This commit makes it possible to quickly index a classpath of a project. This makes it possible to jump to definition from a project source file to a dependency source file. Note that this does not make is possible to jump to definition from dependency sources to dependency sources. While testing this feature, I extended the Jars utility to fetch -sources jars instead of regular jars and adapted the scala.meta.Classpath.deep method to read entries of jar files and report errors using our logging infrastructure. --- build.sbt | 2 +- .../scala/meta/languageserver/Ctags.scala | 238 +++++++++++++++ .../languageserver/DefinitionIndexer.scala | 111 ------- .../scala/meta/languageserver/Jars.scala | 25 +- .../scala/meta/languageserver/CtagsTest.scala | 287 ++++++++++++++++++ .../DefinitionIndexerTest.scala | 59 ---- 6 files changed, 544 insertions(+), 178 deletions(-) create mode 100644 metaserver/src/main/scala/scala/meta/languageserver/Ctags.scala delete mode 100644 metaserver/src/main/scala/scala/meta/languageserver/DefinitionIndexer.scala create mode 100644 metaserver/src/test/scala/scala/meta/languageserver/CtagsTest.scala delete mode 100644 metaserver/src/test/scala/scala/meta/languageserver/DefinitionIndexerTest.scala diff --git a/build.sbt b/build.sbt index a48418e47b3..249b0139d0d 100644 --- a/build.sbt +++ b/build.sbt @@ -24,10 +24,10 @@ lazy val metaserver = project resolvers += "dhpcs at bintray" at "https://dl.bintray.com/dhpcs/maven", libraryDependencies ++= List( "io.monix" %% "monix" % "2.3.0", + "com.lihaoyi" %% "pprint" % "0.5.3", "io.get-coursier" %% "coursier" % coursier.util.Properties.version, "io.get-coursier" %% "coursier-cache" % coursier.util.Properties.version, "ch.epfl.scala" % "scalafix-cli" % "0.5.3" cross CrossVersion.full, - "com.geirsson" %% "scalafmt-core" % "1.3.0", "org.scalatest" %% "scalatest" % "3.0.1" % "test", "org.scalameta" %% "testkit" % "2.0.1" % "test" ) diff --git a/metaserver/src/main/scala/scala/meta/languageserver/Ctags.scala b/metaserver/src/main/scala/scala/meta/languageserver/Ctags.scala new file mode 100644 index 00000000000..f2c30a6f134 --- /dev/null +++ b/metaserver/src/main/scala/scala/meta/languageserver/Ctags.scala @@ -0,0 +1,238 @@ +package scala.meta.languageserver + +import java.io.IOException +import java.nio.charset.StandardCharsets +import java.nio.file.FileVisitResult +import java.nio.file.Files +import java.nio.file.Path +import java.nio.file.SimpleFileVisitor +import java.nio.file.attribute.BasicFileAttributes +import java.util.zip.ZipInputStream +import scala.collection.GenSeq +import scala.collection.parallel.mutable.ParArray +import scala.meta.Defn +import scala.meta.Defn +import scala.meta.Name +import scala.meta.Pat +import scala.meta.Pkg +import scala.meta.Source +import scala.meta.Template +import scala.meta.Term +import scala.meta.Tree +import scala.meta.Type +import scala.meta.parsers.ParseException +import scala.meta.transversers.Traverser +import scala.util.control.NonFatal +import com.typesafe.scalalogging.LazyLogging +import org.langmeta.inputs.Input +import org.langmeta.inputs.Position +import org.langmeta.internal.io.FileIO +import org.langmeta.internal.io.PathIO +import org.langmeta.io.AbsolutePath +import org.langmeta.io.Fragment +import org.langmeta.io.RelativePath +import org.langmeta.semanticdb._ + +/** + * Syntactically build a semanticdb containing only global symbol definition. + * + * The purpose of this module is to provide "Go to definition" from + * project sources to dependency sources without indexing classfiles or + * requiring dependencies to publish semanticdbs alongside their artifacts. + * + * One other use-case for this module is to implement "Workspace symbol provider" + * without any build-tool or compiler integration.

