0.9.12 (April 22, 2019) 🌍

• Bug Fixes
  • Fixed a bug in how redirection and piping worked inside py or pyscript commands
  • Fixed bug in async_alert where it didn't account for prompts that contained newline characters
  • Fixed path completion case when CWD is just a slash. Relative path matches were incorrectly prepended with a slash.
• Enhancements
  • Added ability to include command name placeholders in the message printed when trying to run a disabled command.
    • See docstring for disable_command() or disable_category() for more details.
  • Added instance attributes to customize error messages without having to override methods. Theses messages can also be colored.
    • help_error - the error that prints when no help information can be found
    • default_error - the error that prints when a non-existent command is run
  • The with_argparser decorators now add the Statement object created when parsing the command line to the argparse.Namespace object they pass to the do_* methods. It is stored in an attribute called __statement__. This can be useful if a command function needs to know the command line for things like logging.
  • Added a -t option to the load command for automatically generating a transcript based on a script file
  • When in a pyscript, the stdout and stderr streams of shell commands and processes being piped to are now captured and included in the CommandResult structure.
• Potentially breaking changes
  • The following commands now write to stderr instead of stdout when printing an error. This will make catching errors easier in pyscript.
    • do_help() - when no help information can be found
    • default() - in all cases since this is called when an invalid command name is run
    • _report_disabled_command_usage() - in all cases since this is called when a disabled command is run
  • Removed *** from beginning of error messages printed by do_help() and default()
  • Significantly refactored cmd.Cmd class so that all class attributes got converted to instance attributes, also:
    • Added allow_redirection, terminators, multiline_commands, and shortcuts as optional arguments to cmd2.Cmd.__init__()
    • A few instance attributes were moved inside StatementParser and properties were created for accessing them
  • self.pipe_proc is now called self.cur_pipe_proc_reader and is a ProcReader class.
  • Shell commands and commands being piped to while in a pyscript will function as if their output is going to a pipe and not a tty. This was necessary to be able to capture their output.
  • Removed reserved_words class attribute due to lack of use
  • Removed keywords instance attribute due to lack of use
