Babel sources. It can be provided from WebJars dependency, minified 21 | or development version, 22 | * **`sourceDir`** - base path for JavaScript files you are going to translate, 23 | * **`targetDir`** - result path, note that all sub-directories from `sourceDir` will be preserved, 24 | * **`jsFiles`** - list of JavaScript files (static) from `sourceDir` to translate, 25 | * **`jsIncludes`** - list of JavaScript files (with simple masks `*`/`?`), 26 | * **`jsExcludes`** - list of exceptions for `jsIncludes`, 27 | * **`prefix`** - optional prefix applied for every translated file, 28 | * **`formatPresets`** - enable/disable presets formatting (default: _true_). Once disabled `presets` are required to be well formatted, 29 | * **`presets`** - presets for Babel execution (default: _es2015_), 30 | * **`plugins`** - plugins for Babel execution (default: _""_ (empty)) _NOTE: any custom plugins are required to be available in provided `babelSrc`_ 31 | 32 | ## Example 33 | ```xml 34 | 35 | com.jarslab.maven 36 | babel-maven-plugin 37 | 1.6 38 | 39 | 40 | js-transpile 41 | process-resources 42 | 43 | babel 44 | 45 | 46 | true 47 | 4 48 | ${project.basedir}/target/classes/assets/jslib/babel.min.js 49 | ${project.basedir}/target/classes/assets/ 50 | ${project.basedir}/target/classes/assets/ 51 | 52 | src/*.js 53 | 54 | trans- 55 | react,es2015 56 | 57 | 58 | 59 | 60 | ``` 61 | 62 | ## Changelog 63 | * **1.6**: Fix Presets handling 64 | * **1.5**: Add `plugins` option for Babel execution 65 | * **1.4**: Switch from deprecated Nashorn engine to GraalVM 66 | -------------------------------------------------------------------------------- /src/main/java/com/jarslab/maven/babel/plugin/transpiler/ParallelBabelTranspilerStrategy.java: -------------------------------------------------------------------------------- 1 | package com.jarslab.maven.babel.plugin.transpiler; 2 | 3 | import org.apache.maven.plugin.logging.Log; 4 | 5 | import java.util.Collection; 6 | import java.util.HashSet; 7 | import java.util.Set; 8 | import java.util.concurrent.CompletableFuture; 9 | import java.util.concurrent.ConcurrentLinkedQueue; 10 | import java.util.function.Supplier; 11 | import java.util.stream.Stream; 12 | 13 | import static java.lang.Runtime.getRuntime; 14 | import static java.lang.String.format; 15 | import static java.util.Objects.requireNonNull; 16 | 17 | public class ParallelBabelTranspilerStrategy implements BabelTranspilerStrategy 18 | { 19 | private final Log log; 20 | private final int threads; 21 | 22 | public ParallelBabelTranspilerStrategy(final Log log, 23 | final int threads) 24 | { 25 | this.log = requireNonNull(log); 26 | this.threads = getAvailableThreads(threads); 27 | } 28 | 29 | @Override 30 | public Stream execute(final Set transpilations) 31 | { 32 | final ConcurrentLinkedQueue queue = new ConcurrentLinkedQueue<>(transpilations); 33 | // Each thread's task is to create babel transpiler and perform as much transpilations as possible 34 | final Supplier> task = () -> { 35 | Thread.currentThread().setContextClassLoader(getClass().getClassLoader()); 36 | try (BabelTranspiler transpiler = new BabelTranspiler()) { 37 | final Set transpilationResults = new HashSet<>(); 38 | Transpilation currentTranspilation; 39 | while ((currentTranspilation = queue.poll()) != null) { 40 | if (log.isDebugEnabled()) { 41 | String name = Thread.currentThread().getName(); 42 | log.debug(format("[%s] transpiling %s", name, currentTranspilation.getSource())); 43 | } 44 | transpilationResults.add(transpiler.execute(currentTranspilation)); 45 | } 46 | return transpilationResults; 47 | } 48 | }; 49 | 50 | final Collection>> futures = new HashSet<>(); 51 | for (int i = 0; i < threads; i++) { 52 | futures.add(CompletableFuture.supplyAsync(task)); 53 | } 54 | 55 | return futures.stream() 56 | .map(CompletableFuture::join) 57 | .flatMap(Collection::stream); 58 | } 59 | 60 | private int getAvailableThreads(final int threads) 61 | { 62 | final int availableThreads = getRuntime().availableProcessors(); 63 | if (threads < 1) { 64 | log.warn(format("Invalid number of threads (%d).
