How to emulate UltiSnips (expand if exact same label as snippet)

[ilan-schemoul]

Feature Description

Hi,
I want same behaviour as supertab + UltiSnips if my snippets is foo:
I type fo => it does not expand snippet. It opens menu
I type foo=>it expand immediately
I see that you have a section about supertab in keymaps but it works different.
I type fo=>it expands

In API I can get_selected_item to get the label of the snippet. But I don't see the API to get the currently text typed by User. I need it to check if it's the exact same as the snippet label
