RE: How to change status line %W output format

[Liu, Yuanzhe]

Thanks for your kindly explain😊.
Now I have synced with upstream and ready for compiler my own screen, my 
current HEAD is "commit 854c3673bb69a07d0ebaa52c2cd31eebaeaaca2c".
But the code seems changed a lot, I can't find the code location you mentioned 
now.
So could you please give me some advice base on my newer code?

Regards,
Yuanzhe

Hi,

if you want instand feedback, it's currently impossible without editing source 
code.

You could replace AddWindows here with your own version:
https://git.savannah.gnu.org/cgit/screen.git/tree/src/screen.c?h=screen-v4#n2708

AddWindows definition:
https://git.savannah.gnu.org/cgit/screen.git/tree/src/process.c?h=screen-v4#n5512

Another alternative I guess is to use callbacks to print window list, but I 
don't have such script at hand.
You could use
screen -Q windows
and then format it into your desired format, while callback would feed it into 
screen.
Problem with it would be that, you wouldn't get instand feedback onto your 
window situation.
