README for DTL package - Thu 9 March 1995
|
||||
-----------------------------------------
|
||||
Author: Geoffrey Tobin <G.Tobin@ee.latrobe.edu.au>
|
||||
Version: 0.6.1
|
||||
CTAN Archive-path: dviware/dtl
|
||||
Brief Description:
|
||||
DTL (DVI Text Language) files are equivalent to TeX's DVI files,
|
||||
but are humanly readable, instead of binary. Two programs are
|
||||
provided to translate between DVI and DTL: dv2dt, dt2dv.
|
||||
dt2dv warns if byte addresses or string lengths recorded in a DTL
|
||||
file are incorrect, then overrides them. This makes DTL files
|
||||
editable. It also allows quoted apostrophes (\') and quoted quotes
|
||||
(\\) in strings. The current DTL variety, sequences-6, separates
|
||||
font paths into directory and font, which makes them freely editable.
|
||||
In this release, DTL line numbers are correctly calculated, and three
|
||||
memory leaks have been fixed.
|
||||
Keywords: dvi, TeX
|
||||
Includes:
|
||||
Makefile README dt2dv.c dtl.h dv2dt.c
|
||||
man2ps dtl.doc dvi.doc dt2dv.man dv2dt.man
|
||||
hello.tex example.tex tripvdu.tex edited.txt
|
||||
|
||||
Motivation:
|
||||
|
||||
When TeX has typeset a document, it writes its handiwork to a DVI
|
||||
file, for DVI processing software (such as viewers, printer drivers,
|
||||
dvidvi, and dvicopy) to read.
|
||||
|
||||
The file dvi.doc lists the DVI file commands, with their opcodes
|
||||
(byte values), nominal command names, arguments, and meanings. For a
|
||||
detailed description of DVI file structure, see one of these:
|
||||
1. Donald E. Knuth's book _TeX: The Program_;
|
||||
2. The file tex.web, which contains source and documentation for TeX:
|
||||
CTAN: systems/knuth/tex/tex.web
|
||||
3. The source for Knuth's dvitype program:
|
||||
CTAN: systems/knuth/texware/dvitype.web
|
||||
4. Joachim Schrod's DVI drivers standard document, the relevant part
|
||||
of which is at
|
||||
CTAN: dviware/driv-standard/level-0
|
||||
|
||||
Sometimes human beings are interested to see exactly what TeX has
|
||||
produced, for example when viewing or printing of the DVI file gives
|
||||
unexpected results. However, a DVI file is a compact binary
|
||||
representation, so we need software to display its contents.
|
||||
|
||||
Binary file editors, when available, can show the DVI bytes, but not
|
||||
their meanings, except for the portions that represent embedded text.
|
||||
In particular, the command names are not shown, and the command
|
||||
boundaries are not respected.
|
||||
|
||||
By contrast, Knuth's dvitype program is designed as an example of a
|
||||
DVI driver. However, dvitype is inconvenient for studying the DVI
|
||||
file alone, for the following reasons:
|
||||
1. Being a DVI driver, dvitype endeavors to read the TFM font metric
|
||||
files referenced in the DVI file. If a TFM file is absent, dvitype
|
||||
quits with an error message.
|
||||
2. When it starts, it prompts the user interactively for each of a
|
||||
series of options.
|
||||
3. Even the least verbose option gives masses of information that is
|
||||
not contained in the DVI file, coming instead from a combination of
|
||||
the data in the DVI file and TFM files.
|
||||
4. It does NOT show the DVI information in a way that accurately
|
||||
reflects the structure of the DVI file.
|
||||
5. Its output, if redirected to a file, produces a very large file.
|
||||
6. There is no automated procedure for converting the output of
|
||||
dvitype back to a DVI file, and doing it by hand is totally
|
||||
unreasonable.
|
||||
|
||||
The first disadvantage is a killer if a TFM file is absent.
