Sublime-syntax: regex to detect end of file (as opposed to end of line?

[ngppgn]

I’d want my syntax highlighting to detect unclosed brackets, by tinting as invalid_illegal the ending spaces of a file if their are in a context other than main.

For this, I was thinking of adding a match rule like this

  - match: \s*\Z
    scope: invalid.illegal

The problem is that \Z seems to be the same semantics as $ in sregex. So is there any other way to test with a regex in the syntax lexer wether we met the end of file as opposed to the end of line? Event in a line-based engine, one would thing that a special patter would be exposed to test if the line is the last line in the buffer without us having to resorts to linting the file.

No, there is no way to know when EOF is reached in a syntax definition - you are better off using a linter for such tasks as highlighting unclosed brackets than the syntax definition itself

That’s what I feared. I need to do research on making linters from scratch then
