0.9.8 (February 06, 2019)

• Bug Fixes
  • Fixed issue with echoing strings in StdSim. Because they were being sent to a binary buffer, line buffering was being ignored.
• Enhancements
  • Made quit() and exit() functions available to scripts run with pyscript. This allows those scripts to exit back to the console's prompt instead of exiting the whole application.

0.9.7 (January 08, 2019)

• Bug Fixes
  • Fixed bug when user chooses a zero or negative index when calling Cmd.select()
  • Restored behavior where cmd_echo always starts as False in a py script. This was broken in 0.9.5.
• Enhancements
  • cmdloop now only attempts to register a custom signal handler for SIGINT if running in the main thread
  • commands run as a result of default_to_shell being True now run via do_shell() and are saved
    to history.
  • Added more tab completion to pyscript command.
• Deletions (potentially breaking changes)
  • Deleted Cmd.colorize() and Cmd._colorcodes which were deprecated in 0.9.5
  • Replaced dir_exe_only and dir_only flags in path_complete with optional path_filter function
    that is used to filter paths out of completion results.
  • perror() no longer prepends "ERROR: " to the error message being printed

0.9.6 (October 13, 2018)

• Bug Fixes
  • Fixed bug introduced in 0.9.5 caused by backing up and restoring self.prompt in pseudo_raw_input.
    As part of this fix, continuation prompts will not be redrawn with async_update_prompt or async_alert.
• Enhancements
  • All platforms now depend on wcwidth to assist with asynchronous alerts.
  • Macros now accept extra arguments when called. These will be tacked onto the resolved command.
  • All cmd2 commands run via py now go through onecmd_plus_hooks.

0.9.5 (October 11, 2018)

• Bug Fixes
  • Fixed bug where get_all_commands could return non-callable attributes
  • Fixed bug where alias command was dropping quotes around arguments
  • Fixed bug where running help on argparse commands didn't work if they didn't support -h
  • Fixed transcript testing bug where last command in transcript has no expected output
  • Fixed bugs with how AutoCompleter and ArgparseFunctor handle argparse
    arguments with nargs=argparse.REMAINDER. Tab completion now correctly
    matches how argparse will parse the values. Command strings generated by
    ArgparseFunctor should now be compliant with how argparse expects
    REMAINDER arguments to be ordered.
  • Fixed bugs with how AutoCompleter handles flag prefixes. It is no
    longer hard-coded to use '-' and will check against the prefix_chars in
    the argparse object. Also, single-character tokens that happen to be a
    prefix char are not treated as flags by argparse and AutoCompleter now
    matches that behavior.
  • Fixed bug where AutoCompleter was not distinguishing between a negative number and a flag
  • Fixed bug where AutoCompleter did not handle -- the same way argparse does (all args after -- are non-options)
• Enhancements
  • Added exit_code attribute of cmd2.Cmd class
    • Enables applications to return a non-zero exit code when exiting from cmdloop
  • ACHelpFormatter now inherits from argparse.RawTextHelpFormatter to make it easier
    for formatting help/description text
  • Aliases are now sorted alphabetically
  • The set command now tab-completes settable parameter names
  • Added async_alert, async_update_prompt, and set_window_title functions
    • These allow you to provide feedback to the user in an asychronous fashion, meaning alerts can
      display when the user is still entering text at the prompt. See async_printing.py
      for an example.
  • Cross-platform colored output support
    • colorama gets initialized properly in Cmd.__init()
    • The Cmd.colors setting is no longer platform dependent and now has three values:
      • Terminal (default) - output methods do not strip any ANSI escape sequences when output is a terminal, but
        if the output is a pipe or a file the escape sequences are stripped
      • Always - output methods never strip ANSI escape sequences, regardless of the output destination
      • Never - output methods strip all ANSI escape sequences
  • Added macro command to create macros, which are similar to aliases, but can take arguments when called
  • All cmd2 command functions have been converted to use argparse.
  • Renamed argparse_example.py to decorator_example.py to help clarify its intent
• Deprecations
  • Deprecated the built-in cmd2 support for colors including Cmd.colorize() and Cmd._colorcodes
• Deletions (potentially breaking changes)
  • The preparse, postparsing_precmd, and postparsing_postcmd methods deprecated in the previous release
    have been deleted
    • The new application lifecycle hook system allows for registration of callbacks to be called at various points
      in the lifecycle and is more powerful and flexible than the previous system
  • alias is now a command with sub-commands to create, list, and delete aliases. Therefore its syntax
    has changed. All current alias commands in startup scripts or transcripts will break with this release.
  • unalias was deleted since alias delete replaced it

0.9.4 (August 21, 2018)

• Bug Fixes
  • Fixed bug where preparse was not getting called
  • Fixed bug in parsing of multiline commands where matching quote is on another line
• Enhancements
  • Improved implementation of lifecycle hooks to support a plugin
    framework, see docs/hooks.rst for details.
  • New dependency on attrs third party module
  • Added matches_sorted member to support custom sorting of tab-completion matches
  • Added tab_autocomp_dynamic.py example
    • Demonstrates updating the argparse object during init instead of during class construction
• Deprecations
  • Deprecated the following hook methods, see hooks.rst for full details:
    • cmd2.Cmd.preparse() - equivalent functionality available
      via cmd2.Cmd.register_postparsing_hook()
    • cmd2.Cmd.postparsing_precmd() - equivalent functionality available
      via cmd2.Cmd.register_postparsing_hook()
    • cmd2.Cmd.postparsing_postcmd() - equivalent functionality available
      via cmd2.Cmd.register_postcmd_hook()

0.8.9 (August 20, 2018)

• Bug Fixes
  • Fixed extra slash that could print when tab completing users on Windows

NOTE: This is likely the final release of cmd2 for Python 2.7

0.9.3 (July 12, 2018)

• Bug Fixes
  • Fixed bug when StatementParser __init__() was called with terminators equal to None
  • Fixed bug when Cmd.onecmd() was called with a raw str
• Enhancements
  • Added --clear flag to history command that clears both the command and readline history.
• Deletions
  • The CmdResult helper class which was deprecated in the previous release has now been deleted
    • It has been replaced by the improved CommandResult class

0.9.2 (June 28, 2018)

• Bug Fixes
  • Fixed issue where piping and redirecting did not work correctly with paths that had spaces
• Enhancements
  • Added ability to print a header above tab-completion suggestions using completion_header member
  • Added pager and pager_chop attributes to the cmd2.Cmd class
    • pager defaults to less -RXF on POSIX and more on Windows
    • pager_chop defaults to less -SRXF on POSIX and more on Windows
  • Added chop argument to cmd2.Cmd.ppaged() method for displaying output using a pager
    • If chop is False, then self.pager is used as the pager
    • Otherwise self.pager_chop is used as the pager
  • Greatly improved the table_display.py example
    • Now uses the new tableformatter module which looks better than tabulate
• Deprecations
  • The CmdResult helper class is deprecated and replaced by the improved CommandResult class
    • CommandResult has the following attributes: stdout, stderr, and data
      • CmdResult had attributes of: out, err, war
    • CmdResult will be deleted in the next release

0.8.8 (June 28, 2018)

• Bug Fixes
  • Prevent crashes that could occur attempting to open a file in non-existent directory or with very long filename
• Enhancements
  • display_matches is no longer restricted to delimited strings
