Underlined variables.

https://www.jetbrains.com/idea/whatsnew/ :

This is an interesting new code quality feature, but it seems to operate differently from the normal code warnings.

IntelliJ doesn't display a clickable light bulb to the left offering the option of disabling the warning for the variable / method / class level.

Can I change something in my config to enable that optional suppression?

If not, is there a @SuppressWarnings() label that I can employ manually?

Thanks

Hello Adam,

Actually it's not an inspection. Do you need to completely disable underlining?

OK. Are you saying that if it's not an inspection, I can't disable it in the code for the one or two situations where I don't want to see it, as I would for any of inspection? 

I don't want to disable it completely.

However where I'm really concerned about variable re-assignment, I just make the variable final. 

Yse, it's not possible to suppress it for custom place in code.

I guess I'll disable it then. I've got too many variables in my code that are, well, variable! 

To be honest, this is a very unwelcome feature... Could you guys disable it by default?

It will make `board[i][i]` looks like `board[i][j]` during when looping a 2d array. It took me 38 minutes to debug during leetcode contest. 

Let me put more comments on this feature. If a developer doesn't want a variable to be reassigned, I will use final keyword to enforce it. It's a compiler error, which is safer and more effective. You can also use const in c++, but c# doesn't have this feature....

A underscore warning is really unnecessary.

However, I do like Intellij. 

Thanks for your feedback, I've submitted a usability problem you can vote for: https://youtrack.jetbrains.com/issue/IDEA-207835.

Thank you, Serge.  This has been bothering me for months.  If anyone else ends up here trying to disable this anti-feature, please go vote for the issue above.  I suggested just changing it to an inspection which I can't imagine anyone would have a problem with.

Now I'll go disable it.

Been trying to hunt down the issue regarding that underline.

Hope this gets turned off by default too.

Phew, at least you can turn it off. :)

In Java, it might be useful for parameters, for a control variable in the for loop this is just ridiculous. I am turning this off.

There is black dotted underlining happening that does not relate to static parameters.  For example, I am calling a java static function from groovy and the function name is underlined.  This feature should be disabled until a "what am I thinking?" addition is added at least pointing to what is triggering the underline even if there is no code correction.  The other annoying thing about this is it looks very similar to the "can't find declaration" notification, which is something that we shouldn't ignore.  In the original example, control click enters the function, so it is obviously either an internal glitch or something different.

Jeff,

Any inspection could be disabled by hovering on the underlined word and clicking the light bulb. See https://i.imgur.com/7MvDCeD.png

This post is about reassigned local variables. So, If your question is not related to reassigned local variables, it is better to create a new post. 

Thank you.
