From cf5fb5fdfd477e0bb4ffa0e4fec3a8ec01bf5cf1 Mon Sep 17 00:00:00 2001 From: Li Haoyi Date: Sun, 31 Dec 2017 22:56:45 -0800 Subject: Split Acyclic/Jawn/BetterFiles tests into their own `integration/` test suite. Those tests now download a snapshot of the relevant git repo rather than vendoring the files, and use a bare `build.sc` instead of having the build object be included in the test classpath. Tests pass using `sbt integration/test`, but `mill integration.test` still doesn't work --- scalalib/src/main/scala/mill/scalalib/Lib.scala | 2 +- scalalib/src/main/scala/mill/scalalib/Module.scala |

-val f = File("/User/johndoe/Documents") // using constructor -val f1: File = file"/User/johndoe/Documents" // using string interpolator -val f2: File = "/User/johndoe/Documents".toFile // convert a string path to a file -val f3: File = new JFile("/User/johndoe/Documents").toScala // convert a Java file to Scala -val f4: File = root/"User"/"johndoe"/"Documents" // using root helper to start from root -val f5: File = `~` / "Documents" // also equivalent to `home / "Documents"` -val f6: File = "/User"/"johndoe"/"Documents" // using file separator DSL -val f7: File = "/User"/'johndoe/'Documents // same as above but using Symbols instead of Strings -val f8: File = home/"Documents"/"presentations"/`..` // use `..` to navigate up to parent -``` - -**Note**: Rename the import if you think the usage of the class `File` may confuse your teammates: -```scala -import better.files.{File => ScalaFile, _} -import java.io.File -``` -I personally prefer renaming the Java crap instead: -```scala -import better.files._ -import java.io.{File => JFile} -``` - -### File Read/Write -Dead simple I/O: -```scala -val file = root/"tmp"/"test.txt" -file.overwrite("hello") -file.appendLine().append("world") -assert(file.contentAsString == "hello\nworld") -``` -If you are someone who likes symbols, then the above code can also be written as: -```scala -import better.files.Dsl.SymbolicOperations - -file < "hello" // same as file.overwrite("hello") -file << "world" // same as file.appendLines("world") -assert(file! == "hello\nworld") -``` -Or even, right-associatively: -```scala -import better.files.Dsl.SymbolicOperations - -"hello" `>:` file -"world" >>: file -val bytes: Array[Byte] = file.loadBytes -``` -[Fluent Interface](https://en.wikipedia.org/wiki/Fluent_interface): -```scala - (root/"tmp"/"diary.txt") - .createIfNotExists() - .appendLine() - .appendLines("My name is", "Inigo Montoya") - .moveToDirectory(home/"Documents") - .renameTo("princess_diary.txt") - .changeExtensionTo(".md") - .lines -``` - -### Streams -Various ways to slurp a file without loading the contents into memory: - ```scala -val bytes : Iterator[Byte] = file.bytes -val chars : Iterator[Char] = file.chars -val lines : Iterator[String] = file.lineIterator //file.lines loads all lines in memory -``` -Note: The above APIs can be traversed at most once e.g. `file.bytes` is a `Iterator[Byte]` which only allows `TraversableOnce`. -To traverse it multiple times without creating a new iterator instance, convert it into some other collection e.g. `file.bytes.toStream` - -You can write an `Iterator[Byte]` or an `Iterator[String]` back to a file: -```scala -file.writeBytes(bytes) -file.printLines(lines) -``` - -### Encodings -You can supply your own charset too for anything that does a read/write (it assumes `java.nio.charset.Charset.defaultCharset()` if you don't provide one): -```scala -val content: String = file.contentAsString // default charset - -// custom charset: -import java.nio.charset.Charset -file.contentAsString(charset = Charset.forName("US-ASCII")) - -//or simply using implicit conversion from Strings -file.write("hello world")(charset = "US-ASCII") - ``` - -Note: By default, `better-files` [correctly handles BOMs while decoding](core/src/main/scala/better/files/UnicodeCharset.scala). -If you wish to have the [incorrect JDK behaviour](http://bugs.java.com/bugdatabase/view_bug.do?bug_id=4508058), -you would need to supply Java's UTF-8 charset e.g.: -```scala -file.contentAsString(charset = Charset.forName("UTF-8")) // Default incorrect JDK behaviour for UTF-8 (see: JDK-4508058) -``` - -If you also wish to write BOMs while encoding, you would need to supply it as: -```scala -file.write("hello world")(charset = UnicodeCharset("UTF-8", writeByteOrderMarkers = true)) -``` - -### Java serialization utils -Some common utils to serialize/deserialize using Java's serialization util -```scala -case class Person(name: String, age: Int) -val person = new Person("Chris", 24) - -// Write -file.newOutputStream.buffered.asObjectOutputStream.serialize(obj).flush() - -// Read -val person2 = file.newInputStream.buffered.asObjectInputStream.readObject().asInstanceOf[Person] -assert(person == person2) -``` - -The above can be simply written as: -```scala -val person2: Person = file.writeSerialized(person).readDeserialized[Person] -assert(person == person2) -``` - -### Java interoperability -You can always access the Java I/O classes: -```scala -val file: File = tmp / "hello.txt" -val javaFile : java.io.File = file.toJava -val uri : java.net.URI = file.uri -val url : java.net.URL = file.url -val reader : java.io.BufferedReader = file.newBufferedReader -val outputstream : java.io.OutputStream = file.newOutputStream -val writer : java.io.BufferedWriter = file.newBufferedWriter -val inputstream : java.io.InputStream = file.newInputStream -val path : java.nio.file.Path = file.path -val fs : java.nio.file.FileSystem = file.fileSystem -val channel : java.nio.channel.FileChannel = file.newFileChannel -val ram : java.io.RandomAccessFile = file.newRandomAccess -val fr : java.io.FileReader = file.newFileReader -val fw : java.io.FileWriter = file.newFileWriter(append = true) -val printer : java.io.PrintWriter = file.newPrintWriter -``` -The library also adds some useful [implicits](http://pathikrit.github.io/better-files/latest/api/better/files/Implicits.html) to above classes e.g.: -```scala -file1.reader > file2.writer // pipes a reader to a writer -System.in > file2.out // pipes an inputstream to an outputstream -src.pipeTo(sink) // if you don't like symbols - -val bytes : Iterator[Byte] = inputstream.bytes -val bis : BufferedInputStream = inputstream.buffered -val bos : BufferedOutputStream = outputstream.buffered -val reader : InputStreamReader = inputstream.reader -val writer : OutputStreamWriter = outputstream.writer -val printer : PrintWriter = outputstream.printWriter -val br : BufferedReader = reader.buffered -val bw : BufferedWriter = writer.buffered -val mm : MappedByteBuffer = fileChannel.toMappedByteBuffer -val str : String = inputstream.asString //Read a string from an InputStream -``` -`better-files` also supports [certain conversions that are not supported out of the box by the JDK](https://stackoverflow.com/questions/62241/how-to-convert-a-reader-to-inputstream-and-a-writer-to-outputstream) - -[`tee`](http://stackoverflow.com/questions/7987395/) multiple outputstreams: -```scala -val s3 = s1 tee s2 -s3.printWriter.println(s"Hello world") // gets written to both s1 and s2 -``` - -### Globbing -No need to port [this](http://docs.oracle.com/javase/tutorial/essential/io/find.html) to Scala: -```scala -val dir = "src"/"test" -val matches: Iterator[File] = dir.glob("*.{java,scala}") -// above code is equivalent to: -dir.listRecursively.filter(f => f.extension == Some(".java") || f.extension == Some(".scala")) -``` - -You can even use more advanced regex syntax instead of [glob syntax](http://docs.oracle.com/javase/tutorial/essential/io/fileOps.html#glob): -```scala -val matches = dir.globRegex("^\\w*$".r) //equivalent to dir.glob("^\\w*$")(syntax = File.PathMatcherSyntax.regex) -``` - -By default, glob syntax in `better-files` is [different from](https://github.com/pathikrit/better-files/issues/114) -the default JDK glob behaviour since it always includes path. To use the default behaviour: -```scala -dir.glob("**/*.txt", includePath = false) // JDK default -//OR -dir.glob("*.txt", includePath = true) // better-files default -``` -You can also extend the `File.PathMatcherSyntax` to create your own matchers. - -For custom cases: -```scala -dir.collectChildren(_.isSymbolicLink) // collect all symlinks in a directory -``` -For simpler cases, you can always use `dir.list` or `dir.walk(maxDepth: Int)` - -### File system operations -Utilities to `ls`, `cp`, `rm`, `mv`, `ln`, `md5`, `touch`, `cat` etc: -```scala -file.touch() -file.delete() // unlike the Java API, also works on directories as expected (deletes children recursively) -file.clear() // If directory, deletes all children; if file clears contents -file.renameTo(newName: String) -file.moveTo(destination) -file.moveToDirectory(destination) -file.copyTo(destination) // unlike the default API, also works on directories (copies recursively) -file.copyToDirectory(destination) -file.linkTo(destination) // ln destination file -file.symbolicLinkTo(destination) // ln -s destination file -file.{checksum, md5, sha1, sha256, sha512, digest} // also works for directories -file.setOwner(user: String) // chown user file -file.setGroup(group: String) // chgrp group file -Seq(file1, file2) `>:` file3 // same as cat file1 file2 > file3 (must import import better.files.Dsl.SymbolicOperations) -Seq(file1, file2) >>: file3 // same as cat file1 file2 >> file3 (must import import better.files.Dsl.SymbolicOperations) -file.isReadLocked; file.isWriteLocked; file.isLocked -File.numberOfOpenFileDescriptors // number of open file descriptors -``` -You can also load resources from your classpath using `File.resource` or `File.copyResource`. - -### Temporary files -Utils to create temporary files: -```scala -File.newTemporaryDirectory() -File.newTemporaryFile() -``` -The above APIs allow optional specifications of `prefix`, `suffix` and `parentDir`. -These files are [not deleted automatically on exit by the JVM](http://stackoverflow.com/questions/16691437/when-are-java-temporary-files-deleted) (you have to set `deleteOnExit` which adds to `shutdownHook`). - -A cleaner alternative is to use self-deleting file contexts which deletes the file immediately when done: -```scala -for { - tempFile <- File.temporaryFile() -} doSomething(tempFile) // tempFile is auto deleted at the end of this block - even if an exception happens -``` - -OR equivalently: -```scala -File.usingTemporaryFile() {tempFile => - //do something -} // tempFile is auto deleted at the end of this block - even if an exception happens -``` - -You can make any files temporary (i.e. delete after use) by doing this: -```scala -val foo = File.home / "Downloads" / "foo.txt" - -for { - temp <- foo.toTemporary -} doSomething(temp) // foo is deleted at the end of this block - even if an exception happens -``` - -### UNIX DSL -All the above can also be expressed using [methods](http://pathikrit.github.io/better-files/latest/api/better/files/Dsl$.html) reminiscent