Chain Commands

[raf912]

Dear all,

is there a way to pick one command with pet, do a pipe and then select another one with pet?
Would be nice if I can hit ^s again to select the next command.

Thank you in advance.

If you're using zsh you would need to set this widget definition in .zshrc:

function pet-select() {
  RBUFFER=$(pet search)
  CURSOR=$#BUFFER
  zle redisplay
}
zle -N pet-select
stty -ixon
bindkey '^s' pet-select

Thanks @jaroslawhartman , didn't even know this was possible! Do you mind if we add your GIF to the README?

@Raf1312 Your question is answered :)

For me, the bash solution from README.md doesn't work as expected.

I changed the function to:

function pet-select() {
  BUFFER=$(pet search)
  READLINE_LINE+="$BUFFER "
  READLINE_POINT=${#READLINE_LINE}
}

This works fine here.

Feedback appreciated! @RamiAwar

or even shorter:

function pet-select() {
  READLINE_LINE+="$(pet search) "
  READLINE_POINT=${#READLINE_LINE}
}

Assuming each command has all snipppets with a tag - e.g.:

$ pet list -t grep
Description: Suche nach einem Ausdruck in einer Datei:
    Command: grep "{{ausdruck}}" {{pfad/zu/datei}}
        Tag: grep
------------------------------
Description: Suche nach einem exakten Ausdruck:
    Command: grep {{[-F|--fixed-strings]}} "{{exakter_ausdruck}}" {{pfad/zu/datei}}
        Tag: grep
------------------------------
Description: Benutze erweiterte reguläre Ausdrücke (unterstützt `?`, `+`, `{}`, `()` und `|`) ohne Beachtung der Groß-, Kleinschreibung:
    Command: grep {{[-Ei|--extended-regexp --ignore-case]}} "{{ausdruck}}" {{pfad/zu/datei}}
        Tag: grep
------------------------------
Description: Zeige 3 Zeilen Kontext um [C], vor [B] oder nach [A] jedem Ergebnis:
    Command: grep {{--context|--before-context|--after-context}} 3 "{{ausdruck}}" {{pfad/zu/datei}}
        Tag: grep
------------------------------

... the search is pre-filtered for the specific command:

function pet-select() {
  local pre post command result
  pre=${READLINE_LINE:0:$READLINE_POINT} # left from cursor
  post=${READLINE_LINE:$READLINE_POINT} # right from cursor
  command=$(echo "${pre//*|/}" | awk '{print $1}') # real current cmd
  test "${pre: -1}" = " " || pre+=" " # append blank if cursor is directly after cmd
  if [ ${#command} -gt 0 ]; then
    # pet for the specific cmd and remove unneeded "command | sudo mycmd"
    result="$(pet search -t "$command" | sed "s/^\([^|]*|\s*\)\{0,1\}\(sudo\s\s*\)\{0,1\}\s*\b$command\b\s*//")"
  else
    result="$(pet search)" # global search if no cmd before cursor
  fi
  READLINE_LINE="$pre$result"
  READLINE_POINT=${#READLINE_LINE}
  READLINE_LINE+="$post"
}
