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 different 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 areinstalled. The list includes:
- •
- the ISO character entities for SGML
- •
- James Clark's DSSSL engine, jade, or an equivalent parserlike OpenJade
- •
- the DocBook DTD from the OASIS consortium
- •
- Norman Walsh's DocBook modular style sheets (or some otherset of DSSSL style sheets)
- •
- Sebastian Rahtz's jadetex set of TeX macros for jade(for backends intended to "printing" formats like PDF, RTF orPostScript)
- •
- A perl interpreter (for backends that use perl)
- •
- SGMLSpm from CPAN (for backends that use sgmls)
- •
- 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 convertsfrom DocBook (the default frontend) to HTML (the default backend),does not put the result in a subdirectory (unless specifiedotherwise 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 extensionsfor 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 canuse 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 convert from another input format.
This sample command creates one or many HTML files witharbitrary file names in the current directory. This default behaviorcan be changed through command line options and/or customizationstyle 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'sstyle sheets. This frontend searches in thesubdirectories of the base SGML directory for afile named html/docbook.dsl or print/docbook.dsl (depending on the backend's type: html or print).
- -b backend | --backend backend
- Allows to specify another backend than defaultHTML. The list of currently available backends is:
- dvi
- Converts to DVI (DeVice Independantfiles) by calling Jade or OpenJade.
- html
- Converts to HTML (HyperText MarkupLanguage) by calling Jade or OpenJade.
- man
- Converts a refentry to a Unix manual pageby calling docbook2man. Does not work with other SGMLdocument types than DocBook.
- Converts to PDF (Portable DocumentFormat) by calling Jade or OpenJade.
- ps
- Converts to PostScript bycalling 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 callingdocbook2texi. Does not work with other SGML document typesthan DocBook.
- txt
- Converts to a bare text fileby calling Jade or OpenJade, then Lynx.
- -c file | --cat file
- Allows to use an extra SGML Open Catalog that will listother files like customization style sheets, adaptations to theDocBook Document Type Definition, special character entities,etc. This catalog is added to the list of catalogs determinedby the script (see option --nostd below)
- -n | --nostd
- Do not use the standard SGML Open Catalogs. Normally,the standard catalogs list is determined like this:
- •
- if the centralized catalog exists, thenuse it. The centralized catalog is a list of allcatalogs that might be necessary that usuallyresides in /etc/sgml. Its name is provided by the frontend, for example the docbook frontend returns /etc/sgml/sgml-docbook.cat.
- •
- Otherwise, take all the filesnamed catalog from the subdirectories of the SGML base directory (usually /usr/share/sgml).
- -d file|default|none | --dsl file|default|none
- Allows to use a customized style sheet insteadof the default one.
A "target" starting with a hash mark "#" can be appendedto the file name. As a result, only the corresponding partof the style sheet is executed (the "style specification" whose"identificator" is equal to the target's name). A common use of thismechanism is to define "#html" and "#print" targets to triggerthe corresponding part of a replacement style sheet which iscommon for both HTML and printout conversion.
By replacing the file name with "default", the defaultstyle sheet provided with the frontend is used. For example, thedocbook frontend returns ./docbook.dsl#html (or ./docbook.dsl#print) in the SGML base directory.
By replacing the file name with "none", no replacementstyle sheet is used, not even the default style sheet. The stylesheet which is used is also determined by the frontend. Forexample, the docbook frontend returns Norman Walsh's html/docbook.dsl (or print/docbook.dsl) found somewhere below the SGML base directory.
If no --dsl option is specified, then "--dsl default" isused.
- -l file | --dcl file
- Allows to use a customized SGML declaration insteadof the default one. The file name of the default SGMLdeclaration is not set for SGML files, and is set toxml.dcl in the SGML base directory for XML files.
- -s path | --sgmlbase path
- Allows to use another location for the SGML basedirectory. This is the directory below which all SGML DTDs,style sheets, entities, etc are installed. The default valueis /usr/share/sgml.
- -p program | --parser program
- Specify the parser to use (Jade or OpenJade) if several are installed. 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 willbe stored. If the style sheets define a subdirectory where tostore the resulting files too, the subdirectory defined by thestyle sheets will be placed below the subdirectory defined bythis option.
- -V variable=[value]
- Set a variable (to a value, if one is specified).
- -u | --nochunks
- Output only one big file. This option is useful onlywhen generating HTML, because the output can be split intoseveral files. This option overrides the setting that may bedone in the style sheets.
- -i section | --include section
- Declare a SGML marked section as "include". A SGML markedsection is a kind of conditional part of a document. If it isdeclared "ignore", it will be left ignored, otherwise it willbe 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.Warning types that start with
"no-" disable the correspondingwarnings, the other types enable
them.
If the warning type is replaced with "list", thena list of allowed warning types is displayed.
- -e type|list | --error type|list
- Disables given types of errors.Several -e options might be entered on the
command line.All error types start with "no-".
If the error type is replaced with "list", thena list of allowed error types is displayed.
- -h | --help
- Print a short help message and exit
- -v | --version
- Print the version identifier and exit
