Finally, as a taster of the work we are doing, I have performed some rather unscientific and arbitrary performance tests on a 20Mb VRML 1.0 file. The performance of flex, Spirit, and our new library are as follows:
flex: < 1 second new library: about 1 second Spirit: 40-50 seconds.
Would you please post the grammar productions you used for Spirit? Would you consider testing the yard parser as well, http://yard-parser.sf.net ? Are there other advantages of your tool over Flex, other than providing a nice interface to Spirit? Christopher Diggins http://www.cdiggins.com http://www.heron-language.com
