I try to figure out, how to update a virtual document with my own custom Provider, which I have opened in an editor. I neither understand the docu at https://code.visualstudio.com/api/extension-guides/virtual-documents#update-virtual-documents nor the example at https://github.com/microsoft/vscode-extension-samples/tree/master/contentprovider-sample
I tried to hack something like the following:
class MyProvider implements vscode.TextDocumentContentProvider {
public onDidChangeEmitter = new vscode.EventEmitter<vscode.Uri>();
onDidChange = this.onDidChangeEmitter.event;
public static instance: LocalChangesProvider | undefined;
public constructor() {
LocalChangesProvider.instance = this;
}
provideTextDocumentContent(uri: vscode.Uri) {
return someGlobal.text;
}
}
someGlobal.text = 'other text';
MyProvider.instance.onDidChangeEmitter.fire(myUriSchema);
But it seems I am missing something. I am kind of frustrated, that I am too stupid to simply notify vscode to update my own virtual document :/ Any help is appreciated :)
While working for a minimal full example I noticed, that the myUriSchema must match the title / path of the opened document, meaning:
const documentUriToUpdate = vscode.Uri.parse(myUriSchema + ':' + myTitle);
MyProvider.instance.onDidChangeEmitter.fire(documentUriToUpdate )
P.S.:
From a design perspective this instance-hack of mine definitely wins no price - just for PoC how it works :)

elemental2.dom.PushSubscription (v2.25, July 2019) has endpoint but not p256dh and auth keys, anyone know how to access these?
Any help greatly appreciated.
Phil.
You can do this, but note that this is not included in elemental2 because it is a Firefox-only method (actually looks like it is already supported in most browsers, although here said that it is Firefox-only).
{
PushSubscription subscription = …;
FirefoxPushSubscription firefoxPushSubscription = Js.cast(subscription);
}
#JsType(isNative = true, name = "PushSubscription", namespace = JsPackage.GLOBAL)
public static class FirefoxPushSubscription extends PushSubscription {
public native ArrayBuffer getKey(String name);

I am new to laravel. I am facing a very weird problem. I have a model comment which is related to User model in laravel.
The Relationships are defined as such
//App\User model
public function comments()
{
return $this->hasMany('App\comment');
}
And
//App\Comment model
public function User()
{
return $this->belongsTo('App\User');
}
now when i am fetching user and comment s using find and with it is returning data for all the users in the table. My code is like this: App\User::find(1)->with('comments')->get(); Can some one tell me what am doing wrong?
Try something like this
$comments=App\User::whereId(1)->comments->get();
This should load every comment associated with user with ID 1
//App\User model
public function comments() {
return $this->hasMany('App\comment','user_id','id');
}
//In your controller
use App\User;
$comment = User::where('id',2)->comments->get();
//I hope It's work for you!
Okay so I am making a custom feature for my OP-Prison server, one of the things that I need to do is get an integer from the players.yml file, check if it is >= one, if it is take away one, save it and then if it is still above one then they can repeat the action untill it's 0.
The issue comes with the fact that I have to restart the server for the file to change, and even when I do, it will only go down by one integer at a time, before having to reload it again.
GUI Creation code:
Main main = Main.getPlugin(Main.class);
#SuppressWarnings("unused")
private FileControl fc;
#SuppressWarnings("unused")
private FileControl playerfc;
public static String inventoryname = Utils.chat(Main.pl.getFileControl().getConfig().getString("Backpacks.White.InventoryName"));
public List<Player> WhiteOpened = new ArrayList<>();
public static Inventory whiteBackpack(Player player) {
Inventory whiteBackpack = Bukkit.createInventory(null, 27, (inventoryname));
UUID uuid = player.getUniqueId();
whiteBackpack.setItem(10,
new ItemCreator(Material.INK_SACK).setData(8)
.setDisplayname(Utils.chat("&fCommon Packages &8» &f&l" + Main.pl.getPlayerFile().getConfig().getInt("Users." + uuid + ".Packages.Common")))
.getItem());
return whiteBackpack;
}
Code for updating the config + item when the Commonpackage is clicked:
#EventHandler
public void whiteBackpackInteract(InventoryClickEvent event) {
Player player = (Player) event.getWhoClicked();
UUID uuid = player.getUniqueId();
ItemStack clicked = event.getCurrentItem();
String title = event.getInventory().getName();
if (title.equals(inventoryname)) {
// Making it so that the item cannot be moved
event.setCancelled(true);
if (clicked != null) {
if (event.getSlot() == 10) {
// Getting the user's common packages section in the config and checking if it is greater than or equal to 1.
