Ping @marmeladema. Sorry for bothering, just wanted to know is this repo still under development? And is there a chance that this PR will be merged?

Not part of the project but for our project we implemented startswith and endswith as functions instead of operators as it is more flexible approach.

Yeah this kind of use-cases is exactly what functions are for, as it doesn't require any special syntax.

[amiremohamadi]

Right, but why we have contains as an operator?

[RReverser]

Because Wireshark has it and this library was designed to support similar syntax: https://www.wireshark.org/docs/wsug_html_chunked/ChWorkBuildDisplayFilterSection.html

If it wasn't for that, it could've been just a function too, yeah.
