \global
I have a question which I can find no easy answer to. I am writing a style
option file in LaTeX to evaluate the current page number, current running page
number and total number of pages to produce: Page x of y (x=runningpagenumber,
y=total number of pages). To do so is seemingly easy, simply define the
statements. The problem is that I need to write to the .AUX (\@mainaux) file a
token which points to a \global-ly defined variable. Without the \global
assignment, the .AUX does not supercede the default definition in the style;
without a default definition, the style file crashes. The relevant portions of
the .STY are below, as well as the .LIS from running the file. Any ideas,
solutions, etc., will be appreciated. Once this is cleaned up, the file will
go to Clarkson and be posted here. Thanks in advance.
FROM PAGEOF.STY (in development; prints Page x of y using a variation of
headerfooter.sty [where \oddpageheader, etc. are defined]).
The \enddocument definition uses:
\def\enddocument{\@checkend{document}
..... omitted text ......
\immediate\write\@auxout{% %%%%%%
\string\evaltext} %%%%%%%
..... omitted text ......
Where \evaltext points to
\def\evaltext{
\ifnum\totalpagecount > 0 \gdef\totalpagecounttext{\totalpagecount} \fi
\def\pageof{Page \therunningpage\ of \totalpagecounttext}
\ifnum\therunningpage = \thepage \oddpageheader{}{}{} \evenpageheader{}{}{} \fi
\ifnum\therunningpage < \thepage
>> \global\oddpageheader{}{}{\bf \thepage} \evenpageheader{\bf \thepage}{}{}\fi
\ifnum\therunningpage > \thepage
\oddpageheader{}{}{\bf \thepage} \evenpageheader{\bf \thepage}{}{} \fi
\pagefooter{}{\pageof}{}
}
The \global on the line marked >> in the \evaltext definition produces the
following from the .LIS file:
! Use of \global doesn't match its definition.
\evaltext ...ge < \thepage \global \oddpageheader
{}{}{\bf \thepage } \evenp...
although it writes \evaltext to the .AUX and understands that a \global
evaluation is needed to operate correctly (I am also aware that a \global is
ultimately needed on the following \ifnum conditional, as well, but why crash
twice?)

Subject: Paragraph with last line centred
Keywords: TeX, paragraphs
Try this:
\hsize=3in \vsize=5in
\parindent=0pt
\leftskip=0pt plus1fil
\rightskip=0pt plus-1fil
\parfillskip=0pt plus2fil
How can paragraphs be set with the last line centred, rather than
filled with blank space at the right? A simple solution is the four
assignments above (the assignment to {\tt\string\parindent} is
optional). This is much easier than collecting the paragraph in boxes
then dissecting the remains.
How does it work? On all but the last line of the paragraph, the
{\tt\string\leftskip} and {\tt\string\rightskip} cancel each other's
stretch component, so that the highest non-zero glue order for
stretching is the finite stretch of the spaces between words. These
expand so that the line fills the measure, and the infinite glue
doesn't stretch at all.
On the last line of the paragraph, the infinite glue doesn't cancel;
instead, there's 1fil at the left and a total of 1fil at the right.
The highest non-zero glue order is infinite, and the infinite glue
stretches to centre the line.

Subject: Equation numbers with \cases
Keywords: equation numbers, \cases
I would like to be able to format an equation with two parts as shown
below:
/
| x, x<<1; (1a)
f(x) = |
| 1/x, x>>1. (1b)
\
The bracket after the = sign is meant to be a large {. This is similar
to the output of the \cases command, except that I want equation numbers
on the right of each part. If I try
$$f(x)=\cases{x,&$x\ll0$;\eqno(1a)\cr 1/x,&$x\gg1$.\eqno(1b)\cr}$$
the equation numbers get stuck right after the equation, i.e., they are
not right justfied. Sticking \hfil or \hfill before the \eqno does not
help. I cannot find any examples like this in the Texbook. Does anyone
know an easy solution? Thanks.

