如何使用 scalariform 自动格式化 sbt 构建文件?

问题描述

我想用 scalariform 格式化我的 sbt 构建文件.启动 sbt 时是否可以在构建定义本身上运行 scalariform?

I'd like to format my sbt build files with scalariform. Is it possible to run scalariform on the build definition itself when starting sbt?

推荐答案

把这个放到 project/scalariform.sbt:

addSbtPlugin("com.typesafe.sbt" % "sbt-scalariform" % "1.2.0")

这在 scalariform.sbt 中:

import scalariform.formatter.preferences._
import ScalariformKeys._

lazy val BuildConfig = config("build") extend Compile
lazy val BuildSbtConfig = config("buildsbt") extend Compile

val foo: Int => Int = {
  case 1 => 1
  case     2 => 2
}

noConfigScalariformSettings

inConfig(BuildConfig)(configScalariformSettings)

inConfig(BuildSbtConfig)(configScalariformSettings)

scalaSource in BuildConfig := baseDirectory.value / "project"

scalaSource in BuildSbtConfig := baseDirectory.value

includeFilter in (BuildConfig, format) := ("*.scala": FileFilter)

includeFilter in (BuildSbtConfig, format) := ("*.sbt": FileFilter)

format in BuildConfig := {
  val x = (format in BuildSbtConfig).value
  (format in BuildConfig).value
}

preferences := preferences.value.
  setPreference(AlignSingleLineCaseStatements, true).
  setPreference(AlignParameters, true)

运行:

helloworld> build:scalariformFormat
[info] Formatting 1 Scala source {file:/Users/eed3si9n/work/helloworld/}helloworld(buildsbt) ...
[info] Reformatted 1 Scala source {file:/Users/eed3si9n/work/helloworld/}helloworld(buildsbt).
[success] Total time: 1 s, completed Oct 5, 2013 2:58:45 PM

魔法！

val foo: Int => Int = {
  case 1 => 1
  case 2 => 2
}
