Adventure Writing for Everyone
Development Kits
Development kits are complete distributions of Alan containing everything required to develop text adventures or interactive fiction with Alan. It includes 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
- Released on:
- Wednesday, 21 September 2016 02:00

Beta 3.0beta4
- Maturity:
- Beta
- Released on:
- Friday, 14 March 2014 01:00
- MAJOR FEATURE: 'Indirectly' keyword to complement 'Directly In', allowing explicit transitivity of containment, see the manual
- FEATURE: The hero is now a container by default

Beta 3.0beta3
- Maturity:
- Beta
- Released on:
- Friday, 27 December 2013 01:00
- MAJOR FEATURE: the class of parameters and locals can now be asserted using If .. Isa .. allowing general restrictions in parameter restrictions and more specific access (attributes, scripts, containers) with the If-statement
- FEATURE: Attributes inherited from entity can now be referenced for literals
- FEATURE: Debugger now has a command to toggle a levels of trace off and on
- FEATURE: Debugger now lists the programmer name of instances as well as the player name
- FEATURE: Debugger can now list instances matching a wildcard pattern ("instance a*")

- BUGFIX: Out of memory error in interpreter for very large game fixed
- BUGFIX: sometimes locating a location At itself crashed the interpreter
- BUGFIX: comparing strings with '' did not work
- BUGFIX: using a location identifier as a direction sometimes caused a compiler crash
- BUGFIX: A DEBUG message could be printed in some games in some circumstances
Beta 3.0beta2
- Maturity:
- Beta
- Released on:
- Monday, 26 September 2011 02:00
- FEATURE: radically improved rules handling to simplify usage which changed the context in which rules execute (Current Location and Current Actor no longer allowed in rules)

- FEATURE: syntax may now start with a parameter (an instance, like an actor name)
- FEATURE: TRANSCRIPT statement in language
- FEATURE: PROMPT section in language to control player input prompt
- FEATURE: new debugger command language
- FEATURE: tracing can now use symbolic parameter names
- BUGFIX: if a dollar sign was followed by a character not defined as a printing symbol, that character was lost
- BUGFIX: sometimes events would not be restored correctly from a save file
- BUGFIX: positioning of error pointers in -cc mode was not always correct causing AlanIDE to point to the wrong place
- BUGFIX: sometimes WinArun and Gargoyle interpreters hung on
prompt - BUGFIX: undo after quit did sometimes crash
Alpha 3.0alpha9
- Maturity:
- Alpha
- Released on:
- Sunday, 03 October 2010 02:00
- FEATURE: Improved the tracing messages in the debugger
- BUGFIX: WinArun did not follow preferences for window colouring and fonts
- BUGFIX: WinArun did not find sound and image resources when started in another directory
- BUGFIX: a pronoun referencing an instance from a previous command that is no longer available, the message was non-optimal
- Clearified licensing, read COPYING
- Upgraded WinGLK to 1.39
Alpha 3.0alpha7
- Maturity:
- Alpha
- Released on:
- Monday, 30 June 2008 02:00
- BUG: "undo" as a response to "Quit?" undid the wrong command in some cases.
- BUG: verb bodies in outer nested locations did not get executed.
- Prohibited locating actors into containers.
- BUG: aggregating over things in restricted containers did not consider the class restriction so did not find e.g. attributes defined for that class.
- BUG: In loops with an "In
" filter this did not restrict the class to the classes taken by the container. - BUG: Isa expressions and loop filters did a general lookup for the class name, so would find e.g. default syntax parameters.
- BUG: WinArun could try to restore from an empty file reference in some cases.
- BUG: If a multiple or omnipotent indicator was used for one syntax which shared a common prefix (starting with the same verb e.g.) would sometimes miss the indicator. Changed this to make an indicator implicitly apply to all syntaxes with the same prefix.
- Extensive refactoring of the sources and Makefiles.
- Removed support for the Metrowerks (old Mac) compiler.
