Show nowarn / Wconf filters for a warning with @nowarn("verbose") #10985

That is so cool! TIL! and I just made a tweak on dotty about nowarn and didn't notice. Not that I didn't believe you, but I had to try it out on my test file. |

Every code base should have That doesn't work yet. |

Changing compiler flags is much more tedious than adding an annotation to the source and rebuilding. Scala 3 For Scala 2, I looked through the settings. Scoped So maybe |
As already implemented in Scala 3 ``` scala> @nowarn("v") def f = try 1 ^ warning: A try without a catch or finally is equivalent to putting its body in a block; no exceptions are handled. Applicable -Wconf / @nowarn filters for this warning: msg=<part of the message>, cat=other, site=f def f: Int ```

flags vs annotations is sad but true. Also counter-intuitive from an old school perspective. Modifying source is heavyweight, but because of the "build tool", flipping an option is heavier. I don't use an IDE, although previously I used Eclipse for Java projects, but I can see the "local" use case: there is some weirdness in my code, it shows a red squiggle or perhaps amber, I want to click an icon to show what I can do to silence the squiggle. That workflow is entirely local. The missing piece is still an audit to tell me what warnings were modified (locally suppressed) in my code. |
