Introduction of the Export feature

This release introduce an experimental export feature that allows users to export modelx models as self-contained Python packages. The feature is available as an API function or a method on the Model class:

• export_model()

• Model.export

They both function the same.

An option to report local variables in error trace

get_traceback() now has an option show_locals, to indicate whether the tracebacks should report the values of local variables. It is set to False by default.

Bug Fixes

• Fix error when writing multiple models with the same files (GH81)

• Retries writing to a zip archive on a network location (GH82)

• Fix error with OpenPyXL 3.1+

• Fix error in trace_locals

Changes

• The following methods are now deprecated and they simply call their corresponding construction methods and assign input values from the files. They no longer carry the metadata of their input files to store the data in separate files.

  • Model.new_space_from_excel

  • Model.new_space_from_csv

  • Model.new_space_from_pandas

  • UserSpace.new_space_from_excel

  • UserSpace.new_space_from_csv

  • UserSpace.new_space_from_pandas

  • UserSpace.new_cells_from_excel

  • UserSpace.new_cells_from_csv

  • UserSpace.new_cells_from_pandas

• get_traceback() now reports local variables only when show_locals is True.

• modelx now depends on LibCST.
