v0.3.0 - 15 March 2022

Changed

• All endpoints are now prefixed by /api. This allows us to control the routes better in the web interface. (#83)

• Web development & build environment migrated from vue-cli to vite. It is faster & reduces our dependencies. (#84)

• Convert web interface to use TypeScript. (#86)

• Update vanilla ACT-R to version 7.27.0 (from 15 Sep 2021).

• Change underlying ccm code from CCMSuite3 to python_actr. The python_actr code was extracted from CCMSuite3 and now has a pip package to make installation easier.

  • Naming note: When gactar was written, it used CCMSuite3 and it was referred to throughout gactar as ccm. Instead of changing everything to refer to python_actr I've decided to leave it as ccm. This helps avoid confusion between python_actr and pyactr.

• Update all underlying dependencies (both go and npm).

v0.2.0 - 17 November 2021

Added

• Added optional authors field to the model section. (#54) It is a list of strings.

  Example:

  authors {
   	'Andy Maloney <[email protected]>'
   	'Hiro Protagonist <[email protected]>'
  }
  

• Generated source files now include the gactar version which was used to generate them in the comments at the top. (#78)

• Added new web API endpoints for creating sessions, and compiling & running models. These are intended to be used by other software to compile and run amod models using gactar running as a server. See the Web API documentation for details.

• Added documentation for existing web endpoints.

Changed

• Unused variables now produce an error. (#58)

  ERROR: variable ?blat is not used - should be simplified to '?' (line 9)
  

• Anonymous variables ("?") in set statements now produce an error. (#59)

  do {
    set goal.thing to ?
    set goal to [foo: ?]
  }
  

  This will result in:

  ERROR: cannot set 'goal.thing' to anonymous var ('?') in production 'start' (line 10)
  

• Anonymous variables ("?") in print statements now produce an error. (#60)

  do {
    print ?
  }
  

  This will result in:

  ERROR: cannot print anonymous var ('?') in production 'start' (line 9)
  

• Compound variables ("?foo!?bar") in set statements now produce an error. (#63)

  do {
    set goal to [foo: ?foo!?bar]
  }
  

  This will result in:

  ERROR: cannot set 'goal.thing' to compound var in production 'start' (line 10)
  

• Multiple recall statements in a production now produce an error. (#69)

  do {
    recall [foo: ?next ?]
    recall [foo: ? ?next]
  }
  

  This will result in:

  ERROR: only one recall statement per production is allowed in production 'start' (line 12)
  

• pyactr

  • Turn off subsymbolic on the model as it is not necessary for what we are doing at the moment. (#68)
  • Clear the retrieval buffer before trying to fill it with a recall statement. This forces the pyactr productions to work like the vanilla ACT-R ones. (#68)

Fixed

• all frameworks

  • Only output a description comment in the generated code if the description field is present in the amod file.

• pyactr

  • Generated code now handles printing of numbers and variables. (#65)

    It is still limited to one print per production (#66)

  • Fix addition2 example. (#39)
