gmStudio's code analysis and translation capabilities may be extended and modified through various rules files and scripts.  A collection of sample rules files and script is cataloged here.

Migration Rules Files

Migration Rules Files (mig Files) are the preferred means of mapping a COM API to its replacement in .NET.   

See Using Mig.IDF Files for COM API replacement


Custom Interface Description Files (IDFs)

Custom IDFs allow you to migrate COM APIs to .NET replacements. This is a powerful and fairly intuitive technique, but it is not as maintainable as Migration Rules files. 

The gmStudio samples use custom IDFs files, but this approach will be phased out in favor of using Migration Rules  files. See Custom COM Replacement.


gmSL Scripts

gmSL scripts may be used to implement dynamic translation rules for various COM migrations in concert with custom IDFs and mig files.  gmSL Scripts may also be used for special purpose analysis and transformation on their own. 

Note we also offer a .NET API that has all of the power of gmSL and may be used to build custom translation engines as .NET executables.   Learn more about gmsl here: gmSLIntroduction.
