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`.

-----------------
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.

- Bugfix in TabsProcessor: handle situations when the cursor is at the end of
the line.
2.0.1: 2018-06-02
-----------------
Version 2.0 includes a big refactoring of the internal architecture. This
includes the merge of the CommandLineInterface and the Application object, a
rewrite of how user controls are focused, a rewrite of how event loops work
and the removal of the buffers dictionary. This introduces many backwards
incompatible changes, but the result is a very nice and powerful architecture.
Most architectural changes effect full screen applications. For applications
that use `prompt_toolkit.shortcuts` for simple prompts, there are fewer
incompatibilities.
Changes:
- No automatic translation from \r into \n during the input processing. These
are two different keys that can be handled independently. This is a big
backward-incompatibility, because the `Enter` key is `ControlM`, not
`ControlJ`. So, now that we stopped translating \r into \n, it could be that
custom key bindings for `Enter` don't work anymore. Make sure to bind
`Keys.Enter` instead of `Keys.ControlJ` for handling the `Enter` key.
- The `CommandLineInterface` and the `Application` classes are merged. First,
`CommandLineInterface` contained all the I/O objects (like the input, output
and event loop), while the `Application` contained everything else. There was
no practical reason to keep this separation. (`CommandLineInterface` was
mostly a proxy to `Application`.)
A consequence is that almost all code which used to receive a
`CommandLineInterface`, will now use an `Application`. Usually, where we
had an attribute `cli`, we'll now have an attribute `app`.
Secondly, the `Application` object is no longer passed around. The `get_app`
function can be used at any time to acquire the active application.
(For backwards-compatibility, we have aliases to the old names, whenever
possible.)
- prompt_toolkit no longer depends on Pygments, but it can still use Pygments
for its color schemes and lexers. In many places we used Pygments "Tokens",
this has been replaced by the concept of class names, somewhat similar to
HTML and CSS.
* `PygmentsStyle` and `PygmentsLexer` adaptors are available for
plugging in Pygments styles and lexers.
* Wherever we had a list of `(Token, text)` tuples, we now have lists of
`(style_string, text)` tuples. The style string can contain both inline
styling as well as refer to a class from the style sheet. `PygmentsTokens`
is an adaptor that converts a list of Pygments tokens into a list of
`(style_string, text)` tuples.
- Changes in the `Style` classes.
* `style.from_dict` does not exist anymore. Instantiate the ``Style`` class
directory to create a new style. ``Style.from_dict`` can be used to create
a style from a dictionary, where the dictionary keys are a space separated
list of class names, and the values, style strings (like before).
* `print_tokens` was renamed to `print_formatted_text`.
* In many places in the layout, we accept a parameter named `style`. All the
styles from the layout hierarchy are combined to decide what style to be
used.
* The ANSI color names were confusing and inconsistent with common naming
conventions. This has been fixed, but aliases for the original names were
kept.
- The way focusing works is different. Before it was always a `Buffer` that
was focused, and because of that, any visible `BufferControl` that contained
this `Buffer` would be focused. Now, any user control can be focused. All
of this is handled in the `Application.layout` object.
- The `buffers` dictionary (`CommandLineInterface.buffers`) does not exist
anymore. Further, `buffers` was a `BufferMapping` that keeps track of which
buffer has the focus. This significantly reduces the freedom for creating
complex applications. We wanted to move toward a layout that can be defined
as a (hierarchical) collection of user widgets. A user widget does not need
to have a `Buffer` underneath and any widget should be focusable.
* `layout.Layout` was introduced to contain the root layout widget and keep
track of the focus.
- The key bindings were refactored. It became much more flexible to combine
sets of key bindings.
* `Registry` has been renamed to `KeyBindings`.
* The `add_binding` function has been renamed to simply `add`.
* Every `load_*` function returns one `KeyBindings` objects, instead of
populating an existing one, like before.
* `ConditionalKeyBindings` was added. This can be used to enable/disable
all the key bindings from a given `Registry`.
* A function named `merge_key_bindings` was added. This takes a list of
`KeyBindings` and merges them into one.
* `key_binding.defaults.load_key_bindings` was added to load all the key
bindings.
* `KeyBindingManager` has been removed completely.
* `input_processor` was renamed to `key_processor`.
