Bram - that makes total sense, thanks very much for your patience.
One further issue I'm seeing relates to how undos are processed.
Now with the following:
function EchoChanges(bufnr, start, end, added, changes)
redir >> /tmp/listener.log | echom getbufline(a:bufnr, 0, "$")
a:changes | redir END
endfunction
call listener_add("EchoChanges")
loaded via -u, with an initial file of:
Line 1
Line 2 #
Line 3
Line 4 #
Line 5
Line 6 #
and then executing the following commands:
:g/#/d
u
I see the following log line for the global command (which makes sense):
['Line 1', 'Line 3', 'Line 5'] [{'lnum': 2, 'col': 1, 'added': -1,
'end': 3}, {'lnum': 3, 'col': 1, 'added': -1, 'end': 4}, {'lnum': 4,
'col': 1, 'added': -1, 'end': 5}]
And then the following sequence as a result of the undo:
['Line 1', 'Line 3', 'Line 4 #', 'Line 5', 'Line 6 #'] [{'lnum': 4,
'col': 1, 'added': 1, 'end': 4}]
['Line 1', 'Line 2 #', 'Line 3', 'Line 4 #', 'Line 5', 'Line 6 #']
[{'lnum': 3, 'col': 1, 'added': 1, 'end': 3}]
['Line 1', 'Line 2 #', 'Line 3', 'Line 4 #', 'Line 5', 'Line 6 #']
[{'lnum': 2, 'col': 1, 'added': 1, 'end': 2}]
Now I'm guessing the undo is being processed step-by-step (so to
speak) in reverse.
So the first and second lines look wrong, because they appear to show
the buffer already has the "next" undo applied.
Again, apologies if (as is likely) I'm missing something obvious.
Thanks
