Observations

This problem is limited to MacOS
Other emacs modes also encounter this problem, for example there are some bug reports for ESS.

It's 2018. Let's try to fix this.

I tried "stty cbreak" and it worked as described there.

tom111 commented 5 years ago

So shall we modify commint-mode so that it does not use "canonical input mode"?

DanGrayson commented 5 years ago

No, for then C-d will stop working to indicate EOF.

tom111 commented 5 years ago

Shouldn't emacs be able to do all the things that canonical input mode does? If I delete a character in M2-mode, is it deleted by emacs or by the shell in its internal buffer? I'll have to read up on what the emacs mode actually does...

DanGrayson commented 5 years ago

I'm not sure what your question is about -- character deletion in an emacs buffer is handled by emacs.

mikestillman commented 5 years ago

What is the status of this? I too find it annoying that I cannot use f11 to send a long line to M2...!

tom111 commented 5 years ago

I don’t know how to solve this. Other projects have this problem too, but no solution had emerged when I looked into it last year.
