DESCRIPTION
pdfroff
is a wrapper program for the GNU text processing system,
groff.
It transparently handles the mechanics of multiple pass
groff
processing, when applied to suitably marked up
groff
source files,
such that tables of contents and body text are formatted separately,
and are subsequently combined in the correct order, for final publication
as a single PDF document.
A further optional
``style sheet''
capability is provided;
this allows for the definition of content which is required to precede the
table of contents, in the published document.
For each invocation of
pdfroff,
the ultimate
groff
output stream is post-processed by the GhostScript interpreter,
to produce a finished PDF document.
pdfroff
makes no assumptions about, and imposes no restrictions on, the use of
any
groff
macro packages which the user may choose to employ,
in order to achieve a desired document format;
however, it
does
include specific built in support for the
pdfmark
macro package, should the user choose to employ it.
Specifically, if the
pdfhref
macro, defined in the
pdfmark.tmac
package, is used to define public reference marks, or dynamic links to
such reference marks, then
pdfroff
performs as many preformatting
groff
passes as required, up to a maximum limit of
four,
in order to compile a document reference dictionary, to resolve
references, and to expand the dynamically defined content of links.
USAGE
The command line is parsed in accordance with normal GNU conventions,
but with one exception --- when specifying any short form option
(i.e., a single character option introduced by a single hyphen),
and if that option expects an argument, then it
must
be specified independently (i.e., it may
not
be appended to any group of other single character short form options).
Long form option names (i.e., those introduced by a double hyphen) may
be abbreviated to their minimum length unambiguous initial substring.
Otherwise,
pdfroff
usage closely mirrors that of
groff
itself.
Indeed, with the exception of the
-h,
-v,
and
-T dev
short form options, and all long form options, which are parsed
internally by
pdfroff,
all options and file name arguments specified on the command line are
passed on to
groff,
to control the formatting of the PDF document.
Consequently,
pdfroff
accepts all options and arguments, as specified in
groff(1),
which may also be considered as the definitive reference for all standard
pdfroff
options and argument usage.
OPTIONS
pdfroff
accepts all of the short form options (i.e., those introduced by a
single hyphen), which are available with
groff
itself.
In most cases, these are simply passed transparently to
groff;
the following, however, are handled specially by
pdfroff.
- -h
-
Same as
--help;
see below.
- -i
-
Process standard input, after all other specified input files.
This is passed transparently to
groff,
but, if grouped with other options, it
must
be the first in the group.
Hiding it within a group breaks standard input processing, in the
multiple pass
groff
processing context of
pdfroff.
- -T dev
-
Only
-T ps
is supported by
pdfroff.
Attempting to specify any other device causes
pdfroff
to abort.
- -v
-
Same as
--version;
see below.
See
groff(1)
for a description of all other short form options, which are
transparently passed through
pdfroff
to
groff.
All long form options (i.e., those introduced by a double hyphen) are
interpreted locally by
pdfroff;
they are
not
passed on to
groff,
unless otherwise stated below.
- --help
-
Causes
pdfroff
to display a summary of the its usage syntax, and supported options,
and then exit.
- --emit-ps
-
Suppresses the final output conversion step, causing
pdfroff
to emit PostScript output instead of PDF.
This may be useful, to capture intermediate PostScript output, when
using a specialised postprocessor, such as
gpresent
for example,
in place of the default
GhostScript
PDF writer.
- --keep-temporary-files
-
Suppresses the deletion of temporary files, which normally occurs
after
pdfroff
has completed PDF document formatting; this may be useful, when
debugging formatting problems.
-
See section
FILES,
for a description of the temporary files used by
pdfroff.
- --no-pdf-output
-
May be used with the
--reference-dictionary=name
option (described below) to eliminate the overhead of PDF formatting,
when running
pdfroff
to create a reference dictionary, for use in a different document.
- --no-reference-dictionary
-
May be used to eliminate the overhead of creating a reference dictionary,
when it is known that the target PDF document contains no public
references, created by the
pdfhref
macro.
- --no-toc-relocation
-
May be used to eliminate the extra
groff
processing pass,
which is required to generate a table of contents,
and relocate it to the start of the PDF document,
when processing any document which lacks an automatically
generated table of contents.
- --no-kill-null-pages
-
While preparing for simulation of the manual collation step,
which is traditionally required to relocate of a
table of contents
to the start of a document,
pdfroff
accumulates a number of empty page descriptions
into the intermediate
PostScript
output stream.
