Determine the window name/number in iTerm2

Question

I am using iTerm2 on MacOS (Sierra). I have multiple instances of iterm2 running, each has a title that are prefixed with a number which increments with each running window.

I would like to run a shell command to return this number on the command line, does any one know how to get this information?

I am looking for something like:

$ iterm_get_number()
2

Answer 1

I was able to get the names using applescript, the following script dumps a list of the open iTerm windows. Since I am interested in using these names in a python script I included a small snippet for doing this as well.

get_window_names.applescript

on run
    set returnNames to {}
    tell application "iTerm"
        repeat with theWindow in windows
            tell theWindow
                set end of returnNames to get name
            end tell
        end repeat
    end tell
    return returnNames
end run

python for extracting information from above script

out = subprocess.check_output(['osascript', 'get_window_names.applescript'])
print [x.strip() for x in out.split(',')]