Further:
* The `Key` class does not exist anymore. Every key is a string and it's
considered fine to use string literals in the key bindings. This is more
readable, but we still have run-time validation. The `Keys` enum still
exist (for backwards-compatibility, but also to have an overview of which
keys are supported.)
* 'enter' and 'tab' are key aliases for 'c-m' and 'c-i'.
- User controls can define key bindings, which are active when the user control
is focused.
* `UIControl` got a `get_key_bindings` (abstract) method.
- Changes in the layout engine:
* `LayoutDimension` was renamed to `Dimension`.
* `VSplit` and `HSplit` now take a `padding` argument.
* `VSplit` and `HSplit` now take an `align` argument.
(TOP/CENTER/BOTTOM/JUSTIFY) or (LEFT/CENTER/RIGHT/JUSTIFY).
* `Float` now takes `allow_cover_cursor` and `attach_to_window` arguments.
* `Window` got an `WindowAlign` argument. This can be used for the alignment
of the content. `TokenListControl` (renamed to `FormattedTextControl`) does
not have an alignment argument anymore.
* All container objects, like `Window`, got a `style` argument. The style for
parent containers propagate to child containers, but can be overriden.
This is in particular useful for setting a background color.
* `FillControl` does not exist anymore. Use the `style` and `char` arguments
of the `Window` class instead.
* `DummyControl` was added.
* The continuation function of `PromptMargin` now takes `line_number` and
`is_soft_wrap` as input.
- Changes to `BufferControl`:
* The `InputProcessor` class has been refactored. The `apply_transformation`
method should now takes a `TransformationInput` object as input.
* The text `(reverse-i-search)` is now displayed through a processor. (See
the `shortcuts` module for an example of its usage.)
- `widgets` and `dialogs` modules:
* A small collection of widgets was added. These are more complex collections
of user controls that are ready to embed in a layout. A `shortcuts.dialogs`
module was added as a high level API for displaying input, confirmation and
message dialogs.
* Every class that exposes a ``__pt_container__`` method (which is supposed
to return a ``Container`` instance) is considered a widget. The
``to_container`` shortcut will call this method in situations where a
``Container`` object is expected. This avoids inheritance from other
``Container`` types, but also having to unpack the container object from
the widget, in case we would have used composition.
* Warning: The API of the widgets module is not considered stable yet, and
can change is the future, if needed.
- Changes to `Buffer`:
* A `Buffer` no longer takes an `accept_action`. Both `AcceptAction` and
`AbortAction` have been removed. Instead it takes an `accept_handler`.
- Changes regarding auto completion:
* The left and right arrows now work in the multi-column auto completion
menu.
* By default, autocompletion is synchronous. The completer needs to be
wrapped in `ThreadedCompleter` in order to get asynchronous autocompletion.
* When the completer runs in a background thread, completions will be
displayed as soon as they are generated. This means that we don't have to
wait for all the completions to be generated, before displaying the first
one. The completion menus are updated as soon as new completions arrive.
- Changes regarding input validation:
* Added the `Validator.from_callable` class method for easy creation of
new validators.
- Changes regarding the `History` classes:
* The `History` base class has a different interface. This was needed for
asynchronous loading of the history. `ThreadedHistory` was added for this.
- Changes related to `shortcuts.prompt`:
* There is now a class `PromptSession` which also has a method `prompt`. Both
the class and the method take about the same arguments. This can be used to
create a session. Every `prompt` call of the same instance will reuse all
the arguments given to the class itself.
The input history is always shared during the entire session.
Of course, it's still possible to call the global `prompt` function. This
will create a new `PromptSession` every time when it's called.
* The `prompt` function now takes a `key_bindings` argument instead of
`key_bindings_registry`. This should only contain the additional bindings.
(The default bindings are always included.)
- Changes to the event loops:
* The event loop API is now closer to how asyncio works. A prompt_toolkit
`Application` now has a `Future` object. Calling the `.run_async()` method
creates and returns that `Future`. An event loop has a `run_until_complete`
method that takes a future and runs the event loop until the Future is set.
The idea is to be able to transition easily to asyncio when Python 2
support can be dropped in the future.
* `Application` still has a method `run()` that underneath still runs the
event loop until the `Future` is set and returns that result.
* The asyncio adaptors (like the asyncio event loop integration) now require
Python 3.5. (We use the async/await syntax internally.)
