Is it possible to combine magics in IPython / Jupyter?
Sometimes you want to use several magics at the same time. Now I know you can use
%%time
%%bash
ls
But when I make my own commands this chaining doesn't work...
from IPython.core.magic import register_cell_magic
@register_cell_magic
def accio(line, cell):
print('accio')
exec(cell)
results in an error when using
%%accio
%%bash
ls
What should I use rather than exec?

Nothing :) just that it doesn't seem to be able to chain :)

you have to apply the IPython special transformations, to run the nested magic with the cell, like the %%time magic:
@register_cell_magic
def accio(line, cell):
ipy = get_ipython()
expr = ipy.input_transformer_manager.transform_cell(cell)
expr_ast = ipy.compile.ast_parse(expr)
expr_ast = ipy.transform_ast(expr_ast)
code = ipy.compile(expr_ast, '', 'exec')
exec(code)
or simply call run_cell:
@register_cell_magic
def accio(line, cell):
get_ipython().run_cell(cell)
result:
In [1]: %%accio
...: %%time
...: %%bash
...: date
...:
accio

In IPython source code, they almost always use a class for creating magic statements because they can hold values, and I think that's what your looking for.
