"""Define a macro for future re-execution. It accepts ranges of history,
filenames or string objects.
Usage:\\
%macro [options] name n1-n2 n3-n4 ... n5 .. n6 ...
Options:
-r: use 'raw' input. By default, the 'processed' history is used,
so that magics are loaded in their transformed version to valid
Python. If this option is given, the raw input as typed at the
command line is used instead.
-q: quiet macro definition. By default, a tag line is printed
to indicate the macro has been created, and then the contents of
the macro are printed. If this option is given, then no printout
is produced once the macro is created.
This will define a global variable called `name` which is a string
made of joining the slices and lines you specify (n1,n2,... numbers
above) from your input history into a single string. This variable
acts like an automatic function which re-executes those lines as if
you had typed them. You just type 'name' at the prompt and the code
executes.
The syntax for indicating input ranges is described in %history.
Note: as a 'hidden' feature, you can also use traditional python slice
notation, where N:M means numbers N through M-1.
For example, if your history contains (print using %hist -n )::
44: x=1
45: y=3
46: z=x+y
47: print x
48: a=5
49: print 'x',x,'y',y
you can create a macro with lines 44 through 47 (included) and line 49
called my_macro with::
In [55]: %macro my_macro 44-47 49
Now, typing `my_macro` (without quotes) will re-execute all this code
in one pass.
You don't need to give the line-numbers in order, and any given line
number can appear multiple times. You can assemble macros with any
lines from your input history in any order.
The macro is a simple object which holds its value in an attribute,
but IPython's display system checks for macros and executes them as
code instead of printing them when you type their name.
You can view a macro's contents by explicitly printing it with::
print macro_name
