""" Fun magic line editor for ipython
Use this to easily edit lists of strings gradually without crafting long
list comprehensions.
'l' is the magic variable name for every line (array element). Save the current
result (or more exactly, retrieve the last ipython computation result into
%led work area) by running '%led s'. Just run '%led' to show the current work
area data.
Example use:
[ipython]|25> setups = !ls *setup*.py
==
['eggsetup.py', 'setup.py', 'setup_bdist_egg.py']
[ipython]|26> setups
<26> ['eggsetup.py', 'setup.py', 'setup_bdist_egg.py']
[ipython]|27> %led s
Data set from last result (_)
<27> ['eggsetup.py', 'setup.py', 'setup_bdist_egg.py']
[ipython]|28> %led upper
cmd translated => l.upper()
<28> ['EGGSETUP.PY', 'SETUP.PY', 'SETUP_BDIST_EGG.PY']
[ipython]|29> %led
Magic line editor (for lists of strings)
current data is:
['eggsetup.py', 'setup.py', 'setup_bdist_egg.py']
[ipython]|30> %led upper
cmd translated => l.upper()
<30> ['EGGSETUP.PY', 'SETUP.PY', 'SETUP_BDIST_EGG.PY']
[ipython]|31> %led s
Data set from last result (_)
<31> ['EGGSETUP.PY', 'SETUP.PY', 'SETUP_BDIST_EGG.PY']
[ipython]|32> %led "n:" + l
<32> ['n:EGGSETUP.PY', 'n:SETUP.PY', 'n:SETUP_BDIST_EGG.PY']
[ipython]|33> %led s
Data set from last result (_)
<33> ['n:EGGSETUP.PY', 'n:SETUP.PY', 'n:SETUP_BDIST_EGG.PY']
[ipython]|34> %led l.
