Setting Window Width with a Script

[Jeff Shepherd]

Is iTerm2 AppleScript-able? I'm trying to set the width of a window using an AppleScript like the following

tell application "/Applications/iTerm.app"

  activate

    tell current window

      set width of current session to 800 -- Set the desired width in pixels

    end tell

end tell

but am getting an error "iTerm got an error: Can’t make width of current session of current window into type specifier."

Is it possible to set the iTerm2 window with a script?

You can’t directly resize a session to a pixel size. Instead, resize the window by modifying its bounds:

tell application "iTerm2"

set current_window to current window

tell current session of current window

set new_width to 800

set current_window_bounds to bounds of current_window

set current_height to (item 4 of current_window_bounds) - (item 2 of current_window_bounds)

set bounds of current_window to {item 1 of current_window_bounds, item 2 of current_window_bounds, (item 1 of current_window_bounds) + new_width, (item 2 of current_window_bounds) + current_height}

end tell

end tell

Alternately, if you know the number of pixels per column, you can change the number of columns:

tell application "iTerm2"

set columns of current session of current window to 100

end tell
