Module: terminal.interactiveshell¶
Subclass of InteractiveShell for terminal based frontends.
2 Classes¶
-
class
IPython.terminal.interactiveshell.TerminalMagics(shell)¶ Bases:
IPython.core.magic.Magics-
__init__(shell)¶
-
autoindent(parameter_s='')¶ Toggle autoindent on/off (if available).
-
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.
IPython statements (magics, shell escapes) are not supported (yet).
See also
paste- 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!
-
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).
See also
cpaste- manually paste code into terminal until you mark its end.
-
rerun_pasted(name='pasted_block')¶ Rerun a previously pasted command.
-
store_or_execute(block, name)¶ Execute a block, or store it in a variable, per the user’s request.

class
IPython.terminal.interactiveshell.TerminalInteractiveShell(ipython_dir=None, profile_dir=None, user_module=None, user_ns=None, custom_exceptions=((), None), **kwargs)¶ Bases:
IPython.core.interactiveshell.InteractiveShell-
ask_exit()¶ Ask the shell to exit. Can be overiden and used as a callback.
-
edit_syntax_error()¶ The bottom half of the syntax error handler called in the main loop.
Loop until syntax error is fixed or user cancels.
-
static
enable_gui(gui=None, app=None)¶ Switch amongst GUI input hooks by name.
-
exit()¶ Handle interactive exit.
This method calls the ask_exit callback.
-
interact(display_banner=None)¶ Closely emulate the interactive Python console.
-
mainloop(display_banner=None)¶ Start the mainloop.
If an optional banner argument is given, it will override the internally created default banner.
-
raw_input(prompt='')¶ Write a prompt and read a line.
The returned line does not include the trailing newline. When the user enters the EOF key sequence, EOFError is raised.
Parameters: prompt : str, optional
A string to be printed to prompt the user.
-
system(cmd)¶ Call the given cmd in a subprocess using os.system on Windows or subprocess.call using the system shell on other platforms.
Parameters: cmd : str
Command to execute.
