VSCode: Restart an extension automatically when its source has changed - visual-studio-code

I'm developing a VSCode extension. Is it possible to automatically have the extension reloaded when I change its source. Currently, I need to press Ctrl + SHift + F5.

I guess your extension is written in TS/javascript, so you can use fs.watch to watch your sources, and find a way to run the vscode command workbench.action.reloadWindow, which is
from sources of vscode, the function ReloadWindowAction.Run() or directly windowService.reloadWindow().
export class ReloadWindowAction extends Action {
static readonly ID = 'workbench.action.reloadWindow';
static LABEL = nls.localize('reloadWindow', "Reload Window");
constructor(
id: string,
label: string,
#IWindowService private windowService: IWindowService
) {
super(id, label);
}
run(): TPromise<boolean> {
return this.windowService.reloadWindow().then(() => true);
}
}
It might be a tiny extension that connect those functions.

how to add and select color for nodes/tree view items in explorer view in my vscode extension

I have added my own explorer view in my extension.
Here I added nodes/tree view items however I am not finding any way to customize and choose color my tree view items in explorer view.
Any idea how to achieve this?
There should be some way because when some file has error then its color is set to different compared to other open file.
[I assume this is your github issue: Not able to use FileDecorationProvider for tree view item.]
Here is my attempt at using a FileDecorationProvider for a custom TreeView. With the caveat that I am new to typescript and FileDecorations.
If you have seen Support proposed DecorationProvider api on custom views you know there are limitations on using a FileDecorationProvider for coloring TreeItem's - primarily that the decoration/coloration cannot be limited to your treeView - wherever that resourceUri apeears, like in the Explorer, your fileDecoration will be applied. That is very unfortunate but I don't believe there is any way to avoid that for now.
First, in your TreeItem class you will have to give whichever items you want decorated a resourceUri. Like this:
export class TreeTab extends vscode.TreeItem {
constructor( public readonly tab: vscode.Tab, public index: number = 0 ) {
super(tab.label, vscode.TreeItemCollapsibleState.None);
this.tab = tab;
if (tab.input instanceof vscode.TabInputText) {
this.resourceUri = tab.input.uri;
}
}
Ignore the specifics of the code for my extension, the point is:
this.resourceUri = <some vscode.Uri>;
Secondly, this is how I set up my FileDecoration class:
import {window, Tab, TabInputText, Uri, Disposable, Event, EventEmitter, FileDecoration, FileDecorationProvider, ThemeColor} from 'vscode';
export class TreeFileDecorationProvider implements FileDecorationProvider {
private disposables: Array<Disposable> = [];
private readonly _onDidChangeFileDecorations: EventEmitter<Uri | Uri[]> = new EventEmitter< Uri | Uri[]>();
readonly onDidChangeFileDecorations: Event<Uri | Uri[]> = this._onDidChangeFileDecorations.event;
constructor() {
this.disposables = [];
this.disposables.push(window.registerFileDecorationProvider(this));
}
async updateActiveEditor(activeTab: Tab): Promise<void> {
if (activeTab.input instanceof TabInputText)
this._onDidChangeFileDecorations.fire(activeTab.input.uri);
// filter to get only non-activeTabs
activeTab.group.tabs.map( tab => {
if (!tab.isActive && tab.input instanceof TabInputText)
this._onDidChangeFileDecorations.fire(tab.input.uri);
});
}
async provideFileDecoration(uri: Uri): Promise<FileDecoration | undefined> {
const activeEditor = window.activeTextEditor.document.uri;
if (uri.fsPath === activeEditor.fsPath) {
return {
badge: "⇐",
color: new ThemeColor("charts.red"),
// color: new vscode.ThemeColor("tab.activeBackground"),
// tooltip: ""
};
}
else return null; // to get rid of the custom fileDecoration
}
dispose() {
this.disposables.forEach((d) => d.dispose());
}
}
provideFileDecoration(uri: Uri) does the actual decorating. It finds only certain files and decorates them, and by returning null resets that previously decorated uri (as supplied by the uri argument).
updateActiveEditor() is an exported method that I call in other parts of the extension when I want to change a file decoration. So elsewhere I have this in another file:
import { TreeFileDecorationProvider } from './fileDecorator';
export class EditorManager {
public TreeItemDecorator: TreeFileDecorationProvider;
// and then on a listener that gets triggered when I need to make a change to some things including the FileDecoration for a uri
this.TreeItemDecorator.updateActiveEditor(activeTab);
this.TreeItemDecorator.updateActiveEditor(activeTab); that calls the updateActiveEditor method in the TreeFileDecorationProvider class which calls the this._onDidChangeFileDecorations.fire(<some uri>); method for uri's that need to have the decoration applied and also for uri's that need to have the decoration removed.
this._onDidChangeFileDecorations.fire(<some uri>); will call provideFileDecoration(uri: Uri) where the actual decoration will be applied or removed depending on some state of that uri.
I am sure there is a way to call onDidChangeFileDecorations() directly from another file in your project (if you don't need to do any pre-processing of the uri like I have to do. I just haven't figured out how to construct the argument for that function yet. Perhaps someone will help on that point.
You can see here:
color: new ThemeColor("charts.red"),
// color: new vscode.ThemeColor("tab.activeBackground"),
how a color is chosen - it must be some ThemeColor. The charts theme colors has a few basic colors that are handy to refer to. See theme color references, Charts therein.
The badge option can take up to 2 characters, but as you see I copied/pasted a unicode character for mine and that works.
As I mentioned my FileDecorationProvider is called from an eventListener, but you may not need that for your use case - if decorations do not have to added and removed based on user actions like in my case. So you may be able to call your FileDecorationProvider right from your extension.ts activate() like so:
import * as vscode from 'vscode';
import { TreeFileDecorationProvider } from './fileDecorator';
export async function activate(context: vscode.ExtensionContext) {
new TreeFileDecorationProvider();
}

