Prompt Toolkit 2+ Shell (xonsh.ptk_shell.shell)

The prompt_toolkit based xonsh shell.

class xonsh.ptk_shell.shell.PromptToolkitShell(**kwargs)[source]

The xonsh shell for prompt_toolkit v2 and later.

cmdloop(intro=None)[source]

Enters a loop that reads and execute input from user.

color_style()[source]

Returns the current color map.

color_style_names()[source]

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)[source]

Displays dots in multiline prompt

default(line)

Implements code execution.

emptyline()

Called when an empty line has been entered.

format_color(string, hide=False, force_string=False, **kwargs)[source]

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.

precmd(line)

Called just before execution of line.

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

Prints a color string using prompt-toolkit color management.

prompt_tokens()[source]

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()[source]

An interface for resetting the TTY stdin mode. This is highly dependent on the shell backend. Also it is mostly optional since it only affects ^Z backgrounding behaviour.

rprompt_tokens()[source]

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)[source]

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: 'MULTI_COLUMN'>, 'none': None, 'readline': <CompleteStyle.READLINE_LIKE: 'READLINE_LIKE'>, 'single': <CompleteStyle.COLUMN: 'COLUMN'>}
property prompt

Obtains the current prompt string.

property styler
xonsh.ptk_shell.shell.remove_ansi_osc(prompt)[source]

Removes the ANSI OSC escape codes - prompt_toolkit does not support them. Some terminal emulators - like iTerm2 - uses them for various things.

See: https://www.iterm2.com/documentation-escape-codes.html

xonsh.ptk_shell.shell.tokenize_ansi(tokens)[source]

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.
