Let's rewrite all major userspace tools this way, or maybe use emacs ? I don't know.

ps: not sarcastic at all.

kachnuv_ocasek• 12 years ago

I agree with your second idea. I don't see how it's different from Vim or Emacs.

agumonkey7• 12 years ago

It's just a good idea that was never (AFAIK) done for shell only interactions. Often good to be able to have progressive enhancement (people not allowed to install emacs say).

What I was impressed by is

  git checkout $(git branch | percol)

to select the branch name interactively from a menu. How would you do that in Vim or Emacs?

Check out vipe, which is included in Joey Hess' moreutils [1]. It lets you edit a pipe in vim. You can use it the same way as percol.

The gif animation is ridiculously fast. Can't really see what's going on. If it's not needed, you could just delete it.

rcthompson2• 12 years ago

The gif animation is confusing to me because the shell appears to be extensively customized, so I can't tell what is percol and what is crazy zshell customization.

Zikes• 12 years ago

Turning off that distracting auto-fu would help a lot, I think.

vbit• 12 years ago

Agree. There is already completion going on from the shell and it's very distracting. The demo should use a dead simple shell.

nsxwolf• 12 years ago

I found it to be not too fast once I started focusing on what was being input instead of the changes to the output.

zsh already has a built in menu selection system that looks a lot like the animated .gif here. Check out "zstyle ':completion:*' menu select"

rcthompson2• 12 years ago

I believe that is what is being shown. The tool is (I think) being demonstrated in a zshell with that feature (and probabaly countless others) turned on, so it is difficult to tell what is shell and what is percol. Or maybe not. The point is I don't know.

I just tried it out in bash, it works pretty much the same way it does in the gif. This description of the functionality in the readme is succinct:

percol

- receives input lines from stdin or a file,

- lists up the input lines,

- waits for your input that filter/select the line(s),

- and finally outputs the selected line(s) to stdout.

You made my day.

Reminds me of Gary Bernhardt's selecta [1].

I worked on a similar project: a tool that (primarily) tees it's stdin to your tty before you decide how to continue your pipe[1], which is a little more general, though it's admittedly less polished or nice. I think there's an interesting space in making the process of writing commands more interactive, though doing that really well will involve an intelligent solution to the problem of commands with side effects.

Actually I downloaded

https://github.com/hchbaw/auto-fu.zsh

after seeing this README.md.

fzf [1] is another nice alternative to this.
