Development Kits

Development kits are complete distributions of Alan containing everything required to develop text adventures (or interactive fiction) with Alan. Development kits include at least both a compiler and an interpreter.

If you just want to play a game, you can find separate interpreters in the Interpreters download section.

You can supplement your SDK with the AlanIDE, extra documentation, extensions or utilities like the AlanGrapher.

If you want to keep up with the latest Alan development you can try the Development Snapshots.

Beta 3.0beta7

Released on:
Sunday, 06 September 2020 02:00
  • FEATURE: ellision/contraction marked by apostrophe (such as "l'aqua" in italian) is now handled so that it is first looked up as a complete word, but failing that will fallback and look for the two parts separated by the apostrophe as single words.
  • FEATURE: allow double conjunctions between player sentences, to allow such as "take the stone and then drop it". ("and" and "then" are both conjunctions).
  • BUGFIX: pack option did not work
  • BUGFIX: Random In Container sometimes crashed
  • BUGFIX: Grave accented 'E' ('è') was lost in syntaxes and synonyms
  • BUGFIX: It was possible to declare multiple pronouns but only the first one worked.
  • BUGIFX: System Error was thrown when using IN-filters and the container was a local variable.
  • BUGFIX: Division by zero crashed the interpreter, now it throws an Application Error instead.
  • BUGFIX: If the player input in a string parameter contained a dollar sign, it was expanded on output (or crashed).
