我目前正在编写一个 IntelliJ 插件。我希望能够存储/恢复一组选项卡以在不同的选项卡会话之间切换（类似于Session Manager或Session Buddy等浏览器插件）。
因此，我基本上需要三种类型的动作：
我查看了可用的操作：IdeActions.java - 似乎没有我要搜索的内容。但也许我看错了地方。谁能告诉我我想要实现的目标是否可行，并给我一些正确方向的指示？
我成功创建了插件，它在 Github 上可用：http: //alp82.github.com/idea-tabsession/
它在官方插件存储库中可用：Tab Session。
这是关于拆分窗口的后续问题：检索和设置拆分窗口设置
我停止支持这个插件，因为 IDEA 已经支持这个功能。您可以轻松地保存和加载上下文，如下所示：https ://github.com/alp82/idea-tabsession#discontinued
该插件已准备就绪，可以在 IDEA -> 设置 -> 插件中下载。源代码位于：https ://github.com/alp82/idea-tabsession
要读取当前打开的选项卡，请使用EditorFactory和FileDocumentManagerSingletons：
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);
}
要打开选项卡，请使用FileEditorManager单例（files作为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);
}
将IDEA 社区版源签出到任何文件夹：
git clone git://git.jetbrains.org/idea/community.git idea
创建插件后，您需要编辑位于 META-INF 文件夹中的 plugin.xml。修改id,name和description.
我们需要一个用于持久存储的配置文件。mystorage.xml在您的文件夹中创建一个文件src。现在是时候创建所需的文件了：
SessionComponent.java（使用Add Project Component向导创建它以自动创建所需的 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;
}
}
组件类应该在您的 plugin.xml 中有一个条目，如下所示：
<project-components>
<component>
<implementation-class>my.package.SessionComponent</implementation-class>
</component>
</project-components>
组件类提供了所有需要的功能，但从未使用过。因此，我们需要执行加载和保存操作：
保存.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);
}
}
加载.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);
}
}
我们需要的最后一件事是选择这些操作的用户界面。简单地把它放在你的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>
The basic functionality is ready. I will add support for multiple sessions and some other neat stuff before deploying this plugin and releasing it to the open-source community. Link will be posted here, when it's online.
