Valid way to exclude specific consrutctions(for ex. loops)

[alexander-petuhov]

Hello. We are thinking about excluding some specific constructions from parsing - for example loops. I saw there are limitation abilities in "Safe parser" documentation section https://github.com/lunet-io/scriban/blob/master/doc/runtime.md#safe-runtime which can help to limit them, but is there valid way to forbid some of them at all? Thanks.

Unfortunately, there is nothing builtin. You can always iterate on the AST and remove the loops (but there is no a visitor pattern currently provided, so you have to manually go through the statements). If you feel to have this at parse time, feel free to send a PR, modifying the ParserOptions and the Parser to discard loop after parsing them (and log an error).
