Would it be possible for the MySQL specific highlighter to extend a general SQL highlighter, making it possible for people to simply extend the core SQL standard highlighter for things like Postgre and Oracle as well?

If take a more close look at the package, you'll find out that creating a new highlighter is just a process of describing the highlighting rules in XML format. One could take the XML for general SQL and edit it to conform standards of a certain SQL dialect. That is really simple. At the moment I don't see any reason to implement any kind of inheritance. If you know such a reason, please let me know,

I guess it sounds tidy enough then, I'm just sucker for code reuse, which this seems like a good place to use it - if 90%+ of the highlighting rules will be the same, then it makes sense to me to keep that 90% in one file, which can be fixed in the future for everything. How about being able to include other highlighter definitions within the XML?

How often do programming languages change their syntax? I think making some edits and copy/pastes once within a year is not a problem :) -- Andrey Demenev aka Blindman demenev@on-line.jar.ru
