Use this guide to grab eclipse console output effortlessly. After reading it, you'll be able to grab eclipse console output successfully. But before we dive into it, let's start by answering this crucial question: What is the Console in Eclipse? The Console in Eclipse is what will enable you to view the output of the utilities invoked when building a project or the program's output when you run or debug running the application. Typically, you will follow these easy steps to view the output: Click Window > Preferences. Expand C/C++ and Build, then click Console. If you want to display information on the latest project only, use the "Always clear console before building check box" option. Optimize Each Line Of the Eclipse Output In your plugin, if you want to do something with each line of your eclipse output console, for example, write that line to a file or parse it before sending it to your custom eclipse view, you should create a class that implements IConsoleLineTracker, and you should add this extension point to your plugin.xml. [img_assist|nid=1032|title=|desc=The steps are explained well here...|link=none|align=none|width=256|height=192] Now, suppose your class implementing IConsoleLineTracker is this: public class LogTracker implements IConsoleLineTracker { private IConsole m_console; public void dispose() { } public void init(IConsole console) { m_console = console; } public void lineAppended(IRegion region) { try { String line = m_console.getDocument().get(region.getOffset(), region.getLength()); // DO SOMETHING WITH THAT LINE } catch (BadLocationException e) { WrCheck.logError(e); } } } Copy the console output in Eclipse The best method you can use to copy a console is to tell Eclipse to save console output to a file. To do this, you need to go to Run → Debug Configurations on the Eclipse menu. Once you Debug Configurations successfully, then navigate under the Standard Input and Output section, click on the checkbox next to File: and choose the name of the output file to use. Get the full Console in Eclipse Are you trying to get full console in Eclipse? The good news is it's possible to get it. All you need to do is go to Windows --> Preferences --> Run/Debug --> Console and then unchecking "Limit Console Output" which is ON by default. This works on STS any version too. This would help print complete console output. For a Mac, it is Eclipse > Preferences > Run/Debug > Console. View the console log in Eclipse If you want to view the console login to Eclipse: You need to go to Run -> Debug Configurations on the Eclipse menu. Then, under the "Standard Input and Output" section, Click on the checkbox next to "File:", and choose the name of the output file to use. If you check "Append" underneath, console output will be appended to the output file. How do I save data on the console? There will be times when you'll need to save data on the console. To do this, all you need to do is right-click > go to Save button, which is in the Console panel. It will allow you to save the logged messages to a file. In a situation where you have an object logged, then you can use the following steps: Right-click on the object on the console and click Store as a global variable. The output will be visible as "temp1.type in console". Copy (temp1), And paste it to your favorite text editor Install a detached console in Eclipse Want to attach the console to the main eclipse window? Follow these easy steps: Click Window->Perspective-> then go to Reset Perspective to detach it. EFCARDZ TREND REPORTS WEBINARS ZONES DZone > Performance Zone > Remotely Debugging an Eclipse Plugin Upgrade Eclipse Follow the instructions below to upgrade Eclipse: On the toolbar, navigate to Window > Install New Software. Click on Add and add the following URL for the latest build of Eclipse: https://download.eclipse.org/releases/latest. Alternatively, you could add the specific build of Eclipse you want from https://download.eclipse.org/releases/ such as: https://download.eclipse.org/releases/photon/ or go to https://download.eclipse.org/releases/2019-09/. Once the site is added to Eclipse, you can now proceed with the upgrade by navigating to Window > Help > Check for Updates. This basically goes through all the sites under Window > Preferences > Install/Update > Available Software Sites and gathers updated details from the ones that are selected. You should be able to see a pop-up listing the various plugins/tools that require an update. You have the option to select the ones that you need, or you can leave them as is. Then, click Next. Click Next after reviewing the details. You should now see the review license page. Click on the radio button "I accept ...." and click Finish. Remotely Debugging an Eclipse Plugin The Eclipse