# 1. What is Yap?

You use Yap(1) to view a DVI file compiled by TeX. Yap tries hard to follow the WYSIWYG-principle: what you see (on screen) is what you get (when you take the paper out of the tray).

This document will explain

You can conclude from the version number 0.97, that Yap is still under development. You can get the newest development version from the MiKTeX Project Page at http://www.miktex.de.

# 2. How to open a DVI file

You can open a DVI file

• by double-clicking its icon in a Windows Explorer window
• by invoking Yap from the command line (see section 10. Command line switches).
• via Drag&Drop
• with the command File|Open'
• by selecting an MRU(2) entry from the File menu

# 3. Printing DVI Documents

There are two different methods to send a DVI document to the printer:

1. By means of the standard print command (File|Print...').
2. By means of Dvips (File|Print PostScript...').
If your DVI document contains PostScript specials (e.g. EPS inclusions), than you can't use the standard print command.

The Dvips interface also works in conjunction with non-PostScript printers, provided that you have GhostScript installed on your workstation.

### 3.2.1 Print PostScript Dialog Box

This dialog box allows you select various Dvips options.

GhostScript device

Check this button if you want to pipe the Dvips output through the GhostScript interpreter (gswin32c.exe). GhostScript will be invoked with the following options:

-sDEVICE=device
Output goese to the specified device.

-dBATCH
Causes GhostScript to quit when the document has been printed.

-dNOPAUSE
Disables the prompt and the pause at the end of each page.

-dSAFER
Disables unsafe operators.

PS File

Check this button if you want to send the Dvips output to a PostScript printer or if you want to save the output in a PostScript file. Enter a port name (such as lpt1' or \\servername\printer') or a file name.

Print range

Select the pages that you want to print.

Extra Dvips options

You can enter additional Dvips options here.

Reconfirm command line

Check this button if you want to inspect the Dvips command line.

# 4. Forward and Inverse Search

Yap is capable of searching the DVI file for so called source specials. This feature can help you to optimize the edit-compile-view cycle:

• While editing a TeX source, issue an appropriate command that invokes Yap to display the TeXed document. Yap will indicate it's idea of the current edit position by drawing a small circle. This is called forward search.
• While viewing the TeXed document with Yap, move the mouse cursor over a paragraph that you want to edit next. Double-click to jump to the editor. Yap will try to move the text cursor to the correct source line. This is called inverse search.
 Inserting Source Specials How to enrich your document with source specials Forward Search How to search forward Inverse Search Initiating Inverse Search

 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

## 4.1 How to enrich your document with source specials

TeX inserts source specials into the DVI file, if you specify the command-line switch --src-specials'. You simply can say

tex --src-specials mybook.tex

and the TeX compiler will insert one source special at the beginning of each paragraph.

You can control the frequency of embedded source specials by specifying where to insert the specials into the DVI file:

tex --src-specials=where mybook.tex

The where argument must be a comma-separated value list. Legal values are:

cr
Causes TeX to insert one source special at the end of each table row.

display
Causes TeX to insert one source special at the beginning of each display.

hbox
Causes TeX to insert one source special at the beginning of each hbox.

math
Causes TeX to insert one source special upon entry to math mode.

par
Causes TeX to insert one source special at the beginning of each paragraph.

vbox
Causes TeX to insert one source special at the beginning of each vbox.

## 4.2 How to search forward

Forward search is initiated by specifying --find-src-special on the Yap command-line (see section 10. Command line switches).

But initiating forward search from the command-line is rather invonvenient. It makes more sense to initiate forward search out of the text editor. The editor must be capable of starting Yap with a correct --find-src-special directive. Two popular text editors which are capable to initiate forward search are GNU Emacs and WinEdt.

 Emacs Configuring Emacs for forward search.

 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

### 4.2.1 Configuring Emacs

You will need the Emacs package Auc-TeX, which provides an enhanced TeX environment.

The following code should be added to your .emacs':

(setq TeX-command-list
'(("TeX" "tex --src \"\\nonstopmode\\input %t\""
TeX-run-TeX nil t)
("LaTeX" "%l --src \"\\nonstopmode\\input{%t}\""
TeX-run-LaTeX nil t)
("View" "yap -1 -s \"%n %t\" %d"
("BibTeX" "bibtex %s" TeX-run-BibTeX nil nil)
("Index" "makeindex %s" TeX-run-command nil t)))

TeX' (resp. LaTeX') creates a DVI file which contains source file information.

