Currently the error is rather ambiguous and does not inform folks that
static import is not supported in the repl. This overrides the default
error message with one that is more informative.

Closes: #33576

The logic should probably be moved here:

// Remove stack trace.

I've updated PTAL

@BridgeAR I don't think we need to check the length on this. If someone is explicitly messing with the stack size I'm pretty happy that this feature might fail for them. Thoughts?

lib/repl.js Outdated
e.message = 'Cannot use import statement inside the Node.js repl, ' +
'please use dynamic import instead';
const splitStack = StringPrototypeSplit(e.stack, '\n');
splitStack[4] = `SyntaxError: ${e.message}`;

we could alternative find which item in the array starts with SyntaxError rather than by default using the 5th item

That sounds better to me. There is in fact similar code to determine that line below. It'll only be triggered in case there's no uncaughtException listener though.

Updated to use regex PTAL

Is it not possible to just fix static import? That would be most user friendly and I would rather have that. I guess it might be tricky to implement it though?

@BridgeAR AFAIK there is no way to implement static import in the REPL. I could be wrong, but in lieu of a solution to that this seems like the next best thing.

Currently the error is rather ambiguous and does not inform folks that
static import is not supported in the repl. This overrides the default
error message with one that is more informative.
