Re: The launch script

you want to start something in a new urxvt tab, don't you?

Not really, just the usual toggle behavior, actually no idea what I was doing there (probably typos) as it seems to work now.

p.s. I should probably change all this wbar statements to something like

(launchee iceweasel || iceweasel)

so wbar it will fall to its standard behavior if launchee script is not found.

Re: The launch script

Here is a new version of the launcher script.
Now using window id's exclusively in stead of pids.

#!/bin/bash
#.....
# there has to be at least one parameter, the name of the file to execute
if (( $# == 0 ));then
  echo "Usage: $(basename $0) executable_name [parameters]"
  exit 1
fi

has_element () {
  local e
  for e in "${@:2}"; do [[ "$e" == "$1" ]] && return 0; done
  return 1
}

launchee=$(basename "$1")

# test to see if program is already running
declare -a launchee_win_ids
launchee_win_ids=( $(wmctrl -lx | awk -v pattern="$launchee" 'BEGIN {IGNORECASE = 1} $3 ~ pattern {print $1}' ) )
if (( ${#launchee_win_ids[@]} ));
then 
    # means at least one launchee process  must already be running
    active_window_id=$(printf '0x%8x' $(xdotool getwindowfocus))
    active_window_id=${active_window_id// /0}

    # is acitve_window_pid one of the already running launchee?
    if has_element "$active_window_id" "${launchee_win_ids[@]}"; then
        # launched app is currently in focus, so do nothing
        # xdotool getactivewindow windowminimize
        :
    else
        # launchee instance is not in focus, so raise and bring to focus
        # which one do you bring into focus if there are many?
        # First one is easiest
        wmctrl -i -a "${launchee_win_ids[0]}"
    fi
else
    # start it up
    "$@"&
fi

exit 0

I have changed the behaviour slightly:
If you now launch an application from an already running instance of that application, it now does nothing.
The old version then minimised the current instance.

Try it out and let me know for which application if it does not work for you

BTW:
The script contains bash code to transform a decimal window_id to a hexadecimal one.

Re: The launch script

@xaos52, nice, slightly moded to enable minimize/maximize behavior and to shut-up the shellcheck.net
https://raw.githubusercontent.com/bront … n/launchee

Any purpose of the ":" line?

A quick web search with "bash colon" came up with:

: (a colon)

    : [arguments]

    Do nothing beyond expanding arguments and performing redirections. The return status is zero.

and

you can usually use either : or true. Both are specified by POSIX, and some find true easier to read. However there is one interesting difference: : is a so-called POSIX special built-in, whereas true is a regular built-in.

Re: The launch script

Right, sort of an empty event? So if
# xdotool getactivewindow windowminimize
is enabled it serves no purpose?
