Fix/tree sitter parsing expression failure

[helgardferreira]

🤔 What's changed?

A helper function stripBlacklistedExpressions to help with tree-sitter's parsing in certain edge cases where parsing is currently erroneous.

⚡️ What's your motivation?

We're currently using playwright-bdd so that we can use playwright as our test runner and cucumber for BDD. Unfortunately, the language server is currently not working for the decorator syntax for playwright-bdd which can be found here.

The reason for this seems to be that the version of tree-sitter that is used by @cucumber/language-service is unable to parse TypeScript files that contain decorators for classes. This PR is an interim fix for that until either tree-sitter addresses the issue (if the issue is on their behalf - I'm not sure) or until @cucumber/language-service changes the tree-sitter parsing to work as expected.

Is anyone going to review this? As it stands right now Helgard's unofficial cucumber extension on VSCode marketplace is the only one that works for our project.

@helgardferreira, the here link appears to be broken. Would you be able to provide an updated link or according example?

[helgardferreira]

@kieran-ryan Oh sorry, I think the docs might have gotten updated. I've updated the link which can be found here: https://vitalets.github.io/playwright-bdd/#/writing-steps/decorators

Cheers, those examples appear to work for me; is there perhaps a variation of other code combined with these decorators that's causing the issue; if any examples? Would be great to get the different cases added to the unit tests as a test data source.

I can definitely make examples. The current specific issue we're running into is in a proprietary codebase but I'll create an environment to demonstrate the issue 🙂
