[ANNOUNCE] Apache NetBeans (incubating) 11.0 Released

The Apache NetBeans team is proud to announce the release of Apache NetBeans (incubating) 11.0.

Apache NetBeans (incubating) 11.0 constitutes all clusters in the Apache NetBeans Git repo, which together provide the NetBeans Platform (i.e., the underlying application framework), as well as all the modules that provide the Java SE, Java EE, PHP, JavaScript and Groovy features of Apache NetBeans.

In short, Apache NetBeans (incubating) 11.0 is a full IDE for Java SE, Java EE, PHP and JavaScript development with some Groovy language support.

Restructuring of Project Templates in Apache NetBeans

There's been lots of discussion in the Apache NetBeans community about how best to express the fact that Apache Maven and Apache Gradle are more modern choices to be aware of than Apache Ant, while at the same time not implying that there's anything wrong with using Apache Ant.

Here's what we seem to have reached consensus around, i.e., move all Ant-based project templates into a separate Ant-specific folder, while putting the other two build systems higher and therefore more prominently in the list:

With the above, someone is less likely to simply go to the no-longer-existing Java category and then end up with an Ant-based project, without thinking about it. By default, the user of Apache NetBeans is now encouraged to consider Apache Maven and Apache Gradle first. The old Ant-related categories are still there, so as not to confuse anyone completely, just structured within a lower ranked "Java with Ant" category. The above also solves the discussion re "Java EE", i.e., here the idea, from discussions, is to name the category "Java Enterprise".

At startup, all categories are closed, i.e., none is more prominent initially than any other.

An objection one could have is that, if you're a complete Java newbie, you won't know what Maven, Gradle, or Ant are. Well, that has always been the case and NetBeans has artificially hidden that choice by having a category simply named "Java", which then resulted in everyone ending up with Ant-based projects. To turn that around and have a category simply named "Java" that results in Maven-based projects is probably not right either, i.e., a careful balance needs to be struck.

Hoping that all factions in this lengthy discussion are relatively satisfied with this approach. :-)

Enterprise Cluster Integrated into Apache NetBeans

Hurray, the 'enterprise' cluster, constituting all the modules in Apache NetBeans GitHub that provide features for Java/Jakarta EE development, provided in the 2nd Oracle donation of NetBeans to Apache, has been integrated into the daily builds.

Now, for the first time, out of the box, you'll have the support that was part of NetBeans IDE 8.2 for Java EE development directly available in Apache NetBeans, that is, without you needing to install any plugins.

However, aside from the point that this means we do not yet have Java EE 8 support, since 8.2 did not (could not, because of being released some time prior to Java EE 8) have support for Java EE 8, another question now presents itself—whether we really want to have two categories in the New Project dialog, one named "Java EE" and the other named "Java Web", as shown below, with the former containing project types relating to EJBs and EARs, which are not (should not) be very current anymore, as shown below in the screenshots.

My suggestion would be to either relabel the above to "Modern Java EE" and "Vintage Java EE". (I like the word "Vintage", which I've learned about from JUnit, i.e., that's how they refer to JUnit 4.) Once there is Java EE 8 support, we could use the name "Jakarta" instead of "Modern Java EE". Or, maybe the EJB and EAR support should simply be removed?

Junit 5, Apache Ant, and Apache NetBeans

Junit 5 is, architecturally, so different to previous versions, that it should really be called Jupiter, instead. However, this is not a problem when you're using Maven, since Maven resolves all transitive dependencies for you, and is supported in that way from Apache NetBeans 10 onwards. Not so with Apache Ant, of course, where you need to set each and every JAR you need on a classpath of one form or another.

That is not a pretty picture in the end, when compared to JUnit 4, where you had just that JAR, plus Hamcrest. With JUnit 5, you need, in addition to junit-jupiter-api, junit-jupiter-params, and junit-jupiter-engine, to also declare the transitive dependency apiguardian-api, while in the case of Apache Ant, you need to deal with the JUnitLauncher, if you want to make use of the new junitlauncher Ant task, in addition to four other JARs, which need to be on Ant's classpath, as explained here.

An alternative approach is to use org.junit.platform.console.ConsoleLauncher, as shown here, which looks like this in my build.xml, i.e., it is named test, so that it will run automatically at the end of the test run when the Test Project action is invoked:

<target name="test" depends="compile-test,-pre-test-run">
    <java dir="${work.dir}" 
          classpath="${run.test.classpath}"  
          classname="org.junit.platform.console.ConsoleLauncher">
        <arg value="--scan-classpath"/>
        <arg line="--reports-dir build/test/results"/>
    </java>
    <junitreport todir="build/test/results">
        <fileset dir="build/test/results">
            <include name="TEST-*.xml"/>
        </fileset>
        <report format="frames" todir="build/test/results/html"/>
    </junitreport>
</target>

The above means that the JUnit tasks set by default in the build-impl.xml file will simply fail silently, since I don't have JUnit 4 on my classpath. At the end of the process, the above will be run, org.junit.platform.console.ConsoleLauncher will be found on my classpath, and then the JUnit 5 tests will be run.