* The `Input` and `Output` classes have some changes. (Not really important.)
* `Application.run_sub_applications` has been removed. The alternative is to
call `run_coroutine_in_terminal` which returns a `Future`.
- Changes to the `filters` module:
* The `Application` is no longer passed around, so both `CLIFilter` and
`SimpleFilter` were merged into `Filter`. `to_cli_filter` and
`to_simple_filter` became `to_filter`.
* All filters have been turned into functions. For instance, `IsDone`
became `is_done` and `HasCompletions` became `has_completions`.
This was done because almost all classes were called without any arguments
in the `__init__` causing additional braces everywhere. This means that
`HasCompletions()` has to be replaced by `has_completions` (without
parenthesis).
The few filters that took arguments as input, became functions, but still
have to be called with the given arguments.
For new filters, it is recommended to use the `@Condition` decorator,
rather then inheriting from `Filter`.
- Other renames:
* `IncrementalSearchDirection` was renamed to `SearchDirection`.
* The `use_alternate_screen` parameter has been renamed to `full_screen`.
* `Buffer.initial_document` was renamed to `Buffer.document`.
* `TokenListControl` has been renamed to `FormattedTextControl`.
* `Application.set_return_value` has been renamed to `Application.set_result`.
- Other new features:
* `DummyAutoSuggest` and `DynamicAutoSuggest` were added.
* `DummyClipboard` and `DynamicClipboard` were added.
* `DummyCompleter` and `DynamicCompleter` were added.
* `DummyHistory` and `DynamicHistory` was added.
* `to_container` and `to_window` utilities were added.
1.0.9: 2016-11-07
-----------------
Fixes:
- Fixed a bug in the `cooked_mode` context manager. This caused a bug in
ptpython where executing `input()` would display ^M instead of accepting the
input.
- Handle race condition in eventloop/posix.py
- Updated ANSI color names for vt100. (High and low intensity colors were
swapped.)
New features:
- Added yank-nth-arg and yank-last-arg readline commands + Emacs bindings.
- Allow searching in Vi selection mode.
- Made text objects of the Vi 'n' and 'N' search bindings. This adds for
instance the following bindings: cn, cN, dn, dN, yn, yN
1.0.8: 2016-10-16
-----------------
Fixes:
- In 'shortcuts': complete_while_typing was a SimpleFilter, not a CLIFilter.
- Always reset color attributes after rendering.
- Handle bug in Windows when '$TERM' is not defined.
- Ignore errors when calling tcgetattr/tcsetattr.
(This handles the "Inappropriate ioctl for device" crash in some scenarios.)
- Fix for Windows. Correctly recognize all Chinese and Lithuanian characters.
New features:
- Added shift+left/up/down/right keys.
- Small performance optimization in the renderer.
- Small optimization in the posix event loop. Don't call time.time() if we
don't have an inputhook. (Less syscalls.)
- Turned the _max_postpone_until argument of call_from_executor into a float.
(As returned by `time.time`.) This will do less system calls. It's
backwards-incompatible, but this is still a private API, used only by pymux.)
- Added Shift-I/A commands in Vi block selection mode for inserting text at the
beginning of each line of the block.
- Refactoring of the 'selectors' module for the posix event loop. (Reuse the
same selector object in one loop, don't recreate it for each select.)
1.0.7: 2016-08-21
-----------------
Fixes:
- Bugfix in completion. When calculating the common completion to be inserted,
the new completions were calculated wrong.
- On Windows, avoid extra vertical scrolling if the cursor is already on screen.
New features:
- Support negative arguments for next/previous word ending/beginning.
1.0.6: 2016-08-15
-----------------
Fixes:
- Go to the start of the line in Vi navigation mode, when 'j' or 'k' have been
pressed to navigate to a new history entry.
- Don't crash when pasting text that contains \r\n characters. (This could
happen in iTerm2.)
- Python 2.6 compatibility fix.
- Allow pressing <esc> before each -ve argument.
- Better support for conversion from #ffffff values to ANSI colors in
Vt100_Output.
* Prefer colors with some saturation, instead of gray colors, if the given
color was not gray.
* Prefer a different foreground and background color if they were
originally not the same. (This avoids concealing text.)
New features:
- Improved ANSI color support.
