v0.9.0 - 20 June 2022

Added

• gactar now handles installation of python packages, ACT-R code, and the Lisp compiler itself instead of using external scripts. (#212)

  There is a new command to run setup:

  $ ./gactar env setup
  

  Use the -dev flag to also install optional developer packages for linting & formatting Python code.

  $ ./gactar env setup -dev
  

• gactar's new setup capability should work on Windows with a couple of caveats:

  • It has only been tried with the 3.10.5 release from python.org on Windows 10.
  • gactar uses the PATH environment variable to find the Python interpreter. The easiest way to do this is to check the Add Python 3.10 to PATH checkbox when installing Python.
  • The Clozure Common Lisp compiler is currently broken on Windows (waiting on a new build). It will download, but will fail to run.

• Added a command to check the health of your virtual environment. (#220)

  $ ./gactar env doctor
  

  This will check paths, ensure that Python packages are installed properly, and check for the lisp compiler.

• Added an extra_buffers module to allow declaration of... extra buffers. (#217)

  Declare them in the module config section like this (they currently don't have any configuration options):

  modules {
      extra_buffers {
          foo {}
          bar {}
      }
  }
  

• Added partial_matching option to the procedural module to turn on partial matching. (#223)

  Note: while this can be turned on, specifying similarity of chunks isn't handled yet. (See #234)

• Added decay option to the declarative memory module for the base-level learning calculation. (#226)

Changed

• Allow ID in set statements. (#200)

  Instead of:

  set goal.state to 'harvest_location'
  

  You can use it without quotes:

  set goal.state to harvest_location
  

• Web assets are now compressed using brotli compression. (#218)

• Moved the default temp directory (gactar-temp) into the environment directory. (#229)

Fixed

• When not running setup, restrict the PATH environment variable to paths within the virtual environment directory. (#230)
