Cmd2

* Bug Fixes
* Added workaround for bug which occurs in Python 2.7 on Linux when ``pygtk`` is installed
* ``pfeedback()`` now honors feedback_to_output setting and won't redirect when it is ``False``
* For ``edit`` command, both **editor** and **filename** can now have spaces in the name/path
* Fixed a bug which occurred when stdin was a pipe instead of a tty due to input redirection
* Enhancements
* ``feedback_to_output`` now defaults to ``False`` so info like command timing won't redirect
* Transcript regular expressions now have predictable, tested, and documented behavior
* This makes a breaking change to the format and expectations of transcript testing
* The prior behavior removed whitespace before making the comparison, now whitespace must match exactly
* Prior version did not allow regexes with whitespace, new version allows any regex
* Improved display for ``load`` command and input redirection when **echo** is ``True``

* Bug Fixes
* Case-sensitive command parsing was completely broken and has been fixed
* ``<Ctrl>+d`` now properly quits when case-sensitive command parsing is enabled
* Fixed some pyperclip clipboard interaction bugs on Linux
* Fixed some timing bugs when running unit tests in parallel by using monkeypatch
* Enhancements
* Enhanced tab completion of cmd2 command names to support case-insensitive completion
* Added an example showing how to remove unused commands
* Improved how transcript testing handles prompts with ANSI escape codes by stripping them
* Greatly improved implementation for how command output gets piped to a shell command

* Bug Fixes
* `case_insensitive` is no longer a runtime-settable parameter, but it was still listed as such
* Fixed a recursive loop bug when abbreviated commands are enabled and it could get stuck in the editor forever
* Added additional command abbreviations to the "exclude from history" list
* Fixed argparse_example.py and pirate.py examples and transcript_regex.txt transcript
* Fixed a bug in a unit test which occurred under unusual circumstances
* Enhancements
* Organized all attributes used to configure the ParserManager into a single location
* Set the default value of `abbrev` to `False` (which controls whether or not abbreviated commands are allowed)
* With good tab completion of command names, using abbreviated commands isn't particularly useful
* And it can create complications if you are't careful
* Improved implementation of `load` to use command queue instead of nested inner loop

* Bug fixes
* Fixed a couple bugs in interacting with pastebuffer/clipboard on macOS and Linux
* Fixed a couple bugs in edit and save commands if called when history is empty
* Ability to pipe ``cmd2`` command output to a shell command is now more reliable, particularly on Windows
* Fixed a bug in ``pyscript`` command on Windows related to ``\`` being interpreted as an escape
* Enhancements
* Ensure that path and shell command tab completion results are alphabetically sorted
* Removed feature for load command to load scripts from URLS
* It didn't work, there were no unit tests, and it felt out of place
* Removed presence of a default file name and default file extension
* These also strongly felt out of place
* ``load`` and ``_relative_load`` now require a file path
* ``edit`` and ``save`` now use a temporary file if a file path isn't provided
* ``load`` command has better error checking and reporting
* Clipboard copy and paste functionality is now handled by the **pyperclip** module
* ``shell`` command now supports redirection and piping of output
* Added a lot of unit tests
* Other changes
* Removed pause command
* Added a dependency on the **pyperclip** module

* Bug fixes
* Fixed a bug in displaying a span of history items when only an end index is supplied
* Fixed a bug which caused transcript test failures to display twice
* Enhancements
* Added the ability to exclude commands from the help menu (**eof** included by default)
* Redundant **list** command removed and features merged into **history** command
* Added **pyscript** command which supports tab completion and running Python scripts with arguments
* Improved tab completion of file system paths, command names, and shell commands
* Thanks to Kevin Van Brunt for all of the help with debugging and testing this
* Changed default value of USE_ARG_LIST to True - this affects the beavhior of all **options** commands
* **WARNING**: This breaks backwards compatibility, to restore backwards compatibility, add this to the
**__init__()** method in your custom class derived from cmd2.Cmd:
* cmd2.set_use_arg_list(False)
* This change improves argument parsing for all new applications
* Refactored code to encapsulate most of the pyparsing logic into a ParserManager class

* Added a MANIFEST.ini file to make sure a few extra files get included in the PyPI source distribution
