ZIF

ZIF, a Z-machine interpreter for interactive fiction. It's currently targeting version 5. It is VERY incomplete in it's current state.

Z-machines are an abstract machine with a flat memory space that use a hybrid of stack and register instruction operands.

Interactive fiction is a form of interactive media that takes input as a series of text commands. The commands are parsed and then used to modify the state of the fiction.

If you're thinking of implementing a Z-machine, it's very 70s. The design, all the the tooling. Maybe consider trying something more modern.

The source code is available from BitBucket.
