I'm testing my plugin by running it in-process like this:
type PluginMessage = StoreReporter#Info
def runPlugin(fileName: String): List[PluginMessage] = {
val settings = new Settings
settings.outputDirs setSingleOutput (curDir + "/target")
settings.classpath.tryToSet(List(
"project/boot/scala-" + scalaVersion + "/lib/scala-compiler.jar" +
":project/boot/scala-" + scalaVersion + "/lib/scala-library.jar"))
val reporter = new StoreReporter
val compiler = new Global(settings, reporter) {
override protected def computeInternalPhases() {
super.computeInternalPhases
for (phase <- new AlacsPlugin(this).components)
phasesSet += phase
}
}
(new compiler.Run).compile(List(testPrefix + fileName))
reporter.infos.to开发者_C百科List
}
However, given the slow speed of scalac
I'd really like for compilation to end after a certain phase (specifically, after my plugin runs). Unfortunately Global.cancel
doesn't have the intended effect. How might I do this?
scalac has an argument explicitly for this purpose. As of 2.9.0.RC2 you can specify at the command line:
-Ystop-after:<phasename>
And in earlier versions:
-Ystop:<phasename>
To do the equivalent directly from a Settings
instance, this is defined as stopAfter
(or stop
in earlier versions)