|
||||
Disadvantages two to four make dvitype very inconvenient for studying
|
||||
a DVI file. The fifth problem makes dvitype's output tedious,
|
||||
disk-hungry (so one deletes it almost immediately), and unsuitable for
|
||||
file transfer.
|
||||
|
||||
The sixth disadvantage of dvitype is important to those people who are
|
||||
interested in editing DVI files. Since the DVI files refer explicitly
|
||||
to their own internal byte addresses, it's very easy to mess up a DVI
|
||||
file if one were to try to edit it directly, even apart from the problem
|
||||
of how to recognise a command.
|
||||
|
||||
So an exact, concise, textual representation of a DVI file is needed,
|
||||
but dvitype does not produce one.
|
||||
|
||||
Resolution:
|
||||
|
||||
Therefore, working from Joachim Schrod's description, I designed DTL
|
||||
and its conversion programs dv2dt (DVI -> DTL) and dt2dv (DTL -> DVI),
|
||||
which are provided as C sources:
|
||||
|
||||
dtl.h
|
||||
dv2dt.c
|
||||
dt2dv.c
|
||||
|
||||
Although I was motivated by the TFM <-> PL conversion provided by
|
||||
Knuth's tftopl and pltotf programs, I deliberately designed DTL to be
|
||||
a much more concise and literal translation than the `property list'
|
||||
structure exemplified by PL. The result is that a DTL file is
|
||||
typically three times the size of its equivalent DVI file. The
|
||||
document dtl.doc lists the correspondence between the DTL command
|
||||
names and the (nominal) DVI command names.
|
||||
|
||||
A clear advantage of an exact two-way conversion is that we can check
|
||||
(and prove) whether the converters worked truly on a given DVI file.
|
||||
The provided plain TeX files:
|
||||
example.tex
|
||||
tripvdu.tex
|
||||
can be used to test whether the compiled programs are behaving
|
||||
sensibly. Whereas example.tex is a simple document that uses a
|
||||
variety of plain TeX commands, tripvdu.tex provides a kind of
|
||||
`trip test' for DVI processor programs. Both documents are taken,
|
||||
with permission, from Andrew K. Trevorrow's dvitovdu (alias dvi2vdu)
|
||||
distribution (and are also part of the dvgt viewer distribution).
|
||||
|
||||
The Makefile might have to be edited for your site, as it assumes
|
||||
gcc for your C compiler. Makefile compiles dv2dt and dt2dv, then
|
||||
runs tex on example.tex and tripvdu.tex, and also converts the
|
||||
resulting DVI files to DTL files, back to DVI files (with a change
|
||||
of name), then back again to DTL files, so that the results can be
|
||||
compared using a textual differencing program. (Many computer systems
|
||||
have such a program; on unix, as assumed by Makefile, this is named
|
||||
`diff'; ms-dos has one named `comp'.) This should produce a
|
||||
zero-length .dif file for each document, proving that the two DTL
|
||||
files are identical.
|
||||
|
||||
A keen tester might also use a binary difference program on the DVI
|
||||
files, to check that they are identical, as they need to be. (On unix
|
||||
systems, the `diff' program suffices for that purpose.)
|
||||
|
||||
Note:
|
||||
|
||||
In representing numeric quantities, I have mainly opted to use
|
||||
decimal notation, as this is how most of us are trained to think.
|
||||
However, for the checksums in the `fd' (font definition) commands, I
|
||||
chose octal notation, as this is used for checksums in Knuth's PL
|
||||
files, against which DVI files must be compared when a DVI driver
|
||||
loads a font.
|
||||
|
||||
Caveat:
|
||||
|
||||
The length of DTL commands is limited by the size of the line buffer
|
||||
in dt2dv.c.

