John,
Yes, I think this regexp is usable in xot as well. I'll implement it and
will test it.
With regards to your second remark, my vote would be not to do this,
because the way plurals are formed is different from language to language.
Regards,
Tom

It also only uses a single glossary term and 3 capture groups to capture the before and after parts (which may be nothing - using the ^ and $) and the actual term (so that we maintain the case). It also handles some punctuation (this can easily be expanded upon). This means that it may even be suitable for xot also.

> Thanks for looking into this John. I'm just looking at the code you sent and you're right it doesn't take punctuation into account. It works when the word is at the beginning or end of a sentence, with or without a space immediately before or after but whenever there's punctuation next to it (cat. cat? etc.) it just gets replaced with cat and the punctuation is lost. Also, longer words that start with a word from the glossary get replaced with the shorter glossary word (e.g. category becomes cat).

>> Great to meet you all and I've been looking through the xenith code to see where I can contribute. Also, have been looking through the archives and came across the regexp problem for the glossary. Since i'm only today on the list proper not sure whether a reply will go through to the correct place so sending to you all to see if it helps...
>>
>> Not sure whether this has been fixed yet but it seems the problem is partly caused by /b requiring a word boundary and there being no word boundary on the very first word. Also, seem to remember somewhere that /b can in some cases match international characters in the middle of words which might not be the desired effect...
