add support for opening code block delimiters too

[newbiePythonist]

Hello, how can i avoid having to type the opening delimiter in order to get automatically inserted the closing one? Given a lua example where "|" is the cursor, i'd like to get from this:

if condition|

to this:
if condition then
|
end

or in a bash example:
while condition|

while condition do
|
done

At the moment i still have to type "then" or "do" in order to tell the plugin i'm opening a code block, i'd like to just press and see it open and closes automatically my code block. Thanks
