From 036de7e68bb880108b046d783d0dde5cffb46a63 Mon Sep 17 00:00:00 2001 From: Denys Shabalin Date: Wed, 12 Apr 2017 12:48:45 +0200 Subject: [PATCH] Refactor sbt plugin to make it more idiomatic (#630) * Remove shared library mode that has never been tested * Make nativeClang and nativeClangPP a task * Make nativeCompileOptions and nativeLinkingOptions to be a task * Introduce linker result object to aggregate all the info linker produces * Make resource scope to be tighter, just around linking and codegen, not around the whole pipeline * Simplify OptimizerDriver API * Update sbt docs Fixes #562 --- build.sbt | 25 +- docs/user/sbt.rst | 45 +- .../sbtplugin/ScalaNativePlugin.scala | 28 +- .../sbtplugin/ScalaNativePluginInternal.scala | 640 +++++++++--------- .../run/external-dependencies/build.sbt | 72 +- .../external-dependencies/project/Check.scala | 83 --- .../scala/scalanative/codegen/CodeGen.scala | 82 ++- .../scala/scalanative/linker/Linker.scala | 35 +- .../scala/scalanative/linker/Result.scala | 61 ++ .../scala/scalanative/optimizer/Driver.scala | 20 +- .../scalanative/optimizer/inject/Main.scala | 3 +- .../scala/scalanative/tools/Config.scala | 32 +- .../scala/scalanative/tools/package.scala | 10 +- .../scala/scala/scalanative/CodeGenSpec.scala | 22 +- .../scala/scalanative/FrameworkTest.scala | 8 +- .../scala/scala/scalanative/LinkerSpec.scala | 17 +- .../scala/scalanative/OptimizerSpec.scala | 6 +- .../scalanative/optimizer/DriverSpec.scala | 27 +- .../optimizer/pass/AsLoweringTest.scala | 5 +- .../main/scala/java/lang/ExceptionSuite.scala | 34 +- .../scala/java/util/regex/PatternSuite.scala | 4 - .../scala/scala/scalanative/util/Scope.scala | 2 +- 22 files changed, 594 insertions(+), 667 deletions(-) delete mode 100644 scripted-tests/run/external-dependencies/project/Check.scala create mode 100644 tools/src/main/scala/scala/scalanative/linker/Result.scala diff --git a/build.sbt b/build.sbt index 7b37cb1819..574864a9c4 100644 --- a/build.sbt +++ b/build.sbt @@ -1,7 +1,7 @@ +import java.io.File.pathSeparator import scala.util.Try import scalanative.tools.OptimizerReporter -import scalanative.sbtplugin.ScalaNativePluginInternal.nativeOptimizerReporter -import java.io.File.pathSeparator +import scalanative.sbtplugin.ScalaNativePluginInternal._ val toolScalaVersion = "2.10.6" @@ -272,27 +272,6 @@ lazy val nativelib = .in(file("nativelib")) .settings(libSettings) .settings(mavenPublishSettings) - .settings(compile in Compile := { - val clang = findClang(nativeClang.value) - val clangpp = findClangPP(nativeClangPP.value) - - val source = baseDirectory.value - val compileSuccess = - IO.withTemporaryDirectory { tmp => - IO.copyDirectory(baseDirectory.value, tmp) - scala.scalanative.sbtplugin.ScalaNativePluginInternal - .compileCSources(clang, - clangpp, - tmp, - nativeGC.value, - streams.value.log) - } - if (compileSuccess) { - (compile in Compile).value - } else { - sys.error("Compilation failed") - } - }) lazy val javalib = project diff --git a/docs/user/sbt.rst b/docs/user/sbt.rst index 474afb3e5d..9055c763cf 100644 --- a/docs/user/sbt.rst +++ b/docs/user/sbt.rst @@ -35,33 +35,24 @@ and now you can write your first application in ``./src/main/scala/HelloWorld.sc now simply run ``sbt run`` to get everything compiled and have the expected output!
