I think I forgot that the recommended way to do unto/redo has been changed
since I wrote that script. Also, you can directly set p.b or p.v.b and
those changes will stick. Here's one I found in Leo's code base that does
that and uses the newer undo system:
def insertBodyTime(self: Self, event: LeoKeyEvent = None) -> None:
"""Insert a time/date stamp at the cursor."""
c, p, u = self, self.p, self.undoer
w = c.frame.body.wrapper
undoType = 'Insert Body Time'
if g.app.batchMode:
c.notValidInBatchMode(undoType)
return
bunch = u.beforeChangeBody(p)
w.deleteTextSelection()
s = self.getTime(body=True)
i = w.getInsertPoint()
w.insert(i, s)
p.v.b = w.getAllText()
u.afterChangeBody(p, undoType, bunch)