Create new NetBeans "save as" module

My goal is simple - save the current HTML file in the NetBeans editor with one additional line at the top and bottom of the file, and with the extension of ".h".
This is my first attempt at a NetBeans module, but following some tutorials and research, I got as far as adding an entry to the popup menu when you right-click on an HTML file in the editor. It currently just shows a "Hello World" message:
The code to do that is here:
package ksmiller99.savehtmlasarduinoresource;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JOptionPane;
import org.openide.awt.ActionID;
import org.openide.awt.ActionReference;
import org.openide.awt.ActionRegistration;
import org.openide.util.NbBundle.Messages;
#ActionID(
category = "Edit",
id = "ksmiller99.savehtmlasarduinoresource.SaveHtmlAsArduinoResource"
)
#ActionRegistration(
displayName = "#CTL_SaveHtmlAsArduinoResource"
)
#ActionReference(path = "Editors/text/html/Popup")
#Messages("CTL_SaveHtmlAsArduinoResource=Save as Arduino Resource")
public final class SaveHtmlAsArduinoResource implements ActionListener {
#Override
public void actionPerformed(ActionEvent ev) {
//todo add a line to top and bottom of current file and save with .h extension
JOptionPane.showMessageDialog(null, "Hello Save As World");
}
}
How can I access the contents of the current editor? Would a different approach make more sense?
I'm using NetBeans 12.0, JDK 13, Windows 10.
Use the New Action wizard to create the source code for a Conditionally Enabled action, enabled when User Selects One Node.
In the 2nd wizard panel select File Type Context Menu and choose text/html as content type. If you want your action to appear only in the context menu you can disable Global Menu Item.
You should end up with code like this:
#ActionID(
category = "File",
id = "org.test.TestHtmlAction"
)
#ActionRegistration(
displayName = "#CTL_TestHtmlAction"
)
#ActionReference(path = "Loaders/text/html/Actions", position = 0)
#Messages("CTL_TestHtmlAction=TestHtmlAction")
public final class TestHtmlAction implements ActionListener
{
private final DataObject context;
private static final Logger LOGGER = Logger.getLogger(TestHtmlAction.class.getName());
public TestHtmlAction(DataObject context)
{
this.context = context;
}
#Override
public void actionPerformed(ActionEvent ev)
{
FileObject file = context.getPrimaryFile();
LOGGER.info("context=" + context.getName() + " file.getPath()=" + file.getPath());
}
}
The wizard creates a context aware action, which is enabled only when user selects a single HTML file node. The DataObject parameter gives you the context of the selected node, so you can retrieve the file path etc.

Why isn't Gtk Filechooser Button selecting any file in my flatpak build?

I have a file chooser button that triggers a change in the titlebar whenever a file is selected with it. And it seems to work fine in my non-flatpak build.
import gtk.Application : Application;
import gtk.ApplicationWindow : ApplicationWindow;
import gio.Application : GioApp = Application;
import gtkc.gtktypes : GApplicationFlags, FileChooserAction;
import gtk.FileChooserButton : FileChooserButton;
const string AppID = `org.github.flatfcbtest`;
int main(string[] args)
{
auto app = new App();
return app.run(args);
}
public class App : Application
{
public:
this(const string appID = AppID, const GApplicationFlags flags = GApplicationFlags.FLAGS_NONE)
{
super(appID, flags);
addOnActivate(delegate void(GioApp _) {
auto pw = new PrimaryWindow(this);
pw.showAll();
});
}
}
class PrimaryWindow : ApplicationWindow
{
this(Application app)
{
super(app);
setSizeRequest(500, 300);
auto fcb = new FileChooserButton(`Select file`, FileChooserAction.OPEN);
fcb.addOnFileSet(delegate void (FileChooserButton _) {
setTitle(`file set!`);
});
add(fcb);
}
}
(GtkD reference)
However in my flatpak builds, the file selected with the chooser button does not select anything and it keeps saying (None). However my titlebar is changes accordingly so I know that the signal was emitted by the file chooser button.
Here is my flatpak permissions list:
finish-args:
- --socket=fallback-x11
- --share=ipc
- --filesystem=host
- --device=all
- --socket=session-bus
What's causing this?
Typically if you're shipping a flatpak, you want to avoid --filesystem=host and just use GtkFileChooserNative instead. This class supports portals, allowing a user to select files the application does not have permission to access by itself.
This is a much better approach than giving the application full filesystem access. GtkFileChooserNative will still work in a non-flatpak application and you shouldn't notice any difference unless you're doing something fancy.
As for your question of why GtkFileChooser is not working with --filesystem=host however, I do not know.

