DESCRIPTION
The jw shell script allows to convert a DocBook file (or some other
SGML-based format) to other formats (including HTML, RTF, PS and PDF)
with an easy-to-understand syntax. It hides most of Jade's or OpenJade
complexity and adds comfortable features.
Other scripts like docbook2html, docbook2rtf or docbook2ps provide dif-
ferent ways of calling jw that might be easier to remember.
For the moment, jw does not handle XML, but only SGML.
This utility assumes that several other components are installed. The
list includes:
o the ISO character entities for SGML
o James Clark's DSSSL engine, jade, or an equivalent parser like Open-
Jade
o the DocBook DTD from the OASIS consortium
o Norman Walsh's DocBook modular style sheets (or some other set of
DSSSL style sheets)
o Sebastian Rahtz's jadetex set of TeX macros for jade (for backends
intended to "printing" formats like PDF, RTF or PostScript)
o A perl interpreter (for backends that use perl)
o SGMLSpm from CPAN (for backends that use sgmls)
o Lynx HTML browser (for the txt backend)
The jw script is basically called like this:
jw mydoc.sgml
where mydoc.sgml is a SGML file.
The command line above uses default options: it converts from DocBook
(the default frontend) to HTML (the default backend), does not put the
result in a subdirectory (unless specified otherwise in the style
sheets), etc.
In this example, the "mydoc" file name as well as the ".sgml" extension
can be replaced by anything else. Current extensions for SGML DocBook
files include ".sgml", ".sgm", ".docbook", and ".db". The processed
file mydoc.sgml can be in any other directory than the current one.
Here we have chosen to generate HTML output. In fact we can use any of
the backends stored in the backends/ subdirectory of the DocBook-utils
distribution directory (usually /usr/share/docbook-utils). Similarly,
you can use any frontend defined in the frontends/ subdirectory to con-
vert from another input format.
This sample command creates one or many HTML files with arbitrary file
names in the current directory. This default behavior can be changed
through command line options and/or customization style sheets.
OPTIONS
The following options apply to the conversion script:
-f frontend | --frontend frontend
Allows to specify another frontend than default docbook. The
list of currently available frontends is:
docbook
Converts docbook with Norman Walsh's style sheets. This
frontend searches in the subdirectories of the base SGML
directory for a file named html/docbook.dsl or print/doc-
book.dsl (depending on the backend's type: html or
print).
-b backend | --backend backend
Allows to specify another backend than default HTML. The list of
currently available backends is:
dvi Converts to DVI (DeVice Independant files) by calling
Jade or OpenJade.
html Converts to HTML (HyperText Markup Language) by calling
Jade or OpenJade.
man Converts a refentry to a Unix manual page by calling doc-
book2man. Does not work with other SGML document types
than DocBook.
pdf Converts to PDF (Portable Document Format) by calling
Jade or OpenJade.
ps Converts to PostScript by calling Jade or OpenJade.
rtf Converts to RTF (Rich Text Format) by calling Jade or
OpenJade. The resulting file can then be inported into MS
Word or one of its Linux replacement programs.
tex Converts to TeX by calling Jade or OpenJade.
texi Converts to GNU TeXinfo pages by calling docbook2texi.
Does not work with other SGML document types than Doc-
Book.
txt Converts to a bare text file by calling Jade or OpenJade,
then Lynx.
-c file | --cat file
Allows to use an extra SGML Open Catalog that will list other
files like customization style sheets, adaptations to the Doc-
Book Document Type Definition, special character entities, etc.
This catalog is added to the list of catalogs determined by the
script (see option --nostd below)
-n | --nostd
Do not use the standard SGML Open Catalogs. Normally, the stan-
dard catalogs list is determined like this:
o if the centralized catalog exists, then use it. The central-
ized catalog is a list of all catalogs that might be necessary
that usually resides in /etc/sgml. Its name is provided by the
frontend, for example the docbook frontend returns
/etc/sgml/sgml-docbook.cat.
o Otherwise, take all the files named catalog from the subdirec-
tories of the SGML base directory (usually /usr/share/sgml).
This option is useful in conjunction with the --cat option to use only
the catalogs that are specified on the command line.
-d file|default|none | --dsl file|default|none
Allows to use a customized style sheet instead of the default
one.
A "target" starting with a hash mark "#" can be appended to the
file name. As a result, only the corresponding part of the style
sheet is executed (the "style specification" whose "identifica-
tor" is equal to the target's name). A common use of this mecha-
nism is to define "#html" and "#print" targets to trigger the
corresponding part of a replacement style sheet which is common
for both HTML and printout conversion.
By replacing the file name with "default", the default style
sheet provided with the frontend is used. For example, the doc-
book frontend returns ./docbook.dsl#html (or ./doc-
book.dsl#print) in the SGML base directory.
By replacing the file name with "none", no replacement style
sheet is used, not even the default style sheet. The style sheet
which is used is also determined by the frontend. For example,
the docbook frontend returns Norman Walsh's html/docbook.dsl (or
print/docbook.dsl) found somewhere below the SGML base direc-
tory.
If no --dsl option is specified, then "--dsl default" is used.
-l file | --dcl file
Allows to use a customized SGML declaration instead of the de-
fault one. The file name of the default SGML declaration is not
set for SGML files, and is set to xml.dcl in the SGML base di-
rectory for XML files.
-s path | --sgmlbase path
Allows to use another location for the SGML base directory. This
is the directory below which all SGML DTDs, style sheets, enti-
ties, etc are installed. The default value is /usr/share/sgml.
-p program | --parser program
Specify the parser to use (Jade or OpenJade) if several are in-
stalled. If this option is not specified, the script first tries
to use Jade, then it tries OpenJade.
-o directory | --output directory
Set output directory where all the resulting files will be
stored. If the style sheets define a subdirectory where to store
the resulting files too, the subdirectory defined by the style
sheets will be placed below the subdirectory defined by this op-
tion.
-V variable=[value]
Set a variable (to a value, if one is specified).
-u | --nochunks
Output only one big file. This option is useful only when gener-
ating HTML, because the output can be split into several files.
This option overrides the setting that may be done in the style
sheets.
-i section | --include section
Declare a SGML marked section as "include". A SGML marked sec-
tion is a kind of conditional part of a document. If it is de-
clared "ignore", it will be left ignored, otherwise it will be
processed. An example of such a marked section would be:
<DOCTYPE mydoc [
<!ENTITY % confidential "ignore">
]>
<mydoc>
...
<![ %confidential [ Some confidential text... ]]>
...
</mydoc>
-w type|list | --warning type|list
Enables or disables the display of given types of warnings.
Several -w options might be entered on the command line. Warn-
ing types that start with "no-" disable the corresponding warn-
ings, the other types enable them.
If the warning type is replaced with "list", then a list of al-
lowed warning types is displayed.
-e type|list | --error type|list
Disables given types of errors. Several -e options might be en-
tered on the command line. All error types start with "no-".
If the error type is replaced with "list", then a list of al-
lowed error types is displayed.
-h | --help
Print a short help message and exit
-v | --version
Print the version identifier and exit
