(global-set-key "\C-cy" 'my-execute-line)
(global-set-key "\C-cr" 'sh-execute-region)
not in the same way as the macro-using-solutions.
I had the same idea as you and wrote almost the same code as
you, but then I realized that
sh-execute-region does *NOT* use the runing *shell*
but rather forks a sub-shell which only lives for the execution
This very different to what the OP (and I) wanted.
But I agree that it would much nicer to have real elisp
functions that checked for existence *shell* used it where
possible, or started it otherwise, etc etc.
I append some unfinished code,
for anyone to take and improve.
However, *the real* solution would most probably use comint-*
functions and variables the same way that the ess-eval-*