of the command line: -```scala -import better.files._ -import better.files.Dsl._ // must import Dsl._ to bring in these utils - -pwd / cwd // current dir -cp(file1, file2) -mv(file1, file2) -rm(file) /*or*/ del(file) -ls(file) /*or*/ dir(file) -ln(file1, file2) // hard link -ln_s(file1, file2) // soft link -cat(file1) -cat(file1) >>: file -touch(file) -mkdir(file) -mkdirs(file) // mkdir -p -chown(owner, file) -chgrp(owner, file) -chmod_+(permission, files) // add permission -chmod_-(permission, files) // remove permission -md5(file); sha1(file); sha256(file); sha512(file) -unzip(zipFile)(targetDir) -zip(file*)(targetZipFile) -``` - -### File attributes -Query various file attributes e.g.: -```scala -file.name // simpler than java.io.File#getName -file.extension -file.contentType -file.lastModifiedTime // returns JSR-310 time -file.owner -file.group -file.isDirectory; file.isSymbolicLink; file.isRegularFile -file.isHidden -file.hide(); file.unhide() -file.isOwnerExecutable; file.isGroupReadable // etc. see file.permissions -file.size // for a directory, computes the directory size -file.posixAttributes; file.dosAttributes // see file.attributes -file.isEmpty // true if file has no content (or no children if directory) or does not exist -file.isParentOf; file.isChildOf; file.isSiblingOf; file.siblings -file("dos:system") = true // set custom meta-data for file (similar to Files.setAttribute) -``` -All the above APIs let you specify the [`LinkOption`](http://docs.oracle.com/javase/8/docs/api/java/nio/file/LinkOption.html) either directly: -```scala -file.isDirectory(LinkOption.NOFOLLOW_LINKS) -``` -Or using the [`File.LinkOptions`](http://pathikrit.github.io/better-files/latest/api/better/files/File$$LinkOptions$.html) helper: -```scala -file.isDirectory(File.LinkOptions.noFollow) -``` - -`chmod`: -```scala -import java.nio.file.attribute.PosixFilePermission -file.addPermission(PosixFilePermission.OWNER_EXECUTE) // chmod +X file -file.removePermission(PosixFilePermission.OWNER_WRITE) // chmod -w file -assert(file.permissionsAsString == "rw-r--r--") - -// The following are all equivalent: -assert(file.permissions contains PosixFilePermission.OWNER_EXECUTE) -assert(file.testPermission(PosixFilePermission.OWNER_EXECUTE)) -assert(file.isOwnerExecutable) -``` - -### File comparison -Use `==` to check for path-based equality and `===` for content-based equality: -```scala -file1 == file2 // equivalent to `file1.isSamePathAs(file2)` -file1 === file2 // equivalent to `file1.isSameContentAs(file2)` (works for regular-files and directories) -file1 != file2 // equivalent to `!file1.isSamePathAs(file2)` -file1 !== file2 // equivalent to `!file1.isSameContentAs(file2)` -``` -There are also various [`Ordering[File]` instances](http://pathikrit.github.io/better-files/latest/api/better/files/File$$Order$.html) included, e.g.: -```scala -val files = myDir.list.toSeq -files.sorted(File.Order.byName) -files.max(File.Order.bySize) -files.min(File.Order.byDepth) -files.max(File.Order.byModificationTime) -files.sorted(File.Order.byDirectoriesFirst) -``` - -### Zip APIs -You don't have to lookup on StackOverflow "[How to zip/unzip in Java/Scala?](http://stackoverflow.com/questions/9324933/)": -```scala -// Unzipping: -val zipFile: File = file"path/to/research.zip" -val research: File = zipFile.unzipTo(destination = home/"Documents"/"research") - -// Zipping: -val zipFile: File = directory.zipTo(destination = home/"Desktop"/"toEmail.zip") - -// Zipping in: -val zipFile = File("countries.zip").zipIn(file"usa.txt", file"russia.txt") - -// Zipping/Unzipping to temporary files/directories: -val someTempZipFile: File = directory.zip() -val someTempDir: File = zipFile.unzip() -assert(directory === someTempDir) - -// Gzip handling: -File("countries.gz").newInputStream.gzipped.lines.take(10).foreach(println) -``` - -### Lightweight ARM -Auto-close Java closeables: -```scala -for { - in <- file1.newInputStream.autoClosed - out <- file2.newOutputStream.autoClosed -} in.pipeTo(out) -// The input and output streams are auto-closed once out of scope -``` -`better-files` provides convenient managed versions of all the Java closeables e.g. instead of writing: -```scala -for { - reader <- file.newBufferedReader.autoClosed -} foo(reader) -``` -You can write: -```scala -for { - reader <- file.bufferedReader // returns ManagedResource[BufferedReader] -} foo(reader) - -// or simply: -file.bufferedReader.foreach(foo) -``` - -You can also define your own custom disposable resources e.g.: -```scala -trait Shutdownable { - def shutdown(): Unit = () -} - -object Shutdownable { - implicit val disposable: Disposable[Shutdownable] = Disposable(_.shutdown()) -} - -val s: Shutdownable = .... - -for { - instance <- new ManagedResource(s) -} doSomething(s) // s is disposed after this -``` - -### Scanner -Although [`java.util.Scanner`](http://docs.oracle.com/javase/8/docs/api/java/util/Scanner.html) has a feature-rich API, it only allows parsing primitives. -It is also [notoriously slow](https://www.cpe.ku.ac.th/~jim/java-io.html) since it uses regexes and does un-Scala things like returns nulls and throws exceptions. - -`better-files` provides a [faster](benchmarks#benchmarks), richer, safer, more idiomatic and compossible [Scala replacement](http://pathikrit.github.io/better-files/latest/api/better/files/Scanner.html) -that [does not use regexes](core/src/main/scala/better/files/Scanner.scala), allows peeking, accessing line numbers, returns `Option`s whenever possible and lets the user mixin custom parsers: -```scala -val data = t1 << s""" - | Hello World - | 1 true 2 3 -""".stripMargin -val scanner: Scanner = data.newScanner() -assert(scanner.next[String] == "Hello") -assert(scanner.lineNumber == 1) -assert(scanner.next[String] == "World") -assert(scanner.next[(Int, Boolean)] == (1, true)) -assert(scanner.tillEndOfLine() == " 2 3") -assert(!scanner.hasNext) -``` -If you are simply interested in tokens, you can use `file.tokens()` - -Writing your own custom scanners: -```scala -sealed trait Animal -case class Dog(name: String) extends Animal -case class Cat(name: String) extends Animal - -implicit val animalParser: Scannable[Animal] = Scannable {scanner => - val name = scanner.next[String] - if (name == "Garfield") Cat(name) else Dog(name) -} - -val scanner = file.newScanner() -println(scanner.next[Animal]) -``` - -The [shapeless-scanner](shapeless/src/main/scala/better/files/ShapelessScanner.scala) module lets you scan [`HList`s](https://github.com/milessabin/shapeless/blob/master/core/src/main/scala/shapeless/hlists.scala): -```scala -val in = Scanner(""" - 12 Bob True - 13 Mary False - 26 Rick True -""") - -import shapeless._ - -type Row = Int :: String :: Boolean :: HNil - -val out = Seq.fill(3)(in.next[Row]) -assert(out == Seq( - 12 :: "Bob" :: true :: HNil, - 13 :: "Mary" :: false :: HNil, - 26 :: "Rick" :: true :: HNil -)) -``` - -[and case-classes](https://meta.plasm.us/posts/2015/11/08/type-classes-and-generic-derivation/): - -```scala -case class Person(id: Int, name: String, isMale: Boolean) -val out2 = Seq.fill(3)(in.next[Person]) -``` - -Simple CSV reader: -```scala -val file = """ - 23,foo - 42,bar -""" -val csvScanner = file.newScanner(StringSpliiter.on(',')) -csvScanner.next[Int] //23 -csvScanner.next[String] //foo -``` - -### File Monitoring -Vanilla Java watchers: -```scala -import java.nio.file.{StandardWatchEventKinds => EventType} -val service: java.nio.file.WatchService = myDir.newWatchService -myDir.register(service, events = Seq(EventType.ENTRY_CREATE, EventType.ENTRY_DELETE)) -``` -The above APIs are [cumbersome to use](https://docs.oracle.com/javase/tutorial/essential/io/notification.html#process) (involves a lot of type-casting and null-checking), -are based on a blocking [polling-based model](http://docs.oracle.com/javase/8/docs/api/java/nio/file/WatchKey.html), -does not easily allow [recursive watching of directories](https://docs.oracle.com/javase/tutorial/displayCode.html?code=https://docs.oracle.com/javase/tutorial/essential/io/examples/WatchDir.java) -and nor does it easily allow [watching regular files](http://stackoverflow.com/questions/16251273/) without writing a lot of Java boilerplate. - -`better-files` abstracts all the above ugliness behind a [simple interface](core/src/main/scala/better/files/File.scala#1100): -```scala -val watcher = new FileMonitor(myDir, recursive = true) { - override def onCreate(file: File, count: Int) = println(s"$file got created") - override def onModify(file: File, count: Int) = println(s"$file got modified $count times") - override def onDelete(file: File, count: Int) = println(s"$file got deleted") -} -watcher.start() -``` -Sometimes, instead of overwriting each of the 3 methods above, it is more convenient to override the dispatcher itself: -```scala -import java.nio.file.{Path, StandardWatchEventKinds => EventType, WatchEvent} - -val watcher = new FileMonitor(myDir, recursive = true) { - override def onEvent(eventType: WatchEvent.Kind[Path], file: File, count: Int) = eventType match { - case EventType.ENTRY_CREATE => println(s"$file got created") - case EventType.ENTRY_MODIFY => println(s"$file got modified $count") - case EventType.ENTRY_DELETE => println(s"$file got deleted") - } -} -``` - -### Akka File Watcher -`better-files` also provides a powerful yet concise [reactive file watcher](akka/src/main/scala/better/files/FileWatcher.scala) -based on [Akka actors](http://doc.akka.io/docs/akka/snapshot/scala/actors.html) that supports dynamic dispatches: - ```scala -import akka.actor.{ActorRef, ActorSystem} -import better.files._, FileWatcher._ - -implicit val system = ActorSystem("mySystem") - -val watcher: ActorRef = (home/"Downloads").newWatcher(recursive = true) - -// register partial function for an event -watcher ! on(EventType.ENTRY_DELETE) { - case file if file.isDirectory => println(s"$file got deleted") -} - -// watch for multiple events -watcher ! when(events = EventType.ENTRY_CREATE, EventType.ENTRY_MODIFY) { - case (EventType.ENTRY_CREATE, file, count) => println(s"$file got created") - case (EventType.ENTRY_MODIFY, file, count) => println(s"$file got modified $count times") -} -``` diff --git a/scalalib/src/test/resource/better-files/akka/README.md b/scalalib/src/test/resource/better-files/akka/README.md deleted file mode 100644 index 391cec2e..00000000 --- a/scalalib/src/test/resource/better-files/akka/README.md +++ /dev/null @@ -1,394 +0,0 @@ -Reproduction of [this Java Advent article](http://www.javaadvent.com/2015/12/reactive-file-system-monitoring-using-akka-actors.html) -

File system monitoring using [Java NIO.2][nio2] -1. Common pitfalls of the default Java library -2. Design a simple thread-based file system monitor -3. Use the above to design a reactive file system monitor using the [actor][akka] [model][actorModel] - -**Note**: Although all the code samples here are in Scala, it can be rewritten in simple Java too.

