Sorry to hijack this thread, for a potential development discussion. Since I first saw this technique, in Tadziu's own `tmac.diss' documentation, I've been toying with ideas on how I might adapt it for `pdfroff'. I'd actually like to engineer the concept directly into groff itself. Here's how I think that might be achieved:-- 1) Define a new `command', in the troff intermediate output command set, or adapt one of those already existing, to mark collation points with arbitrary collating sequence serialisation indices. 2) Adapt troff's `\X' escape mechanism, so as to accommodate embedding of such collating marks into the troff output stream, at strategic points defined within the document source. 3) Provide a new intermediate postprocessor, (call it `grocol' perhaps?), which would read the troff output stream, split it at the embedded collating marks, then reassemble it in correctly collated sequence order, passing this on as its own output, to the ultimate device postprocessor. 4) Modify the groff program itself, to insert this `grocol' postprocessor between troff and the ultimate processor, in the normal processing pipeline; this would be activated by a new command line switch. I'd be willing to work on such an implementation, in parallel with ongoing development of `pdfroff' and `pdfmark.tmac', if there is any interest in pursuing the concept further. Any thoughts?
