问题
I have the scala format plugin in my multi project sbt repository.
addSbtPlugin("org.scalameta" % "sbt-scalafmt" % "2.3.2")
So in the sbt console if I run scalafmt it works fine
My build.sbt has:
scalafmtOnCompile := true
If I do a ~compile in sbt or just compile manually, it doesn't format my code during compilation.
What is wrong with my setup?
Also, running scalafmt works but it doesn't format my .scala files in /project like my Dependencies.scala file. Why is it ignoring these files?
I am using VS Code with metals also as my IDE.
回答1:
Scalafmt seeems to work in VSC with Metals out-of-the-box on my machine
Metals automatically uses Scalafmt to respond to formatting requests from the editor, according to the configuration defined in
.scalafmt.conf... if there is no.scalafmt.conf, upon receiving the first format request Metals will create the .scalafmt.conf file for you.
Simply execute Format Document command from Command Palette in VSC and it should format according to .scalafmt.conf. If you would like to continuously format and compile on every source change and scalafmtOnCompile is not working, then try executing in sbt
~scalafmt;compile
however format on compile is discouraged as per documentation
This option is discouraged since it messes up undo buffers in the editor and it slows down compilation. It is recommended to use "format on save" in the editor instead.
