[dependabot]

Bumps prompt-toolkit from 3.0.26 to 3.0.29.

Changelog

Sourced from prompt-toolkit's changelog.

3.0.29: 2022-04-04

New features:

• Accept 'handle_sigint' parameter in PromptSession.

Fixes

• Fix 'variable referenced before assignment' error in vt100 mouse bindings.
• Pass handle_sigint from Application.run to Application.run_async.
• Fix detection of telnet client side changes.
• Fix print_container utility (handle EOFError).

Breaking changes:

• The following are now context managers: create_pipe_input, PosixPipeInput and Win32PipeInput.

3.0.28: 2022-02-11

New features:

• Support format specifiers for HTML and ANSI formatted text.
• Accept defaults for checkbox and radio list, and their corresponding dialogs.

Fixes:

• Fix resetting of cursor shape after the application terminates.

3.0.27: 2022-02-07

New features:

• Support for cursor shapes. The cursor shape for prompts/applications can now be configured, either as a fixed cursor shape, or in case of Vi input mode, according to the current input mode.
• Handle "cursor forward" command in ANSI formatted text. This makes it possible to render many kinds of generated ANSI art.
• Accept align attribute in Label widget.
• Added PlainTextOutput: an output implementation that doesn't render any ANSI escape sequences. This will be used by default when redirecting stdout to a file.
• Added create_app_session_from_tty: a context manager that enforces input/output to go to the current TTY, even if stdin/stdout are attached to pipes.
• Added to_plain_text utility for converting formatted text into plain text.

Fixes:

• Don't automatically use sys.stderr for output when sys.stdout is not a TTY, but sys.stderr is. The previous behavior was confusing, especially when rendering formatted text to the output, and we expect it to follow
