[lojban] My parser and ZOI

[Robin Lee Powell <lojban-out@lojban.org>]

I've decided that having a pre-processor just to handle ZOI wasn't
compromising my principles too badly.  The entire pre-processor is as
follows:


- cut -

#!/bin/sh

cd /home/rlpowell/www/hobbies/lojban/grammar/rats

cat - | \
perl -p -e "s/(zoi[\s.]+|la'o[\s.]+)([a-zA-Z']+)([\s.]+.*[\s.]+)(\2)([\s.]+|\z)/\1QZOIMARKER\2\3\4\5QZOIMARKER/" | \
/usr/local/java/bin/java xtc/parser/PParser /dev/stdin

- cut -

The perl isn't nearly as bad as it looks; there's nothing there that
egrep can't do, except for the replacement and \z.

What this does is replace[1] the zoi boundary word (i.e. gy in "zoi gy
whee! gy") with the string QZOIMARKER.  That string was chosen to be
descriptive.  The Q is there to make sure it's not valid Lojban, so that
the pre-processor's efforts can never be mis-construed as valid for some
reason other than processing ZOI correctly.

[1]:  Technically, it prepends it in front of the first boundary word
and postpends it after the second; this is so that the entire original
text is recoverable.
