Bart,
Thanks for pointing this out, and thanks for providing the file that
reproduces it. And, I can't think of any good reason or excuse that
would explain why I did it that way.
I agree that a Python programmer would expect it to do the insert
rather than the replacement.
OK, we could modify generateDS.py so that instead of this:
def insert_window(self, index, value): self.window[index] = value
it generates the following:
def replace_window_at(self, index, value): self.window[index] = value
def insert_window_at(self, index, value): self.window.insert(index, value)
I was worried that there may be some code out there that depends on
the current behavior. So, I've removed the old generated name
completely (insert_window, ...). This change would cause code that
uses the old, exiting "insert_xx" method to throw an exception,
which would alert the user to the need to change his/her code.
And, it should be relatively easy to search existing code that uses
a generated module for "insert_" to determine whether a change is
needed.
I've made the above fix. This fix also makes an equivalent change
for "old style" getter and setter names (command line option
--use-getter-setter). So, for example, with command line option
--use-getter-setter=old, it generates replaceWindowAt and
insertWindowAt.
What do you think?
You can get the patched version at Bitbucket:

If you get a chance to try it, please let me know what you think.
