NAME
pdfopen, pdfclose - open or close a PDF file viewer
SYNOPSIS
pdfopen [ options ] [ --file ] file.pdf
pdfclose [ --file ] file.pdf
OPTIONS
-h, --help, -?
output help and exit.
-v, --version, -V
output the version number and exit.
-p <n>, --page <n>
when starting the viewer, display page <n> of the document (notes: not all viewers support this
feature, and even in those cases this option only has effect when the document is initially
loaded). This option is over-ridden by -g.
-g <named destination>, --goto <named destination>
when starting the viewer, display the page of the document containing the named destination
(notes: not all viewers support this feature, and even in those cases this option only has effect
when the document is initially loaded).
-r, --reset_focus
after sending commands to the PDF viewer, attempt to reset the input focus to the window which
had focus before the commands were sent.
-viewer, --viewer <ar9|ar9-tab|ar8|ar7|ar5|xpdf|evince>
use (respectively) Adobe Reader 9 (in a new window), Adobe Reader 9 (in a new tab of a running
AR9, if any), Adobe Reader 8, Adobe Reader 7, Adobe Reader 5, xpdf or evince as the PDF viewer
program. Adobe Reader 9 (in a new window) is the default.
RATIONALE
At certain points of TeX document preparation, many people repeat a "edit-compile-view" cycle. Since PDF
viewers such as Adobe's Acrobat Reader ("acroread") do not automatically refresh the display when the PDF
file changes, this cycle can be more cumbersome than desired. The pdfopen program provides the ability
to automate the reloading of the PDF document when it is changed.
Note: there seems to be little need for pdfclose under GNU/Linux, since (unlike the situation for MS
windows) acroread does not lock the PDF file, which would prevent pdftex (or a DVI to PDF converter) from
creating a new version of the PDF output file. However, pdfclose is provided in case someone finds it
useful.
DESCRIPTION
pdfopen searches for an instance of the specified (or default) PDF viewer displaying the specified PDF
file. If there is already an instance of the given viewer displaying the given file, the viewer is
instructed to reload the file. If no such instance is found, pdfopen attempts to run the specified
viewer on the specified document.
The default viewer is "acroread", which could start any one of a number of versions of Acrobat Reader,
depending on what is installed on your system. However, the commands to reload the current document vary
from one version of acroread to another; consequently, if you are using a version of acroread other than
AR9, you should explicitly specify the viewer program.
This version of pdfopen accepts the following viewer options:
ar9, ar9-tab, ar8, ar7, ar5, xpdf, and evince.
The difference between ar9 and ar9-tab is significant when there is no instance of AR9 already displaying
the requested document. In this situation, while ar9 will request acroread to create a new instance of
acroread (and thus open a new window) by using the -openInNewInstance argument, ar9-tab starts acroread
without this argument; if there is already an instance of acroread running, a new tab will be opened in
an existing window.
pdfclose searches for one of the above PDF viewers displaying the given file and instructs the viewer to
"close" the window. In most cases, the PDF viewer continues to run, possibly now displaying just a blank
window. (This behaviour varies somewhat from one PDF viewer to another.)
PORTABILITY AND AVAILABILITY
These programs have been tested on Slackware64 Version 14.1 and a few other versions / distributions of
GNU/Linux. The code is reasonably generic and should work out of the box using most recent X11
implementations. (Reports to the contrary are welcome, particularly if they come with robust fixes.)
These programs are designed for X11-based systems. If you somehow find compiled versions of these
programs on a system using another window system, they are very unlikely to be of any use to you.
Source and binaries of the programs can be downloaded from CTAN://support/xpdfopen/ (e.g.,
http://mirror.ctan.org/support/xpdfopen).
CAVEATS
If you use ar9-tab to reload the PDF document and the instance of acroread with the given document is
currently displaying some other document, the command causes your document to be displayed, but not
reloaded.
pdfopen works by looking for a window with a name (window title) matching that expected for the given
viewer and document. If for some reason your viewer's window name is not as expected, pdfopen may not
work for you.
With at least AR9 and some window managers, using pdfopen to reload the document gives focus to the
acroread window, even though the mouse cursor is not necessarily in that window. This can be annoying.
The -reset_focus option can be used to deal with this problem.
AUTHOR
This manual page was written by Jim Diamond <Jim.Diamond@acadiau.ca>. I am the current maintainer of the
X11 versions of pdfopen and pdfclose. Report any bugs you find to me. Feature enhancement requests are
welcome, coded enhancements even more so.
Past authors: Fabrice Popineau wrote the MS-windows versions of pdfopen and pdfclose upon which these
programs were originally based. Taco Hoekwater created the GNU/Linux versions, up to Version 0.61
(including some documentation which inspired parts of this man page). Peter Breitenlohner has
contributed both code and suggestions to versions later than 0.61.
