Compare and merge/mark on Regeneration Xtext-Xtend [message #1762853]

Hi All,
I recently made Xtext-Xtend app to generate C++ classes.

Some code needs to be typed externally, as for instance the implementation of functions.

However, whenever I regenerate the files all the manually written code is deleted.

Is there a way to Compare and Merge/Mark files when regenerating?

Thanks

you ususally use the generation gap pattern for that. Abstract Generated Superclass, Subclass With Manual Code is Generated once. Xtext supports this by having different OutoutConfigurations.
if you really want protected regions you might need to port https://github.com/danieldietrich/xtext-protected-regions to the current version of xtext
