Hello.
In a project using Scalafix, when Silencer-plugin is added to Dependency, RemoveUnused no longer works.
Can Scalafix be used simultaneously with silencer-plugin?
Or is the setting wrong?
Here is the project to reproduce.
https://github.com/rysh/example-scalafix-with-fatalwarnings
Since RemoveUnused depends on compiler warning, which is retrieved through SemanticDB, scalafix can't run RemovedUnused properly under slicener-plugin.
@olafurpg
Thank you for the advice. When I tried referring to the link destination, silencer was specified after semanticdb in scalacOptions. But sadly, it did not work yet.
Here is my build.sbt
https://github.com/rysh/example-scalafix-with-fatalwarnings/blob/master/build.sbt
[error] (dao / Compile / scalafix) scalafix.sbt.InvalidArgument: The semanticdb-scalac compiler plugin is required to run semantic rules like RemoveUnused.

[error] No warnings can be incurred under -Werror.// scalafix:off works, but when i add it i get Unused Scalafix suppression, this can be removed in the test output
also i'm seeing (what i believe is) unexpected behavior when calling .symbol on the Term representation of some code:
// code
Some(1).map(_ => 2).getOrElse(3)
// symbol
term.symbol // => scala/Option#getOrElse().is there some other way to get information about the whole term? i'm looking to determine the resulting type of the expression
RemoveUnused option available for Scala 2.13? https://scalacenter.github.io/scalafix/docs/rules/RemoveUnused.html
This error also suggests that it is missing:
[error] (server / Compile / scalafix) scalafix.sbt.InvalidArgument: Unknown input 'Scala213'. Expected one of: Default, Scala212, Scala211, Dotty, Sbt0137, Paradise211, Sbt1, Paradise212.
fool(bar, baz) to foo(bar)(baz)). I'm using patchLeft and patchRight to add the parentheses but am struggling a little bit to remove the comma without removing any other commas that might be in the code for bar and baz. Is there a suggested method for doing this?
:wave: hey all. I have a piece of logic that generates fair complicated scala code (not macro, the code gets dumped to disk and compiled). I've been using Scalameta for this (to get as much compile errors as possible before I even run the code generation), but now I'd like to inline comments into the generated code, which makes me realise that using scalameta to generate code was probably a huge mistake ...
In any case, now I'm fairly committed, and I wonder whether it'd be possible for me to call scalafix programmatically to add the comments where relevant, after the ASTs have been generated.
- Is it possible to use scalafix with only syntactic information (ie without semanticdb) ?
- If so, is there a piece of code I could look at to understand how the basics of calling scalafix programmatically ?
Hi. I am trying to implement a rule that rewrites any object that does not extends serializable to extend it, if it already extends others traits, to extend the original object and mix-in with said traits.
I am struggling a bit because intellij does not allow me to navigate to the source code and it makes it a bit hard to understand how to manipulate a SemanticDocument
@Baccata I would recommend using something like https://github.com/typelevel/paiges for code generation, even if it comes at the cost of having no compile errors when producing invalid code
There is an experimental Scalameta tree printer that has an explicit API for attaching leading/trailing comments, see https://github.com/scalacenter/scala-syntax/blob/59919fb39d36d46f9b5913c02b2f01927f85d881/tests/unit/src/test/scala/scala/meta/internal/prettyprinters/DocstringSuite.scala I don't think it's published however, you would need to copy the sources over to use it
I'm trying to follow the guide posted here: https://scalacenter.github.io/scalafix/docs/developers/setup.html
however on the g8 step (sbt new scalacenter/scalafix.g8 --repo="Repository Name") sbt loads and resolves some things then asks for a username and password. If i don't put those in the whole task fails with https://github.com/scalacenter/scalafx.g8.git: not authorized. Same error if i put my github username/password in
