Hfst is a compiler for finite state transducers. The best documentation for writing such transducers is still Beesley and Karttunen (2003): Finite State Morphology. There still are some important differences between Hfst and the compilers described in the B&K book.


The Hfst subprograms

Hfst consists of a large number of smaller programs, with different functions:
