Greetings. I am trying to emulate the << >> functionality of OCaml in python on cloud.sagemath.com. For instance, if I type:
<<stuff>>
I want it to call default_parser("stuff"). I have it working if << and >> are on the same line, but I want it to be able to span multiple lines. Here's my code:
from IPython.core.inputtransformer import (StatelessInputTransformer)
@StatelessInputTransformer.wrap
def quotations(line):
if line is not None:
line = line.replace("<<", 'default_parser("""')
line = line.replace(">>", '""")')
return line
ip = get_ipython()
ip.input_splitter.logical_line_transforms.append(quotations())
ip.input_transformer_manager.logical_line_transforms.append(quotations())
It can't handle this:
<<
stuff
>>
It replaces the << in the first line just fine, but apparently once it goes into triple quote mode, it stops calling my transformation function.
