I use a xtext generated DSL in my project. I now want to generate some files with a wizard. I can currently create these files just by adding some strings to the file. But initially i wanted to create a Model Object of the DSL and add the new generated file to the resource set. I can't find a way accessing this without the StandaloneSetup of the DSL.
I'm now unsure if the use of the StandaloneSetup inside the Editor is the correct way, since it seems there should be a better way to access the already build up resource set used by the xtext framework to manage the already known files/sources. If i use the StandaloneSetup shouldn't there be 2 Injectors which could get really bad?
you can use the resource service provider registry to obtain the injector

URI fakeOrRealUri = ...;
IResourceServiceProvider.Registry.INSTANCE.getResourceServiceProvider(fakeOrRealUri).get()

Our service implements different levels of access and we are using one openAPI YAML file internally.
For external documentation purposes, we would like to create multiple openAPI files, that are valid in themselves (self-sustained), but only have a partial set of the global file, e.g. based on the path or on tags.
(The same path may be used in different split-Files but I don't think that is a problem then.)
Any idea on how to achieve that? Is there some tooling around for it?
You can use a valid URI in a JSON Pointer which points to another resource. The URI can be a path to a local file, a web resource, etc.:
paths:
/user/{id}:
summary: Get a user
parameters:
- $ref: "./path/to/file#/user_id"
# And so on...
Reserved keys in the OpenAPI spec must be unique so I don't think you'd be able to create standalone OpenAPI specs without some third-party utility that could overcome that limitation.
However, you would be able to create valid standalone JSON objects defined across many files and reference them in the index document. There are many articles online providing examples:

I ended up writing a Python script, that I have posted here.
Flow
Read the YAML File into a dictionary
Copy the dictionary to a new dictionary
Iterate through the original dictionary and
Remove items that are not tagged with the tag(s) you want to keep
Remove items that are have some keyword you want to omit in the path
Write out the dictionary to a new YAML

I'm trying to create a custom annotation processor that generates code at compilation time (as hibernate-jpamodelgen does). I've looked in the web, and I find custom annotation processors that works with maven, but do nothing when added to the Annotation Processing > Factory Path option. How could I create a processor compatible in this way? I have not found a tutorial that works.
My idea is to, for example, annotate an entity to generate automatically a base DTO, a base mapper, etc that can be extended to use in the final code.
Thank you all
OK, Already found out the problem. The tutorial I hda found out dint't specified that, in order to the compiler to be able to apply the annotation processor, there must be a META-INF/services/javax.annotation.processing.Processor file that contains the qualified class name of the processor (or processors).
I created the file pointing to my processor class, generated the jar and added it to Annotation Processing > Factory Path and all worked correctly.
Just be careful to keep the order of the processors correctly (for example, hibernate model generator claims the classes, so no more generation will be made after it), and change the jar file name each time you want to replace the library (it seems eclipse keeps a cache). These two things have given me a good headache.
Thanks all
In my custom Eclipse plugin, I have the fully qualified class name of a Java class as a String, and want to know its actual file path. In fact, I want to know the name of the source folder it resides in.
The class could be from any of the Java projects in the Workspace. The source folder names are arbitrary.
I use Eclipse 3.6.
Thanks!
You will have to use the search engine API. See org.eclipse.jdt.core.search.SearchEngine.
You can see that there are various static functions you can call, each with their own options. You will need to create an appropriate org.eclipse.jdt.core.search.SearchPattern and then pass it to the search engine along with a scope (the workspace) and a requestor (something that gathers all of the results).
Typically, you will get a bunch of stuff back, like ITypes, which are the public API for accessing types in the Java model. You can call IType.getResource().getLocation() to get the filesystem location of any type. The getResource method may return null, so you need to check for that.
You will need to use the JDT API stuff to get to the IResource of the Java class. From there you can use the Resource API to get the containing folders and whatever else you need.
When I'm generating/refreshing my model from the database, how do I specify which template to use?
At the moment, despite having my new template, it still uses the default. Then I have to go in and clear out the contents of 'MyDatabase.Designer.cs', then manually go in to my template and run it.
Surely I can just specify which template my model should use?
At first, you should disable the default code generation. The simplest solution is to clear the Custom Tool property of the model file.
After this just run your template.
There is even simpler way: go to the model Properties and set the Code Generation Strategy property to None.
I am trying to create Web Services from the Top-Down approach. I downloaded Eclipse and am using the WSDL gui editor in it to build my WSDL files.
I am splitting up my Services based on "modules". The Types I am adding to the WSDLs all need to reference common stuff, such as PersonEntity, AddressEntity, States enumeration (simple type), Countries enumeration (simple type), and AbstractEntity. Since those items are all common I created a seperate WSDL file (named Commons.wsdl) that contains the type information for those types.
I want to "import" that WSDL into my other WSDL files to use:
For example, I have an entity named RegistrationEntity which inherits from AbstractEntity and contains a PersonEntity as well as an AddressEntity. I'm not sure how to do this... I saw that the WSDL spec has "import" and "include" and am not sure which one to use. Also, how do I actually import (or include) the Commons.wsdl file so that I can use the Types defined within it?
Thanks!
Oh, and I'm not sure if I'm supposed to stick this stuff in a seperate WSDL but another type of file such as an xsd or something. I really wanna follow best practices so if that's the proper way to do it then I'd rather do that.
I found out that the problem I had was I was creating a WSDL file for my commons and using an inline scheme for that, rather than creating an XSD file to be imported by my other WSDLs.
So instead I just created an Commons.XSD as my "Common Schema".
