TableCell with unescaped backslash is escaped in the AST value (original) (raw)

👓 What did you see?

While creating a prettier plugin for gherkin file, I found out that the TableCell with unescaped backslash is escaped in the AST.

Example from escaped_pipes.feature :

is reprensented in the AST like this:

{ "location": { "column": 22, "line": 10 }, "value": "\o\no\" }

So it's impossible to reconstitute the original string.

✅ What did you expect to see?

An unescaped backslash in the node value for unescaped backslash

📦 Which tool/library version are you using?

Javascript librairies :

• @cucumber/gherkin: 24.1.0"
• @cucumber/messages: 19.1.4

🔬 How could we reproduce it?

Probably run the cucumber test stack.

📚 Any additional context?

If this is intended, then how can we regenerate the original node value ?
According to https://cucumber.io/docs/gherkin/reference/#table-cell-escaping a backslash can not be alone (while not really explicitly said).

If the cucumber test data allow parsing this un-escaped backslash, is it a bug or a feature ? Some tool allow this comportment, like PHP library behat.

Thanks
