Netbeans for C++

I've been using Netbeans for C++ development. One of the big issues I had is getting the Netbeans Code Assistance feature to work properly. Meaning, I want:

• syntax highlighting
• code completion
• refactoring
• call graphs

In short, everything I expect from Netbeans when using Java. I am dealing with a large CMake based project, with existing sources. So I build the project manually, and CMake emits the Makefiles. Now I have a project that netbeans can open (an "existing Makefile based project"). The next thing you need to do is set your include directories (shown below). 

Now this is where things get weird. Despite having set the includes several times none of the Code Assistance features worked. I tried deleting the NB cache, restarting, etc, etc. Nothing worked. If I write click on the project, and select Code Assistance I can dump the diagnostics. Notice how the user include paths that I entered ARE NOT PRESENT? WTF?

 from project main [/Users/ghendrey/git/main]

Lang=CPP Flavor=CPP excluded=false

User Include Paths:

User Macros:

System Include Paths:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1

/usr/local/include

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/6.0/include

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include

/usr/include

/System/Library/Frameworks

/Library/Frameworks

But, my user includes are not showing up! Finally, I tried Project > Properties > General and added my "src" folder to the "Project Source Folders". Now this seems like a bit of a "duh", but it wasn't obvious, since "." was already listed under project source folders, which presumably grabs everything. Furthermore, once I save the properties, and close the dialog, the "src" folder disappears, and only "." is shown. HOWEVER, it seems that adding "src" somehow kicked started the Code Assistance. Now  I see the correct user includes when I dump the diagnostics:

 from project main [/Users/ghendrey/git/main]

Lang=CPP Flavor=CPP excluded=false

User Include Paths:

/Users/ghendrey/splunk/current/include

/Users/ghendrey/git/main/src

/Users/ghendrey/git/main/src/libzero

/Users/ghendrey/git/main/src/util

User Macros:

System Include Paths:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1

/usr/local/include

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/6.0/include

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include

/usr/include

/System/Library/Frameworks

/Library/Frameworks

And lo and behold, all of code completion is working. Incidentally, the Code Assistance right click menu is often broken (several of the items become unelectable until I close the project and restart netbeans). So, if you can deal with these annoyance, once you (finally) get up and running with code assistance in netbeans, it is a way way better c++ development environment than eclipse. 

Why oh why did I just waste the day on this shit?

I just missed tucking my daughter in because I've been trying to wrangle Jersey's Moxy into working properly. Jersey guys: you have done great work, but this Moxy thing is a PIECE OF SHIT. I'm sorry, but I am tired and grumpy. I have used Jackson so successfully with Jersey in the past, but I wanted to believe your docs on Moxy. I wanted to believe it would "just work". Boy...moxy sucks. I should have just stuck with Jackson. I'm so pissed off I need to write a silly blog post to calm down. What really pisses me off, is every single thing I was trying to make work with Moxy, just immediately worked when I switched to Jackson.

Thank god for Stack Overflow: http://stackoverflow.com/questions/29322605/how-to-return-a-json-object-from-a-hashmap-with-moxy-and-jersey

I should have listened to the answer better. Apparently the answer to how to get Moxy to work is not to use Moxy.: "For this reason, and actually many others I have encountered in the past, I do no recommend using MOXy even though it is recommended by Jersey. Instead, use Jackson. Jackson has been the defacto Java goto for JSON processing for a while. For Jackson, just use this dependence".

Another annoyance in this whole fiasco has been that the interwebs are littered with descriptions of how to use ResourceConfig...but there are multiple versions of ResourceConfig. What the fuck?

https://jersey.java.net/apidocs/2.4.1/jersey/org/glassfish/jersey/server/ResourceConfig.html
https://jersey.java.net/apidocs/1.1.5/jersey/com/sun/jersey/api/core/ResourceConfig.html

They have different interfaces. So you'll find a snippet like this, which pertains to the old 1.1.5 API. Thus totally confusing the fuck out of you: http://stackoverflow.com/questions/9490123/how-do-i-enable-pojo-mapping-programatically-in-jersey-using-grizzly2

Moxy blows. Jackson rules. Punk is out. Rap is in.

ActiveMQ: Your "Hello World" really should work...

I just downloaded ActiveMQ and started running the basic Publisher/Listener example. Now, sort of the first thing I would expect from this example would be that the count of received messages would be accurate. But alas, it seems all too common, for Hello World not to work.  Sure enough, Publisher publishes 10000 messages, Listener reports "Received 10001 in 1.66 seconds". One extra message! WTF. Ahh, I see, you're loop count is broken. Really?

	long count = 1;
	System.out.println("Waiting for messages...");
	while (true) {
	Message msg = consumer.receive();
	if (msg instanceof TextMessage) {
	String body = ((TextMessage) msg).getText();
	if ("SHUTDOWN".equals(body)) {
	long diff = System.currentTimeMillis() - start;
	System.out.println(String.format("Received %d in %.2f seconds", count, (1.0 * diff / 1000.0)));
	connection.close();
	try {
	Thread.sleep(10);
	} catch (Exception e) {}
	System.exit(1);
	} else {
	try {
	if (count != msg.getIntProperty("id")) {
	System.out.println("count: "+count + " mismatch: " + count + "!=" + msg.getIntProperty("id"));
	}else{
	System.out.println("count: "+count + " match: " + count + "==" + msg.getIntProperty("id"));
	}
	} catch (NumberFormatException ignore) {
	}
	if (count == 1) {
	start = System.currentTimeMillis();
	} else if (count % 1000 == 0) {
	System.out.println(String.format("Received %d messages.", count));
	}
	count++; //<----ARGHHHHHHHHHHHH
	}
	} else {
	System.out.println("Unexpected message type: " + msg.getClass());
	}
	}
