Inconsistencies in ansi-terminal

[rahulmutt]

When working with the shell, I've noticed that there is a difference between the text you see and the text that gets sent in certain cases.

Suppose I use something like 'lein repl' for Clojure inside of ansi-terminal. When I press Backspace, it doesn't show that the text is deleted, but in fact it is deleted (as shown by the result from the repl). Similarly if you press 'x' on something, it shows that the character is deleted under the cursor, but the string sent to the shell is the original string. So the solution is straightforward:

(1) In shell mode, if the 'Backspace' key is pressed, additionally perform the function of the 'x' key.
(2) In shell mode, if the 'x' key is pressed, additionally perform the function of the 'Backspace' key.

This bug has forced me to use a normal terminal emulator for basic repl work. This bug also happens when you paste text into the terminal from the external clipboard. It also occurs with 'sbt'.

I'm seeing a similar bug in both ansi- and multi-term. I find this particularly bothersome because, on OS X, I use text expander snippets system wide. These show as being pasted into the terminal but do not execute. I have also found that text cannot be pasted into terminal using the standard OS X command-v (note that I use the osx layer), but must rather be put into the terminal from normal mode using put. Interestingly, eshell does not exhibit this problem. It would be great if the emacs ansi- and multi-terms could be made to behave more consistently with other terminals in this regard.

OP said this:

Pretty much all editions I make in evil-normal-state to what is written in the terminal show up in the command line, but then when I press enter, the result is as though they were ignored. This applies to deleting chars with dw or x, and pasting, in particular.

Also, I cannot change the position of the cursor in normal state. Say, I start escaping from insert-state to normal-state, pressing h twice to go left, and then pressing i again. Then if I type, my editions will show up at the place the cursor used to be.

I am reporting this here because it seems related, but am not sure. Maybe it is even expected or known behavior?

Also, this seems not to have anything to do with the shell. I mean, bash, zsh and the like. However, eshell works as expected. I would settle on it if I wasn't so addicted to zsh.