View' starts Yap (if it is not already running) and moves the focus to the corresponding DVI location.

 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

## 4.3 Initiating Inverse Search

Provided that the DVI document contains source file information (see section 4.1 How to enrich your document with source specials), you can initiate inverse search by double-clicking inside the Yap document window.

# 5. Graphics Inclusions

Yap supports the following graphics formats:

EMF
Enhanced Metafiles (*.emf).

WMF
Windows Metafiles (*.wmf).

BMP
Device-independant Bitmap (*.bmp).

EPS
Encapsulated PostScript (*.eps); requires GhostScript.

GIF, PNG, TIFF, ...
All graphics formats that are supported by the netpbm graphics suite.

 WMF Windows Metafiles BMP Windows Bitmap (BMP) Files EPS Encapsulated PostScript Other Formats Other Graphics Formats

 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

## 5.1 Windows Metafiles

Yap has built-in support for Windows Metafiles (WMF) and Enhanced Metafiles (EMF).

Example

You can use the graphicx' package to include WMF/EMF files. For example, the following LaTeX code will include the WMF file drawing.wmf:

\usepackage{graphicx}
\DeclareGraphicsRule{.wmf}{bmp}{}{}% declare WMF filename extension
\begin{document}
\includegraphics[width=2in,height=1in]{drawing.wmf}
\end{document}


 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

## 5.2 Windows Bitmap (BMP) Files

Yap has built-in support for Windows Bitmap Files.

Example

You can use the graphicx' package to include BMP files. For example, the following LaTeX code will include the BMP file picture.bmp:

\usepackage{graphicx}
\begin{document}
\includegraphics[width=2in,height=1in]{picture.bmp}
\end{document}


 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

## 5.3 Encapsulated PostScript

Yap displays EPS figures with the help of GhostScript, which must be installed on your computer.

Example

You can use the graphicx' package to include EPS files. For example, the following LaTeX code will include the EPS file drawing.eps:

\usepackage{graphicx}
\begin{document}
\includegraphics{drawing.eps}
\end{document}


 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

## 5.4 Other Graphics Formats

Yap can convert almost any graphics file into an equivalent Windows Bitmap (BMP) file, provided that a suitable filter program is available. The BMP file will then be displayed instead of the original file.

Many filters are included in the netpbm graphics suite, which can be downloaded from the CTAN directory systems/win32/miktex/util.

Example

You can use the graphicx' package to include graphics files. For example, the following LaTeX code will include the GIF file picture.gif:

\usepackage{graphicx}
\DeclareGraphicsRule{.gif}{bmp}{}{}% declare GIF filename extension
\begin{document}
\includegraphics[width=2in,height=1in]{picture.gif}
\end{document}

 Filters Specifying filters

 [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ]

### 5.4.1 Specifying filters

New filters have to be specified in the [Graphics] section of the MiKTeX configuration file (miktex.ini'). A filter specification has the syntax .xxx.bmp=command', where

• .xxx' is the original filename extension
• command' is the command line, which converts an XXX file into a BMP file.
The command line must contain the following place-holders

%i'
The name of the input file which has to be converted.

%o'
The name of the output (BMP) file.

Example

The following specification defines a GIF filter:

[Graphics]
.gif.bmp=giftopnm %i | ppmtobmp -windows > %o

This filter works as follows:

1. giftopnm is used to convert the .gif file into a portable bitmap, which is written to a pipe (|')
2. ppmtobmp is used to convert the portable bitmap, which is read from the pipe, into the final BMP file.

# 10. Command line switches

The general Yap command line syntax is

yap [options] [dvifile]

The following options are recognized:

--find-src-special srcspecial
-s srcspecial
Initiate a forward search (see section 4. Forward and Inverse Search). The syntax for srcspecial is NNFILENAME' (i.e. line number followed by source file name). See the example below.

--goto-hyper-label label
Jump to a HyperTeX label. The label must have been inserted as an html: special.

--single-instance
-1
Use an already opened Yap application window (if one exists). This flag prevents multiple Yap applications instances.

--unregister
Remove Yap related settings from the Windows Registry

Example

You want Yap to do a forward search to the DVI location corresponding to line 41 of the source file mydoc.tex. The name of the DVI file is mydoc.dvi. The forward search is initiated like this:

yap -s 41mydoc.tex mydoc.dvi

If you already have an open Yap application instance, and you don't want to start another instance, then add the -1 flag:

yap -1 -s 41mydoc.tex mydoc.dvi
