xonsh.shells.ptk_shell

The prompt_toolkit based xonsh shell.

class xonsh.shells.ptk_shell.PromptToolkitShell(**kwargs)

The xonsh shell for prompt_toolkit v2 and later.

Notes

classes inheriting multiple base classes should call them explicitly as done for ReadlineShell

cmdloop(intro=None)

Enters a loop that reads and execute input from user.

color_style()

Returns the current color map.

color_style_names()

Returns an iterable of all available style names.

compile(src)

Compiles source code and returns the (possibly modified) source and a valid code object.

continuation_tokens(width, line_number, is_soft_wrap=False)

Displays dots in multiline prompt

default(line, raw_line=None)

Implements code execution.

emptyline()

Called when an empty line has been entered.

format_color(string, hide=False, force_string=False, **kwargs)

Formats a color string using Pygments. This, therefore, returns a list of (Token, str) tuples. If force_string is set to true, though, this will return a color formatted string.

get_lazy_ptk_kwargs()

These are non-essential attributes for the PTK shell to start. Lazy loading these later would save some startup time.

get_prompt_style()

precmd(line)

Called just before execution of line.

print_color(string, end='\n', **kwargs)

Prints a color string using prompt-toolkit color management.

prompt_tokens()

Returns a list of (token, str) tuples for the current prompt.

push(line)

Pushes a line onto the buffer and compiles the code in a way that enables multiline input.

reset_buffer()

Resets the line buffer.

restore_tty_sanity()

An interface for resetting the TTY stdin mode. This is highly dependent on the shell backend. For prompt-toolkit it allows to fix case when terminal lost SIGINT catching and Ctrl+C is not working after abnormal exiting.

rprompt_tokens()

Returns a list of (token, str) tuples for the current right prompt.

settitle()

Sets terminal title.

singleline(auto_suggest=None, enable_history_search=True, multiline=True, **kwargs)

Reads a single line of input from the shell. The store_in_history kwarg flags whether the input should be stored in PTK’s in-memory history.

property bottom_toolbar_tokens

Returns self._bottom_toolbar_tokens if it would yield a result

completion_displays_to_styles = {'multi': CompleteStyle.MULTI_COLUMN, 'none': None, 'readline': CompleteStyle.READLINE_LIKE, 'single': CompleteStyle.COLUMN}

property prompt

Obtains the current prompt string.

property styler

xonsh.shells.ptk_shell.disable_copy_on_deletion()

xonsh.shells.ptk_shell.tokenize_ansi(tokens)

Checks a list of (token, str) tuples for ANSI escape sequences and extends the token list with the new formatted entries. During processing tokens are converted to prompt_toolkit.FormattedText. Returns a list of similar (token, str) tuples.

completer	Completer implementation to use with prompt_toolkit.
formatter	PTK specific PromptFormatter class.
history	History object for use with prompt_toolkit.
key_bindings	Key bindings for prompt_toolkit xonsh shell.
updator	Has classes that help updating Prompt sections using Threads.
