Switch profile in Konsole from command line?

Question

I know that its possible to set profile for new tab, but what if i need to switch profile for current tab?

Answer 1

From Changing Konsole colors in KDE using the shell the solution is quite simple but cover color

konsoleprofile colors=WhiteOnBlack
# or
konsoleprofile colors=GreenOnBlack

Where the value come from menu Settings > Edit Current Profile… > select Appearance tab.

Tmux

You need to wrap the command in the passthrough escape sequence inside tmux session, otherwise it won't do anything:

printf '\033Ptmux;\033\033]50;konsoleprofile colors=GreenOnBlack\007\033\\'

Here is are tiny helpers I put in my ~/.zshrc:

# Konsole color changing
theme-night() {
  switch-term-color "colors=TomorrowNightBlue"
}
theme-light() {
  switch-term-color "colors=Tomorrow"
}
switch-term-color() {
  arg="${1:-colors=Tomorrow}"
  if [[ -z "$TMUX" ]]
  then
    konsoleprofile "$arg"
  else
    printf '\033Ptmux;\033\033]50;%s\007\033\\' "$arg"
  fi
}

Answer 2

As noted by Luis Bocanegra in his answer this can be done by calling setProfile method of org.kde.konsole.Session Konsole's dbus interface.

Example using qdbus-qt6:

qdbus-qt6 $KONSOLE_DBUS_SERVICE $KONSOLE_DBUS_SESSION org.kde.konsole.Session.setProfile 'Profile 1'

Example using dbus-send:

dbus-send --dest=$KONSOLE_DBUS_SERVICE $KONSOLE_DBUS_SESSION --type=method_call org.kde.konsole.Session.setProfile string:'Profile 1'

For example to change Konsole's profile based on current directory in ZSH define the following function in either ~/.zprofile or ~/.zshrc:

chpwd () {
  case "$PWD/" in
    $HOME/some/directory/*)
      konsole_profile='Profile 1'
      ;;
$HOME/another/directory*)
  konsole_profile='Profile 2'
  ;;

$HOME/*)
  konsole_profile='home'
  ;;

*)
  konsole_profile='default'
  ;;

esac
  dbus-send --dest=$KONSOLE_DBUS_SERVICE $KONSOLE_DBUS_SESSION --type=method_call org.kde.konsole.Session.setProfile string:$konsole_profile
}