|
||||
driver program. In DTL files, font directory names
|
||||
and font names are preceded by a length field,
|

.BR dvitype (1)
|

cannot be used in batch mode, and its output is
|
||||
not well-suited for conversion back to a DVI file.

.SH DESCRIPTION
|
||||
.B dv2dt
|
||||
converts a binary \*(Te\& DVI file to an editable
|
||||
text file in DTL
|
||||
.RI ( "DVI Text Language" )
|
||||
format. The companion
|
||||
.BR dt2dv (1)
|

utility can convert the DTL file back to a binary
|
||||
DVI file.

.\"======================================================================
|
||||
.SH "DVI COMMAND DESCRIPTION"
|
||||
\*(Te\& DVI files contain a compact binary
|
||||
description of typeset pages, as a stream of
|
||||
operation code bytes, each immediately followed by
|
||||
zero or more parameter bytes. The format of DVI
|
||||
files is fully described in Donald E. Knuth,
|
||||
.IR "\*(Te\&: The Program" ,
|
||||
Addison-Wesley (1986), ISBN 0-201-13437-3, as well
|
||||
as in the
|
||||
.BR dvitype (1)
|
||||
literate program source code.
|
||||
.PP
|
||||
For convenience, we provide a summary of DVI
|
||||
commands here. In the following list, operation
|
||||
code bytes are given as unsigned decimal values,
|
||||
followed by their symbolic names (not present in
|
||||
the DVI file), and a short description. A
|
||||
designation like
|
||||
.I b[+n]
|
||||
means that the operation code byte is followed by
|
||||
a parameter
|
||||
.I b
|
||||
which uses
|
||||
.I n
|
||||
bytes, and is signed. Without the plus sign, the
|
||||
parameter is unsigned. Signed integer parameter
|
||||
values are always represented in two's complement
|
||||
arithmetic, which is the system followed by most
|
||||
computers manufactured today, including all
|
||||
personal computers and workstations.

\subhead{What is \TeX?}
|
||||
|
||||
\TeX\ (pronounced ``teck'') is a computerized typesetting system developed by
|
||||
Donald Knuth and others at Stanford University. It is used to create
|
||||
high-quality documents, particularly those containing mathematics.
|
||||
The name \TeX\ is an uppercase form of the Greek letters $\tau\epsilon\chi$,
|
||||
the first three letters of a Greek word meaning {\sl art} as well as
|
||||
{\sl technology}.
|
||||
The lowering of the ``E'' is a reminder that \TeX\ is about typesetting,
|
||||
which can be thought of as the next stage beyond word processing.
|
||||
On devices where such lowering is difficult or impossible you may see \TeX\
|
||||
written as {\tt TeX}.
|
||||
|
||||
% the above blank line ends the first paragraph
|
||||
|
||||
Most word processors allow you to
|
||||
create and modify a document interactively --- what
|
||||
you see on the screen is usually what your output will look like.
|
||||
\TeX\ does {\it not} work in this way.
|
||||
Like other typesetting systems (such as SCRIBE and
|
||||
{\sl troff\/}), \TeX\ is known as a ``document compiler''. Using your
|
||||
favourite text editor you need to create a file containing the
|
||||
text of your manuscript along with the \TeX\ typesetting commands.
|
||||
\TeX\ gives you the ability to produce printed matter with a quality
|
||||
matching that found in books, depending on the output device.