if (Main.pl.getPlayerFile().getConfig().getInt("Users." + uuid + ".Packages.Common") >= 1) {
// Saving the user's common package section to 'currentCommon'
Integer currentCommon = Main.pl.getPlayerFile().getConfig().getInt("Users." + uuid + ".Packages.Common");
// Taking away one from 'currentCommon' and saving it to 'newCommon'
Integer newCommon = currentCommon - 1;
// Getting the 'players.yml' file
File file = new File(main.getDataFolder(), "players.yml");
FileConfiguration config = YamlConfiguration.loadConfiguration(file);
// Checking if the current common keys is greater than or equal to 1
if (currentCommon >= 1) {
try {
//Now, Here's where the error lies.
//Gets the player's common package count and sets it to the 'newCommon' count
config.set("Users." + uuid + ".Packages.Common", newCommon);
//Saves the players.yml file
config.save(file);
} catch (IOException e) {
e.printStackTrace();
}
// Updates the inventory they're currently in (Atleast it's meant to...)
player.updateInventory();
// Sends them a message (This is just for testing purposes, making sure it's working.)
player.sendMessage(Utils.chat("&8(&9Vexil&8) &fCommon Package"));
}
}
}
}
}
}
If there is any other code that you need, just ask I'll happily provide it for you.
Right now, you need to restart the server for it to save the data to the file. This should not happen, since you are calling the method config.save(file). The following is simply speculation, but it's the only cause that I think can easily explain what is going on.
In the object that is returned by getPlayerFile().getConfig(), there is likely a variable that stores a FileConfiguration object. That variable houses all the data from the players.yml file. In your whiteBackpackInteract() method, you load the data all over again. You then continue on to write to this NEW FileConfiguration variable, rather than the one that is stored in getPlayerfile().getConfig(). Since you then proceed to save to the file directly, the variables stored in the getPlayerfile().getConfig() is never told that you changed some values around. To fix this, you need to change the following:
config.set("Users." + uuid + ".Packages.Common", newCommon);
config.save(file);
to this:
Main.pl.getPlayerFile().getConfig().set("Users." + uuid + ".Packages.Common", newCommon);
Main.pl.getPlayerFile().getConfig().save(file);
and then delete this line of code:
FileConfiguration config = YamlConfiguration.loadConfiguration(file);
This should solve your problem entirely. If it does not, I would recommend not using your friend's custom config API and instead just use the ones that are built in. Using third party code that you don't properly understand can very often lead to problems such as this.
The following are not the bugs, but are suggestions to help improve your code:
You should be sure to put your comments ABOVE or to the RIGHT over the code they describe. People read from top to bottom, so the comments (before I made the suggested edit to your post) were all below the code they describe.
Typically, you want to try to make sure that if code doesn't need to be run, it isn't. Since the int newCommon is not used until inside that if statement, you should move it in there.
You are using Main.getPlugin();
Now while that doesn't seem like such a bad thing, your getting an unassigned variable, I have no idea how it is working but you're assigning Main to Main. There are 2 proper ways to actually get the main class.
The first, and generally best way, is to use dependency injection.
So basically,
public class Main extends JavaPlugin {
#Override
public void onEnable() {
BackpackListener listener new Backpacklistener(this);
getServer().getPluginManager().registerEvents(listener, this);
}
}
public class BackpackListener implements Listener {
private Main instance;
private BackpackUtil util;
public BackpackListener(Main instance) {
this.instance = instance;
util = new BackpackUtil();
}
#EventHandler
public void onClick(InventoryClickEvent event) {
//code
util.whiteBackpack(instance);
}
public class BackpackUtil {
public Inventory whiteBackpack(Main instance) {
FileConfiguration config = instance.getConfig();
//Do things
instance.saveConfig();
}
}
The next way you can do it is less optimal, and frowned upon, but still an easier option.
public class Main() {
public static Main instance;
#Override
public void onEnable() {
instance = this;
}
}
public class ConfigHelper() {
Main instance = Main.instance;
FileConfiguration config = instance.getConfig();
//Do things
instance.saveConfig();
}
It's good to get out of the habit of using the second method (It's called a singleton), because normally the main class will change, or have multiple instances, etc... but with Spigot there can only be one main instance and one thread.
I am trying to use the autocomplete addon in agile toolkit (I am still very much new to this, but it seems to be very well suited for my needs). Autocomplete Basic works, but when I use Plus and press the plus-button I get an error connected to no model set. In the Plus source the self-model should be used - but I don't understand how I should set the model of the autocomplete form.
