April 2018. Great Migrations is pleased to announce a major break through in software re-engineering: a .NET API for automating the gmBasic upgrade engine and accessing the semantic models produced by our unique linguistic compilation technology.
...
The API includes special purposes classes to help you integrate API-based EXE upgrade tasks with gmStudio and customize their behavior. EXE upgrades tasks can be used in gmStudio using procedures very similar to those for gmPL script tasks. The main difference is the EXE tasks are implemented in C# (or VB.NET) using Visual Studio while gmPL script tasks are implemented in XML using your favorite code editor.
We The API is still evolving rapidly so we consider this release a beta, but we have already developed a C# version of the WPF transformation logic using this API and also we have used it with C# to implement several very large multi-feature upgrade solutions. Additional documentation and samples using the API will be published soon. Please Contact us if directly if you are interested in learning being part of the beta-test or discussing how this technology can help you.

Preview the draft .NET API documentation here. |
A sample upgrade program using the API is shown here. Notice that it use WPF Subsystem logic that is implemented in a C# assembly.
...
The example also shows how to load source and edit the source in memory prior to translation. To use this, API you need to reference gmslAPI.dll from the gmStudio distribution and also make sure you choose Platform Target x86 since the gmBasic engine is presently a 32bit technology. Contact Great Migrations if you are interested in a 64bit build.
