Module: terminal.magics

Extra magics for terminal use.

1 Class

class IPython.terminal.magics.TerminalMagics(**kwargs: Any)

Bases: Magics

__init__(shell)

Create a configurable given a config config.

Parameters:

  • config (Config) – If this is empty, default values are used. If config is a Config instance, it will be used to configure the instance.

  • parent (Configurable instance, optional) – The parent Configurable instance of this object.

Notes

Subclasses of Configurable must call the __init__() method of Configurable before doing anything else and using super():

class MyConfigurable(Configurable):
    def __init__(self, config=None):
        super(MyConfigurable, self).__init__(config=config)
        # Then any other code you need to finish initialization.

This ensures that instances will be configured properly.

autoindent(parameter_s='')

Toggle autoindent on/off (deprecated)

cpaste(parameter_s='')

Paste & execute a pre-formatted code block from clipboard.

You must terminate the block with ‘–’ (two minus-signs) or Ctrl-D alone on the line. You can also provide your own sentinel with ‘%paste -s %%’ (‘%%’ is the new sentinel for this operation).

The block is dedented prior to execution to enable execution of method definitions. ‘>’ and ‘+’ characters at the beginning of a line are ignored, to allow pasting directly from e-mails, diff files and doctests (the ‘…’ continuation prompt is also stripped). The executed block is also assigned to variable named ‘pasted_block’ for later editing with ‘%edit pasted_block’.

You can also pass a variable name as an argument, e.g. ‘%cpaste foo’. This assigns the pasted block to variable ‘foo’ as string, without dedenting or executing it (preceding >>> and + is still stripped)

‘%cpaste -r’ re-executes the block previously entered by cpaste. ‘%cpaste -q’ suppresses any additional output messages.

Do not be alarmed by garbled output on Windows (it’s a readline bug). Just press enter and type – (and press enter again) and the block will be what was just pasted.

Shell escapes are not supported (yet).

automatically pull code from clipboard.

Examples

In [8]: %cpaste
Pasting code; enter '--' alone on the line to stop.
:>>> a = ["world!", "Hello"]
:>>> print(" ".join(sorted(a)))
:--
Hello world!
::

In [8]: %cpaste Pasting code; enter ‘–’ alone on the line to stop. :>>> %alias_magic t timeit :>>> %t -n1 pass :– Created %t as an alias for %timeit. Created %%t as an alias for %%timeit. 354 ns ± 224 ns per loop (mean ± std. dev. of 7 runs, 1 loop each)

paste(parameter_s='')

Paste & execute a pre-formatted code block from clipboard.

The text is pulled directly from the clipboard without user intervention and printed back on the screen before execution (unless the -q flag is given to force quiet mode).

The block is dedented prior to execution to enable execution of method definitions. ‘>’ and ‘+’ characters at the beginning of a line are ignored, to allow pasting directly from e-mails, diff files and doctests (the ‘…’ continuation prompt is also stripped). The executed block is also assigned to variable named ‘pasted_block’ for later editing with ‘%edit pasted_block’.

You can also pass a variable name as an argument, e.g. ‘%paste foo’. This assigns the pasted block to variable ‘foo’ as string, without executing it (preceding >>> and + is still stripped).

Options:

-r: re-executes the block previously entered by cpaste.

-q: quiet mode: do not echo the pasted text back to the terminal.

IPython statements (magics, shell escapes) are not supported (yet).
