Line and column numbers are wrong

code: print(
output: 2:1: error: expected expression in list of expressions
expected: 1:7: error: expected expression in list of expressions

This seems to be the expected result.

When the following command is executed,

$ sh -c "echo 'print(' | swift -"

The following output is obtained. This output matches the SwiftFiddle output.

<stdin>:2:1: error: expected expression in list of expressions

^

The same results are obtained when the following Swift file (test.swift) is created,

print(

and the following command is executed.

$ swift test.swift

Oh, I see. I tested only on https://www.jdoodle.com/execute-swift-online/.

It makes sense that the problem isn't in a line that doesn't exist yet.
How can we highlight errors if the line doesn't exist? 🤔 I think Xcode adds an extra line for that.

Yes, Parser tries to find the closing bracket to the end of the file, so it will give an error for a line number that does not exist.
After the error is printed, you can add a line corresponding to the line number in error, for example, to get the expected result.
