0.9.14
6d27e07
  • Enhancements
    • Added support for and testing with Python 3.8, starting with 3.8 beta
    • Improved information displayed during transcript testing
    • Added ansi module with functions and constants to support ANSI escape sequences which are used for things like applying style to text
    • Added support for applying styles (color, bold, underline) to text via style() function in ansi module
    • Added default styles to ansi.py for printing success, warning. and error text. These are the styles used by cmd2 and can be overridden to match the color scheme of your application.
    • Added ansi_aware_write() function to ansi module. This function takes into account the value of allow_ansi to determine if ANSI escape sequences should be stripped when not writing to a tty. See documentation for more information on the allow_ansi setting.
  • Breaking Changes
    • Python 3.4 reached its end of life on March 18, 2019 and is no longer supported by cmd2
      • If you need to use Python 3.4, you should pin your requirements to use cmd2 0.9.13
    • Made lots of changes to minimize the public API of the cmd2.Cmd class
      • Attributes and methods we do not intend to be public now all begin with an underscore
      • We make no API stability guarantees about these internal functions
    • Split perror into 2 functions:
      • perror - print a message to sys.stderr
      • pexcept - print Exception message to sys.stderr. If debug is true, print exception traceback if one exists
    • Signature of poutput and perror significantly changed
      • Removed color parameters color, err_color, and war_color from poutput and perror
        • See the docstrings of these methods or the cmd2 docs for more info on applying styles to output messages
      • end argument is now keyword-only and cannot be specified positionally
      • traceback_war no longer exists as an argument since it isn't needed now that perror and pexcept exist
    • Moved cmd2.Cmd.colors to ansi.py and renamed it to allow_ansi. This is now an application-wide setting.
    • Renamed the following constants and moved them to ansi.py
      • COLORS_ALWAYS --> ANSI_ALWAYS
      • COLORS_NEVER --> ANSI_NEVER
      • COLORS_TERMINAL --> ANSI_TERMINAL
  • Renamed Commands Notice
    • The following commands have been renamed. The old names will be supported until the next release.
      • load --> run_script
      • _relative_load --> _relative_run_script
      • pyscript --> run_pyscript
