xtext

问题 I haven't had success in installing Xtext with Eclipse (see Xtext Bundle org.eclipse.emf.mwe.utils cannot be resolved and Can't Create Xtext Project in Eclipse), so I thought I'd try IntelliJ IDEA. However, when I created the default project, I got the error "Couldn't Resolve Reference to Grammar 'org.eclipse.xtext.common.Terminals'". Isn't this library automatically installed with Xtext? At this point, I am stuck. Can anybody definitively resolve this problem? 来源： https://stackoverflow.com

问题 I have a Xtext grammar which throws following exception when I try to generate Xtext artifacts (It starts and in the end it throws the exception(s)). My Outline (first few lines): 0 [main] INFO lipse.emf.mwe.utils.StandaloneSetup - Registering platform uri 'C:\Users\Robert Adam\Documents\eclipse.luna\workspace' 451 [main] INFO lipse.emf.mwe.utils.StandaloneSetup - Adding generated EPackage 'org.eclipse.xtext.xbase.XbasePackage' 701 [main] INFO clipse.emf.mwe.utils.GenModelHelper - Registered

问题 What I'm trying to do, is modify a bit the basic entity DSL example, so that it supports primitives, and something like this can be done: entity Dog { name : String } entity Person { name : String dog : Dog } So that the type of the members can be either a reference to the name of another entity, or a predefined primitive. I'm also looking for a way, so there is content assist in the generated editor for both the primitives, and the entity names. Here is my .xtext so far: Model: (entites+

问题 I am using the following code in JvmModelInferrer.xtend to generate a Java class @Inject extension JvmTypesBuilder def dispatch void infer(Model element, IJvmDeclaredTypeAcceptor acceptor, boolean isPreIndexingPhase) { acceptor.accept(element.toClass(element.name)) [ annotations += annotationRef(Inject); ] } When I try to run the whole project, I get the following error. 5226 [main] ERROR org.eclipse.xtext.xbase.jvmmodel.JvmTypesBuilder - Error initializing JvmElement java.lang

问题 My current project (name it IoTSuite) takes high-level specifications, parses them, and generates code in Java and Android. In this project, I have written ANTLR grammar to parse the high-level specification and I have used StringTemplate for the code generator. However, due to nice editor support and syntax coloring features, I have used the xtext grammar(same as the ANTLR grammar, but it has been written in xText). Now, I perform the following three steps: Step 1: I have written xtext

问题 I'm developing a DSL using Eclipse's Xtext framework. For the content assist/code completion, I have an expensive process which generates me a list of strings. How do I cache the result of that process? Long story: My DSL interfaces with Groovy scripts. The scripts provide methods which I offer in certain places in my DSL. This is pretty slow, even when I use a regexp to parse the methods of the scripts. So I'd like to cache the results of the script analysis. From my analysis, the analysis

问题 I am in the middle of an Acceleo Transformation aimed at producing code (i.e. Java) from an input UML model. Some elements of this UML model (i.e. Activities Opaque actions) contain some text which is conform to an Xtext grammar and I'd like to get the equivalent AST Ecore representation in the Acceleo transformation. To this end I have developed a Java class with a method which takes as input a string, containing the DSL excerpt, and produces an Ecore model conform to it (see http://www

问题 This has got to be one of those well-known examples that's somewhere on the internet, but I can't seem to find it. I'm trying to learn XText and I figured a calculator expression parser would be a good start. But I'm getting syntax errors in my grammar: Expression: Term (('+'|'-') Term)*; Term: Factor (('*'|'/') Factor)*; Factor: number=Number | variable=ID | ('(' expression=Expression ')'); I get this error in the Expression and Term lines: Multiple markers at this line - Cannot change type

问题 I have been searching quite a lot for this problem, however I can't really find a proper solution or a how-to manage this one. I have written a simple DSL for generating some code via Xtext and Xtend. I optionally use the project wizard in the UI project of Xtext to be able to create an individual project for my grammar and plugin. I am able to create the project with ease, however I still need to add some important dependencies into my class path of the clients project. It seems to be a bit
