我目前在转会写的IntelliJ插件。我希望能够保存/恢复一组选项卡的不同标签的会话（与浏览器插件，像之间切换会话管理器或会话的好友）。

因此我需要三种基本类型的动作：

阅读打开的选项卡（其中文件和编辑用的？）
永久地存储信息的标签会话
选择会话并关闭所有其他打开的标签页

我看着可用的操作： IdeActions.java -似乎没有什么我寻找。但是，也许我期待在错误的地方。谁能告诉我，如果有什么我想实现是可能的，给我一些指点方向是正确的？

更新

我成功地创建了插件，它可以在Github上： http://alp82.github.com/idea-tabsession/

这是官方的插件库可供选择：选项卡会话。

简答

要阅读其标签是打开的，现在，使用EditorFactory和FileDocumentManager单身：

    Editor[] editors = EditorFactory.getInstance().getAllEditors();
    FileDocumentManager fileDocManager = FileDocumentManager.getInstance();
    for(Editor editor : editors) {
        VirtualFile vf = fileDocManager.getFile(editor.getDocument());
        String path = vf.getCanonicalPath();
        System.out.println("path = " + path);
    }

要打开的选项卡使用FileEditorManager单（ files被的规范路径的字符串数组）：

    FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
    for(String path : files) {
        System.out.println("path = " + path);
        VirtualFile vf = LocalFileSystem.getInstance().findFileByPath(path);
        fileEditorManager.openFile(vf, true, true);
    }

长的答案

先决条件

激活插件开发，Groovy和UI设计师插件
新建项目 - > IntelliJ IDEA的插件

结帐IDEA社区版源到任何文件夹：

 git clone git://git.jetbrains.org/idea/community.git idea

配置IDEA SDK，并创建插件

插件结构

创建了插件后，你需要编辑的plugin.xml坐落在META-INF文件夹中。修改id ， name和description 。

我们需要持续性的存储配置文件。创建mystorage.xml在文件中src文件夹。现在是时候创建所需的文件：

SessionComponent.java（与创建它Add Project Component向导来自动创建所需的XML设置）：

@State(
    name = "SessionComponent",
    storages = {
        @Storage(id = "default", file = StoragePathMacros.PROJECT_FILE),
        @Storage(id = "dir", file = StoragePathMacros.PROJECT_CONFIG_DIR + "/mystorage.xml", scheme = StorageScheme.DIRECTORY_BASED)
    }
)
public class SessionComponent implements ProjectComponent, PersistentStateComponent<SessionState> {

    Project project;
    SessionState sessionState;

    public SessionComponent(Project project) {
        this.project = project;
        sessionState = new SessionState();
    }

    public void initComponent() {
        // TODO: insert component initialization logic here
    }

    @Override
    public void loadState(SessionState sessionState) {
        System.out.println("load sessionState = " + sessionState);
        this.sessionState = sessionState;
    }

    public void projectOpened() {
        // called when project is opened
    }

    public void projectClosed() {
        // called when project is being closed
    }

    @Nullable
    @Override
    public SessionState getState() {
        System.out.println("save sessionState = " + sessionState);
        return sessionState;
    }

    public void disposeComponent() {
        // TODO: insert component disposal logic here
    }

    @NotNull
    public String getComponentName() {
        return "SessionComponent";
    }

    public int saveCurrentTabs() {
        Editor[] editors = getOpenEditors();
        FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
        VirtualFile[] selectedFiles = fileEditorManager.getSelectedFiles();

        FileDocumentManager fileDocManager = FileDocumentManager.getInstance();
        sessionState.files = new String[editors.length];
        int i = 0;
        for(Editor editor : editors) {
            VirtualFile vf = fileDocManager.getFile(editor.getDocument());
            String path = vf.getCanonicalPath();
            System.out.println("path = " + path);
            if(path.equals(selectedFiles[0].getCanonicalPath())) {
                sessionState.focusedFile = path;
            }
            sessionState.files[i] = path;
            i++;
        }

        return editors.length;
    }

    public int loadSession() {
        closeCurrentTabs();
        FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
        for(String path : sessionState.files) {
            System.out.println("path = " + path);
            VirtualFile vf = LocalFileSystem.getInstance().findFileByPath(path);
            fileEditorManager.openFile(vf, true, true);
        }

        return sessionState.files.length;
    }

    public void closeCurrentTabs() {
        Editor[] editors = getOpenEditors();
        FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
        FileDocumentManager fileDocManager = FileDocumentManager.getInstance();
        for(Editor editor : editors) {
            System.out.println("editor = " + editor);
            VirtualFile vf = fileDocManager.getFile(editor.getDocument());
            fileEditorManager.closeFile(vf);
        }
    }

    public void showMessage(String htmlText) {
        StatusBar statusBar = WindowManager.getInstance().getStatusBar(project);
        JBPopupFactory.getInstance()
            .createHtmlTextBalloonBuilder(htmlText, MessageType.INFO, null)
            .setFadeoutTime(7500)
            .createBalloon()
            .show(RelativePoint.getCenterOf(statusBar.getComponent()), Balloon.Position.atRight);
    }

    private Editor[] getOpenEditors() {
        return EditorFactory.getInstance().getAllEditors();
    }

}

我们还需要存储类：

public class SessionState {
    public String[] files = new String[0];
    public String focusedFile = "";

    public String toString() {
        String result = "";
        for (String file : files) {
            result += file + ", ";
        }
        result += "selected: " + focusedFile;
        return result;
    }
}

该组件类应该在plugin.xml这样一个条目：

<project-components>
  <component>
    <implementation-class>my.package.SessionComponent</implementation-class>
  </component>
</project-components>

该组件类提供了所有需要的功能，但永远不会被使用。因此，我们需要行动来执行加载和保存：

Save.java：

public class Save extends AnAction {

    public Save() {
        super();
    }

    public void actionPerformed(AnActionEvent event) {
        Project project = event.getData(PlatformDataKeys.PROJECT);
        SessionComponent sessionComponent = project.getComponent(SessionComponent.class);

        int tabCount = sessionComponent.saveCurrentTabs();
        String htmlText = "Saved " + String.valueOf(tabCount) + " tabs";
        sessionComponent.showMessage(htmlText);
    }

}

Load.java：

public class Load extends AnAction {

    public Load() {
        super();
    }

    public void actionPerformed(AnActionEvent event) {
        Project project = event.getData(PlatformDataKeys.PROJECT);
        SessionComponent sessionComponent = project.getComponent(SessionComponent.class);

        int tabCount = sessionComponent.loadSession();
        String htmlText = "Loaded " + String.valueOf(tabCount) + " tabs";
        sessionComponent.showMessage(htmlText);
    }

}

AAAND开拍！

我们需要的最后一件事是用户界面来选择这些动作。简单地说这在你plugin.xml ：

  <actions>
    <!-- Add your actions here -->
      <group id="MyPlugin.SampleMenu" text="_Sample Menu" description="Sample menu">
          <add-to-group group-id="MainMenu" anchor="last"  />
          <action id="MyPlugin.Save" class="my.package.Save" text="_Save" description="A test menu item" />
          <action id="MyPlugin.Load" class="my.package.Load" text="_Load" description="A test menu item" />
      </group>
  </actions>