I use two macros I've defined called \frlquote and \frrquote.
You can rename them anyway you want. Here they are:
\def\frlquote{\vbox{\offinterlineskip
\hbox{${\scriptscriptstyle\langle\!\langle}$}\kern-0.1pt}\hskip
-.6pt plus.3pt minus.2pt~}
\def\frrquote{~\hskip -.6pt plus.3pt minus.2pt\vbox{\offinterlineskip
\hbox{$\scriptscriptstyle\rangle\!\rangle$}\kern-0.1pt}}

Subject: Re: Needed: Help with hyphenation
Keywords: TeX, hyphenation
The reason that the word "photoproduction" doesn't hyphenate in the
example:
\hsize = .7in
\hyphenation{pho-to-pro-duc-tion}
photoproduction\par
\end
is that it's the first word of a paragraph. Technically (hidden under a
double dangerous bend on page 454 of The TeXbook), hyphenatable words
must be preceded by glue. The first word of a paragraph, instead, is
preceded by an empty box whose width is \parindent. You can make the
first word hyphenatable by putting a zero-width piece of glue before
it as follows:
\hsize = .7in
\hyphenation{pho-to-pro-duc-tion}
\hskip 0pt photoproduction\par
\end
In this version "photoproduction" hyphenates, but still causes an overfull
boxe because there is no stretchability in the glue on the first line.
Something like this will get rid of the error message:
\raggedright
\hsize = .7in
\hyphenation{pho-to-pro-duc-tion}
\hskip 0pt photoproduction\par

Subject: "Big" TeX for CMS
Keywords: Big TeX, CMS
Has anybody given any thought to creating a "big" TeX for CMS? Because
of VM's memory management, it seems that the standard method of
increasing array sizes etc. will not work since that will either
require ALL TeX users to get VM's with a larger storage area (not
necessarily a good thing), or require that a "big" and a "normal"
TeX co-exist, which could become somewhat of a pain to maintain.
The other alternative, allocating chunks of mem dynamically as they
are needed seems like a fairly substantial task and may cause
some performance degredation.
Comments anyone?

Subject: Re: Three questions (or something like that)
Keywords: macros
Somebody recentely asked for macros that are invoked on each line.
Here is one to generate a large, commented-out area--one of the
specific applications he asked about. Just something I happen to
have lying around.
The basic idea is that We read in the next line (delimited by the
end-of-line character in a group; after the group, we read in the
next line, and so on, until we hit the string \end{ignore} on a
line by itself, at which point we stop. And yes, this is some of
the most bizarre TeX code I've written; if you don't quite grok it,
don't feel too bad.
P.S.: Your 1st question fails because \begin{verbatim}, much like
this command, looks for the literal string \end{verbatim} to end
rather than actually *executing* the \end{verbatim} command when
it sees it. Thus, in cannot be nested.

Subject: Re: Graphics in Tex
Keywords: TeX, graphics
Tugboat 10.1 has finally mad it to the Antipodeas! I was interested to read the
two articles on graphics in TeX by David Rogers and Bart Childs et al.
I am stirred to make a few comments on them:
Firstly the two articles address different issues, both of which are
must be addressed in any graphics system for TeX.
David Roger's article address the problem of generating graphics from
within a TeX document. Bart Childs article discusses the inclusion of
graphics generated by other systems.
We have an ISO graphics standard (GKS).
Lets not invent yet another graphic file format.
CGM ( GKS's metafile ) is to graphic system what dvi files are to Tex
and there already is a lot of software around for translating them to
various device dependent forms.
I agree with David that CGM is more powerful than is necessary for this
aplication but think that the fact that there is alot of GKS system in use
now is too important to ignore. I like Davids subset of graphics operators,
but I think that they should emit specials into the dvi file with CGM commands.
The dvi program can then assemble the CGM file from the embeded specials and
pass it to the CGI processor to convert it into device dependent form.
If the dvi driver does not have the ability to handle CGM files then it will
ignore the specials.
This scheme involves modifying current dvi drivers but not the definition of
the dvi files. I know that this will take time but the alternative are systems
that involve lots of steps ( Bart Childs lists 6 steps to include a cgm file)
and most of our users will find it easier to do the whole job on a Mac and
not bother with TeX at all.
One of the stickest problems is letting TeX know what sized box to
allocate for included graphics. Don Berrymans program is a step in
the right direction. Its a pity that CGM files don't have a direct
equivalent of PostScript's %%Bounding box.
What ever scheme is adopted it must be simple, easy to use, address
inclusion of graphics generated by other software and support the
generation of graphics from within TeX its self.

Subject: PostScript definitions in TeX
Keywords: PostScript, TeX
To facilitate the inclusion of PostScript definitions in your TeX
document, most dvi2ps drivers out there support some variant of the
`\special{header=fn}' which includes a prologue file that may
contain definitions.
Note that PostScript definitions in the `Page' portion of the PostScript
document will not span that page due to save/restore pairs.
Drivers such as my dvips that support `literal' PostScript specials
(i.e., `\special{"any PostScript text here}') should also support
literal PostScript definitions (in dvips, `\special{! PS definitions}')
that are collected and inserted with the other header information.
