missing semicolon (";") detection improvement

[ThomasBarberot]

Hello.

Feature request description
I help some new RPG developers using VSCode/Code for i. And the most encoureted error is a missing semicolon (" ; ") at the end of an instruction, especially at the declaration level (dcl-s and dcl-ds).

And sometimes, I don't see it quickly and spend a lot of time to seek something else.

RDi comparison
In VSCode, when I remove an ending semicolon in a DS declaration (or after a calculation intruction), it appears this way:

As you can see, there is no warning to indicate that the second DS cannot be resolved because of the missing semicolon.

In RDi, the same member appears this way:

As you can see, on the line following the one where the semicolon is missing, there is a red cross to indicate the parsing issue.

Describe the solution you'd like
It would be great to indicate on the following line that the semicolon is missing, with a message or underlines like other errors.

Describe alternatives you've considered
I didnt't found anywhere to set on something to help to set focus on an error like missing semicolon. Perhaps I missed something.

Thanks for your great job around Code for i!

If you add a lint configuration file with valid indentation, you will get a bunch of warnings :) I will see about how we can add this.

I tried to apply your advice (I spent some time trying to find out how to activate the linter! I tried it a few months ago!).
And this is what I see with the linter solution (with the indentation):

If I remove the semicolon at the end of a calculation line, no warning appears:

If I remove the semicolon at the end of a calculation line and the second DS, no warning appears:

If I remove the semicolon at the end of a calculation line and the second DS and the first DS, warning appears:

So the solution is working, but not completely because all the cases of missing semicolon are not covered.
