Subject: getting TOC _before_ first PART in modified book style
Date: 3 Sep 92 15:20:27 GMT
Organization: Keele University, England

We have a style here kthesis.sty which is based on book.sty - it is for 
producing theses which meet the requirements of Keele University.

It puts in a table of contents (and LOT and LOF if necessary) immediately
_before_ the first chapter - which is where you want it. However if you
use the \part command to organise your chapters the TOC goes _after_ the
PART I and before CHAPTER 1.

I guess the kthesis.sty is saying "when the chapters start flush out the
TOC, LOT and LOF" when it should say "when the chapters OR parts start etc".
I think the bit of the kthesis.sty file that controls this is:-

  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  %                         TABLE OF CONTENTS                            %
  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   
  \def\l@chapter#1#2{\smallskip\@dottedtocline{2}{0em}{2em}{{\bf #1}}{\bf #2}}%
   
  \setcounter{tocdepth}{4}
   
  \def\make@tableofcontents{\@tableofcontents}
   
  \def\@tableofcontents{%
      {\baselineskip=\origbaselineskip\parindent=0pt
      \tableofcontents
      \listoffigures
      \listoftables}
      \newpage
      \c@page=1
      \global\def\thepage{\arabic{page}}}
  % The following macros avoid printing a heading if there are no
  % following lines (e.g., no tables, or no figures).

Any idea what I need to alter to make it deal with \part correctly?

remember seeing something a while ago about a program or shell script

Hello. I have successfully created my plain and lplain fmt files for EmTeX

files are used for. Are they configuration files? If so, what information 
inside of it is necessary and what is it used for?

(and does the fmt.bat file create fmt files the same way as creating the

X-Gateway-Source-Info: Mailing List

I have a manual for a fault tree program that we sell (called FaultrEASE).
The manual is in TeX, using the TeXtures implementation from Blue Sky.
So far, so good. However, the program also has on-line help, which is
basically a de-TeXed version of the manual. I produce this using a LISP
program which I have taught to recognize TeX macros and do simple-minded
transforms in their place. I tried using GNU's deTeX, but this does *no*
formatting at all, so the output is not very readable. Is there any code
(TeX, LISP, or otherwise) for transforming TeX documents into flat (but
somewhat readable) ASCII, suitable for an on-line manual?

Following are some of the LISP functions I use, to give you an idea of what
I'm trying to do:

(defun expand-section (stream)
  "Capitalizes the section name,
   places two blank lines before it, and one after."
  (let ((section (read stream)))
    (format nil "~2%~a~%" (string-upcase section))
    ))

(defun deTeX (input output)
  "Remove TeX commands from an input stream, ~
   sending results to an output stream."
  (let ((*readtable* *TeX-readtable*))
    (loop
      (let* ((char (read-char input nil :eof))
             (string
              (case char
                ((#\{ #\} #\$ ))
                (#\% (read-line input) (peek-char t input nil) nil)
                (#\\ (expand-def input))
                (:eof (return t))
                (t char)
                )))

Thanks for the help everyone. The general consensus seems to be to use:

	$^\circ$C

or to save typing 

	\newcommand{\degc}{\mbox{$^\circ$C}}

My original attempt at using \symbol{"17"} was flawed since character "17
is an "accent" symbol (a circle to be place above "A" etc) and not the
degree symbol like I hoped. I assume that is why I had the spacing
problem.

A related question to those of you who are familiar with troff and TeX or

Hi all,

    Lately I have been trying to bring up bibtex by Oren Patashnik
on a DECstation 3100 (Ultrix 2.x, gcc 1.39). I had to start
from making a web2c and finally got a bibtex program which hangs after
printing 

The top-level auxiliary file: citex.aux
The style file: plain.bst

it should print 

Database file #1: knuth.bib

and quit (because I have access to a bibtex on an IBM RS/6000).
What I had to do is to change bibtex.c, so that the
while(true) loop in the main_body() function becomes while(i<10){...;i++}.
After this termination, the .bbl file seems to be OK.