* If the $PROMPT_TOOLKIT_ANSI_COLORS_ONLY environment variable has been
set, use the 16 ANSI colors only.
* Take an `ansi_colors_only` parameter in `Vt100_Output` and
`shortcuts.create_output`.
1.0.5: 2016-08-04
-----------------
Fixes:
- Critical fix for running on Windows. The gevent work-around in the inputhook
caused 'An operation was attempted on something that is not a socket'.
1.0.4: 2016-08-03
-----------------
Fixes:
- Key binding fixes:
* Improved handling of repeat arguments in Emacs mode. Pressing sequences
like 'esc---123' do now work (like GNU Readline):
- repetition of the minus sign is ignored.
- No esc prefix is required for each digit.
* Fix in ControlX-ControlX binding.
* Fix in bracketed paste.
* Pressing Control-U at the start of the line now deletes the newline.
* Pressing Control-K at the end of the line, deletes the newline after
the cursor.
* Support negative argument for Control-K
* Fixed cash when left/right were pressed with a negative argument. (In
Emacs mode.)
* Fix in ControlUp/ControlDown key bindings.
* Distinguish backspace from Control-H. They are not the same.
* Delete in front of the cursor when a negative argument has been given
to backspace.
* Handle arrow keys correctly in emacs-term.
- Performance optimizations:
* Performance optimization in Registry.
* Several performance optimization in filters.
* Import asyncio inline (only if required).
- Use the best possible selector in the event loop. This fixes bugs in
situations where we have too many open file descriptors.
- Fix UI freeze when gevent monkey patch has been applied.
- Fix segmentation fault in Alpine Linux. (Regarding the use of ioctl.)
- Use the correct colors on Windows. (When the foreground/background colors
have been modified.)
- Display a better error message when running in Idle.
- Additional flags for vt100 inputs: disable flow control.
- Also patch stderr in CommandLineInterface.patch_stdout_context.
New features:
- Allow users to enter Vi digraphs in reverse order.
- Improved autocompletion behaviour. See IPython issue #9658.
- Added a 'clear' function in the shortcuts module.
For future compatibility:
- `Keys.Enter` has been added. This is the key that should be bound for
handling the enter key.
Right now, prompt_toolkit translates \r into \n during the handling of the
input; this is not correct and makes it impossible to distinguish between
ControlJ and ControlM. Some applications bind ControlJ for custom handling of
the enter key, because this equals \n. However, in a future version we will
stop replacing \r by \n and at that point, the enter key will be ControlM.
So better is to use `Keys.Enter`, which becomes an alias for whatever the
enter key translates into.
1.0.3: 2016-06-20
-----------------
Fixes:
- Bugfix for Python2 in readline-like completion.
- Bugfix in readline-like completion visualisation.
New features:
- Added `erase_when_done` parameter to the `Application` class. (This was
required for the bug fixes.)
- Added (experimental) `CommandLineInterface.run_application_generator` method.
(Also required for the bug fix.)
1.0.2: 2016-06-16
-----------------
Fixes:
- Don't select the first completion when `complete_while_typing` is False.
(Restore the old behaviour.)
1.0.1: 2016-06-15
-----------------
Fixes:
- Bugfix in GrammarValidator and SentenceValidator.
- Don't leave the alternate screen on resize events.
- Use errors=surrogateescape, in order to handle mouse events in some
terminals.
- Ignore key presses in _InterfaceEventLoopCallbacks.feed_key when the CLI is in the done state.
- Bugfix in get_common_complete_suffix. Don't return any suffix when there are
completions that change whatever is before the cursor.
- Bugfix for Win32/Python2: use unicode literals: This crashed arrow navigation
on Windows.
- Bugfix in InputProcessor: handling of more complex key bindings.
- Fix: don't apply completions, if there is only one completion which doesn't
have any effect.
- Fix: correctly handle prompts starting with a newline in
prompt_toolkit.shortcuts.
- Fix: thread safety in autocomplete code.
- Improve styling for matching brackets. (Allow individual styling for the
bracket under the cursor and the other.)
- Fix in ShowLeadingWhiteSpaceProcessor/ShowTrailingWhiteSpaceProcessor: take
output encoding into account. (The signature had to change a little for
this.)
