invalid literal for int() with base 10. Probably tmux version incompatibility.

The plugin installed properly. After trying to execute a command or set a flag i got such the error.

22:38:30 ERRO invalid literal for int() with base 10: ''

The problem is there is no variable "#{window_marked_flag}". Current format window variables:

     window_active                   1 if window active
     window_activity                 Time of window last activity

     window_bigger                   1 if window is larger than client
     window_end_flag                 1 if window has the highest index
     window_flags           #F       Window flags
     window_format                   1 if format is for a window (not assuming the current)
     window_height                   Height of window
     window_id                       Unique window ID
     window_index           #I       Index of window
     window_last_flag                1 if window is the last used
     window_layout                   Window layout description, ignoring zoomed window panes
     window_linked                   1 if window is linked across sessions

❯ tmux -V
tmux 3.0a

May be in the older or newer versions the variable exists, i didn't check it.

I fixed it easily and can make a Pull Request, don't you mind about it? Simply changed definition of the has_marked_pane variable

from

    has_marked_pane = int(
        tmux("display", "-p", "-F", "#{window_marked_flag}", "-t", ranger_pane)
    )

to

    marks = tmux("display", "-p", "-F", "#{window_flags}", "-t", ranger_pane)
    # marks var contains for instance the following symbols "*MZ" or "*" if empty
    has_marked_pane = 'M' in marks

Hi,

Thanks for looking into this. It looks like the window_marked_flag was added in tmux==3.1 (see here).

I'd be happy if you'd like to submit your PR - it would be nice to support older versions of tmux.