What is the advantage of the above over using JUnitLauncher? Well, JUnitLauncher has requirements relating to Ant's path, which has advantages too, of course, i.e., simply set everything up once (which can also be done inside Apache NetBeans, in the Ant tab in the Options window). But, for right now, I'd prefer to work with just one path, i.e., the application's path.

Another downside is that, so far, the above solution doesn't integrate with the Test Results window, though it does produce some nice reports via the junitreport task above, in the build folder.

The key problem seems to me to be that the JUnit Ant task no longer exists in JUnit 5, which was for Ant-based projects the basis of the integration with the Test Results window in Apache NetBeans. If the JUnit task could continue to be used, in whatever way, that would solve a lot of the problems, though the question of the many JARs needed on the classpath would remain. Maybe library providers should reach out to tools providers when putting these kinds of new solutions together, since the only reason that JUnit 5 now works with Maven in Apache NetBeans is that Surefire is used, i.e., in the case of Maven the completely new approach JUnit has taken can simply be avoided there. Here is some relevant discussion in Apache NetBeans GitHub, and the Launcher API looks interesting.

Probably the best solution for Ant users in Apache NetBeans would be to be able to continue to use JUnit 4, rather than JUnit 5, since the latter is a total nightmare to set up in the context of Ant, as described above. In the world of JUnit, "vintage" is the cool name they have for "legacy", and if you're using Ant at all, you're probably best described as "vintage" and hence only having support for JUnit 4 is not a big deal for you. However, not sure at all how that would work, we'd need to investigate how/if when JUnit tests are added to Maven projects, JUnit 5 tests and dependencies would be set, while when adding JUnit tests to Ant projects JUnit 4 tests and dependencies would be set.

Master Your Scripting Skills with the New Tutorial!

Enhanced scripting tutorial has just become part of Apache NetBeans documentation. It contains various examples showing how to communicate from Java with JavaScript, Python and other languages. The following topics are covered:

While the primary use-case for this enhanced scripting API is to simplify usage of scripting languages in NetBeans based applications, the API itself is standalone and can be used outside of NetBeans in any project. We are working on making it available in the Maven central repository.

PHP 7.3 Support

Hi all. Today, we will briefly show you about PHP7.3 support which will be available in the next NetBeans version i.e. NetBeans 10.

First of all, I strongly hope that new features are tested by PHP users before NetBeans 10 is released because there should be bugs. Definitely, need your help! If you are interested in them, just test them. You can download a dev version here.

PHP 7.3 Support

To enable it, you have to set PHP 7.3 as the PHP version of your PHP project.

Nb10-php7.3-support-project-properties.png

NetBeans provides support for the new three syntaxes.

Allow a trailing comma in function calls

Nb10-php73-trailing-comma-in-function-calls.png

list() Referenct Assignment

Nb10-php73-list-reference-assignment.png

Flexible Heredoc and Nowdoc Syntaxes

Nb10-php73-flexible-heredoc-and-nowdoc-syntaxes.png

Note: We won't provide support for the old syntax any longer. i.e. NetBeans treats the following code as an error.

$heredoc = <<< END
END{$variable}
END;

PHP 7.1, 7.2 and more PHP features

The other PHP features for NetBeans 10 are here. We have also implemented PHP7.1, 7.2, new hints, new code foldings and more.

That's all for today. As always, please test it. You can download a development version from Jenkins Build. If you find some issues or enhancements, please report them to JIRA with your exact steps to reproduce them. (Components: php - Editor). Thanks.

Wednesday September 26, 2018

PHPStan Support

Hi all. Today, we will show you about PHPStan integration which will be available in the next NetBeans version i.e. NetBeans 10 as a new code analysis feature. If you have already used other code analysis features(e.g. Code Sniffer), you should be able to use this with similar way soon.

Options

First of all, let's set the Options (Tools > Options > PHP > Code Analysis > PHPStan). You can set a script path, a configuration file path and a level. At least you have to set the PHPStan script path to "PHPStan". If you don't set "Configuration" path, the configuration file of project root directory would be used.

Nb10-php-phpstan-support-options.png

Inspect project/directory/file

Then, let's inspect a project/direcoty/file using PHPStan. Please click "Source > Inspect...". The inspect dialog is shown.

