Glulx

From IFWiki

Jump to: navigation, search

Glulx is a virtual machine designed by Andrew Plotkin which by default uses the Glk Application Programming Interface (API). The Inform language can compile bytecode for Glulx. It imposes far fewer limitations on game size than the Z-machine and offers the I/O features of Glk, allowing Inform programmers to write larger games with more complicated user interfaces, without having to learn another programming language.

Version History

  • 3.1.2: Added support for floating point arithmetic.
  • 3.1.1: Added support for function acceleration.
  • 3.1.0: Added support for block operations and heap memory allocation. Games using Inform 7's "indexed text" or "list" functionality require an interpreter that supports 3.1.0.
  • 3.0.0: Added Unicode support.
  • 2.0.0: Added modular I/O system system. The default I/O system is no longer Glk, which makes this an incompatible change.
  • 1.0.0: Previous versions were all called "1.0.0"

How to play Glulx games
