Hi Denis, In a project of my own I encountered the same issue. This program moves a go project to another location, then it remembers imports (that are necessary), exported types, functions and package-scope values (var / const) and maps them in the original go project to the newly created one. The original goal of this program is to move packages from other packages, while leaving everything compatible as is. Everything almost works now but in practice, all my code has a strange look, like function/type definitions are all stuck with one another, with no lines in between.
If anyone has suggestions or ideas, please let us know! Thanks to all of you for your time.
