# How to run a process

There are some preconditions if you want to start a process. This is an example where you download
an artifact, extract this artifact, provide command line arguments, start the process in an working
directory and, if done, clean up everything.

## provide every transition

This is an generic way to start an process.

```java

Transitions transitions = Transitions.from(
  InitTempDirectory.with(temp),

  Derive.given(TempDir.class)
    .state(ProcessWorkingDir.class)
    .with(Directories.deleteOnTearDown(
      TempDir.createDirectoryWith("workDir"),
      ProcessWorkingDir::of
    )),

  Derive.given(de.flapdoodle.embed.process.io.directories.TempDir.class)
    .state(DownloadCache.class)
    .deriveBy(tempDir -> new LocalDownloadCache(tempDir.value().resolve("archives")))
    .withTransitionLabel("setup DownloadCache"),

  Derive.given(de.flapdoodle.embed.process.io.directories.TempDir.class)
    .state(ExtractedFileSetStore.class)
    .deriveBy(tempDir -> new ContentHashExtractedFileSetStore(tempDir.value().resolve("fileSets")))
    .withTransitionLabel("setup ExtractedFileSetStore"),

  Start.to(Name.class).initializedWith(Name.of("phantomjs")).withTransitionLabel("create Name"),

  Start.to(SupportConfig.class).initializedWith(SupportConfig.generic()).withTransitionLabel("create default"),
  Start.to(ProcessConfig.class).initializedWith(ProcessConfig.defaults()).withTransitionLabel("create default"),
  Start.to(ProcessEnv.class).initializedWith(ProcessEnv.of(phantomJsEnv())).withTransitionLabel("create empty env"),

  Start.to(Version.class).initializedWith(Version.of("2.1.1")).withTransitionLabel("set version"),
  Derive.given(Name.class).state(ProcessOutput.class)
    .deriveBy(name -> ProcessOutput.namedConsole(name.value()))
    .withTransitionLabel("create named console"),

  Start.to(ProgressListener.class)
    .providedBy(StandardConsoleProgressListener::new)
    .withTransitionLabel("progressListener"),

  Start.to(ProcessArguments.class).initializedWith(ProcessArguments.of(Arrays.asList("--help")))
    .withTransitionLabel("create arguments"),

  Derive.given(Version.class).state(Distribution.class)
    .deriveBy(version -> Distribution.detectFor(CommonOS.list(), version))
    .withTransitionLabel("version + platform"),

  PackageOfDistribution.with(dist -> Package.builder()
    .archiveType(ArchiveType.TBZ2)
    .fileSet(FileSet.builder().addEntry(FileType.Executable, "phantomjs").build())
    .url(serverUrl + "phantomjs-" + dist.version().asInDownloadPath() + "-linux-x86_64.tar.bz2")
    .build()),

  DownloadPackage.withDefaults(),

  ExtractPackage.withDefaults()
    .withExtractedFileSetStore(StateID.of(ExtractedFileSetStore.class)),

  Executer.withDefaults()
);

TransitionWalker init = transitions.walker();

String dot = TransitionGraph.edgeGraphAsDot("sample", transitions);
recording.output("sample.dot", dot);
...


try (TransitionWalker.ReachedState<Archive> withArchive = init.initState(StateID.of(Archive.class))) {
  try (TransitionWalker.ReachedState<ExtractedFileSet> withFileSet = withArchive.initState(StateID.of(ExtractedFileSet.class))) {
    try (TransitionWalker.ReachedState<ExecutedProcess> started = withFileSet.initState(StateID.of(ExecutedProcess.class))) {
      assertThat(started.current().returnCode())
        .isEqualTo(0);
    }
  }
}

## use a custom class

This is one way to bundle common stuff and only specialize on the differences.

```java

Version.GenericVersion version = Version.of("2.1.1");

ProcessFactory processFactory = ProcessFactory.builder()
  .version(version)
  .persistentBaseDir(Start.to(PersistentDir.class)
    .initializedWith(PersistentDir.of(tempDir)))
  .name(Start.to(Name.class).initializedWith(Name.of("phantomjs")))
  .processArguments(Start.to(ProcessArguments.class).initializedWith(ProcessArguments.of(Arrays.asList("--help"))))
  .processEnv(Start.to(ProcessEnv.class).initializedWith(ProcessEnv.of(phantomJsEnv())))
  .packageInformation(dist -> Package.builder()
    .archiveType(ArchiveType.TBZ2)
    .fileSet(FileSet.builder().addEntry(FileType.Executable, "phantomjs").build())
    .url(serverUrl + "phantomjs-" + dist.version().asInDownloadPath() + "-linux-x86_64.tar.bz2")
    .build())
  .osList(CommonOS::list)
  .build();

TransitionWalker walker = processFactory.walker();
String dot = TransitionGraph.edgeGraphAsDot("process factory sample", processFactory.transitions());
recording.output("sample.dot", dot);

try (TransitionWalker.ReachedState<ExecutedProcess> started = walker.initState(StateID.of(ExecutedProcess.class))) {
  assertThat(started.current().returnCode())
    .isEqualTo(0);