plugin can be debugged from inside the IDE while in the development phase, but once the plugin is installed in the IDE, we need to debug it remotely for bug resolution. In this quick tutorial, I'm going to explain how to debug an Eclipse plugin remotely. Plugin Project Let's suppose we have developed our simple Hello World plugin and installed it in our IDE. Now, to debug the plugin remotely, please follow the steps below. Step 1 Open the first instance of Eclipse IDE pointing to the workspace where your Hello World plugin project is located. Step 2 Navigate to the eclipse.ini file of your IDE. Here is a screenshot of the location of the file in macOS. Now add the following JVM arguments to the file: 1 -vmargs 2 -Xdebug 3 -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 Step 3 Now, open another instance of the Eclipse IDE (on macOS, use the command open -a -n Eclipse in the terminal). This instance will point to a workspace different from the one which contains the Hello World plugin project. Step 4 Now, in the workspace containing the Hello World plugin project, make the following remote debug configurations/; Navigate Run -> Debug Configurations -> Remote Java Application. Then hit the debug button. Also, do not forget to put break-points in the code of the Hello World plugin to be debugged. Step 5 In the other workspace (which does not contain the Hello World plugin), try to use the Hello World plugin and it will be remotely debugged in the other instance of Eclipse. Conclusion There are Eclipse-based IDEs that have a powerful feature to make ‘variants’ of the same projects. Use the to Build Configurations, which are a powerful feature in Eclipse. They will allow you to make ‘variants’ of a project. The project will share the common things, and you can simply tweak things one way or the other for example to produce a ‘release’ or a ‘debug’ binary of my application without duplicating the project.

With IntelliJ IDEA supporting a fully-functional integration with Maven, you can automate your entire building process. The result is that you can create a new Maven project as well as easily handle multi-module projects. Netbeans IDE on the other hand, simplifies the development of mobile applications as well as web and desktop applications using Java and HTML5. So imagine my surprise when some weeks ago, I saw a colleague fighting IntelliJ's Maven support. A dependency was not detected by IntelliJ's Maven support and to fix it, he had to remove the dependency from the POM, save it, add it back to the POM and save it again. Hmmm... somehow not quite optimal. This was the reason for me to take a look at IntelliJ's Maven support and compare some points with the support provided by NetBeans. Let’s look first at how IntelliJ IDEA can support an integration with Maven that is fully functional. This will assist you in automating the whole build. It doesn’t matter whether you wish to create a totally new Maven project, synchronize with an existing open project or add Maven support to existing IntelliJ IDEA projects. You can also manage projects that are multi-module. Creating New Maven Projects These are the steps I’d follow to create a new Maven Project. If you’re starting from scratch and there’s no project open currently in IntelliJ IDEA, go to the Welcome screen and click on New Project. Alternatively, you can select File and then create a new project for the main menu. Once you’ve created your new project, you must name it and if you require it, change its location. You’ll want to create the Git repository, so select the new project for placement under version control. Just be aware that you can do this at any time later in the build. Don’t forget to tick the box. Your project requires a language selection, so do that as well as add any other languages you may want via plugins. You do this by clicking “App>general add”. Under "build system", select Maven followed by specifying the project’s SDK. Or, you can go with the default or JDK. While it is not necessary, it’s a good idea to have a file with a basic sample code, so tick the “add sample code” box. Don’t neglect to specify Maven’s coordinates, which are included in the pom.xml file. You’ll find these in the advanced settings where a new project package is identified in the Groupid box and the project name is specified via the Artifactid box contents. Maven naming conventions follow Jav’s package name rules. This is in the format of a reversed domain name that you control e.g. org.apache.maven. While the naming conventions are not enforced, you’ll have a hard time getting names that don’t follow the rules in the Maven central repository, especially if it is a single word used for group IDs. When you’ve finished your selections, then