## pdfjam: A shell-script interface to the "pdfpages" LaTeX package ##
## ------ ##
## ##
## Author: David Firth (http://go.warwick.ac.uk/dfirth) ##
## ##
## Usage: see http://go.warwick.ac.uk/pdfjam or "pdfjam --help" ##
## ##
## Relies on: ##
## -- pdflatex ##
## -- the 'pdfpages' package for LaTeX (ideally version >= 0.4f) ##
## ##
## License: GPL version 2 or later. This software comes with ##
## ABSOLUTELY NO WARRANTY of fitness for any purpose at all; if you ##
## do not accept that, then you must not use it. ##
## ##
## The path searched for site-wide configuration files can be set ##
## by editing the following variable: ##
## ##
configpath='/etc:/usr/share/etc:/usr/local/share:/usr/local/etc' ##
## ##
## Nothing else in this file should need to be changed. ##
## ##
#########################################################################
##
## PRELIMINARIES
##
## First determine:
## --- whether verbose commentary should be provided (not if --quiet
# or --configpath was specified);
## --- whether this call to pdfjam is a "batch" call;
## --- whether just the help text is required;
## --- or whether all configuration files should be ignored.
##
verbose=true
for arg
do
case $arg in
--quiet | -q | --configpath)
verbose=false ;
;;
--version | -V)
echo "$version"
exit 0 ;
;;
--batch)
batch=true ;
;;
--help | -u | -h)
help=true ;
;;
--vanilla)
vanilla=true ;
;;
*)
;;
esac
done
##
## Check to see whether this is a "secondary" call to pdfjam:
##
if test -z "$PDFJAM_CALL_NUMBER" ## not a secondary call
then
PDFJAM_CALL_NUMBER=0
fi
##
## Keep a copy of the internal file separator, so we can change it safely
##
OIFS="$IFS"
##
## Record the full filename of the current working diractory
##
pwd=`pwd`
##
## Trap interrupts so that they kill everything:
##
trap 'IFS=$OIFS; exit 1' 1 2 9 15
##
## The following will be useful for readability of the script:
##
newline='
'
##
## Define a function to escape tricky characters in file names etc:
##
escape_chars () {
(printf "%s" "${1}" | sed 's/[^a-zA-Z0-9._/\-]/\\&/g')
}
##
## Define a function to output verbose comments:
##
prattle () { ## second argument here is non-null for continuation lines
if test $verbose = true; then
prefix1=" pdfjam:" ;
prefix2=`printf "%s" "$prefix1" | sed 's/pdfjam:/ /'` ;
indent="" ;
if test "$PDFJAM_CALL_NUMBER" -gt 0 &&
test "$batch" != true
then
indent=" "
fi
IFS="$newline" ;
lineCounter=0 ;
for line in ${1}
do
lineCounter=`expr $lineCounter + 1` ;
if test $lineCounter -eq 1 && test ! -n "${2}" ;
then
if test -w "$PDFJAM_MESSAGES_FILE"
then printf "$prefix1$indent %s\n" "$line" 1>/dev/null >> \
"$PDFJAM_MESSAGES_FILE"
else messages="$messages$prefix1$indent $line$newline"
## msg file not made yet
fi
else
if test -w "$PDFJAM_MESSAGES_FILE"
then printf "$prefix2$indent %s\n" "$line" 1>/dev/null >> \
"$PDFJAM_MESSAGES_FILE"
else messages="$messages$prefix2$indent $line$newline"
## msg file not made yet
fi
fi ;
done ;
IFS="$OIFS" ;

return ;
}
##
## And here's the first piece of verbose commentary:
##
prattle "----" 1
prattle "This is pdfjam version ${version}."

