javatex – A Java implementation of TeX
At root, this is a ‘small’ TeX (memmax=64K), but a larger version may be built.
The implementation was in essence an experiment, and performance proved so poor that the author considers it unusable in practice.
Maybe you are interested in the following packages as well.
- nts: New Typesetting System
- parsitex: A localized Persian and bidirectional extension of TeX
- tex: A sophisticated typesetting engine
- tex-fpc: A collection of change files for a TeX system based on Free Pascal