During the final collation step,
these empty pages are normally discarded from the finished document;
this option forces
pdfroff
to leave them in place.
- --pdf-output=name
-
Specifies the name to be used for the resultant PDF document;
if unspecified, the PDF output is written to standard output.
A future version of
pdfroff
may use this option,
to encode the document name in a generated reference dictionary.
- --reference-dictionary=name
-
Specifies the name to be used for the generated reference dictionary file;
if unspecified, the reference dictionary is created in a temporary file,
which is deleted when
pdfroff
completes processing of the current document.
This option
must
be specified, if it is desired to save the reference dictionary,
for use in references placed in other PDF documents.
- --report-progress
-
Causes
pdfroff
to display an informational message on standard error,
at the start of each
groff
processing pass.
- --stylesheet=name
-
Specifies the name of an
input file,
to be used as a style sheet for formatting of content,
which is to be placed
before
the table of contents,
in the formatted PDF document.
- --version
-
Causes
pdfroff
to display a version identification message.
The entire command line is then passed transparently to
groff,
in a
one
pass operation
only,
in order to display the associated
groff
version information, before exiting.
ENVIRONMENT
The following environment variables may be set, and exported,
to modify the behaviour of
pdfroff.
- PDFROFF_COLLATE
-
Specifies the program to be used
for collation of the finished PDF document.
-
This collation step may be required to move
tables of contents
to the start of the finished PDF document,
when formatting with traditional macro packages,
which print them at the end.
However, users should not normally need to specify
PDFROFF_COLLATE,
(and indeed, are not encouraged to do so). If unspecified,
pdfroff
uses
sed(1)
by default,
which normally suffices.
-
If
PDFROFF_COLLATE
is
specified,
then it must act as a filter,
accepting a list of file name arguments,
and write its output to the
stdout
stream,
whence it is piped to the
PDFROFF_POSTPROCESSOR_COMMAND,
to produce the finished PDF output.
-
When specifying
PDFROFF_COLLATE,
it is normally necessary to also specify
PDFROFF_KILL_NULL_PAGES.
-
PDFROFF_COLLATE
is ignored,
if
pdfroff
is invoked with the
--no-kill-null-pages
option.
- PDFROFF_KILL_NULL_PAGES
-
Specifies options to be passed to the
PDFROFF_COLLATE
program.
-
It should not normally be necessary to specify
PDFROFF_KILL_NULL_PAGES.
The internal default is a
sed(1)
script,
which is intended to remove completely blank pages
from the collated output stream,
and which should be appropriate in most applications of
pdfroff.
However,
if any alternative to
sed(1)
is specified for
PDFROFF_COLLATE,
then it is likely that a corresponding alternative specification for
PDFROFF_KILL_NULL_PAGES
is required.
-
As in the case of
PDFROFF_COLLATE,
PDFROFF_KILL_NULL_PAGES
is ignored, if
pdfroff
is invoked with the
--no-kill-null-pages
option.
- PDFROFF_POSTPROCESSOR_COMMAND
-
Specifies the command to be used for the final document conversion
from PostScript intermediate output to PDF.
It must behave as a filter,
writing its output to the
stdout
stream,
and must accept an arbitrary number of
files ...
arguments,
with the special case of
-
representing the
stdin
stream.
-
If unspecified,
PDFROFF_POSTPROCESSOR_COMMAND
defaults to
-
-
- GROFF_TMPDIR
-
Identifies the directory in which
pdfroff
should create temporary files.
If
GROFF_TMPDIR
is
not
specified, then the variables
TMPDIR,
TMP
and
TEMP
are considered in turn, as possible temporary file repositories.
If none of these are set, then temporary files are created
in the current directory.
- GROFF_GHOSTSCRIPT_INTERPRETER
-
Specifies the program to be invoked, when
pdfroff
converts
groff
PostScript output to PDF.
If
PDFROFF_POSTPROCESSOR_COMMAND
is specified,
then the command name it specifies is
implicitly
assigned to
GROFF_GHOSTSCRIPT_INTERPRETER,
overriding any explicit setting specified in the environment.
If
GROFF_GHOSTSCRIPT_INTERPRETER
is not specified, then
pdfroff
searches the process
PATH,
looking for a program with any of the well known names
for the GhostScript interpreter;
if no GhostScript interpreter can be found,
pdfroff
aborts.
