xtext importURI外部文件 [英] xtext importURI external file

问题描述

我非常失望，导入全球范围是如何工作的。我正在为一个井结构语言编写一个带有xtext的解析器，我不能依赖于工作空间或项目概念。在我的语言中，我有包含可以具有另一个文件的相对或相似路径的语句。我需要能够引用在这个其他文件中定义的对象。我尝试使用importURI，但它不工作。我试过的是添加这个规则：

  Include：
'INCLUDE''='importURI = STRING' '
; 
  

并更改了这些部分的MWE2文件：

  //范围和导出API 
 fragment = scoping.ImportURIScopingFragment {} 
 // fragment = exporting.SimpleNamesFragment {} 
 
 //范围和导出API 
 fragment = scoping.ImportNamespacesScopingFragment {} 
 fragment = exporting.QualifiedNamesFragment {} 
  

但是这在编辑器中没有任何影响。我仍然可以引用在每个文件中定义的对象，具有相同的扩展名，而没有include语句，我仍然不能在项目之外包含文件。

解决方案

解决方案是从工作流程中删除这两个。

  //为java类型集成提供必要的绑定
 // fragment = types.TypesGeneratorFragment {} 
 
 //只有当语法从Xbase 
继承时才产生所需的绑定// fragment = xbase.XbaseGeneratorFragment {} 
  

i am very lost with how importing global scope is working. I am writing a parser with xtext for a well structure language and I cannot depend on workspace or project concepts. In my language I have include statements which can have relative or absoloute paths of another file. I need to be able to reference objects defined in this other file. I tried using importURI but it doesn't work. All I tried was to add this rule:

Include:
    'INCLUDE' '='  importURI=STRING ';'
;

and changed the MWE2 file in these parts:

   // scoping and exporting API
                 fragment = scoping.ImportURIScopingFragment {}
                // fragment = exporting.SimpleNamesFragment {}

                // scoping and exporting API
                fragment = scoping.ImportNamespacesScopingFragment {}
                fragment = exporting.QualifiedNamesFragment {}

But this doesn't make any effect in my editor. I still can refer to objects defined in every file with the same extension without having the include statements, and I still cannot include files outside of the project.

解决方案

the solution was to remove these two from workflow.

 // provides the necessary bindings for java types integration
 // fragment = types.TypesGeneratorFragment {}

 // generates the required bindings only if the grammar inherits from Xbase
 //fragment = xbase.XbaseGeneratorFragment {}