- Bug fix in key bindings: only activate Emacs system/open-in-editor bindings
if editing_mode is emacs.
- Added write_binary parameter to Vt100_Output. This fixes a bug in some cases
where we expect it to write non-encoded strings.
- Fix key bindings for Vi mode registers.
New features (**):
- Added shortcuts.confirm/create_confirm_application function.
- Emulate bracketed paste on Windows. (When the input stream contains multiple
key presses among which a newline and at least one other character, consider
this a paste event, and handle as bracketed paste on Unix.
- Added key handler for displaying completions, just like readline does.
- Implemented Vi guu,gUU,g~~ key bindings.
- Implemented Vi 'gJ' key binding.
- Implemented Vi ab,ib,aB,iB text objects.
- Support for ZeroWidthEscape tokens in prompt and token lists. Used to support
final shell integration.
- Fix: Make document.text/cursor_position/selection read-only. (Changing these
would break the caching causing bigger issues.)
- Using pytest for unit tests.
- Allow key bindings to have Keys.Any at any possible position. (Not just the
end.) This made it significantly easier to write the named register Vi
bindings, resulting in an approved start-up time.)
- Better feedback when entering multi-key key bindings in insert mode. (E.g.
when 'jj' would be mapped to escape.)
- Small improvement in key processor: allow key bindings to generate new key
presses.
- Handle ControlUp and ControlDown by default: move to the previous/next record
in the history.
- Accept 'char'/'get_char' parameters in FillControl.
- Added refresh_interval method to prompt() function.
Performance improvements:
- Improve the performance of test_callable_args: this should significantly
increase the start-up time.
- Start-up time for creating the Vi bindings has been improved significantly.
(**) Some small backwards-compatible features were allowed for this minor
release. After evaluating the impact/risk/work involved we concluded that
we could ship these in a minor release.
1.0.0: 2016-05-05
-----------------
Fixes:
- Adjust minimum completion menu width to match UIControl and Window class.
- Bugfix regarding weakref in InputProcessor.
- Fix for pypy3: bug in WeakValueDictionary.
- Correctly handle '0' key binding in Vi mode.
- Also load Vi bindings by default in Application if no registry has been given.
- Only go into selection mode if the current buffer is not empty.
- Close PipeInput after usage.
- Only use 16 colors in (Emacs) eterm-color.
- Bugfix in "xP Vi key binding.
- Bugfix in Vi { and } key binding.
- Fix: use correct token for Scrollbar in MultiColumnCompletionMenuControl.
- Handle negative values in translate_row_col_to_index.
- Handle decomposed unicode characters.
- Fixed Window.always_hide_cursor. (Parameter was ignored.)
- Fix in zz Vi key binding. (When render info is not available.)
- Fix in Document.get_cursor_up_position. (When an argument is given.)
New features:
- Separated `load_mouse_bindings`.
- Refactoring/simplification of the key bindings: better use of filters and
CLI.editing_mode.
- Added DummyOutput class and a few unit tests that test the whole CLI.
- Use the bisect module in Document._line_start_indexes instead of a custom
binary search. This should improve the performance.
- Stay in the same column when doing multiple up/down movements.
- Visual improvements:
* Implemented cursorcolumn, cursorline and colorcolumn.
* Only reserve menu space when `complete_while_typing=True` or when there are
completions to be displayed.
* Support for chaining tokens for combined styles. SelectedText will now
reverse the colors from the highlighting by default. Style
`Token.SelectedText` to set a fixed foreground/background.
Also for SearchMatch, we now use combined tokens.
* Support for dark gray on Windows.
* Default token for SystemToolbar and SearchToolbar.
* Display selection also on empty lines.
- Emacs key bindings improved:
* Recognize + handle ControlDelete key.
* Implemented meta-* and control-backslash key bindings.
- Vi key bindings improved:
* Handle inclusive and linewise motions properly.
* Fix g_ motion off by one character, and don't work when cursor is in
the trailing whitespace part of line.
* Make a(/a)/i(/i)/... motions. Find enclosing brackets instead of the next
bracket.
* Update N% motion according to vim behaviors.
* Fix | motion off by one character.
* ge/gE motions go to end of previous word, not start.
* Added Vi 'gm' key binding.
* Implemented 'gq' key binding in Vi mode. (Reshape text.)
* Vi operator/text object separation for key bindings.
