Transparent Pipe(tp)

This project is inspired by akavel/up.
tp is a terminal-based application for display the result of the commands at every keystroke.
Make it easy to chain commands for such as string manipulation.

It provides two displays.

1. stdout from last pipe.
2. live preview of the command result.

Shell integration

It can be synchronized shell's linebuffer and tp's inputfield.
The below config is the zsh integration.
keymappings: ctrl + |

function transparent-pipe() {
  BUFFER="$(tp -c "${BUFFER}|")"
  CURSOR=$#BUFFER
}
zle -N transparent-pipe
bindkey "^|" transparent-pipe

Limitation

tp executes the command at every keystroke. There is possibility to execute dangerous commands such as rm.
So, tp is only supported specific string manipulation commands. Any other commands will be executed when you pressed |, not every keystroke.
Also, tp is not supported redirections(<, >).

supported commands:
awk,cut,egrep,grep,head,jq,nl,sed,sort,tail,tr,uniq,vgrep,wc,yq