This is the important part of the stack trace, I think:
Frontend_page_form: Form->setModel(Null)
Frontend_createquestions_form_question_id:
autocomplete\Form_Field_Plus->autocomplete{closure}(Object(Page))
This is my model:
class Model_QuestionInCollection extends Model_Table {
public $entity_code='questionincollection';
function init(){
parent::init();
$this->hasOne('Question')->display(array('form'=>'autocomplete/Plus'));
This is the code:
$form=$this->add('Form');
$form->setModel('QuestionInCollection');
--- EDIT
I ended up changing the model in autocomplete, and now it works, showing that something is wrong in the original "$self->model" - but of course it cannot be generalized. I did some extra changes (to make the new record show up in the autocomplete-field), so Autocomplete/Plus now is like this:
<?php
namespace autocomplete;
class Form_Field_Plus extends Form_Field_Basic
{
function init()
{
parent::init();
$self = $this;
$f = $this->other_field;
// Add buttonset to name field
$bs = $f->afterField()->add('ButtonSet');
// Add button - open dialog for adding new element
$bs->add('Button')
->set('+')
->add('VirtualPage')
->bindEvent('Add New Record', 'click')
->set(function($page)use($self) {
$model=$this->add('Model_Question');
$form = $page->add('Form');
$form->setModel($model); //Was: $self->model
//Would be nice if it worked...: $form->getElement($model->title_field)->set($self->other_field->js()->val());
if ($form->isSubmitted()) {
$form->update();
$js = array();
$js[] = $self->js()->val($form->model[$model->id_field]);
$js[] = $self->other_field->js()->val($form->model[$model->title_field]);
$form->js(null, $js)->univ()->closeDialog()->execute();
}
});
}
}
Here is an example on using autocomplete: http://codepad.demo.agiletech.ie/interactive-views/autocomplete
You can manually create a form and link the field with Model.
If that works fine, you can move on to trying and get your own example working. It seems OK, and should work in theory.
Some I do quite a lot of is read integers from AppSettings. What's the best way to do this?
Rather than do this every time:
int page_size;
if (int.TryParse( ConfigurationManager.AppSettings["PAGE_SIZE"], out page_size){
}
I'm thinking a method in my Helpers class like this:
int GetSettingInt(string key) {
int i;
return int.TryParse(ConfigurationManager.AppSettings[key], out i) ? i : -1;
}
but this is just to save some keystrokes.
Ideally, I'd love to put them all into some kind of structure that I could use intellisense with so I don't end up with run-time errors, but I don't know how I'd approach this... or if this is even possible.
What's a best practices way of getting and reading integers from the AppSettings section of the Web.Config?
ONE MORE THING...
wouldn't it be a good idea to set this as readonly?
readonly int pageSize = Helpers.GetSettingInt("PAGE_SIZE") doesn't seem to work.
I've found an answer to my problem. It involves extra work at first, but in the end, it will reduce errors.
It is found at Scott Allen's blog OdeToCode and here's my implementation:
Create a static class called Config
public static class Config {
public static int PageSize {
get { return int.Parse(ConfigurationManager.AppSettings["PAGE_SIZE"]); }
}
public static int HighlightedProductId {
get {
return int.Parse(ConfigurationManager.AppSettings["HIGHLIGHT_PID"]);
}
}
}
Advantage of doing this are three-fold:
Intellisense
One breakpoint (DRY)
Since I only am writing the Config String ONCE, I do a regular int.Parse.
If someone changes the AppSetting Key, it will break, but I can handle that, as those values aren't changed and the performance is better than a TryParse and it can be fixed in one location.
The solution is so simple... I don't know why I didn't think of it before. Call the values like so:
Config.PageSize
Config.HighlightedProductId
Yay!
I know that this question was asked many years ago, but maybe this answer could be useful for someone. Currently, if you're already receiving an IConfiguration reference in your class constructor, the best way to do it is using GetValue<int>("appsettings-key-goes-here"):
public class MyClass
{
private readonly IConfiguration _configuration;
public MyClass(IConfiguration configuration)
{
_configuration = configuration;
}
public void MyMethod()
{
int value = _configuration.GetValue<int>("appsettings-key-goes-here");
}
}
Take a look at T4Config. I will generate an interface and concrete implementation of your appsettings and connectionstringsections of you web/app config using Lazyloading of the values in the proper data types. It uses a simple T4 template to auto generate things for you.
To avoid creating a bicycle class you could use the following:
System.Configuration.Abstractions.AppSettings.AppSetting<int>("intKey");
