xonsh.shells.dumb_shell

A dumb shell for when $TERM == ‘dumb’, which usually happens in emacs.

class xonsh.shells.dumb_shell.DumbShell(*args, **kwargs)

A dumb shell for when $TERM == ‘dumb’, which usually happens in emacs.

Notes

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

cmdloop(intro=None)

Repeatedly issue a prompt, accept input, parse an initial prefix off the received input, and dispatch to action methods, passing them the remainder of the line as argument.

color_style()

Returns the current color map.

color_style_names()

Returns an iterable of all available style names.

columnize(list, displaywidth=80)

Display a list of strings as a compact set of columns.

Each column is only as wide as necessary. Columns are separated by two spaces (one was not legible enough).

compile(src)

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

complete(text, state)

Return the next possible completion for ‘text’.

If a command has not been entered, then complete against command list. Otherwise try to call complete_<command> to get list of completions.

complete_help(*args)

completedefault(prefix, line, begidx, endidx)

Implements tab-completion for text.

completenames(prefix, line, begidx, endidx)

Implements tab-completion for text.

default(line, raw_line=None)

Implements code execution.

do_help(arg)

List available commands with “help” or detailed help with “help cmd”.

emptyline()

Called when an empty line has been entered.

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

Readline implementation of color formatting. This uses ANSI color codes.

get_names()

onecmd(line)

Interpret the argument as though it had been typed in response to the prompt.

This may be overridden, but should not normally need to be; see the precmd() and postcmd() methods for useful execution hooks. The return value is a flag indicating whether interpretation of commands by the interpreter should stop.

parseline(line)

Overridden to no-op.

postcmd(stop, line)

Called just before execution of line. For readline, this handles the automatic indentation of code blocks.

postloop()

Hook method executed once when the cmdloop() method is about to return.

precmd(line)

Called just before execution of line.

preloop()

Hook method executed once when the cmdloop() method is called.

print_color(string, hide=False, **kwargs)

Prints a string in color. This base implementation’s colors are based on ANSI color codes if a string was given as input. If a list of token pairs is given, it will color based on pygments, if available. If pygments is not available, it will print a colorless string.

print_topics(header, cmds, cmdlen, maxcol)

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. Also it is mostly optional since it only affects ^Z backgrounding behaviour.

settitle()

Sets terminal title.

singleline(store_in_history=True, **kwargs)

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

doc_header = 'Documented commands (type help <topic>):'

doc_leader = ''

identchars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_'

intro = None

lastcmd = ''

misc_header = 'Miscellaneous help topics:'

nohelp = '*** No help on %s'

property prompt

Obtains the current prompt string.

ruler = '='

property styler

undoc_header = 'Undocumented commands:'