- GROFF_AWK_INTERPRETER
-
Specifies the program to be invoked, when
pdfroff
is extracting reference dictionary entries from a
groff
intermediate message stream.
If
GROFF_AWK_INTERPRETER
is not specified, then
pdfroff
searches the process
PATH,
looking for any of the preferred programs, [oq]gawk[cq],
[oq]mawk[cq], [oq]nawk[cq], and [ok]awk[cq], in this order; if
none of these are found,
pdfroff
issues a warning message, and continue processing;
however, in this case, no reference dictionary is created.
- OSTYPE
-
Typically defined automatically by the operating system,
OSTYPE
is used on Microsoft Win32/MS-DOS platforms
only,
to infer the default
PATH_SEPARATOR
character,
which is used when parsing the process
PATH
to search for external helper programs.
- PATH_SEPARATOR
-
If set,
PATH_SEPARATOR
overrides the default separator character,
([oq]:[cq] on POSIX/UNIX systems,
inferred from
OSTYPE
on Microsoft Win32/MS-DOS),
which is used when parsing the process
PATH
to search for external helper programs.
- SHOW_PROGRESS
-
If this is set to a non-empty value, then
pdfroff
always behaves as if the
--report-progress
option is specified, on the command line.
FILES
Input and output files for
pdfroff
may be named according to any convention of the user[aq]s choice.
Typically, input files may be named according to the choice of the
principal formatting macro package, e.g.,
file.ms
might be an input file for formatting using the
ms
macros
(
s.tmac);
normally, the final output file should be named
file.pdf.
Temporary files, created by
pdfroff,
are placed in the file system hierarchy,
in or below the directory specified by environment variables
(see section
ENVIRONMENT).
If
mktemp(1)
is available,
it is invoked to create a private subdirectory of
the nominated temporary files directory,
(with subdirectory name derived from the template
pdfroff-XXXXXXXXXX);
if this subdirectory is successfully created,
the temporary files will be placed within it,
otherwise they will be placed directly in the directory
nominated in the environment.
All temporary files themselves
are named according to the convention
pdf$$.*, where
$$
is the standard shell variable representing the process ID of the
pdfroff
process itself, and
*
represents any of the extensions used by
pdfroff
to identify the following temporary and intermediate files.
- pdf$$.tmp
-
A scratch pad file,
used to capture reference data emitted by
groff,
during the
reference dictionary
compilation phase.
- pdf$$.ref
-
The
reference dictionary,
as compiled in the last but one pass of the
reference dictionary
compilation phase;
(at the start of the first pass,
this file is created empty;
in successive passes,
it contains the
reference dictionary
entries,
as collected in the preceding pass).
-
If the
--reference-dictionary=name
option is specified,
this intermediate file becomes permanent,
and is named
name,
rather than
pdf$$.ref.
- pdf$$.cmp
-
Used to collect
reference dictionary
entries during the active pass of the
reference dictionary
compilation phase.
At the end of any pass,
when the content of
pdf$$.cmp
compares as identical to
pdf$$.ref,
(or the corresponding file named by the
--reference-dictionary=name
option),
then
reference dictionary
compilation is terminated,
and the
document reference map
is appended to this intermediate file,
for inclusion in the final formatting passes.
- pdf$$.tc
-
An intermediate
PostScript
file,
in which lq]Table of Contentsrq] entries are collected,
to facilitate relocation before the body text,
on ultimate output to the
GhostScript
postprocessor.
- pdf$$.ps
-
An intermediate
PostScript
file,
in which the body text is collected prior to ultimate output to the
GhostScript
postprocessor,
in the proper sequence,
after
pdf$$.tc.
SEE ALSO
See
groff(1)
for the definitive reference to document formatting with
groff.
Since
pdfroff
provides a superset of all
groff
capabilities,
groff(1)
may also be considered to be the definitive reference to all
standard
capabilities of
pdfroff,
with this document providing the reference to
pdfroff[aq]s
extended features.
While
pdfroff
imposes neither any restriction on, nor any requirement for,
the use of any specific
groff
macro package, a number of supplied macro packages,
and in particular those associated with the package
pdfmark.tmac,
are best suited for use with
pdfroff
as the preferred formatter.
Detailed documentation on the use of these packages may be found,
in PDF format, in the reference guide
``Portable Document Format Publishing with GNU Troff'',
included in the installed documentation set as
/usr/share/doc/groff-1.22.3/pdf/pdfmark.pdf.