click “create”. Handling Maven Projects If you open a Maven project in IntelliJ, IntelliJ still generates a default project folder (".idea") and file (".iml"). This means IntelliJ must always ensure that data in the POM is kept in sync with its proprietary structures. However, IntelliJ only handles one direction. Changes in the POM are recognized and the project settings are in sync most times. But if you change something in the project settings, these changes are not reflected in the POM. So, as my colleague experienced, you have to do it twice. Also, IntelliJ lists the "target" folder and ".idea" project settings folder in the logical project view, which is not useful most of the time. In IntelliJIDEA, the Maven project pom.xml file has a compiler included as well as the target Java version. There’s also a Maven tool window and any dependencies that are required to start work. Just bear in mind that the version of Java that is specified in the pom.xml file will, in all likelihood, override the "JDK for importer" option’s specification version. You can find this in the Maven settings. Configure Maven Settings To make things easier, configure your Maven settings before opening new projects. Configuring IntelliJ IDEA to display the Maven settings prior to opening an existing project that is being opened for the first time in IntelliJ IDEA is done at the application level. Once set, they’ll appear for any new project that you open. On the Welcome screen, “All settings” under the customize option. You can also access it from the main menu by selecting “file”, then “new project setup” followed by “preferences for new projects.” In the “preferences” dialog under settings, choose “build”, then “execution”. Under deployment, select Maven as your option under “build tools.” Now go to the Maven settings dialog and make the selection “Show settings dialog for new Maven projects”. You can then click OK and your changes will be saved for all future projects. What this does is, each time you open new projects, the Maven settings dialog is displayed by IntelliJ IDEA and you can then specify the local Maven repository’s location as well as a user settings file. In contrast, NetBeans uses the POM for pretty much everything. The Maven POM file defines the project, as shown below. If you change something in the project settings, it is directly stored in the POM. Only in rare cases, e.g., if you redefine actions, does NetBeans need to create a specific file. NetBeans only shows important information in the Projects window, as shown above. However, if you do want to see the Maven "target" folder, you can easily switch to the Files tab: Building Maven Projects When you build a Maven project in IntelliJ, with the default IDE commands, Maven is not used for the build process. The same goes for tests. If you are using different profiles for local development and your continuous integration server, you have to use Intellij's Maven integration tab to build and test your project with Maven. This is really ugly because you cannot use all the shortcuts that make life easier. NetBeans uses Maven for all that. You can simply press F11 or use the default toolbar button or menu item to build your applications with Maven. This same action works whether you are using Maven, a plain NetBeans Ant build script, or Gradle. It’s always the same consistent procedure. You can even change the Maven command that is used to build the project via F11. You are completely free to configure what you need: Executing Maven Goals Running Maven goals in IntelliJ displays a dialog with just two text fields and you have to type all the Maven parameters by hand. Hey man, it could be so much easier. Running a custom goal in NetBeans gives you a fantastic dialog with lots of possibilities. You can choose the profile, add properties, and even save everything to run it again later. This saves a lot of work. Conclusion There are many smaller issues that show that NetBeans has a smoother Maven integration than offered by IntelliJ. My impression is that IntelliJ's Maven support is just an extension to its default project management system since It still needs the default IntelliJ project folders and files. Meanwhile, NetBeans provides a much deeper and more complete integration. One more thing. I’m not an IntelliJ user so please forgive me if there is a mistake in my observations. I'm also not trying to start a new IDE war. What I want to do by means of this article is to get readers to think out of the box. If you are familiar with your IDE, that is great. If you are productive with your IDE, that is great. But if you think an IDE needs to be expensive in order to be a good product, you are totally wrong and should definitely give NetBeans a try.

