PassiveTeX

March 2003
## Summary PassiveTeX is a library of TeX macros which can be used to process an XML document which results from an XSL transformation to formatting objects. PassiveTeX provides a rapid development environment for experimenting with XSL FO, using a reliable pre-existing formatter Running PassiveTeX with the pdfTeX variant of TeX generates high-quality PDF files in a single operation. PassiveTeX shows how TeX can remain the formatter of choice for XML, while hiding the details of its operation from the user. ## How does it work? PassiveTeX relies heavily on work by David Carlisle (his namespace-aware XML parser written in TeX, `xmltex`), and was developed from my JadeTeX macros for processing DSSSL via Jade. Taking the XML version of the TEI Lite guidelines (teiu5.xml, with DTD teixlite.dtd), we apply an XSL stylesheet (see my page of TEI style sheets), and run it through Mike Kay's Saxon XSL processor:
      java com.icl.saxon.StyleSheet -o teiu5.fo teiu5.xml tei.xsl
(assuming you have `saxon.jar` and `sax.jar` on your CLASSPATH). This creates the new XML file teiu5.fo. We now run XMLTeX on this
     pdfxmltex teiu5.fo
which creates teiu5.pdf. Voila! Actually, we need to do
     pdfxmltex teiu5.fo
1. again, to resolve page-number references in the table of contents. For a comparison with an HTML rendering of the same document (using XSL again), see teiu5.html on the TEI pages. ## Installation The PassiveTeX macros should be downloaded (as a ZIP file, passivetex.zip), unpacked, and installed in a TeX system (eg in `texmf/tex/latex/passivetex`) in the normal place where you put macros. Consult your local documentation or local expert if you do not know how to install a new package; on a web2c-based system, don't forget to run `mktexlsr` when you have the files in place, to update the file lookup table. What about that `pdfxmltex` command we saw in the last section? You don't have it on your system? You need to download xmltex from CTAN and install it in the your TeX system. It too is just a set of TeX macro packages. IMPORTANT NOTE. You need a copy of xmltex.tex latex than 2001/11/30. Now you can use xmltex on a file called (eg) `teiu5.fo` in one of two ways: Build an `xmltex` format file for pdfTeX with
       pdftex -ini "&pdflatex" pdfxmltex.ini
   and process your file with
       pdflatex "&pdfxmltex" teiu5.fo
   The command `pdfxmltex` used above is just a script which does
       tex -fmt=pdfxmltex -progname=pdfxmltex
2. Or, Make a wrapper file called (eg) `teiu5.tex` looking like this:
       \def\xmlfile{teiu5.fo}
       \input xmltex
   and run pdfTeX on it as normal with
       pdflatex teiu5.tex
Do not worry, `xmltex` knows how to find the PassiveTeX macros as it needs them. You will likely need to increase TeX memory values (in the file `texmf.cnf` if you use a Web2c-based TeX); I use:
    main_memory = 2500000
    param_size = 1500
    stack_size = 1500
    hash_extra = 50000
    string_vacancies = 45000
    pool_free = 47500
    nest_size = 500
    save_size = 10000
    pool_size = 500000
    max_strings = 55000
- For reference, the PassiveTeX package consists of the following files: The core xmltex `style' files for XSL FO XML:
       fotex.xmt
       fotex.sty
- Support for direct formatting of TEI XML with xmltex
       tei.xmt
       teixml.sty
- Some support files, shared with JadeTeX:
       unicode.sty
       ucharacters.sty
       mlnames.sty
       dummyels.sty
       nomulticol.sty
NOTE: TeX has a limit on the length of line it can read, and some .fo files you generate may cause TeX to die with an message about increasing buf_size. If you get that, edit your `texmf.cnf` file, increase the size of `buf_size` (mine is 200000), and remake any format files. ### LaTeX package dependencies This setup assumes you have a decent modern TeX setup. The TeX Live 6 CD-ROM is what I use, and it is up to date (see http://www.tug.org/texlive/).

## Notes on conformance to the XSL specification The following general limitations apply to most of the PassiveTeX implementation of XSL FO: The `px' unit is not recognised Absolute dimensions always work, but proportional ones are often not recognized The functions allowed in attribute values are usually not recognized There is no error checking at all, and all properies are recognized; do not assume that they do anything... Most of the formatting objects are implemented more or less; the following are not implemented at all: `fo:bidi-override` `fo:color-profile` `fo:declarations` `fo:initial-property-set` `fo:instream-foreign-object` `fo:multi-case` `fo:multi-properties` `fo:multi-property-set` `fo:multi-switch` `fo:multi-toggle` `fo:region-end` `fo:region-start` `fo:table-footer` ### Properties needed for basic conformance

## Sample files The TEI Lite description (teiu5.xml) converted PDF as teiu5.pdf A TEI test file (exercise.xml) converted to PDF as exercise.pdf A physics paper (teimath.xml) containing a fair amount of MathML markup, originally translated from LaTeX into XML. It is used extensively as an example in the LaTeX Web Companion. Here we see it converted to teimath.pdf using test/teimath.xsl James Tauber prepared a simple XSL spec (darkness.xsl) for Joseph Conrad's Heart of Darkness, which I ran to PDF as darkness.pdf ## Concerns and problems Some points to bear in mind This is an experimental system to check whether the idea works. Expect something more polished eventually. You need a modern TeX setup (like teTeX or TeX Live) to get to grips with it. Quite a few flow objects and characteristics are not dealt with yet. I will add support for more things as needed or requested. I do not have any objective check that what I think XSL FOs are supposed to do is actually right :-} I have only worked so far with the TEI Lite (XML version) and Docbook DTDs, and probably misinterpreted half of what they say. ## Things for LaTeX users to remember No use is made of LaTeX high-level constructs. No sections, no lists, no cross-refs, no bibliographies; on the other hand, some extensions in the `fotex:` namespace are supported (eg to get Acrobat bookmarks) XSL FO's underlying character set is Unicode; by default, entities are mapped to their Unicode position; All vertical and horizontal space is explicit in the specification Page and line breaking is left to TeX: the rest is up to you. ## Future directions Complete the MathML handling Handle more variety in property values (eg colors, fonts) Deal with more complex tables Support SVG. How? By direct intepretation and mapping to raw PDF By translation to MetaPost, and spawning a MetaPost process By pre-processing to existing TeX graphics languages In any case, SVG fragments need to be recognized directly to perform in-line graphical functions (setting text at an angle?) Use Unicode-based TeX variant (Omega) to handle non-Latin material more naturally I will be very glad to discuss details with anyone. Contact me (Sebastian Rahtz) as sebastian.rahtz@oucs.ox.ac.uk
