But when I typesetting, as following blue circle of picture. pic2

The font color change to red, I think that font color should not be changed as red.

I have this problem, too. I think this is same as #30.

I have done some test, which shows that this input xxx was matched to Tags or entity.name.tag...

Ok, I found the problem...

If we write Verilog HDL code like

module asdf (
    input some_input
);

Then input some_input will be matched to an instantiation_patterns in syntaxes/verilog.tmLanguage#L156, whose pattern string is ^\s*([a-zA-Z][a-zA-Z0-9_]*)\s+([a-zA-Z][a-zA-Z0-9_]*)(?<!begin|if)\s*(?=\(|$). That is the reason why there will be incorrect highlighting color.

Maybe we can change the pattern string to ^\s*([a-zA-Z][a-zA-Z0-9_]*)\s+([a-zA-Z][a-zA-Z0-9_]*)(?<!begin|if)\s*(?=\() which deleted the last |$. However, I am not sure weather there is any side effects.
