Window ID / Window Title / Pane number missing

[pbartyik]

use tmux_interface;
use tmux_interface::session::SESSION_ALL;

fn main() {
    let sessions = tmux_interface::Sessions::get(SESSION_ALL).unwrap();

    for s in sessions {
        let session_name = s.name.unwrap();
        let ws = tmux_interface::Windows::get(&session_name, 64).unwrap();
        println!("Session {}", session_name);
        for w in ws {
            println!("{:?}", w);
        }
    }
}

Session 0 has two windows, one unnamed (id 0) and one named asd (id 1).
Session 0 window id 1 has two panes.

Output of program:

Session 0
Window { active: None, activity: None, activity_flag: None, bell_flag: None, bigger: None, end_flag: None, flags: Some(WindowFlag(2)), form
at: None, height: None, id: None, index: None, last_flag: None, layout: None, linked: None, name: None, offset_x: None, offset_y: None, pan

 let ws = tmux_interface::Windows::get(&session_name, tmux_interface::window::WINDOW_ALL).unwrap();

Hi,

thank you for your feedback, for choosing/using the library.

If you are calling the function Windows::get():

let ws = tmux_interface::Windows::get(&session_name, 64).unwrap();

it expects one or many WINDOW_XXXXXX flags as the secondary argument. In your example 64 is equal to 1 << 6 (bitwise shift left) and it is equal to WINDOW_FLAGS flag. This produces the following string as request command to tmux:

tmux list-windows -t session_name -F "#{window_flags}"

and the resulting Windows structure will be something like:

Vec {
  // first window, all fields except window_flag are empty
  Window {
    None, None, None, ..., Some(WindowFlag(WINDOW_FLAG_DEFAULT), None, None, ...}
  },
  // second window
  Window {
    None, None, None, ..., Some(WindowFlag(WINDOW_FLAG_CURRENT), None, None, ...}
  },
  ...
}

You are right you can request all supported fields by using WINDOW_ALL flag:

let ws = tmux_interface::Windows::get(&session_name, WINDOW_ALL).unwrap();

or you can manually set the bitflag combination for fields you need, for example WINDOW_ID | WINDOW_FLAGS | WINDOW_NAME | WINDOW_HEIGHT | WINDOW_WIDTH

let ws = tmux_interface::Windows::get(
  &session_name, 
  WINDOW_ID | WINDOW_FLAGS | WINDOW_NAME | WINDOW_HEIGHT | WINDOW_WIDTH
).unwrap();

It is made to reduce the size of the text exchanging between tmux and user application.

Sorry for missing documentation which would help you faster. I mark this as documentation required issue.

Please be advised, the library (especially dev branch) is still in experimental development stage and it is not well tested:

many features are not implemented, or can fail
some APIs/structures/names/... can be changed in future
some design patterns of the library can be changed
etc…

Thanks, digged solution out from source code :)
