Integration with existing languages

In previous versions of MPS, we used so-called "stub" models to reference code written in Java and there was no possibility to do the same thing for a new language. In MPS 1.5 the stubs aspect was added to a language - using it, one can describe how to "load" an external code of a language into MPS to be able to reference existing non-MPS code from MPS.

Other improvements

In addition to all the features above MPS 1.5 contains a number of other improvements listed below:

  • DSL for creating and editing GWT client application manifests
  • DSL for adding Type Extension Methods
  • Couple of Base language extensions
    • Checked dots
    • Overloaded operators
    • Custom constructors
  • API for integrating arbitrary low-level programming language capable for loading existing code and exposing it in MPS
  • improved error reporting - references out of search scope are marked with the error in editor