You quickly realize that after the initial indexing of all the files, you need to also quickly reindex any new files (or directories) that got created or updated. A naive way would be to simply rescan the entire file system every few minutes; but that would be incredibly inefficient since most operating systems expose file system notification APIs that allow the application programmer to register callbacks for changes e.g. [ionotify][ionotify-wiki] in Linux, [FSEvenets][fsevents-wiki] in Mac and [FindFirstChangeNotification][FindFirstChangeNotification] in Windows. - -But now you are stuck dealing with OS-specific APIs! Thankfully, beginning Java SE 7, we have a platform independent abstraction for watching file system changes via the [WatchService API][javadoc-watchservice]. The WatchService API was developed as part of [Java NIO.2][nio2-wiki], under [JSR-51][jsr-51] and here is a "hello world" example of using it to watch a given [Path][javadoc-path]: - -```scala -import java.nio.file._ -import java.nio.file.StandardWatchEventKinds._ -import scala.collection.JavaConversions._ - -def watch(directory: Path): Unit = { - // First create the service - val service: WatchService = directory.getFileSystem.newWatchService() - - // Register the service to the path and also specify which events we want to be notified about - directory.register(service, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY) - - while (true) { - val key: WatchKey = service.take() // Wait for this key to be signalled - for {event <- key.pollEvents()} { - // event.context() is the path to the file that got changed - event.kind() match { - case ENTRY_CREATE => println(s"${event.context()} got created") - case ENTRY_MODIFY => println(s"${event.context()} got modified") - case ENTRY_DELETE => println(s"${event.context()} got deleted") - case _ => - // This can happen when OS discards or loses an event. - // See: http://docs.oracle.com/javase/8/docs/api/java/nio/file/StandardWatchEventKinds.html#OVERFLOW - println(s"Unknown event $event happened at ${event.context()}") - } - } - key.reset() // Do not forget to do this!! See: http://stackoverflow.com/questions/20180547/ - } -} -``` - -Although the above is a good first attempt, it lacks in several aspects: - -0. **Bad Design**: The above code looks unnatural and you probably had to [look it up on StackOverflow][so-down] to get it right. Can we do better? -2. **Bad Design**: The code does not do a very good job of handling errors. What happens when we encounter a file we could not open? -3. **Gotcha**: The Java API only allows us to watch the directory for changes to its direct children; it [does not recursively watch a directory][so-recursive-watching] for you. -4. **Gotcha**: The Java API [does not allow us to watch a single file][so-only-watch-dirs], only a directory. -5. **Gotcha**: Even if we resolve the aformentioned issues, the Java API [does not automatically start watching a new child file][so-autowatch] or directory created under the root. -6. **Bad Design**: The code as implemented above, exposes a blocking/polling, thread-based model. Can we use a better concurrency abstraction? - ------------ - - -Let's start with each of the above concerns. - -* **A better interface**: Here is what *my ideal* interface would look like: - -```scala -abstract class FileMonitor(root: Path) { - def start(): Unit - def onCreate(path: Path): Unit - def onModify(path: Path): Unit - def onDelete(path: Path): Unit - def stop(): Unit -} -``` - -That way, I can simply write the example code as: - -```scala -val watcher = new FileMonitor(myFile) { - override def onCreate(path: Path) = println(s"$path got created") - override def onModify(path: Path) = println(s"$path got modified") - override def onDelete(path: Path) = println(s"$path got deleted") -} -watcher.start() -``` - -Ok, let's try to adapt the first example using a Java `Thread` so that we can expose "my ideal interface": - -```scala -trait FileMonitor { // My ideal interface - val root: Path // starting file - def start(): Unit // start the monitor - def onCreate(path: Path) = {} // on-create callback - def onModify(path: Path) = {} // on-modify callback - def onDelete(path: Path) = {} // on-delete callback - def onUnknownEvent(event: WatchEvent[_]) = {} // handle lost/discarded events - def onException(e: Throwable) = {} // handle errors e.g. a read error - def stop(): Unit // stop the monitor -} -``` - -And here is a very basic thread-based implementation: - -```scala -class ThreadFileMonitor(val root: Path) extends Thread with FileMonitor { - setDaemon(true) // daemonize this thread - setUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler { - override def uncaughtException(thread: Thread, exception: Throwable) = onException(exception) - }) - - val service = root.getFileSystem.newWatchService() - - override def run() = Iterator.continually(service.take()).foreach(process) - - override def interrupt() = { - service.close() - super.interrupt() - } - - override def start() = { - watch(root) - super.start() - } - - protected[this] def watch(file: Path): Unit = { - file.register(service, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY) - } - - protected[this] def process(key: WatchKey) = { - key.pollEvents() foreach { - case event: WatchEvent[Path] => dispatch(event.kind(), event.context()) - case event => onUnknownEvent(event) - } - key.reset() - } - - def dispatch(eventType: WatchEvent.Kind[Path], file: Path): Unit = { - eventType match { - case ENTRY_CREATE => onCreate(file) - case ENTRY_MODIFY => onModify(file) - case ENTRY_DELETE => onDelete(file) - } - } -} -``` - -The above looks much cleaner! Now we can watch files to our heart's content without poring over the details of JavaDocs by simply implementing the `onCreate(path)`, `onModify(path)`, `onDelete(path)` etc. - -* **Exception handling**: This is already done above. `onException` gets called whenever we encounter an exception and the invoker can decide what to do next by implementing it. - -* **Recursive watching**: The Java API **does not allow recursive watching of directories**. We need to modify the `watch(file)` to recursively attach the watcher: - -```scala -def watch(file: Path, recursive: Boolean = true): Unit = { - if (Files.isDirectory(file)) { - file.register(service, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY) - // recursively call watch on children of this file - if (recursive) { - Files.list(file).iterator() foreach {f => watch(f, recursive)} - } - } -} -``` - -* **Watching regular files**: As mentioned before, the Java API **can only watch directories**. One hack we can do to watch single files is to set a watcher on its parent directory and only react if the event trigerred on the file itself. - -```scala -override def start() = { - if (Files.isDirectory(root)) { - watch(root, recursive = true) - } else { - watch(root.getParent, recursive = false) - } - super.start() -} -``` - -And, now in `process(key)`, we make sure we react to either a directory or that file only: - -```scala -def reactTo(target: Path) = Files.isDirectory(root) || (root == target) -``` - -And, we check before `dispatch` now: - -```scala -case event: WatchEvent[Path] => - val target = event.context() - if (reactTo(target)) { - dispatch(event.kind(), target) - } -``` - -* **Auto-watching new items**: The Java API, **does not auto-watch any new sub-files**. We can address this by attaching the watcher ourselves in `process(key)` when an `ENTRY_CREATE` event is fired: - -```scala -if (reactTo(target)) { - if (Files.isDirectory(root) && event.kind() == ENTRY_CREATE) { - watch(root.resolve(target)) - } - dispatch(event.kind(), target) -} -``` - -Putting it all together, we have our final [`FileMonitor.scala`][FileMonitor.scala]: - -```scala -class ThreadFileMonitor(val root: Path) extends Thread with FileMonitor { - setDaemon(true) // daemonize this thread - setUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler { - override def uncaughtException(thread: Thread, exception: Throwable) = onException(exception) - }) - - val service = root.getFileSystem.newWatchService() - - override def run() = Iterator.continually(service.take()).foreach(process) - - override def interrupt() = { - service.close() - super.interrupt() - } - - override def start() = { - if (Files.isDirectory(root)) { - watch(root, recursive = true) - } else { - watch(root.getParent, recursive = false) - } - super.start() - } - - protected[this] def watch(file: Path, recursive: Boolean = true): Unit = { - if (Files.isDirectory(file)) { - file.register(service, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY) - if (recursive) { - Files.list(file).iterator() foreach {f => watch(f, recursive)} - } - } - } - - private[this] def reactTo(target: Path) = Files.isDirectory(root) || (root == target) - - protected[this] def process(key: WatchKey) = { - key.pollEvents() foreach { - case event: WatchEvent[Path] => - val target = event.context() - if (reactTo(target)) { - if (Files.isDirectory(root) && event.kind() == ENTRY_CREATE) { - watch(root.resolve(target)) - } - dispatch(event.kind(), target) - } - case event => onUnknownEvent(event) - } - key.reset() - } - - def dispatch(eventType: WatchEvent.Kind[Path], file: Path): Unit = { - eventType match { - case ENTRY_CREATE => onCreate(file) - case ENTRY_MODIFY => onModify(file) - case ENTRY_DELETE => onDelete(file) - } - } -} -``` - ------ -Now, that we have addressed all the gotchas and distanced ourselves from the intricacies of the WatchService API, we are still tightly coupled to the thread-based API. -We will use the above class to expose a different concurrency model, namely, the [actor model][actorModel2] instead to design a reactive, dynamic and resilient file-system watcher using [Akka][akka-docs].

-"Jawn is for parsing jay-sawn." - -### Origin - -The term "jawn" comes from the Philadelphia area. It conveys about as -much information as "thing" does. I chose the name because I had moved -to Montreal so I was remembering Philly fondly. Also, there isn't a -better way to describe objects encoded in JSON than "things". Finally, -we get a catchy slogan. - -Jawn was designed to parse JSON into an AST as quickly as possible. - -[![Build Status](https://api.travis-ci.org/non/jawn.svg)](https://travis-ci.org/non/jawn) -[![Gitter](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/non/jawn?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) -[![Latest version](https://index.scala-lang.org/non/jawn/jawn-parser/latest.svg?color=orange)](https://index.scala-lang.org/non/jawn/jawn-parser) - -### Overview - -Jawn consists of four parts: - -1. A fast, generic JSON parser (`jawn-parser`) -2. A small, somewhat anemic AST (`jawn-ast`) -3. Support packages which parse to third-party ASTs -4. A few helpful utilities (`jawn-util`) - -Currently Jawn is competitive with the fastest Java JSON libraries -(GSON and Jackson) and in the author's benchmarks it often wins. It -seems to be faster than any other Scala parser that exists (as of July -2014). - -Given the plethora of really nice JSON libraries for Scala, the -expectation is that you're probably here for `jawn-parser` or a -support package. - -### Quick Start - -Jawn supports Scala 2.10, 2.11, and 2.12. - -Here's a `build.sbt` snippet that shows you how to depend on Jawn in -your own SBT project: - -```scala -resolvers += Resolver.sonatypeRepo("releases") - -// use this if you just want jawn's parser, and will implement your own facade -libraryDependencies += "org.spire-math" %% "jawn-parser" % "0.11.0" - -// use this