* Added 'ap' (auto-paragraph) text object.
* Implemented Vi digraphs. ControlK will now insert a digraph.
* Implemented vi tilde_operator.
* Support named registers.
* Vi < and > key bindings became operators.
* Text objects and motions are now separate bindings.
* Improved copy/paste in Vi mode.
Backwards-incompatible changes:
- Don't reset the current buffer anymore by default in
CommandLineInterface.run(). Passing `reset_current_buffer=True` is now
required.
- Renamed MouseEventTypes to MouseEventType for consistency. The old name is
still valid, but deprecated.
- Refactoring of Callbacks. All events should now receive one argument, which
is the sender. (Further, Callback was renamed to Event.) This is mostly used
internally.
- Moved on_invalidate callback from CommandLineInterface to Application
- Renamed `PipeInput.send` to `PipeInput.send_text`. (Old deprecated name is
still kept as a valid alias.)
- Renamed SimpleLexer.default_token to SimpleLexer.token. (+
backwards-compatibility.)
- Refactoring of the filters: `ViStateFilter` has been deprecated. (Should not
be used anymore.) Use the filters, as defined in prompt_toolkit.filters.
- `editing_mode` is now a property of `CommandLineInterface`. This is replacing
the `vi_mode` parameter in `KeyBindingManager`.
- The default accept_action for the default Buffer in Application now becomes
IGNORE. This is a much more sensible default. Pass RETURN_DOCUMENT to get
the previous behaviour,
- Always expect an EventLoop instance in CommandLineInterface. Creating it in
__init__ caused a memory leak.
0.60: 2016-03-14
----------------
Fixes:
- Fix in Document.paste. (The screen was not updated after an undo of a paste.)
- Don't use deprecated inspect.getargspec on Python 3.
- Fixed reading input on Windows when input was piped in stdin.
- Use correct file descriptors for input/output in run_system_command.
- Always correctly split prompt in shortcuts.prompt. (Even when multiline=False)
- Correctly align right prompt to the top when the left prompt consists of
multiple lines.
- Correctly use Token.Transparent as default token for a TokenListControl.
- Fix in syntax synchronisation. (Better handle the case when no
synchronisation point was found.)
- Send SIGTSTP to the whole process group.
- Correctly raise on_buffer_changed on all text changes.
- Fix in regular_languages.GrammarLexer. (Fixes bug in ptipython syntax
highlighting.)
New features:
- Add support for additional readers to the Win32 event loop.
- Added on_render event.
- Carry the weight in layout dimensions to allow stretching.
0.59: 2016-02-27
----------------
Fixes:
- Set correct default color on Windows. (Gray instead of high intensity gray.)
- Reverse colors on Windows when foreground/background color have not been
specified.
- Correct handling of mouse events for FillControl.
- Take margin into account when calculating Window height. (Fixes bug in
multiline prompt.)
- Handle division by zero in UIContent.get_height_for_text.
0.58: 2016-02-23
----------------
Fixes:
- Correctly return result for mouse handler in TokenListControl.
- Bugfix in meta-backspace key binding. (Delete all whitespace before the
cursor, when there is only whitespace.)
- Bugfix in Vi gu, gU, g? and g~ key bindings (in selection mode).
- Correctly restore default console attributes on Windows.
- Disable bracketed paste support in ConEmu. (This was broken.)
- When an unknown exception is raised in `CommandLineInterface.run()`, don't
forget to redraw the CLI.
New features:
- Many performance improvements and better caching. (Especially in the
`Document` class.)
- Support for continuation tokens in `shortcuts.prompt` and
`shortcuts.create_prompt_layout`.
- Added `shortcuts.print_tokens` function for printing colored output.
- Sound bell when nothing was deleted.
- Added escape sequences for F1-F5 keys on the Linux console.
- Improved support for the Linux console. (Switch back to 16 colors.)
- Added F13-F24 input codes for xterm.
- Created prompt_toolkit.token. A custom Token implementation, that is
compatible with Pygments.token. (This way, Pygments becomes an optional
dependency. For many use cases, nothing except the Token class from Pygments
was used, so it was a bit overkill to install Pygments for only that.)
- Refactoring of prompt_toolkit.styles.
- `Float` objects got a `hide_when_covering_content` option.
