Thanks, Yegappan, that's very helpful. I think these extensions
will make things much smoother.
I was trying to find something in the help regarding the meaning
of a "window id". Though there are several functions that
accept and return these, I can't find anything that defines
them.
Perhaps the help could contain a definition of window ID that
answers these questions:
- How does a window ID differ from a window number?
- Since getloclist() accepts either a window number or a window
ID for the first argument, these two number spaces must be
non-overlapping; how does Vim ensure this property?
- Are window IDs unique across tab pages?
- Are window IDs more permanent in some way than window numbers?
For example, if I rearrange the windows in a tab page, do the
window numbers change but the window IDs remain the same?
That empirically seems to be the case when I move the QuickFix
window around within a tab page; is this guaranteed? The
window id empirically changes when closing and reopening the
QuickFix window and when moving the QuickFix window to another
tab; does that mean that the window ID stays the same until
the window is closed?
Also, in the help for getwininfo() (vim 7.4.2222) is this
sentence:
"""
Without an information about all the windows in all the tab
pages is returned.
"""
Should that start with "Without {winid}, information about..."?
Thanks,
Michael Henry
