bpmagic

bpmagic is a library to save and load boilerplate code. With a few simple commands, you can save and load bits of frequently used code to speed up programming in iPython and Jupyter.

Install

bpmagic is up on pip, so you can simply call: pip install bpmagic

Loading bpmagic

To load the bpmagic namespaces, you can use the load_ext magic function: %load_ext bpmagic To prevent typing this everytime, you can add this to your ipython profile startup (mine is in /.ipython/profile_default/startup/) and place the above command into a *.ipy file (you can name it whatever you want, I used bpmagic.ipy)

Save

Using the %%isave magic function, you can write and save a chunk of code into a new bpmagic namespace. For example:

	%%isave data
	import pandas as pd
	import numpy as np
	import scipy as sp

This will save your current cell of code into the namespace data. If the namespace is already defined, you can overwrite using the -o flag:

	%%isave plot -o
	import matplotlib.pyplot as plt
	import seaborn as sns
	%matplotlib inline

Load

Using the %iload function, you can load up 1 or more profiles at once. For example:

%iload data plot

This will load the boiler plate code for data and plot and replace the cell that contained %iload with:

	# data
	import pandas as pd
	import numpy as np
	import scipy as sp

	# plot
	import matplotlib.pyplot as plt
	import seaborn as sns
	%matplotlib inline

Delete

If you pass a profile name after %idelete, you will remove that profile name. Example: %idelete data

Rename

Passing in the old name followed by the new profile name will change the name of a profile: %irename plot plotting

List

To get a list of current profiles, simply call %ilist in ipython, and it will return a list of all of your current profiles.
