Running VIM inside Sage Shell

edit

When I type %edit then 1+1 in vim (which is the editor of my system) and exit, it emits '1+1/n' which is not executed by SAGE. Any help?

See the documentation for the %edit magic. It's a little confusing, but it does not work exactly the same as entering the code directly in the interactive prompt. If you just write a bare expression like 1 + 1, although it will be evaluated, its results are not displayed. Instead you have to write something like print(1 + 1) if you want the results displayed when executing the code. The %edit command outputs the code entered as a string allowing you to do things like %edit _ to re-edit the previous code.