with a resolution of 240 dots per inch.
|
||||
This publication shows both the capabilities of \TeX\ and
|
||||
the output quality of the laser printer.
|
||||
|
||||
\subhead{Fonts}
|
||||
|
||||
One of the more obvious advantages of \TeX\ is the large range of fonts from
|
||||
which you can choose. A font is a collection of characters each having a
|
||||
similar size and style. Some of the fonts currently available include:
|
||||
$$ % enter display math mode just to get space above and below \line
|
||||
\line
|
||||
{\hfil % infinitely stretchable glue
|
||||
\rm roman\hfil \sl slanted\hfil \it italic\hfil \bf boldface\hfil
|
||||
\tt typewriter\hfil \ss sans serif\hfil \sm small caps\hfil
|
||||
} % take care to ensure each { has a matching }
|
||||
$$
|
||||
Many of these also come in a variety of sizes:
|
||||
$$
|
||||
\centerline{{\bigrm from the very big},~ % extra space after comma
|
||||
{\ninerm to the very small},~
|
||||
{\fiverm to the ridiculous}.}
|
||||
$$
|
||||
Apart from a large selection of mathematical symbols,
|
||||
many special characters and accents are available:
|
||||
$$
|
||||
\vbox
|
||||
{\tabskip 10pt plus 1fil % glue before and after all columns
|
||||
\halign to\hsize
|
||||
{& \hfil#\hfil\cr % specify a variable number of centred columns
|
||||
\copyright& \it\$& \S& \P& \dag& \ddag&
|
||||
$\circ$& $\bigcirc$& % some symbols must be accessed from math mode
|
||||
$\leftarrow$& $\rightarrow$& $\triangle$& $\clubsuit$&
|
||||
\`a& \'e& \c c& \^o& \"u\cr
|
||||
}
|
||||
}
|
||||
$$
|
||||
\TeX\ does a few subtle things automatically.
|
||||
Certain sequences of characters in your text will
|
||||
be replaced by {\sl ligatures} in the printed output (consider the ``{\tt ffi}''
|
||||
in ``difficult''), while other pairs of characters need to be {\sl kerned}
|
||||
(e.g., the ``o'' and ``x'' in ``box'' look better if they are moved closer
|
||||
together). The range and quality of fonts available will continue to improve.
|
||||
|
||||
\subhead{Mathematics}
|
||||
|
||||
A major design goal of \TeX\ was to simplify the task of typesetting
|
||||
mathematics --- and to do it properly. Mathematicians will be pleasantly
|
||||
surprised at the ease with which formulae and expressions can be created;
|
||||
from simple in-line equations
|
||||
such as $e^{i\pi}=-1$ and $f_{n+2}=f_{n+1}+f_n$, to more extravagant displays:
|
||||
$$
|
||||
\sum_{k\ge1} \sqrt{x_k-\ln k}\quad\ne\quad
|
||||
\int_{0}^\infty {e^{-x^3}+\sqrt{x} \over \left(123-x\right)^3} \,dx
|
||||
$$
|
||||
\TeX\ looks after most of the nitty gritty details, such as spacing things
|
||||
correctly and choosing the right sizes for superscripts, parentheses,
|
||||
square root signs etc. (The discoverer of the above relation wishes to
|
||||
remain anonymous.)
|
||||
|
||||
\subhead{Alignment}
|
||||
|
||||
The preparation of tabular material such as in lists and matrices can be a
|
||||
tedious job for a person armed only with a typewriter and a bottle of
|
||||
correction fluid. With a little help from \TeX, computers can make it so
|
||||
much easier:
|
||||
$$
|
||||
\vcenter % a vertically centred \vbox
|
||||
{\tabskip 0pt % no space before column 1
|
||||
\halign to 3.5in % width of table
|
||||
{\strut#& % col 1 is a strut
|
||||
\vrule#\tabskip .5em plus2em& % col 2 is a vrule; also set col spacing
|
||||
#\hfil& % col 3 is left justified
|

