Importer and exporter

This page describes language that you can use to import and export data from other languages or models. If you need a tighter integration into MPS with the original files existing, use custom persistence ⧉. This approach is an advanced feature that is not used often.

ECore

com.mbeddr.mpsutil.ecore

This language contains an importer and exporter of the metamodel (ECore ⧉) of the Eclipse Modelling Framework. The conversion is between an XML file and an MPS model. The importer can import Ecore and Ecore model files.

Access the action by right-clicking a model and opening the Ecore Transformation tools group.

XML Import

com.mbeddr.mpsutil.xmlImport.plugin

This plugin adds two actions for importing XML files into MPS:

  • Paste as XML Content: This action is located in the editor context menu, parses XML code, and adds it to the next XML node or root node.
  • Import XML File(s): This action parses on or multiple XML files and creates XML root nodes for them in the selected model.

JSON

com.mbeddr.mpsutil.json

This language implements a simple JSON language you can use as a generator target. The JSON file ⧉ root node supports an additional package name used as the folder inside the generation folder.

An example of a file that you can generate:

{ 
  "description" : "This is a JSON file", 
  "name" : "my JSON file", 
  "this is an object" : { 
    "And another object" : { 
      "With a description" : "object description", 
      "An array" : [ 
        "valu1", 
        "value2" 
      ], 
      "withANumber" : 1.232E+231231, 
      "empty array" : [ ], 
      "empty object" : { }, 
      "empty string" : "" 
    } 
  } 
}

An importer also exists for the language. It can import all JSON files in a folder or just single files.
