New key binding: prepend-sudo about prezto HOT 19 CLOSED

alias _='sudo' is defined in alias.zsh. Why don't you use that?

from prezto.

I don't think that I have a free and meaningful key for binding this. I will not break C-s. I could change _ to s, and you could type C-a, s, SPACE. That's two more keys unfortunately. You don't need sudo that often, do you?

from prezto.

Clobbering C-a is a bad idea, since it's the default prefix for screen commands.

from prezto.

@gwjo I'm not clobbering C-a. That's the default key binding for moving the cursor to the beginning of the line in the Emacs layout. I'm telling @giddie to go to the begging of the line, type s, then spacebar, then hit enter. How GNU Screen users deal with Emacs layouts is not my concern.

from prezto.

To be clear: this isn't a quick way of typing "sudo" (although that does work); this prepends "sudo" to the current line. For instance, I'm halfway through typing a command when I realise I need to be root to do it, so I press C-s, and "sudo" is added to the start of the line. That way, I don't have to throw away the line and retype it.

I administer several ArchLinux servers at work and one at home. I need "sudo" pretty frequently. Maybe that's unusual, though.

BTW, can't I scroll through history search using arrow keys?

Anyway, I'm happy with this in my fork, but it took me a while to figure out how to do this, and I wonder how many other people might benefit from stumbling upon this code in OMZ and thinking "Huh, that's a neat idea".

from prezto.

@sorin-ionescu Ah; I see. Yeah, I could use C-a and C-e to achieve the same thing; I didn't honestly know about those bindings. That takes more keystrokes, though. I like my binding :) If you think it's not going to be useful to anyone else, I understand.

from prezto.

Typing C-a, s, space, C-e is certainly more work than C-s. But, I still can't see where I can bind it. You can execute bindkey -L to see the current bindings.

from prezto.

Do you know where C-r and C-s came from for history-incremental-pattern-search? I'm considering switching them with C-n and C-p (history-substring-search), which are already bound to the up and down keys. That would free up my C-s (and maybe I could use C-r for my push-line-or-edit binding).

from prezto.

@giddie They come from Emacs, but all bindings are found in keyboard.zsh.

from prezto.

I can bind this to C-X C-S in emacs mode. TBD in Vi mode.

from prezto.

I've chosen Escape-S in Vi mode. How does that sound to you?

from prezto.

It's probably going to be C-X C-S for both. It's easier to type than ESC-S or C-[ C-S.

from prezto.

Agreed. C-x is also self-insert in vi-mode. The idea of having "special" bindings like this tidied under C-x appeals to me. It gives me scope to add more if I want.

from prezto.

There are quite a few C-X bindings. Don't go trigger happy now. Check before you bind.

from prezto.

I'm not seeing any bindings under C-x in vi-mode, which is all I really care about when it comes to my own use. If I were to suggest a new binding for general consumption, I'd be sure to check Emacs-mode doesn't already have that key bound :)

from prezto.

There is a problem with this implementation. It's too dumb. It prepends sudo at the beginning of the line when it should prepend at the beginning of the current command in order to work in multi-command lines or multi-line commands.

from prezto.

True; this is OK for my needs, though Thanks for including this :)

from prezto.

I don't include anything for one man's needs. It has to be useful to many. That said, making this command aware will be a pain. It's probably not worth it.

from prezto.

Absolutely, I would hope not!
