Resize to relative screen size

[domvo]

I would like a command that lets me resize a window to 1/3 of the screen and inversely the other one to 2/3. Since I work with different external monitors (with different resolutions) relative instead of absolute numbers would be great.

If this is already achievable I would appreciate a cue into the right direction.

I'm not seeing this, other than using an external keybinding tool to do the calculation based on screen width (example: Hammerspoon) and then calling aerospace resize width X from that.

[incanus]

Building off of this, I made a quick-and-dirty script called ~/bin/aerowidth.sh that looks like this:

#!/usr/bin/env sh

WIDTH=$(osascript -e 'tell app "Finder" to get bounds of window of desktop' | sed -e 's/0, 0, //' -e 's/, .*//')

if [ $1 == 1 ]; then
  TARGET=$(bc -e "$WIDTH / 3")
elif [ $1 == 2 ]; then
  TARGET=$(bc -e "$WIDTH / 2")
elif [ $1 == 3 ]; then
  TARGET=$(bc -e "2 * $WIDTH / 3")
fi

aerospace resize width $TARGET

Then I call it with these keybindings:

alt-cmd-1 = 'exec-and-forget ~/bin/aerowidth.sh 1'
alt-cmd-2 = 'exec-and-forget ~/bin/aerowidth.sh 2'
alt-cmd-3 = 'exec-and-forget ~/bin/aerowidth.sh 3'

This binds these to current window to 1/3, 1/2, or 2/3 of the current screen width.

I guess I could make this work with the exec-and-forget command.

Claude told me to do it like this: osascript -e 'tell application "Finder" to get bounds of window of desktop' | cut -d',' -f3

I made this script but it has two issues:

• It resizes the window but doesn't resize the layout the window is in. It seems the window breaks out of the layout.
• The sizing is off by a bunch.

#!/usr/bin/env sh

AEROSPACE_STATE="/tmp/aerospace.state"

WIDTH=$(osascript -e 'tell app "Finder" to get bounds of window of desktop' | sed -e 's/0, 0, //' -e 's/, .*//')

echo "Width: $WIDTH"

AEROSPACE_CYCLE=$(cat "$AEROSPACE_STATE" 2>/dev/null)

case "$AEROSPACE_CYCLE" in
  "third")
    AEROSPACE_CYCLE="half"
    TARGET=$(bc -e "$WIDTH / 2")
    echo $TARGET
    ;;
  "half")
    AEROSPACE_CYCLE="twothird"
    TARGET=$(bc -e "$WIDTH / 3 * 2")
    echo $TARGET
    ;;
  "twothird")
    AEROSPACE_CYCLE="third"
    TARGET=$(bc -e "$WIDTH / 3")
    echo $TARGET
    ;;
  *)
    AEROSPACE_CYCLE="half"
    TARGET=$(bc -e "$WIDTH / 2")
    echo $TARGET
  ;;
esac

echo "$AEROSPACE_CYCLE" > "$AEROSPACE_STATE"

echo "Cycle: $AEROSPACE_CYCLE, Target: $TARGET"

aerospace resize smart $TARGET

Fixed it here:

#!/usr/bin/env sh

AEROSPACE_STATE="/tmp/aerospace.state"

# Get the focused monitor info from aerospace
MONITOR_INFO=$(aerospace list-monitors --focused)
MONITOR_ID=$(echo "$MONITOR_INFO" | awk '{print $1}')
MONITOR_NAME=$(echo "$MONITOR_INFO" | cut -d'|' -f2 | xargs)

WIDTH=$(system_profiler SPDisplaysDataType -json | \
  jq -r ".SPDisplaysDataType[0].spdisplays_ndrvs[] | select(._spdisplays_displayID == \"$MONITOR_ID\") | ._spdisplays_resolution" | \
  awk '{print $1}')

echo "Width: $WIDTH"

AEROSPACE_CYCLE=$(cat "$AEROSPACE_STATE" 2>/dev/null)

case "$AEROSPACE_CYCLE" in
  "third")
    AEROSPACE_CYCLE="half"
    TARGET=$(bc -e "$WIDTH / 2")
    echo $TARGET
    ;;
  "half")
    AEROSPACE_CYCLE="twothird"
    TARGET=$(bc -e "$WIDTH / 3 * 2")
    echo $TARGET
    ;;
  "twothird")
    AEROSPACE_CYCLE="third"
    TARGET=$(bc -e "$WIDTH / 3")
    echo $TARGET
    ;;
  *)
    AEROSPACE_CYCLE="half"
    TARGET=$(bc -e "$WIDTH / 2")
    echo $TARGET
  ;;
esac

echo "$AEROSPACE_CYCLE" > $AEROSPACE_STATE

echo "Cycle: $AEROSPACE_CYCLE, Target: $TARGET"

That would be great because getting the correct resolution from the OS is a bit of an annoyance.

That would still leave the cycling state to be stored somewhere?

I wrote a script that does exactly this: https://gist.github.com/Leftium/14026b69b98125ff547974dcb1c52332#file-aerospace-cycle-size

(actually it does a little more, but the size cycling a la Raycast is very convenient.)

# Sample usage in ~/.aerospace.toml

# Cycle window size (auto-detects dimension based on layout)
alt-shift-s = ['exec-and-forget ~/.config/bin/aerospace-cycle-size']

# Cycle window sizes directly
alt-shift-w = ['exec-and-forget ~/.config/bin/aerospace-cycle-size width']
alt-shift-h = ['exec-and-forget ~/.config/bin/aerospace-cycle-size height']
