Question

Say I open a terminal emulator in Emacs with M-x ansi-term. This opens a buffer in Emacs with the shell of my choice. Say I then run ipython from this shell. Can I send code to this ipython session from another buffer with Python code in Emacs? If so how?

Answer 1

I have a minor mode for this purpose (except it is not IPython-specific and I mostly use it for shell scripts): isend-mode.

Here is how you would use it:

1. Open an ansi-term buffer:

   M-xansi-termRET/usr/bin/ipythonRET

2. Open the buffer with the code you want to execute, and associate it to the interpreter buffer:

   M-xisend-associateRET*ansi-term*RET

3. Hit C-RET in the python buffer to send the current line to the interpreter in the ansi-term buffer.
