Ok, I understand the recursion problem !

Yes, I would like to have it works from inside ipython. I already have a 
magic called 'do' which takes a batch file as argument. At the moment, the 
batch file can only contain magics, because I use the magic() method to 
execute lines. Here is the code :

def magic_do(self, parameter_s=''):
    """ do magic command.
    """
    myParser = ILLParserTPG()
    cmd = 'do ' + parameter_s
    try:
        command = myParser(cmd)
        fileName = command['fileName']
        file_ = open(fileName, "r")
        for line in file_:
            if line[0] != '#':
                args = line.split()
                ipmagic(args[0], ' '.join(args[1:]))
        
    except SyntacticError:
        MessageLogger().error(sys.exc_info()[1])

InteractiveShell.magic_do = magic_do
del magic_do

I would like to treat both magic and python code here. But even in this 
magic, I get a recursion problem.