|

|
||||

|

\subhead{Other features}
|
||||
|
||||
Space does not permit examples of all the things \TeX\ can do. Here are some
|
||||
more features you might like to know about:
|
||||
|
||||
\item{$\bullet$}
|
||||
Multi-column output can be generated.
|
||||
|
||||
{\parskip=0pt % temporarily turn off the skipping between paragraphs
|
||||
\item{$\bullet$}
|
||||
\TeX\ has a very sophisticated paragraph building algorithm and rarely needs
|
||||
to resort to hyphenation. Paragraphs can be indented and shaped in many
|
||||
different ways.
|
||||
|
||||
\item{$\bullet$}
|
||||
Automatic insertion of footnotes,\footnote{\dag}{\ninerm Here is
|
||||
a footnote.} running heads, page numbers etc.
|
||||
|
||||
\item{$\bullet$}
|
||||
\TeX\ makes provision for generating a table of contents, a bibliography, even
|
||||
an index. Automatic section numbering and cross referencing are also possible.
|
||||
|
||||
\item{$\bullet$}
|
||||
A powerful macro facility is built into \TeX. This lets you do some very
|
||||
useful things, like creating an abbreviation for a commonly used phrase, or
|
||||
defining a new command that will have varying effects depending on the
|
||||
parameters it is given. A macro package can enhance \TeX\ by making it much
|
||||
easier to generate a document in a predefined format.
|
||||
\par % end the last paragraph BEFORE ending the group
|
||||
} % \parskip will now revert to its previous value
|
||||
|
||||
\subhead{What CAN'T \TeX\ do?}
|
||||
|
||||
Complex graphics such as diagrams and illustrations pose
|
||||
a major problem --- at the moment you have to leave an appropriate amount of
|
||||
blank space and paste them in later.
|
||||
Graphic facilities are the subject of current research.
|
||||
|
||||
\subhead{\TeX\ and VAX/VMS}
|
||||
|
||||
The \TeX\ source file used to generate this document is available for
|
||||
inspection on any VAX node that has \TeX ---
|
||||
just type `{\tt scroll tex\char'137 inputs:example.tex}'.
|
||||
A few steps are needed to print such a file:
|
||||
|
||||
\item{(1)}
|
||||
Type `{\tt tex example}' to ``compile'' the file.
|
||||
(\TeX\ looks for a {\tt .tex} file by default. If it can't find the given
|
||||
file in your current directory it will look in {\tt tex\char'137 inputs}.)
|
||||
Two new files will be created in your current directory:
|
||||
{\tt example.dvi} and {\tt example.lis}.
|
||||
The former is a device independent description of the document;
|
||||
the latter is simply a log of the \TeX\ run.
|
||||
|
||||
{\parskip=0pt % temporarily turn off \parskip
|
||||
\item{(2)}
|
||||
Type `{\tt dvitovdu example}' to preview the document on a terminal screen.
|
||||
This program can be used to detect a variety of formatting problems,
|
||||
saving both time and paper.
|
||||
|
||||
\item{(3)}
|
||||
Type `{\tt imprint example}' to print the document.
|
||||
(Note that the DVIto\kern-.15em VDU and IMPRINT commands
|
||||
accept a {\tt .dvi} file by default).
|
||||
|
||||
} % restore \parskip
|
||||
|
||||
Detailed help on all these commands is available on-line --- try typing
|
||||
`{\tt help tex}' to get started.

% This page has a paragraph illustrating most of the characters from the

% standard roman TeX text font.

\message{Standard paragraph.}
|

\rm
|
||||
Our task is to create a paragraph illustrating what a typical piece of text
|
||||
looks like in the standard \TeX\ font. It should be stressed that not all
|
||||
\TeX\ fonts can be used for typesetting text. We need to show most of the
|
||||
characters in this font---for instance, something like ``the quick brown fox
|
||||
jumps over a lazy dog'' would use all the lower-case letters. Hmmm \dots\
|
||||
how about ``THE QUICK BROWN FOX JUMPS OVER 9876543210 LAZY DOGS'' to make
|
||||
sure we show all the upper-case letters and digits? Such a paragraph would
|
||||
hardly be typical! Then there's ligatures (try and fit in words like
|
||||
fluffy, waffle, firefly, difficult) and examples of kerning (boxer, cooked,
|
||||
vowel). Not to mention the various accents and other special letters:
|
||||
prot\'eg\'e, r\^ole, na\"\i ve, \AE sop's \OE vres en fran\c cais.
|
||||
But how do we put all this stuff into a paragraph that makes sense!?
