Hi,
I've sometimes wondered whether it might be profitable to modify
soelim and troff such that one might embed a filter script inside a
troff source file. So for example:
.SCRIPT-BEGIN sometag
#!/usr/bin/env python
"a useful and trivial script which translates chess pieces into
font changes and glyphs. This script is cut out by soelim and
saved safely to a temporary file somewhere."
.SCRIPT-END
normal troff text etc
.SCRIPT-INPUT-BEGIN sometag .\" following text is fed through the
rnbqkbnr .\" trivial script and its output is
pppppppp .\" placed here. This is run by troff
........ .\" in a similar way as .SY.
........ .\" The script is referenced by sometag
........ .\" and troff removes the script and
........ .\" any associated temporary files at
PPPPPPPP .\" the end of input.
RNBQKBNR
.SCRIPT-INPUT-END
I suspect the .SCRIPT-INPUT-BEGIN .SCRIPT-INPUT-END could be
implemented as macros which map onto a similar escape technique as the
suppression escapes \O etc. In any event the obvious advantage to
this approach is that one can harness the ability of a scripting
language to manipulate raw text rather than fight .tr et al and
diversions. It would also mean one could distribute filters hidden
inside macro sets. Potentially with mechanisms such as swig it might
be possible for, say Python to import more runtime information from
the troff parent. Which would be fun - and _might_ enable easier
experimentation with micro typography to take place, possibly. Or you
could include the knights tour program inside the troff source.
Of course this could all be regarded as several steps too far :-)
regards,
Gaius