Bringing Together Various Components There are situations in which it may be to the benefit of a programmer or other computer user to look at bringing together native components of a system with swing components. These are components that they have either created on their own accord or components that they have brought over from another service. Either way, combining the native components that already exist in a system with swing components is a great way to achieve some surprising results. You might want to think about giving this a try if you are thinking about how you can bring your talents up to date for use in the world as it is today. DJ Native Swing is a nice solution to embed native components (Web Browser, Flash Player, etc.). There was still a general issue that this library did not resolve though: the possibility to mix heavyweight and lightweight components with lightweight components on top, to change their Z-order or re-parent them. Fortunately, The release 0.9.3 offers interesting advances in this area. Using these features is as simple as changing some options before instantiating native components, in order to extend their behavior. You can try all the features (including the new options) with the Webstart Demo: http://djproject.sourceforge.net/ns/DJNativeSwingDemo.jnlp The Webstart demo is configured to work on Windows. It also works on Linux (GTK, x86/i386) where XULRunner is installed. Note that this demo is part of the release package. Run Tests on Every Component It is a good idea to run a demo of any components that you think you might want to put together. The reason for this is that you need to make sure those components will work for you as you anticipate that they will. This is far from a guarantee, and that is why you are called upon to pay careful attention to the things that you are running through these systems. It is entirely possible that you might find some errors that you made along the way when you are checking out the system to see where you went wrong. There is nothing bad about looking over something and realizing that you still have some room to grow and figure things out. As a matter of fact, this is a great way to grow as a person and as a programmer. You cannot begin to take steps in the right direction if you don't figure out where you can improve upon the decisions that you have made before. In my opinion, this gets us one step closer to proper native integration. What do you think? Have you got any comments or suggestions? Mixing Things Up for a New Creation Believe it or not, one of the best things that you can do to mix things up and keep your creations fresh is to look at how you can combine native components with the swing components that you bring into the system. It is a way for you to show the people who will ultimately use your creations that you are serious about making something that they stand to benefit from. If that is the kind of thing that you are into, then you need to give it a try right now. After all, there may be a tremendous number of people just waiting to see what you are all about and what you can offer to them. If you provide them with things to get excited about, then they will keep coming back for more. -Christopher

You've come to the right spot if you are trying to hack OpenJDK with NetBeans IDE. This article explains what OpenJDK with NetBeans is and how you can use NetBeans to create OpenJDK. But before we dive in, first things first: What are Hack OpenJDK and NetBeans IDE? Open Java Development Kit (JDK) is an open-source implementation of the Java Platform or Standard Edition. That means anyone can access the source code and GNU General Public license of the OpenJDK. You may also ask, "then what is Netbeans?" NetBeans is also an open-source integrated development environment for developing with Java, PHP, C++, and other programming languages. All THE applications are developed modules in Java. The OpenJDK repository contains a NetBeans project for all C/C++ parts of the OpenJDK, including Hotspot. So, since NetBeans is an Apache project, it is pretty easy to download and hack the code. You can run it on operating systems like Windows, Linux, and macOS. Remember, to use NetBeans for Java programming; you first need to install Java Development Kit (JDK). Can I use NetBeans with OpenJDK? Yes, you can. The latest NetBeans version of NetBeans is at NetBeans IDE 6.0 Beta 1. But keep this in mind, to hack OpenJDK, you'll need only the Java SE version. Which JDK is compatible with NetBeans? The JDK is compatible with JDK 8 features. That includes annotations, compact profiles, lambda expressions, and repeatable. When you use any of those constructs in your code, they will automatically highlight errors and allow you to fix syntax. Review, Hacking, and Develop OpenJDK. You follow these simple: Get OpenJDK, as follows: #hg clone http://hg.openjdk.java.net/jdk8/build jdk_trunk #cd jdk_trunk #sh get_source.sh #mkdir build #cd build #sh ../configure. After you’ve "configured", the step is complete, remember the value assigned to "Boot JDK" and then:#export IDE_ALT_BOOTDIR=jdk_path_found_by_configure #netbeansStart NetBeans IDE (with C++ support) and open projects from "common/nb_native". Just make sure that the project already contains configurations for Solaris, Linux, and macOS. You can do this by switching to the appropriate configuration and enjoying hacking OpenJDK. Next up, navigate inside your NetBeans project directory. Once there, you will find a