• FEATURE: UTF-8 encoding is now supported for source, solution and transcript files. This extends support for non-English languages. The new compiler option -encoding will make the compiler assume that the source code is encoded with UTF-8. In addition, import files that have a UTF-8 BOM marker will always be read using UTF-8 encoding, irrespective of any options. The interpreter switch -u will indicate that input and output in the terminal, command logs, transcript files and solution files, is performed using UTF-8 encoding (which is the default on Linux and becoming more common). See Appendix C in The Alan Language Manual for details.
  • FEATURE (language): Block comments. See chapter 4, Lexical Definitions in the Alan Language Manual
  • FEATURE (interpreters): Make it possible to generate transcript and command logs simultaneously from a single game run
  • FEATURE (misc): Ensure Alan complies with the Babel Treaty (a convention to make it possible to identify and catalog *all* works of Interactive Fiction)
  • FEATURE (interpreter): Add separate option for not paging output ("<More>")
  • WARNING: warn for actors in containers as the behaviour is not completely well-defined
  • BUGFIX: When an item is located in a container the limits now considers content in possibly contained items recursively. Furthermore, if the container in itself is inside a container with limits those limits are also checked. This might change behaviour of existing games, please check by running your tests.
  • BUGFIX: Large games with many string or set manipulations could sometimes exhibit significant slowdowns over time
  • BUGFIX: Transcript was always empty when started from code using "Transcript On."
  • BUGFIX: Random spacing issues fixed
  • BUGFIX: Dynamic variable $v gave wrong output if used in Exits
  • BUGFIX: Dynamic variable $o crashed the interpreter if used in an Exit
  • BUGFIX: Option section did not allow you to use 'no' before a boolean option

What They Say

"[the game] does not represent the real capabilities of the Alan Language but does demonstrate Alan's amazing ability to allow someone who has never done an iota of computer programming of any kind to produce SOMETHING within a few weeks!"