## CONFIGURATION
##
## THESE SETTINGS WILL BE OVER-RIDDEN by any found in configuration
## files. By default such files are found at any or all of
## /etc/pdfjam.conf
## /usr/share/etc/pdfjam.conf
## /usr/local/share/pdfjam.conf
## /usr/local/etc/pdfjam.conf
## $HOME/.pdfjam.conf
## (And they are read in that order; if a setting is made more than
## once, the last instance prevails.)
##
## An example configuration file can be found at
## http://go.warwick.ac.uk/pdfjam
##
## The path searched for site-wide configuration files can be changed
## by editing the variable 'configpath' at the top of this file.
##
##
## First check whether 'pdflatex' is in the user's path:
##
pdflatex=pdflatex
(hash pdflatex >/dev/null 2>&1) || pdflatex="not found"
##
##
## Likewise for the pdfinfo utility (only needed for `--keepinfo'):
##
pdfinfo='pdfinfo'
(hash pdfinfo >/dev/null 2>&1) || pdfinfo="not found"
##
##
## Next a permitted location for temporary files on your system:
##
#tempfileDir='/var/tmp' ## /var/tmp is standard on most unix systems
tempfileDir=${TMPDIR:-'/tmp'} ## /tmp is the default on Debian
##
##
## Default for the output file location:
##
outFile="$pwd" ## Output to the current working directory
##
##
## A few more default settings for pdfjam:
##
tidy='true' ## Delete all temporary files at the end
##
keepinfo='false' ## Don't try to preserve "pdfinfo" data
##
checkfiles='false' ## Don't use the Unix 'file -Lb' utility to
## identify PDF files from their contents;
## rely on the .pdf or .PDF extension instead.
##
suffix='pdfjam' ## Default filename suffix to be used when
## --outfile is either (a) a directory, or (b)
## not specified in a --batch call.
##
preamble='' ## Default LaTeX preamble string.
##
paper='a4paper' ## Default paper size is ISO A4.
##
## END OF SETTINGS MADE DIRECTLY WITHIN THE SCRIPT
##
## Now read the site's or user's configuration file(s) if such exist,
## unless '--vanilla' was specified.
##
if test "$vanilla" != true
then
if test "$PDFJAM_CALL_NUMBER" = 0 ## not a secondary call to pdfjam
then

## HELP TEXT
##
## Defines the output of 'pdfjam --help'
##
helptext="
pdfjam is a shell-script front end to the LaTeX 'pdfpages' package (for
which, see http://www.ctan.org/tex-archive/macros/latex/contrib/pdfpages).
Usage: pdfjam [OPTIONS] [--] [FILE1 [SEL1]] [FILE2 [SEL2]]...
where
* 'FILE1' etc. are PDF files (JPG and PNG files are also allowed). For
input from /dev/stdin, use the special name '/dev/stdin' in place of any
of FILE1, FILE2, etc: this can be mixed with 'real' files as needed, to
allow input through a pipe (note that if /dev/stdin is connected to tty,
an error results). If 'FILE1' is absent, pdfjam will use '/dev/stdin'
(and will use '-' for the page selection -- see next item).
* 'SEL1' is a page selection for FILE1, etc.
To select all pages (the default) use '-'. See the pdfpages manual for
more details. An example:
... file1 '{},2,4-5,9-' ...
makes an empty page, followed by pages 2,4,5,6 of file1, followed by pages
9 onwards (up to the end of file1).
A page selection can be applied to more than one file, e.g.,
... file1 file2 file3 1-7 ...
applies page selection '1-7' to all three files; but for example
... file1 file2 2- file3 1-7 ...
would apply the page selection '2-' to file1 and file2, and '1-7'
to file3. A page selection applies to all the files *immediately*
preceding it in the argument list. A missing page selection defaults to
'-'; this includes the case where 'FILE1' is absent and so /dev/stdin gets
used by default.
* 'options' are pdfpages specifications in the form '--KEY VALUE' (see
below), or
--help (or -h, or -u)
Output this text only; no processing of PDF files.
--configpath
Output the 'configpath' variable and exit immediately; no
processing of PDF files.
--version (or -V)
Output the version number of pdfjam and exit immediately; no
processing of PDF files.
--quiet (or -q)
Suppress verbose commentary on progress.
--batch
Run pdfjam sequentially on each input file in turn, and
produce a separate output file for each input, rather
than the default behaviour (which is a single run of
pdfjam on all of the input files, producing a single
output document). For the location of output
files, see '--outfile'. The --batch option cannot be
used in the case of input fron stdin.
--outfile PATH (or -o PATH)
Specifies where the output file(s) will go. If PATH is an
existing directory, pdfjam will attempt to write its
output PDF file(s) there, with name(s) derived from the
input file name(s) and the --suffix option (see below).
Otherwise the output file will be PATH. If '/dev/stdin'
is the only or last input file, PATH cannot be a directory.
Your current default PATH for output is:
$outFile
--suffix STRING
Specifies a suffix for output file names, to be used when
--outfile is either (a) a directory, or
(b) not specified in a --batch call.
