Module: core.magics.script

Magic functions for running cells in various scripts.

1 Class

class IPython.core.magics.script.ScriptMagics(shell=None)

Bases: IPython.core.magic.Magics

Magics for talking to scripts

This defines a base %%script cell magic for running a cell with a program in a subprocess, and registers a few top-level magics that call %%script with common interpreters.

__init__(shell=None)
kill_bg_processes()

Kill all BG processes which are still running.

killbgscripts(_nouse_='')

Kill all BG processes started by %%script and its family.

shebang(line, cell)
%shebang [--proc PROC] [--bg] [--err ERR] [--out OUT]

Run a cell via a shell command

The %%script line is like the #! line of script, specifying a program (bash, perl, ruby, etc.) with which to run.

The rest of the cell is run by that program.

Examples

In [1]: %%script bash
   ...: for i in 1 2 3; do
   ...:   echo $i
   ...: done

optional arguments:
--proc PROC The variable in which to store Popen instance. This is used only when –bg option is given.
--bg Whether to run the script in the background. If given, the only way to see the output of the command is with –out/err.
--err ERR The variable in which to store stderr from the script. If the script is backgrounded, this will be the stderr pipe, instead of the stderr text itself.
--out OUT The variable in which to store stdout from the script. If the script is backgrounded, this will be the stdout pipe, instead of the stderr text itself.