- Implementation of RPROMPT, like ZSH: Added `get_rprompt_tokens` to
`create_prompt_layout`.
- Some improvements to the default style.
- Also handle Ctrl-R and Ctrl-S in Vi mode when searching.
- Added TabsProcessor: a tool to visualise tabs instead of displaying ^I.
- Give a better error message when trying to run in git-bash.
- Support for ANSI color names in style dictionaries.
- Big refactoring of the `Window` and `UIControl` classes. This should result
in huge performance improvements on big inputs. (While first, a document
could have 1,000 lines; now it can have about 100,000 lines on the same system.)
The Window and UIControl have been rewritten very much. Rather than each time
rendering the whole user control, we now only have to render the visible part.
Because of this, many pieces had to be rewritten:
- UIControls work differently. They return a `UIContent` instance that
consist of a collection of lines.
- All processors have been rewritten. (Their API changed as well, because
they process one line at a time.)
- Lexers work differently. `Lexer.lex_document` should now return a function
that returns the tokens for one line. PygmentsLexer has been optimized that
it becomes 'lazy', and it has optional syntax synchronisation. That means,
that the lexer doesn't have to start the lexing at the beginning of the
document. (Which would be slow for big documents.)
Backwards-incompatible changes:
- As mentioned above, the refactoring of `Window` and `UIControl` caused many
"internal" APIs to change. All custom `UIControl`, `Processor` and `Lexer`
classes have to be rewritten. However, for most applications this should not
be an issue. Especially, the `shortcuts.prompt` function is
backwards-compatible.
- `wrap_lines` became a property of `Window` instead of `BufferControl`.
0.57: 2016-01-04
----------------
Fixes:
- Made `max_render_postpone_time` configurable. The current default was bad.
(We should probably always draw the UI once every cycle of the event loop.)
0.56: 2016-01-03
----------------
Fixes:
- Fix in bracketed paste. It was not correctly enabled for each prompt.
0.55: 2016-01-03
----------------
New features:
- Implemented bracketed paste mode. (This allows much faster pasting, as well
as pasting without going into paste mode. This makes sure that indentation in
ptpython for instance is kept correctly.)
- Added support for italic output and blink. (For terminals that support it.)
- Added get_horizontal_scroll, get_vertical_scroll and always_hide_cursor
parameters to Window.
- Refactoring of the posix event loop. Better scheduling of all tasks/FDs to
avoid starvation. (Everything should feel more responsive in high CPU
situations.)
- Added get_default_char function to TokenListControl.
- AppendAutoSuggestion now accepts a token parameter.
- Support for ansi color names in styles.
- Accept get_width/get_height parameters in Float.
- Added Output.write_raw and accept 'raw' parameter in
CommandLineInterface.stdout_proxy.
- Better caching of tokens in TokenListControl.
- Add mouse support to TokenListControl.
- Display "Window too small" when the window becomes too small.
- Added 'bell' function to Output.
- Accept weights in HSplit/VSplit.
- Added Registry.remove_binding method to dynamically remove key bindings.
- Added focus_on_click parameter to BufferControl.
- Introduced BufferMapping class as a wrapper around the buffers dictionary.
This one also contains the focus stack.
- Improved 'v' and 'V' key bindings. Allow switching between line and character
selection modes.
- Added layout.highlighters. A new, much faster way to do selection and search
highlighting.
- Make search_state dynamic for key bindings.
- Added 'sentence' option to WordCompleter.
- Cache Document.lines for better performance.
- Implementation of BLOCK selections. (Cut, copy, paste.)
- Accept a 'reserve_space_for_menu' parameter in the shortcuts. (This is an
integer.)
- Support for 24bit true color on vt100 terminals.
- Added CommandLineInterface.on_invalidate event.
- Added __version__ to __init__.py.
Fixes:
- Always show cursor in the 'done' state.
- Allow HSplit to have zero children.
- Bugfix for handling of backslash on Windows with some non-us keyboards.
(Ptpython issue #28.)
- Never render characters outside the visible screen region.
- Fix in WordCompleter. When case insensitive and input contained uppercase.
- Highlight search match when the cursor is at any position on the match. (not
just the beginning.)
Backwards-incompatible changes:
(Most changes will probably not have an impact on external applications.)