A good STRING should be descriptive: for example,
--suffix 'rotated'
would append the text '-rotated' to the name of the input
file in order to make the output file name, as in
'myfile-rotated.pdf'. The STRING must not have zero
length.
[Default for you at this site: suffix=$suffix]
--checkfiles
--no-checkfiles
If the Unix 'file' utility is available, with options
-L and -b, the output of 'file -Lb FILE1' should be
'PDF document...' where '...' gives version information.
If this is the case on your system you should use
'--checkfiles'; otherwise use '--no-checkfiles',
in which case all input PDF files must have .pdf or .PDF
as their name extension.
[Default for you at this site: checkfiles=$checkfiles]
--preamble STRING
Append the supplied STRING to the preamble of the LaTeX
source file(s), immediately before the '\begin{document}'
line. An example:
pdfjam --nup 2x2 myfile.pdf -o myfile-4up.pdf \\
--preamble '\usepackage{fancyhdr} \pagestyle{fancy}'
The '--preamble' option can be used, for example, to load
LaTeX packages and/or to set global options. If '--preamble'
is used more than once in the call, the supplied preamble
strings are simply concatenated.
--keepinfo
--no-keepinfo
Preserve (or not) Title, Author, Subject and Keywords
(from the last input PDF file, if more than one) in the
output PDF file. This requires the pdfinfo utility, from
the xpdf package, and the LaTeX 'hyperref' package; if
either of those is not available, '--keepinfo' is ignored.
[Default for you at this site: keepinfo=$keepinfo]
--pdftitle STRING
--pdfauthor STRING
--pdfsubject STRING
--pdfkeywords STRING
Provide text for the Title, Author, Subject and Keywords
in the output PDF file. Requires the LaTeX 'hyperref'
package. These options, individually, over-ride --keepinfo.
--landscape
--no-landscape
Specify landscape page orientation (or not) in the
output PDF file.
[Default for you at this site: landscape=$landscape]
--twoside
--no-twoside
Specify (or not) the 'twoside' document class option.
[Default for you at this site: twoside=$twoside]
--paper PAPERSPEC (or simply --PAPERSPEC)
Specify a LaTeX paper size, for example
'--paper a4paper' or simply '--a4paper' for ISO A4 paper.
If the LaTeX 'geometry' package is installed, a wider range
of paper sizes is available. For details see documentation
for LaTeX and/or the 'geometry' package.
[Default for you at this site: paper=$paper]
--papersize '{WIDTH,HEIGHT}'
Specify a custom paper size, e.g.,
--papersize '{10in,18cm}'
(Note the braces, and the comma!)
If the 'geometry' package is not found, this has no effect.
--pagecolor RGBSPEC
Specify a background colour for the output pages. The
RGBSPEC must be a comma-separated trio of integers
between 0 and 255. An example:
--pagecolor 150,200,150
[Default is no background colour]
--tidy
--no-tidy
Specify whether the temporary directory created by
pdfjam should be deleted. Use '--no-tidy' to help debug
most errors.
[Default for you at this site: tidy=$tidy]
--vanilla
Suppress the reading of any site-wide or user-specific
configuration files.
--KEY VALUE
Specify options to '\includepdfmerge', in the LaTeX
'pdfpages' package. Here KEY is the name of any of the
many options for '\includepdfmerge', and VALUE is a
corresponding value. Examples are
--nup 2x1 (for 2-up side-by-side imposition)
--scale 0.7 (to scale all input pages to 70% size)
--offset '1cm 0.5cm'
(to offset all pages -- note the quotes!)
--frame true (to put a frame round each input page)
--trim '1cm 2cm 1cm 2cm' --clip true
(to trim those amounts from left, bottom,
right and top, respectively, of input
pages)
etc., etc. For more information see the manual for
the 'pdfpages' package, at
http://www.ctan.org/tex-archive/macros/latex/contrib/pdfpages
* '--' can be used to signal that there are no more options to come.
Defaults for the options '--suffix', '--keepinfo', '--paper', '--outfile',
'--landscape', '--twoside', '--tidy', '--checkfiles' and '--preamble' can be
set in site-wide or user-specific configuration files. The path that is
searched for site-wide configuration files (named pdfjam.conf) at this
installation is
$configpath
This configuration path can be changed by editing the pdfjam script if
necessary. Any user-specific configuration should be put in a file named
.pdfjam.conf in your home directory. (All of these files are ignored
if the '--vanilla' argument is used.)
For more information, including an example configuration file, see
http://go.warwick.ac.uk/pdfjam.
