2.4.1 (April 13, 2022)

• Bug Fixes
  • Fixed value for ansi.Bg.YELLOW.
  • Fixed unit tests for ansi.allow_style.
• Enhancements
  • async_alert() raises a RuntimeError if called from the main thread.

2.4.0 (February 22, 2022)

• Bug Fixes
  • Fixed issue in ansi.async_alert_str() which would raise IndexError if prompt was blank.
  • Fixed issue where tab completion was quoting argparse flags in some cases.
• Enhancements
  • Added broader exception handling when enabling clipboard functionality via pyperclip.
  • Added PassThroughException to __init__.py imports.
  • cmd2 now uses pyreadline3 when running any version of Python on Windows
  • Improved memory usage in certain use cases of tables (e.g. nested colored tables)
• Deletions (potentially breaking changes)
  • Deleted cmd2.fg and cmd2.bg which were deprecated in 2.3.0. Use cmd2.Fg and cmd2.Bg instead.

2.3.3 (November 29, 2021)

• Enhancements
  • Added clearer exception handling to BorderedTable and SimpleTable.

2.3.2 (November 22, 2021)

• Bug Fixes
  • Fixed issue where a ns_provider could be passed None instead of its correct cmd2.Cmd or CommandSet value.

2.3.1 (November 18, 2021)

• Bug Fixes
  • Fixed issue introduced in 2.3.0 with AlternatingTable, BorderedTable, and SimpleTable that caused
    header alignment settings to be overridden by data alignment settings.
• Enhancements
  • CompletionItems now saves the original object from which it creates a string.
  • Using CompletionItems as argparse choices is fully supported. cmd2 patched argparse to compare input to
    the original value instead of the CompletionItems instance.
  • ArgparseCompleter now does the following if a list of CompletionItems was created with numerical types:
    • Sorts completion hints numerically
    • Right-aligns the left-most column in completion hint table

2.3.0 (November 11, 2021)

• Bug Fixes
  • Fixed AttributeError in rl_get_prompt() when prompt is None.
  • Fixed bug where using choices on a Settable didn't verify that a valid choice had been entered.
  • Fixed bug introduced in cmd2 2.0.0 in which select() converts return values to strings. It should never
    have converted return values.
• Enhancements
  • Added settings to Column class which prevent a table from overriding existing styles in header
    and/or data text. This allows for things like nesting an AlternatingTable in another AlternatingTable.
  • AlternatingTable no longer automatically applies background color to borders. This was done to improve
    appearance since the background color extended beyond the borders of the table.
  • Added ability to colorize all aspects of AlternatingTables, BorderedTables, and SimpleTables.
  • Added support for 8-bit/256-colors with the cmd2.EightBitFg and cmd2.EightBitBg classes.
  • Added support for 24-bit/RGB colors with the cmd2.RgbFg and cmd2.RgbBg classes.
  • Removed dependency on colorama.
  • Changed type of ansi.allow_style from a string to an ansi.AllowStyle Enum class.
• Deprecations
  • Deprecated cmd2.fg. Use cmd2.Fg instead.
  • Deprecated cmd2.bg. Use cmd2.Bg instead.
• Breaking Changes
  • To support the color upgrade, all cmd2 colors now inherit from either ansi.FgColor or ansi.BgColor.
    Therefore, ansi.style() no longer accepts colors as strings.

2.2.0 (September 14, 2021)

• Bug Fixes
  • Fixed extra space appended to each alias by "alias list" command
• Enhancements
  • New function set_default_ap_completer_type() allows developer to extend and modify the
    behavior of ArgparseCompleter.
  • Added ArgumentParser.get_ap_completer_type() and ArgumentParser.set_ap_completer_type(). These
    methods allow developers to enable custom tab completion behavior for a given parser by using a custom
    ArgparseCompleter-based class.
  • Added ap_completer_type keyword arg to Cmd2ArgumentParser.__init__() which saves a call
    to set_ap_completer_type(). This keyword will also work with add_parser() when creating subcommands
    if the base command's parser is a Cmd2ArgumentParser.
  • New function register_argparse_argument_parameter() allows developers to specify custom
    parameters to be passed to the argparse parser's add_argument() method. These parameters will
    become accessible in the resulting argparse Action object when modifying ArgparseCompleter behavior.
  • Using SimpleTable in the output for the following commands to improve appearance.
    • help
    • set (command and tab completion of Settables)
    • alias tab completion
    • macro tab completion
  • Tab completion of CompletionItems now includes divider row comprised of Cmd.ruler character.
  • Removed --verbose flag from set command since descriptions always show now.
  • All cmd2 built-in commands now populate self.last_result.
  • Argparse tab completer will complete remaining flag names if there are no more positionals to complete.
  • Updated async_alert() to account for self.prompt not matching Readline's current prompt.
• Deletions (potentially breaking changes)
  • Deleted set_choices_provider() and set_completer() which were deprecated in 2.1.2
• Breaking Changes
  • Renamed set_default_argument_parser() to set_default_argument_parser_type()

2.1.2 (July 5, 2021)

• Enhancements
  • Added the following accessor methods for cmd2-specific attributes to the argparse.Action class
    • get_choices_callable()
    • set_choices_provider()
    • set_completer()
    • get_descriptive_header()
    • set_descriptive_header()
    • get_nargs_range()
    • set_nargs_range()
    • get_suppress_tab_hint()
    • set_suppress_tab_hint()
• Deprecations
  • Now that set_choices_provider() and set_completer() have been added as methods to the
    argparse.Action class, the standalone functions of the same name will be removed in version
    2.2.0. To update to the new convention, do the following:
    • Change set_choices_provider(action, provider) to action.set_choices_provider(provider)
    • Change set_completer(action, completer) to action.set_completer(completer)

2.1.1 (June 17, 2021)

• Bug Fixes
  • Fixed handling of argparse's default options group name which was changed in Python 3.10
• Enhancements
  • Restored plugins and tests_isolated directories to tarball published to PyPI for cmd2 release

2.1.0 (June 14, 2021)

• Enhancements
  • Converted persistent history files from pickle to compressed JSON