fiddler shortcut for Browse in chrome

Are there any shortcut for browsing in chrome?Or if there any software could help set shortcuts by ourselves.
Pushing the Chrome entry in the browser dropdown will open Chrome instead of IE. Surprisingly, there's presently no public way of changing the default browser, although I'm guessing that Telerik will fix this eventually.
If this is a big problem for you, you could use the BindUIButton attribute on a FiddlerScript method to add a new toolbar button that does just that. Or you can create a QuickLink menu with the commands of your choice, e.g.
QuickLinkMenu("&Browse")
QuickLinkItem("&IE", "iexplore.exe")
QuickLinkItem("&Firefox", "firefox.exe")
QuickLinkItem("&Opera", "Opera.exe")
QuickLinkItem("&Chrome", "Chrome.exe")
public static function DoBrowsersMenu(sText: String, sAction: String)
{
var oS = FiddlerApplication.UI.GetSelectedSessions();
var sURL = String.Empty;
if (oS.Length > 0) { sURL = oS[0].fullUrl; }
System.Diagnostics.Process.Start(sAction, sURL);
}

Making Ctrl-C copy from whichever SourceViewer has focus in Eclipse plug-in

I successfully extended the PyDev editor in Eclipse with a side-by-side display, but I can't copy the contents of the extra SourceViewer that I added. I can select some text in the display, but when I press Ctrl+C, it always copies the main PyDev editor's selected text.
I found an article on key bindings in Eclipse editors, but the code there seems incomplete and a bit out-of-date. How can I configure the copy command to copy from whichever SourceViewer has focus?
The reason I want to do this is that I've written a tool for live coding in Python, and it would be much easier for users to submit bug reports if they could just copy the display and paste it into the bug description.
David Green's article was a good start, but it took a bit of digging to make it all work. I published a full example project on GitHub, and I'll post a couple of snippets here.
The TextViewerSupport class wires up a new action handler for each command you want to delegate to the extra text viewer. If you have multiple text viewers, just instantiate a TextViewerSupport object for each of them. It wires up everything in its constructor.
public TextViewerSupport(TextViewer textViewer) {
this.textViewer = textViewer;
StyledText textWidget = textViewer.getTextWidget();
textWidget.addFocusListener(this);
textWidget.addDisposeListener(this);
IWorkbenchWindow window = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow();
handlerService = (IHandlerService) window
.getService(IHandlerService.class);
if (textViewer.getTextWidget().isFocusControl()) {
activateContext();
}
}
The activateContext() method has a list of all the commands you want to delegate, and registers a new handler for each one. This was one of the changes from David's article; his ITextEditorActionDefinitionIds has been deprecated and replaced with IWorkbenchCommandConstants.
protected void activateContext() {
if (handlerActivations.isEmpty()) {
activateHandler(ITextOperationTarget.COPY,
IWorkbenchCommandConstants.EDIT_COPY);
}
}
// Add a single handler.
protected void activateHandler(int operation, String actionDefinitionId) {
StyledText textWidget = textViewer.getTextWidget();
IHandler actionHandler = createActionHandler(operation,
actionDefinitionId);
IHandlerActivation handlerActivation = handlerService.activateHandler(
actionDefinitionId, actionHandler,
new ActiveFocusControlExpression(textWidget));
handlerActivations.add(handlerActivation);
}
// Create a handler that delegates to the text viewer.
private IHandler createActionHandler(final int operation,
String actionDefinitionId) {
Action action = new Action() {
#Override
public void run() {
if (textViewer.canDoOperation(operation)) {
textViewer.doOperation(operation);
}
}
};
action.setActionDefinitionId(actionDefinitionId);
return new ActionHandler(action);
}
The ActiveFocusControlExpression gives the new handler a high enough priority that it will replace the standard handler, and it's almost identical to David's version. However, to get it to compile, I had to add extra dependencies to my plug-in manifest: I imported packages org.eclipse.core.expressions and org.eclipse.ui.texteditor.
