如何在 Scala 控制台启动运行 scala 代码？

Question

每次 Scala 控制台 repl 启动时是否可以运行一些 Scala 代码（此代码必须更改 REPL 上下文）？

原以为可能会有一些 .scala 或类似的配置文件允许进行设置。

我的用例是运行在每次 REPL 启动时使用此代码：

Answer 1

name := "scala-playground"
version := "0.1-SNAPSHOT"
organization := "org.reactormonk"
scalaVersion := "2.11.7"

resolvers ++= Seq(
  "ScalaNLP Maven2" at "http://repo.scalanlp.org/repo",
  "Scala Tools Snapshots" at "http://scala-tools.org/repo-snapshots/",
  "Sonatype Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots/"
)

libraryDependencies ++= Seq(
  "org.scalatest" %% "scalatest" % "2.2.1",
  "io.argonaut" %% "argonaut" % "6.1",
  "com.github.alexarchambault" %% "argonaut-shapeless_6.1" % "1.0.0-M1",
  "com.github.pathikrit"  %% "better-files-akka"  % "2.15.0"
)

javaOptions += "-Xmx4g"
addCompilerPlugin("org.spire-math" %% "kind-projector" % "0.7.1")
initialCommands in console := """
import scalaz._, Scalaz._
//import shapeless._
"""

Answer 2

当运行 `sbt console`:

我创建了一个 %USERPROFILE%\.sbt[=13=].13\global.sbt 全局配置文件并向其中添加了启动代码：

initialCommands in console := """
    def viewdoc[A](a: A) {
    val name = a.asInstanceOf[AnyRef].getClass.getName
    val url = "http://www.scala-lang.org/api/current/index.html#"+name
    val pb = new ProcessBuilder("firefox",url)
    val p = pb.start
    p.waitFor
    }
"""

运行 sbt 控制台：

C:\WINDOWS>sbt console