Nb10-php-phpstan-support-inspect-dialog.png

Please choose "Scope" which you would like to inspect and PHPStan as "Configuration". The files are inspected when you click the "inspect" button. Finally, The results are shown in the inspector window after the inspection is done.

Nb10-php-phpstan-support-results.png

That's all for today. As always, please test it. You can download a development version from Jenkins Build. If you find some issues or enhancements, please report them to JIRA (Components: php - Code). Thanks.

Apache NetBeans Guest Blog: Edward M. Kagan

I'm a big fan of NetBeans, and a team-lead of 2pm.tech crew, a group of independent developers from Russia. For about the last five years, we have been using NetBeans in all of our projects, from "hardcore C embedded systems" to "Grails web-apps", and as a result we've also been hacking NetBeans a little.

As of 2018, there are now 11 developers in the team. Currently, half of us work with Grails apps, despite the poor Grails support in NetBeans at the moment. We're continuing to work with NetBeans due to it simplicity, small footprint, and design. If the NetBeans community would dig up the Groovy/Grails support, lots of developers will switch to NetBeans I think, and also I'll be very happy, too. :-)

One of coolest things we've created lately is the Crew Look & Feel plugin, which we hadn't released to the public yet and now we think the time has come. It's not too complicated, but a nice little add-in to have, maybe it'll be useful for other users too. Here it is on the Plugin Portal:

http://plugins.netbeans.org/plugin/74527/2pmtech-look-and-feel

Click to enlarge the images below, to get a feel for the new plugin that provides our look and feel:

lnf_1.png

lnf_2.png

NetBeans is my favorite IDE and Apache is one of my technological icons. So, I'm very happy for NetBeans to be migrating to Apache. Apache does not always give you a sweet design, though it does always provide nice UNIX-like tools, and I love it. I hope Apache will make NetBeans not only better, but the best IDE for all Java-based technologies. :-)

[PHP] Conditional breakpoints and new Twig features

Hi all. Today, we will show you some new features which will be available in the next NetBeans version, maybe (NetBeans 10? NOTE: we cannot promise anything about release contents at the moment).

First of all, if you would like to try new features, please build NetBeans yourself.

git clone git@github.com:apache/incubator-netbeans.git
cd incubator-netbeans
ant -Dcluster.config=full
(or ant -Dcluster.config=php)

You can find the start-up files in the nbbuild/netbeans/bin directory if the build succeeds. So please run it.

Debugger: Conditional breakpoints

You can stop the debugger if the context matches your condition. i.e. If the condition is true, the debugger stops on the breakpoint, otherwise, it does not stop there.

I assume that you have already done the settings for debugging. (please see: HowToConfigureXDebug) If xdebug doesn't work, please ask someone via Apache NetBeans mailing lists. (Please don't ask here.)

Just in my case(Ubuntu 18.04):

sudo apt install php-xdebug
sudo vim /etc/php/7.2/mods-available/xdebug.ini

# Change to the following
zend_extension=xdebug.so
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.idekey="netbeans-xdebug"

Let's try running with a sample code(index.php):

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<?php
    $array = ["foo", "bar", "baz", "qux"];
    foreach ($array as $value) {
        echo $value;
    }
?>
</body>
</html>

Step 1: Enable a breakpoint

You can enable it when you click a line number.

Nb-php-debugger-conditial-breakpoint-1.png

Step 2: Show the Breakpoint Properties dialog

To show it, please right-click the breakpoint, then please click Breakpoint > Properties.

Nb-php-debugger-conditial-breakpoint-2.png

Nb-php-debugger-conditial-breakpoint-3.png

Step 3: Input a condition

Please check "Condition" and input your condition to the combo box, then click the OK button.

Nb-php-debugger-conditial-breakpoint-4.png

Step 4: Run Debug Project

Please click Debug > Debug Project or the icon on the toolbar.

In this case, the debugger stops on the breakpont if $value is "baz".

Nb-php-debugger-conditional-breakpoints.gif

Twig: Code completion for delimiters, brackets, and quotes

Twig editor supports code completion for delimeters({{ and {%), brackets([, (, and {), and quotes(" and '). This feature is enabled by default. If you would like to disable, please uncheck the options (Tools > Options > Editor > Code Completion > Language: Twig File).

Nb-php-twig-autocomplete-options.png

Nb-php-twig-autocomplete.gif

Twig: Palette support

You can show the palette window. Please click Window > IDE Tools > Palette.

Nb-php-twig-palette.png

That's all for today. As always, please test it. If you find some issues or enhancements, please report them to JIRA (Components: php - Debugger, php - Twig). Thanks.
