Log Message:
py-prompt_toolkit2: added version 2.0.7

2.0.7:
Bug fixes:
- Fixed assertion in PromptSession: the style_transformation check was wrong.
- Removed 'default' attribute in PromptSession. Only ask for it in the
  prompt() method. This fixes the issue that passing default once, will
  store it for all consequent calls in the PromptSession.
- Ensure that __pt_formatted_text__ always returns a FormattedText
  instance. This fixes an issue with print_formatted_text.

New features:
- Improved handling of situations where stdin or stdout are not a terminal.
  (Print warning instead of failing with an assertion.)
- Added print_container utility.
- Sound bell when attempting to edit read-only buffer.
- Handle page-down and page-up keys in RadioList.
- Accept any collections.abc.Sequence for HSplit/VSplit children (instead of
  lists only).
- Improved Vi key bindings: return to navigation mode when Insert is pressed.

2.0.6:
Bug fixes:
- Don't use the predefined ANSI colors for colors that are defined as RGB.
  (Terminals can assign different color schemes for ansi colors, and we don't
  want use any of those for colors that are defined like #aabbcc for instance.)
- Fix in handling of CPRs when patch_stdout is used.

Backwards incompatible changes:
- Change to the Buffer class. Reset the buffer unless the accept_handler
  returns True (which means: "keep_text"). This doesn't affect applications
  that use PromptSession.

New features:
- Added AdjustBrightnessStyleTransformation. This is a simple style
  transformation that improves the rendering on terminals with light or dark
  background.
- Improved performance (string width caching and line height calculation).
- Improved TextArea:
  * Exposed focus_on_click.
  * Added attributes: auto_suggest, complete_while_typing, history,
    get_line_prefix, input_processors.
  * Made attributes writable: lexer, completer, complete_while_typing,
    accept_handler, read_only, wrap_lines.

2.0.5:
Bug fixes:
- Fix in DynamicContainer. Return correct result for get_children. This
  fixes a bug related to focusing.
- Properly compute length of start, end and sym_b characters of
  progress bar.
- CPR (cursor position request) fix.

Backwards incompatible changes:
- Stop restoring PromptSession attributes when exiting prompt.

New features:
- Added get_line_prefix attribute to window. This opens many
  possibilities:
  * Line wrapping (soft and hard) can insert whitespace in front
    of the line, or insert some symbols in front. Like the Vim \ 
"breakindent"
    option.
  * Single line prompts also support line continuations now.
  * Line continuations can have a variable width.
- For VI mode: implemented temporary normal mode (control-O in insert mode).
- Added style transformations API. Useful for swapping between light and
  dark color schemes. Added swap_light_and_dark_colors parameter to
  prompt() function.
- Added format() method to ANSI formatted text.
- Set cursor position for Button widgets.
- Added pre_run argument to PromptSession.prompt() method.

2.0.4:
Bug fixes:
- Fix render height for rendering full screen applications in Windows.
- Fix in TextArea. Set accept_handler to None if not given.
- Go to the beginning of the next line when enter is pressed in Vi navigation
  mode, and the buffer doesn't have an accept handler.
- Fix the default argument of the prompt function when called multiple
  times.
- Display decomposed multiwidth characters correctly.
- Accept history in prompt() function again.

Backwards incompatible changes:
- Renamed PipeInput to PosixPipeInput. Added Win32PipeInput and
  create_input_pipe.
- Pass buffer argument to the accept_handler of TextArea.

New features:
- Added accept_default argument to prompt().
- Make it easier to change the body/title of a Frame/Dialog.
- Added DynamicContainer.
- Added merge_completers for merging multiple completers together.
- Add vt100 data to key presses in Windows.
- Handle left/right key bindings in Vi block insert mode.

2.0.3:
Bug fixes:
- Fix in 'x' and 'X' Vi key bindings. Correctly handle line endings and args.
- Fixed off by one error in Vi line selection.
- Fixed bugs in Vi block selection. Correctly handle lines that the selection
  doesn't cross.
- Python 2 bugfix. Handle str/unicode correctly.
- Handle option+left/right in iTerm.

2.0.2:
Bug fixes:
- Python 3.7 support: correctly handle StopIteration in asynchronous generator.
- Fixed off-by-one bug in Vi visual block mode.
- Bugfix in TabsProcessor: handle situations when the cursor is at the end of
  the line.