- Change in the `Style` API. This allows caching of Attrs in renderer and
faster rendering. (Style now has a get_attrs_for_token instead of a
get_token_to_attributes_dict method.)
- Removed DefaultStyle. Created PygmentsStyle.from_defaults class method instead.
- Removed AbortAction.IGNORE. This was ambiguous.
- Accept 'cli' parameter in 'walk' and 'find_window_for_buffer_name'.
- The focus stack is now stored in BufferMapping.
- ViStateFilter and KeyBindingManager now accept a get_vi_state callable
instead of vi_state itself. (This way a key bindings registry becomes
stateless.)
- HighlightSearchProcessor and HighlightSelectionProcessor became deprecated.
(Use highlighters instead.)
0.54: 2015-10-29
----------------
New features:
- Allow CommandLineInterface to run in any thread.

Fixes:
- Fix in auto suggestion: hide suggestion when accepting input.
0.51: 2015-09-24
----------------

scrolling and clicking.
- Added auto suggestions. (Like the fish shell.)
- Stdout proxy become thread safe.
- Linewrapping can now be disabled, instead we get horizontal scrolling.
- Line numbering can now be relative. Like the vi 'relativenumber' option.
Fixes:
- Fixed excessive scrolling in Windows.
- Bugfix in search highlighting.
- Copy all words during repetition of Ctrl-W presses.
- The 'libs' folder has been removed.
- Fix in MultiColumnCompletionsMenu: don't create very big columns.
Backwards-incompatible changes:
- Disable search by default in KeyBindingManager.
- Separated abort/exit key bindings. Disabled by default in KeyBindingManager.
- 'Ignore' became the default on_abort action in `Application`.
- 'Ignore' became the default accept_action in `Buffer`.
- The layout processors have been refactored. The API is changed.
- `SwitchableValidator` has been renamed to `ConditionalValidator`.
- `WindowRenderInfo` has several incompatible changes.
- Margins have been refactored completely. Now it's the window that has the
margin instead of `BufferControl`. Is is both much more performant and
flexible.
0.50: 2015-09-06
----------------
Fix:
- Leaving of alternate screen on Windows.
0.49: 2015-09-06

- Added support for sub CommandLineInterfaces.
- Accept optional vi_state parameter in KeyBindingManager.
Fixes:

the cursor.
- Fix in Control-W key binding. When there is only whitespace before the
cursor, delete the whitespace.
- Rendering bug fix in open_in_editor: run editor using cli.run_in_terminal.
- Fix in renderer. Correctly reserve the vertical space as required by the
layout.
- Small fix in Margin ABC.
- Added __iter__ to History ABC.
- Small bugfix in CommandLineInterface: create correct eventloop when no

New features:
- Added `prompt_toolkit.layout.utils.iter_token_lines`.
- Allow `None` values on the focus stack.

Fixes:
- Don't trigger autocompletion on paste.
- Added `pre_run` parameter to CommandLineInterface.
- Correct invalidation of BeforeInput and AfterInput.
- Correctly handle transparency. (For floats.)
- Small change in the algorithm to determine Window dimensions: keep in the
bounds of the Window dimensions.
Backwards-incompatible changes:
- There a now a `Lexer` abstract base class. Every lexer should be an instance
of that class, and Pygments lexers should be wrapped in a `PygmentsLexer`
class. `prompt_toolkit.shortcuts` still accepts Pygments lexers directly for
backwards-compatibility.
- BufferControl no longer has a `show_line_numbers` argument. Pass a
`NumberedMargin` instance instead.
- The `History` class became an abstract base class and only defines an
interface. The default history class is now called `InMemoryHistory`.
0.46: 2015-08-08
----------------
New features:
- By default, in shortcuts, only show search highlighting when the search is
the current input buffer.
- Accept 'count' for all search operations. (For repetition.)

- Python 2.6 compatibility fix.
- Show cursor at the correct position during reverse-i-search.
- Fixed stdout encoding bug for vt100 output.
Backwards-incompatible changes:
- Use of `ConditionalContainer` everywhere. The `Window` class no longer
accepts a `filter` argument to decide about the visibility. Instead
wrapping inside a `ConditionalContainer` class is required.
0.45: 2015-07-30
----------------
Fixes:
- Bug fix on OS X: correctly detect platform as not Windows.
