shx-for-emacs VS readline-complete

I use the wonderful shx package for making M-x shell a more usable shell, and I use shell-pop for popping up shell buffers that are automatically cd'd to the current files directory.

I swear by running bash in shell-mode enhanced by shx so I can properly use SSH.

Also note that Emacs is a fully GUI application, like I said, it depends on libgdk and libcairo2, and Emacs has support for inline graphics. Take a look at the shx-for-emacs extension to see an example of it (screenshot). Please take a look at Nicolas P. Rougier's GitHub page, he has some of the most beautiful Emacs GUI configurations (for example, this screenshot).

Here is link number 1 - Previous text "shx"

I have been extremely satisfied with using plain shell mode combined with shx. With shx I can open a file directly from the shell with :edit, and ssh with :ssh. I find that a plain old shell running bash when combined with emacs is just so powerful.

It should be techincally possible given packages like bash-completion exists. The problem is tho that most REPLs disable readline stuff when they encounter a DUMB terminal for obvious reasons AFAIU. Some have a flag to force the fancy stuff on but some don't. A quick search for "emacs readline completion" yields this package -- https://github.com/emacsmirror/readline-complete -- it needs a new breath of life to turn it into capf I suppose.