10 Nov 2017 00:17:11 +0100 Subject: [PATCH 04/35] Implement Go to definition in classpath using Ctags module. The implementation in this commit is very hacky since I'm not sure how we can jump to definition inside entries of jars. I'm sure it's possible to just give the jar uri or something and everything automagically works. We index the entire classpath for every entry in the project/config matrix without any deduplication. This needs to be optimized. Most of the work was to get the compiler to correctly download the sources jars from the classpath. I had to wrap the call to `Jars.fetch` inside of a `Future` to unblock the compiler for future updates. This is a bug that needs to be fixed, we should not be randomly sprinkling blocks inside `Future { ... }`. --- README.md | 2 +- build.sbt | 2 +- .../scala/meta/languageserver/Compiler.scala | 48 ++++++++++++++++--- .../scala/meta/languageserver/Formatter.scala | 5 +- .../scala/meta/languageserver/Jars.scala | 10 ++-- .../scala/meta/languageserver/Main.scala | 3 +- .../ScalametaLanguageServer.scala | 22 ++++----- .../meta/languageserver/SymbolIndexer.scala | 27 +++++++++-- .../a/src/main/scala/example/User.scala | 4 ++ .../a/src/test/scala/example/UserTest.scala | 9 +++- test-workspace/build.sbt | 3 +- .../ScalametaLanguageServerPlugin.scala | 13 +++++ 12 files changed, 115 insertions(+), 33 deletions(-) diff --git a/README.md b/README.md index bd314acfb8e..9719b739ac0 100644 --- a/README.md +++ b/README.md @@ -28,7 +28,7 @@ Please share your thoughts in -

While profiling the javaparser ctags indexer I found out that it was only indexing around 10k loc/s. The scalameta parser is super slow and it can index 30-40k loc/s, so this is unacceptable. This commit, reimplements the java indexer using qdox, which seems to be able to spin through 250k loc/s, which is a nice improvement :) The qdox api is also a lot nicer, so this turned out to be a big win! --- build.sbt | 1 + .../scala/meta/languageserver/Compiler.scala | 27 +++-- .../meta/languageserver/CompilerConfig.scala | 78 +++++++++--- .../scala/meta/languageserver/Effects.scala | 18 +++ .../meta/languageserver/SymbolIndexer.scala | 7 +- .../meta/languageserver/ctags/Ctags.scala | 81 ++++++++++--- .../languageserver/ctags/CtagsIndexer.scala | 3 + .../meta/languageserver/ctags/JavaCtags.scala | 40 +++++-- .../meta/languageserver/ctags/QDoxCtags.scala | 112 ++++++++++++++++++ .../a/src/main/scala/example/User.scala | 7 +- .../a/src/test/scala/example/UserTest.scala | 9 +- test-workspace/build.sbt | 3 + .../ScalametaLanguageServerPlugin.scala | 31 +++-- 13 files changed, 338 insertions(+), 79 deletions(-) create mode 100644 metaserver/src/main/scala/scala/meta/languageserver/Effects.scala create mode 100644 metaserver/src/main/scala/scala/meta/languageserver/ctags/QDoxCtags.scala diff --git a/build.sbt b/build.sbt index 5bf1ce1b56b..03469420e4c 100644 --- a/build.sbt +++ b/build.sbt @@ -26,6 +26,7 @@ lazy val metaserver = project "io.monix" %% "monix" % "2.3.0", "com.lihaoyi" %% "pprint" % "0.5.3", "com.github.javaparser" % "javaparser-core" % "3.4.3", + "com.thoughtworks.qdox" % "qdox" % "2.0-M7", "io.get-coursier" %% "coursier" % coursier.util.Properties.version, "io.get-coursier" %% "coursier-cache" % coursier.util.Properties.version, "ch.epfl.scala" % "scalafix-cli" % "0.5.3" cross CrossVersion.full, diff --git a/metaserver/src/main/scala/scala/meta/languageserver/Compiler.scala b/metaserver/src/main/scala/scala/meta/languageserver/Compiler.scala index cb84268882a..3457a7ff5d2 100644 --- a/metaserver/src/main/scala/scala/meta/languageserver/Compiler.scala +++ b/metaserver/src/main/scala/scala/meta/languageserver/Compiler.scala @@ -1,6 +1,5 @@ package scala.meta.languageserver -import java.io.File import java.io.PrintStream import java.util.concurrent.ConcurrentHashMap import scala.collection.mutable @@ -12,6 +11,7 @@ import scala.tools.nsc.reporters.StoreReporter import com.typesafe.scalalogging.LazyLogging import langserver.core.Connection import langserver.messages.MessageType +import monix.eval.Task import monix.execution.Scheduler import monix.reactive.MulticastStrategy import monix.reactive.Observable @@ -30,13 +30,15 @@ class Compiler( val documentPublisher: Observable[Document] = myDocumentPublisher private val indexedJars: ConcurrentHashMap[AbsolutePath, Unit] = new ConcurrentHashMap[AbsolutePath, Unit]() -
