Is there a way to get the raw XML text which another plugin has contributed to an extension point?
The normal way to access data that is contributed to an extension point is to use IConfigurationElement objects:
IConfigurationElement[] configElems = Platform.getExtensionRegistry()
.getConfigurationElementsFor(LANGUAGES_EXTENTION_POINT_ID);
But I already have JAXB parser for the kind of data that is contributed to this extension point. I'd like to use that one instead of Eclipse's classes.
EDIT 1: An alternative would be to use some kind of Eclipse-configuratoin-to-JAXB bridge library. But I don't find any.
EDIT 2: It's probably possible to find the plugin.xml of the contributing plug-in and read that manually... Probably not a good idea.
EDIT 3: I think I will do this: Instead of contributing the data directly clients get to give a file name. I then read that file using my old parser.
No, I don't see anything that would give you the XML.
getConfigurationElementsFor gives you information extracted from many different plugin.xml files so it is not clear what XML could be returned anyway.
org.eclipse.core.internal.registry.ExtensionRegistry is the extension registry implementation, but a lot of the information that uses comes from org.eclipse.core.internal.registry.RegistryObjectManager.

I have a custom XML format that links to Java resources. For the sake of simplicity let's assume my XML file would look like this:
<root>
<java-class>my.fully.qualified.class.name</java-class>
</root>
Eventually my references will be somewhat more complicated. It will not contain the fully qualified class name directly and I will need some logic to resolve the correct class, but I want to keep the example as simple as possible here.
Now I want it to be possible to Strg+Click on the element's text and want IntelliJ to carry me to the .java file, just like it is possible in Spring-XML files. In the IDEA Plugin Development FAQ there is a link called "How do I add custom references to Java elements in XML files?" which so much sounds like exactly what I need. Unfortunately it links to a discussion where someone is more or less done implementing something like this, having some minor problems. Nevertheless I understood that I probably need to write an implementation of the interface com.intellij.psi.PsiReference. Googling for "PsiReference" and "IntelliJ" or "IDEA" unfortunately did not bring up any tutorials on how to use it, but I found the class XmlValueReference which sounds useful. Yet again googling for "XmlValueReference" did not turn up anything useful on how to use the class. At least the PSI Cookbook tells me that I can find the Java class by using JavaPsiFacade.findClass(). I'd be thankful for any tutorials, hints and the like, that tell the correct usage.
The above linked discussion mentions that I need to call registry.registerReferenceProvider(XmlTag.class, provider) in order to register my provider once I eventually managed to implement it, but of which type is "registry" and where do I get it from?
First of all, here's a nice tutorial that came up a few days ago, which explains the basics of IntelliJ plugin development (you should take a look at the section Reference Contributor).
You will likely have to define your own PsiReferenceContributor, which will be referenced in your plugin.xml like this:
<psi.referenceContributor implementation="com.yourplugin.YourReferenceContributor"/>
In your reference contributor, there's a method registerReferenceProviders(PsiReferenceRegistrar) where you will be able to call registry.registerReferenceProvider(XmlTag.class, provider).
Finally, in your instance of PsiReferenceProvider, you will have to test the tag name to filter out tags which don't contain class references, then find the right Java class using JavaPsiFacade.findClass().
From my experience, the best place to get help regarding IntelliJ plugin development is JetBrains' forums.
I have files named xxx.java.i,xxx.java.d,xxx.jar.i. I know that these file are somehow related to Java. What does this extension mean and for what is it used? Is it same type as the .class extension?
You should look at your build system for more information. It is possible that these are intermediate files that get transformed and renamed to ".java". For example, I've seen various build systems that use the ".i" suffix to mean "input", and perform various forms of variable substitution (e.g. changing something like "{VERSION_NUMBER}" to the version number of the library being compiled).
I think they are created by someone to serve his own purpose and unless we ask the author or see the content we won't know what it the purpose is.
If you see garbled characters, it's probably java bytecode and you can use some decompiler to see the code (see: How do I "decompile" Java class files?).
I'm working on a project for the iPad, I need to read and write to an xml file, which is also used by the counter part of the application in windows.
The problem that I have is that I've been looking around but I haven't found a way to modify an element or attribute in an xml, without having to build the whole xml again.
I saw this other post, which is basically the same problem that I have, and I also end it up in the same point as the person asking the question, NSXMLParser and TouchXML are read only and do not allowed me to modify my xml.
Any other suggestion about what can I use?
Thanks!
By default all I get in intellisense are the functions and its signature. I would prefer if I could also get documentation with the intellisense. I realise that I am supposed to place an xml file that contains this documentation along with my dll.
From where can I get this is file? Or is there some other way for me to achieve this?
For the immediate future, there's no way to get the XML documentation short of grabbing the Structuremap source and building it yourself.
As for why that's not included with the distribution, I'm not sure. My only guess is that back when xml-based configuration with SM was more prevalent, Jeremy was concerned about confusion between StructureMap.xml the intellisense file, and StructureMap.xml the configuration file.
That's pure speculation however. For the real scoop you'd have to post on the SM-mailing list. Regardless, for the time being, you have to roll your own from the source. I've done this as well for the same reason, and it wasn't too painful.

Edit - Instructions for doing this follow.
Using your favorite SVN client (if you don't have one, I recommend TortoiseSVN) grab the latest from https://structuremap.svn.sourceforge.net/svnroot/structuremap/trunk/ . If you want the same bits that are in 2.5.3, I think you'll want revision 234. Otherwise, just grab the head and build from that. (If you aren't familiar with SVN, find a tutorial that explains what I'm talking about)
Open up the StructureMap solution in Visual Studio (under the Source subdirectory). Right click the StructureMap project, Go to Properties > Build and ensure the option for XML output documentation is checked.
Build and enjoy.
What is a tool or technique that can be used to perform spell checks upon a whole source code base and its associated resource files?
The spell check should be source code aware meaning that it would stick to checking string literals in the code and not the code itself. Bonus points if the spell checker understands common resource file formats, for example text files containing name-value pairs (only check the values). Super-bonus points if you can tell it which parts of an XML DTD or Schema should be checked and which should be ignored.
Many IDEs can do this for the file you are currently working with. The difference in what I am looking for is something that can operate upon a whole source code base at once.
Something like a Findbugs or PMD type tool for mis-spellings would be ideal.
As you mentioned, many IDEs have this functionality already, and one such IDE is Eclipse. However, unlike many other IDEs Eclipse is:
A) open source
B) designed to be programmable
For instance, here's an article on using Eclipse's code formatting functionality from the command line:
http://www.peterfriese.de/formatting-your-code-using-the-eclipse-code-formatter/
In theory, you should be able to do something similar with it's spell-checking mechanism. I know this isn't exactly what you're looking for, and if there is a program for doing spell-checking in code then obviously that'd be better, but if not then Eclipse may be the next best thing.
This seems little old but seems to do a good job