directory called incubator-Netbeans. This directory contains sufficient NetBeans modules. Is OpenJDK with NetBeans IDE secure? As the emphasis increases, so does the need for security. Hence, you can easily create the Secure Directories. You can do this by choosing File > New Project (Ctrl-Shift-N), selecting Web Application from the Java Web category, and clicking Next. Regression testing verifies that system changes do not interfere with existing features or code structure. They are part of almost every test suite in software development lifecycles. It is common for developers to change or add a code section and unintentionally disrupt something that is working just fine. Visual regression testing functions on the same logic but confines it to the visual aspects of the software. It works by comparing two images and automating complicated scenarios, like when we cannot identify the elements in the DOM tree. However, visual regression can be used on any website. How Does Visual Regression Testing Work? During the first run, the visual comparison tool captures the snapshot called the base image. The subsequent run compares the base image if there is no difference test is passed, and if there is a difference, the test is considered as failed. Visual regression is also called visual comparison testing. In this tutorial, we will discuss automated visual regression using Playwright. Prerequisites for Visual Regression with Playwright Download and install NodeJS Download and install Visual Studio Code (Recommended) Install Playwright NPM module Install @playwright/test module Note Throughout this tutorial, we are using Playwright with JavaScript. Playwright comes with the default visual comparison tool, so there is no need to install additional packages. Create Simple Visual Comparison Tests Using Playwright In your tests folder, create a new JavaScript file example demo.spec.jspage.screenshot() function takes the screenshot, and expect in the @playwright/test module provides the assertion for matching the images that are .toMatchSnapshot(). Inside the newly created JavaScript file, create a new test that performs the visual comparison like below. Visual Comparison in Playwright to Ignore Minor Differences The above comparison technique matches the screenshot pixel by pixel, which means each pixel should match exactly. This behavior can be modified by passing the argument maxDiffPixels = . Example JavaScript const { test, expect } = require('@playwright/test'); test('Visual Comparison Test Demo', async ({ page }) => { await page.goto('https://playwright.dev'); expect(await page.screenshot()).toMatchSnapshot({ maxDiffPixels: 200 }); }); In the above example, we have specified the maxDiffPixels value as 200, which means the maximum pixel difference can be 200. Image Comparison in Playwright With Threshold Option Playwright toMatchSnapshot() accepts threshold, threshold ranges from 0 to 1, default value is 0.2. The threshold is tolerance of image differences. Example Code JavaScript const { test, expect } = require('@playwright/test'); test('Visual Comparison Test Demo', async ({ page }) => { await page.goto('https://playwright.dev'); expect(await page.screenshot()).toMatchSnapshot({threshold:0.5}); }); In the above code, the threshold is mentioned as 0.5. Playwright Visual Comparison Tips and Tricks In Playwright, we can pass the image file name; instead of default comparison, Playwright compares with the specified filename. Example expect(await page.screenshot()).toMatchSnapshot('home.png'); Playwright also allows us to compare element snapshots; we can take a snapshot of DOM elements and compare. Example expect(await page.locator('xpath=//*[@id="__docusaurus']).screenshot()).toMatchSnapshot(); Visual Regression With Playwright Using Percy Percy is a web-based tool for visual testing with a free tier, and it provides both manual and automation capability for visual comparison. Percy supports Playwright integration. Percy is now a part of Browserstack. If you already have a BrowserStack account, you can sign in with BrowserStack or sign up and create one. Using Percy With Playwright Step 1 – Install Percy modules using the following command. npm install --save-dev @percy/cli @percy/playwright Step 2 – Create a new JavaScript Playwright test file like below. JavaScript //demo.spec.ts const { chromium } = require('playwright'); const percySnapshot = require('@percy/playwright'); (async () => { const browser = await chromium.launch(); const page = await browser.newPage(); await page.goto('https://www.browserstack.com/', { waitUntil: 'networkidle' }); await percySnapshot(page, 'Example Site'); await browser.close(); })(); In the above example, we are navigating to https://www.browserstack.com/, and we are taking a snapshot using the percySnapshot() function. Setting Up Percy Step 1 – Login to Percy. If you don’t have an account, create one. Step 2 – Create a new project. Step 3 – Copy Percy token. Step 4 – In your Visual Studio Code Terminal, set the PERCY_TOKEN environment variable using the below commands: Powershell / Visual Studio Code Terminal $env:PERCY_TOKEN = "your_token"

