0.9.17 (September 23, 2019)

• Bug Fixes
  • Fixed a bug when using WSL when all Windows paths have been removed from $PATH
  • Fixed a bug when running a cmd2 application on Linux without Gtk libraries installed
• Enhancements
  • No longer treating empty text scripts as an error condition
  • Allow dynamically extending a cmd2.Cmd object instance with a do_xxx method at runtime
  • Choices/Completer functions can now be passed a dictionary that maps command-line tokens to their argparse argument. This is helpful when one argument determines what is tab completed for another argument. If these functions have an argument called arg_tokens, then AutoCompleter will automatically pass this dictionary to them.
  • Added CompletionError class that can be raised during argparse-based tab completion and printed to the user
  • Added the following convenience methods
    • Cmd.in_script() - return whether a text script is running
    • Cmd.in_pyscript() - return whether a pyscript is running
