And to say that any file with the sc extension has to be exactly like Rockstar's code is just plain foolish. You can give a text based file any extension you want. If I want to use .sc for my uncompiled code I can do that. I've got my Notepad++ setup to always format those files like Sanny does if I want to edit the files with that. So it makes sense on multiple levels.
In exceptional case it's still possible to assign Sanny Builder to .sc files manually:
Click right on .cs file -> Properties.
Opens with -> Change
If there's no Sanny Builder on list of programs, then click Browse.
Go to Sanny Builder, select "sanny.exe"
Path of Sanny Builder is most likely to be somewhat like "C:\Program Files (x86)\Sanny Builder\"
And to say that any file with the sc extension has to be exactly like Rockstar's code is just plain foolish.
As i wrote, you can have a script with .jpg extension. But that doesn't make sense as to why someone would use .jpg extension for a script file.
It would be better if Sanny Builder files have got different official extension, for example .sbs (Sanny Builder script).
I mean, let .sc be R* script and leave it assigned to R*-like compiler if exists.