Child controls on Windows Smartphone 7 are a big deal to a lot of people. The amount of data, information, and even adult materials that a child could have access to if on an unsecured phone is beyond what most parents are willing to risk. The Silverlight application makes it easier to view a complete list of the various child controls that one may decide to add to their Windows phone to keep it safe. After all, you never know when your child may get their hands on your phone and see things that you don't want them to have access to. ListBox Allows Me to Display Child Controls Usually, I am using ListBox control in my Windows Phone 7 Silverlight applications to display a scrollable list of child controls. ListBox offers UI virtualization, which means that UI is loading ListBox items on demand to increase the performance and reduce memory allocation. One of the main keys to that is in using VirtualizingStackPanel as ItemsPanel Template for ListBox control. Lately in one of my Windows Phone 7 projects I had to replace ListBox with ItemsControl, but ItemsControl does not offer UI virtualization for child items by default, so I had to add the same VirtualizingStackPanel to ItemsPanelTemplate element. Also I have modified the Template element to be able to add and access ScrollViewer for ItemsControl. View Everything in One Space VirtualizingStackPanel makes it easier to see everything on one screen so you can rest assured that nothing is slipping through the cracks. You don't want to leave any open security holes on your phone that your child may figure out a way to exploit. Unfortunately, many children are quite good at getting around security features that you have set up for them, and that is why you need to use VirtualizingStackPanel to review everything on your phone and make sure it is locked down. Now, you need to understand that this feature is not only useful for creating child security locks on your phone, but for many other purposes as well. You might want to breeze through and review other settings on your phone to ensure that you have it all set up optimally. After all, you don't want to waste time dealing with a phone that is not set up in the best way possible. What Type of Child Controls Are Available Via ListBox for Windows 7 Phones? Concerned parents everywhere will ask themselves what kind of controls they can expect to have over their Windows 7 phone when setting it up for their children to use. On the one hand, they know that their children will want to use their phones, and they don’t want to deny them the ability to delight in the technology that so many of the rest of us also enjoy every day. On the other hand, they are concerned parents who worry about what kind of things their children could be exposed to. The Windows 7 phone has numerous options that allow a parent to filter out things that they don’t necessarily want their children to see. A few of the popular controls that parents often set up for their children include: A block on inappropriate/adult websites A block on online gaming websites A timer that limits how long the child may use the phone These are all key features of the Windows 7 parental controls that are worth paying attention to. The reason is that children may be exposed to more from the outside world than you ever intended. Not only could they see inappropriate content, but they could get hooked on some of the online games that exist today. Those games are meant to be highly addictive by nature so that people will continue playing. However, this also poses a risk to children who may get exposed to too many stimuli from these games too early in their life. If that happens, then it may not be easy to peel away from those games. You certainly don’t want to take a risk like that with your child, and that is why you need to put a limit on the amount of time that they are able to view your screen on your phone. They need to take some time away from those screens in order to develop as people, and it is a lot better to use a program that will automatically cut them off from the online games that just want them to keep playing. How Do You Get Around Child Locks for Yourself? The other thing to keep in mind when using the software programs that are available to you for creating child locks on your phone is that you will need to circumvent those locks for yourself. You will still want access to the websites that you want to go to when your child doesn’t have your phone. Thus, you should make sure you are well-versed in how the Silverlight application works before you go to install it on your phone. Many people jump the gun too fast and try to get a program like this on their phone because they are so worried about their children being on the Internet and what it could mean for their safety. It is noble that people want to keep their children safe, but it is also responsible to want to make sure your phone is protected from the possibility of not having access to the full Internet that you may require at some point. You can, and should, install a backup password that you can use to get around any and all child locks that you put in place. Doing so will put you in the best position to get around the child lock and temporarily disable it while you use your phone as you normally would. The only thing to keep in mind is that you will need to put the child locks back on your phone once you are done using it and before you give it to your child. Once the locks are disabled, they won’t go back up unless you instruct them to do so via your phone. Many people have used child locks to keep their children from being exposed to material that they don’t want them to see too early in life. You may feel the same way, and it may be time for you to take direct action to ensure that your children are subjected to material that you wholeheartedly disagree with them seeing.