   * Is there some package for the DECstation 3100 (Ultrix 2.x)
     which does not need all these processing involving
     web2c, sed, whatever. Why did not the author simply
     give us a clean C program? I had to pull off web2c from
     one place, and bibtex.tar.Z from another. 
     
   * is there anything fundamentally wrong with the above
     kludge (I mean I do know that bibtex.c is not supposed
     to be changed; but I do not know Pascal --- I am not
     a computer science graduate, despite my mail address).

   * BTW, what is the latest version of bibtex?

Thank you for any pointers

The window.sty looks quite nice (I've only just looked at the output
from the example file so far), but before this style lands on an
archive somewhere, please remove the first and last lines.

\makeatletter

This is not so bad, but is not needed.

\makeatother            % disable use of @ as a letter

This is a BUG, as it also disables almost all style options that
appear after window in the \documentstyle command.

David

It is well worth doing a grep (UNIX for search) on your main LaTeX
style directory for \makeatletter. Lots of style files available have
this bug.

\makeatletter or \catcode`\@=11 are not always wrong, but they should
never still be in force at the end of the .sty file.

Well, yes, Rainer, but you omit to mention that there was no definition

I am trying to use SliTex To prepare a set of slides for a presentation.
The materials are largely drawn from the paper written in LaTeX. I need

no longer use the citations and figures in the same way as I did in LaTeX.
For figures, I can print them separately, but as far as ciatation is concerned,
I cannot figure out a better way other than manually put stuffs like [ABC 92]

Is there a better SliTeX {sty, or, tex} that can handle figure and
bibliography stuffs?

  You don't need to do this! Try this:
  \font\bgreek=cmmib10 % bold symbols at 10 pt (see p430 of TeXbook for font)
  \def\balpha{\hbox{\bgreek\char`013}} % gives a bold alpha, etc.
  Now you can say $$x = \balpha$$.

yes, in fact i use PMB only for the script and scriptscript sizes. (I

Well, \verb works by removing all special meaning to all characters,
then reading its argument. If you define a macro like the above,
the characters already have a fixed meaning, and \verb can only change
the meaning of characters not already read in.
So the trick would be to try to let \verb see a closing brace instead
of the opening one.

[I'm reposting this because we've found three volunteers and would

the people originally earmarked couldn't manage) G]


Hello,
we're looking for volunteers to try out the 'Type & Set' system which
was written up in the April edition of TugBoat.  If you read the
article, and are interested, let us know please.

We're only looking for three or four people, and those who volunteer
will be expected to use the system seriously for about a month, and
write a report at the end outlining any problems you found.

The only bribery we can offer is that you'll get a free copy of the
final version and the same level of support as paying customers.

This system is especially good for journal production, or anywhere
that large volumes of documents go out regularly all in the same style.
It's TeX-based, but tries to present a simpler interface, and can be
used by non-techies with a minimum of training.  We'd expect field
trial sites to have at least one competant techie though, even if
most of your dataprep people aren't.

Volunteers are welcome from *anywhere* in the world - US or UK or otherwise.
It'll be a good test of our customer support...

Thanks if you're willing to help.

I have found the 286 version of emTeX to be quite satisfactory. I run it

Subject: dvips bug?
Summary: including postscript into LaTeX
Keywords: postscript

I have a postscript file which prints fine on our postscript
printer.  I am trying to include this file into a LaTeX
document as a figure.  I run dvips and try to print the new
postscript file.
The printer aborts printing the new file.

(A little debugging has pinpointed the source of the ``error''
 on an apparent encoding of text that appears in the file as
 a large block of numbers and letters...possibly hexadecimal
 run together.  When I comment the block out, the lines of the
 figure are printed ok -- no text)

So I am concluding that there is some negative interaction
with dvips and my file.  Is it possible that the postscript
file is a different `version' than what dvips assumes?

Thanks for any comments,