if you want jawn's parser and also jawn's ast -libraryDependencies += "org.spire-math" %% "jawn-ast" % "0.11.0" -``` - -If you want to use Jawn's parser with another project's AST, see the -"Supporting external ASTs with Jawn" section. For example, with Spray -you would say: - -```scala -libraryDependencies += "org.spire-math" %% "jawn-spray" % "0.11.0" -``` - -There are a few reasons you might want to do this: - - * The library's built-in parser is significantly slower than Jawn's. - * Jawn supports more input types (`ByteBuffer`, `File`, etc.). - * You need asynchronous JSON parsing. - -(NOTE: previous to version 0.8.3 the support libraries would have been -named `"spray-support"` instead of `"jawn-spray"`.) - -### Dependencies - -*jawn-parser* has no dependencies other than Scala. - -*jawn-ast* depends on *jawn-parser* but nothing else. - -The various support projects (e.g. *jawn-argonaut*) depend on -the library they are supporting. - -### Parsing - -Jawn's parser is both fast and relatively featureful. Assuming you -want to get back an AST of type `J` and you have a `Facade[J]` -defined, you can use the following `parse` signatures: - -```scala -Parser.parseUnsafe[J](String) → J -Parser.parseFromString[J](String) → Try[J] -Parser.parsefromPath[J](String) → Try[J] -Parser.parseFromFile[J](File) → Try[J] -Parser.parseFromChannel[J](ReadableByteChannel) → Try[J] -Parser.parseFromByteBuffer[J](ByteBuffer) → Try[J] -``` - -Jawn also supports asynchronous parsing, which allows users to feed -the parser with data as it is available. There are three modes: - -* `SingleValue` waits to return a single `J` value once parsing is done. -* `UnwrapArray` if the top-level element is an array, return values as they become available. -* `ValueStream` parse one-or-more json values separated by whitespace. - -Here's an example: - -```scala -import jawn.ast -import jawn.AsyncParser -import jawn.ParseException - -val p = ast.JParser.async(mode = AsyncParser.UnwrapArray) - -def chunks: Stream[String] = ??? -def sink(j: ast.JValue): Unit = ??? - -def loop(st: Stream[String]): Either[ParseException, Unit] = - st match { - case s #:: tail => - p.absorb(s) match { - case Right(js) => - js.foreach(sink) - loop(tail) - case Left(e) => - Left(e) - } - case _ => - p.finish().right.map(_.foreach(sink)) - } - -loop(chunks) -``` - -You can also call `jawn.Parser.async[J]` to use async parsing with an -arbitrary data type (provided you also have an implicit `Facade[J]`). - -### Supporting external ASTs with Jawn - -Jawn currently supports six external ASTs directly: - -| AST | 2.10 | 2.11 | 2.12 | -|-----------|--------|--------|-------| -| Argonaut | 6.2 | 6.2 | 6.2 | -| Json4s | 3.5.2 | 3.5.2 | 3.5.2 | -| Play-json | 2.4.11 | 2.5.15 | 2.6.0 | -| Rojoma | 2.4.3 | 2.4.3 | 2.4.3 | -| Rojoma-v3 | 3.7.2 | 3.7.2 | 3.7.2 | -| Spray | 1.3.3 | 1.3.3 | 1.3.3 | - -Each of these subprojects provides a `Parser` object (an instance of -`SupportParser[J]`) that is parameterized on the given project's -AST (`J`). The following methods are available: - -```scala -Parser.parseUnsafe(String) → J -Parser.parseFromString(String) → Try[J] -Parser.parsefromPath(String) → Try[J] -Parser.parseFromFile(File) → Try[J] -Parser.parseFromChannel(ReadableByteChannel) → Try[J] -Parser.parseFromByteBuffer(ByteBuffer) → Try[J] -``` - -These methods parallel those provided by `jawn.Parser`. - -For the following snippets, `XYZ` is one of (`argonaut`, `json4s`, -`play`, `rojoma`, `rojoma-v3` or `spray`): - -This is how you would include the subproject in build.sbt: - -```scala -resolvers += Resolver.sonatypeRepo("releases") - -libraryDependencies += "org.spire-math" %% jawn-"XYZ" % "0.11.0" -``` - -This is an example of how you might use the parser into your code: - -```scala -import jawn.support.XYZ.Parser - -val myResult = Parser.parseFromString(myString) -``` - -### Do-It-Yourself Parsing - -Jawn supports building any JSON AST you need via type classes. You -benefit from Jawn's fast parser while still using your favorite Scala -JSON library. This mechanism is also what allows Jawn to provide -"support" for other libraries' ASTs. - -To include Jawn's parser in your project, add the following -snippet to your `build.sbt` file: - -```scala -resolvers += Resolver.sonatypeRepo("releases") - -libraryDependencies += "org.spire-math" %% "jawn-parser" % "0.11.0" -``` - -To support your AST of choice, you'll want to define a `Facade[J]` -instance, where the `J` type parameter represents the base of your JSON -AST. For example, here's a facade that supports Spray: - -```scala -import spray.json._ -object Spray extends SimpleFacade[JsValue] { - def jnull() = JsNull - def jfalse() = JsFalse - def jtrue() = JsTrue - def jnum(s: String) = JsNumber(s) - def jint(s: String) = JsNumber(s) - def jstring(s: String) = JsString(s) - def jarray(vs: List[JsValue]) = JsArray(vs) - def jobject(vs: Map[String, JsValue]) = JsObject(vs) -} -``` - -Most ASTs will be easy to define using the `SimpleFacade` or -`MutableFacade` traits. However, if an ASTs object or array instances -do more than just wrap a Scala collection, it may be necessary to -extend `Facade` directly. - -You can also look at the facades used by the support projects to help -you create your own. This could also be useful if you wanted to -use an older version of a supported library. - -### Using the AST - -#### Access - -For accessing atomic values, `JValue` supports two sets of -methods: *get-style* methods and *as-style* methods. - -The *get-style* methods return `Some(_)` when called on a compatible -JSON value (e.g. strings can return `Some[String]`, numbers can return -`Some[Double]`, etc.), and `None` otherwise: - -```scala -getBoolean → Option[Boolean] -getString → Option[String] -getLong → Option[Long] -getDouble → Option[Double] -getBigInt → Option[BigInt] -getBigDecimal → Option[BigDecimal] -``` - -In constrast, the *as-style* methods will either return an unwrapped -value (instead of returning `Some(_)`) or throw an exception (instead -of returning `None`): - -```scala -asBoolean → Boolean // or exception -asString → String // or exception -asLong → Long // or exception -asDouble → Double // or exception -asBigInt → BigInt // or exception -asBigDecimal → BigDecimal // or exception -``` - -To access elements of an array, call `get` with an `Int` position: - -```scala -get(i: Int) → JValue // returns JNull if index is illegal -``` - -To access elements of an object, call `get` with a `String` key: - -```scala -get(k: String) → JValue // returns JNull if key is not found -``` - -Both of these methods also return `JNull` if the value is not the -appropraite container. This allows the caller to chain lookups without -having to check that each level is correct: - -```scala -val v: JValue = ??? - -// returns JNull if a problem is encountered in structure of 'v'. -val t: JValue = v.get("novels").get(0).get("title") - -// if 'v' had the right structure and 't' is JString(s), then Some(s). -// otherwise, None. -val titleOrNone: Option[String] = t.getString - -// equivalent to titleOrNone.getOrElse(throw ...) -val titleOrDie: String = t.asString -``` - -#### Updating - -The atomic values (`JNum`, `JBoolean`, `JNum`, and `JString`) are -immutable. - -Objects are fully-mutable and can have items added, removed, or -changed: - -```scala -set(k: String, v: JValue) → Unit -remove(k: String) → Option[JValue] -``` - -If `set` is called on a non-object, an exception will be thrown. -If `remove` is called on a non-object, `None` will be returned. - -Arrays are semi-mutable. Their values can be changed, but their size -is fixed: - -```scala -set(i: Int, v: JValue) → Unit -``` - -If `set` is called on a non-array, or called with an illegal index, an -exception will be thrown. - -(A future version of Jawn may provide an array whose length can be -changed.) - -### Profiling - -Jawn uses [JMH](http://openjdk.java.net/projects/code-tools/jmh/) -along with the [sbt-jmh](https://github.com/ktoso/sbt-jmh) plugin. - -#### Running Benchmarks - -The benchmarks are located in the `benchmark` project. You can run the -benchmarks by typing `benchmark/run` from SBT. There are many -supported arguments, so here are a few examples: - -Run all benchmarks, with 10 warmups, 10 iterations, using 3 threads: - -`benchmark/run -wi 10 -i 10 -f1 -t3` - -Run just the `CountriesBench` test (5 warmups, 5 iterations, 1 thread): - -`benchmark/run -wi 5 -i 5 -f1 -t1 .*CountriesBench` - -#### Benchmark Issues - -Currently, the benchmarks are a bit fiddily. The most obvious symptom -is that if you compile the benchmarks, make changes, and compile -again, you may see errors like: - -``` -[error] (benchmark/jmh:generateJavaSources) java.lang.NoClassDefFoundError: jawn/benchmark/Bla25Bench -``` - -The fix here is to run `benchmark/clean` and try again. - -You will also see intermittent problems like: - -``` -[error] (benchmark/jmh:compile) java.lang.reflect.MalformedParameterizedTypeException -``` - -The solution here is easier (though frustrating): just try it -again. If you continue to have problems, consider cleaning the project -and trying again. - -(In the future I hope to make the benchmarking here a bit more -resilient. Suggestions and pull requests gladly welcome!) - -#### Files - -The benchmarks use files located in `benchmark/src/main/resources`. If -you want to test your own files (e.g. `mydata.json`), you would: - - * Copy the file to `benchmark/src/main/resources/mydata.json`. - * Add the following code to `JmhBenchmarks.scala`: - -```scala -class MyDataBench extends JmhBenchmarks("mydata.json") -``` - -Jawn has been tested with much larger files, e.g. 100M - 1G, but these -are obviously too large to ship with the project. - -With large files, it's usually easier to comment out most of the -benchmarking methods and only test one (or a few) methods. Some of the -slower JSON parsers get *much* slower for large files. - -#### Interpreting the results - -Remember that the benchmarking results you see will vary based on: - - * Hardware - * Java version - * JSON file size - * JSON file structure - * JSON data values - -I have tried to use each library in the most idiomatic and fastest way -possible (to parse the JSON into a simple AST). Pull requests to -update library versions and improve usage are very welcome. - -### Future Work - -More support libraries could be added. - -It's likely that some of Jawn's I/O could be optimized a bit more, and -also made more configurable. The heuristics around all-at-once loading -versus input chunking could definitely be improved. - -In cases where the user doesn't need fast lookups into JSON objects, -an even lighter AST could be used to improve parsing and rendering -speeds. - -Strategies to cache/intern field names of objects could pay big -dividends in some cases (this might require AST changes). - -If you have ideas for any of these (or other ideas) please feel free -to open an issue or pull request so we can talk about it. - -### Disclaimers - -Jawn only supports UTF-8 when parsing bytes. This might change in the -future, but for now that's the target case. You can always decode your -data to a string, and handle the character set decoding using Java's -standard tools. - -Jawn's AST is intended to be very lightweight and simple. It supports -simple access, and limited mutable updates. It intentionally lacks the -power and sophistication of many other JSON libraries. - -### Copyright and License - -All code is available to you under the MIT license, available at -http://opensource.org/licenses/mit-license.php. -
