2020-03-31 15:19:42 +0200 asked a question sage-shell-mode sending code region to sage-shell only loads file New to both python and sage. I have installed sage-shell-mode in emacs. I tested M-x run-sage, and it starts a shell. I created a test.sage file with three lines # -*- mode: sage -*- factor(100) 2+2  I send the code (either by C-c C-c, or first marking a region and then C-c C-r) to the sage shell. It only loads a file, as in sage: load('/tmp/sage_shell_moder97r9B/sage_shell_mode_temp.sage')  I expected it to show the results. I am using emacs 26.3 and sage 8.1 on Ubuntu 18.4. I have no special configuration in init.el other than (require 'sage-shell-mode) (sage-shell:define-alias)  Thank you for help.
