Bug Fold All/Unfold All: cause // { comments

Gilles Gipo

Notepad++ v7.5.4
I wondered why the “Fold All (Alt+0)” didn’t work for a unique module of functions (javascript).
(after 4 functions folded, the 5th and following were unfolded)

I’ve found the reason :
folding/unfolding can see the { and } in the comment lines ! With bad understanding…
Ex :

var module = (function(){
    function myfunc(){// can be folded but not the following functions
        for(var i=0; i<myVar.length; i++){
            //if(i != iTab){ // cause of the bug : the { in a comment
            (...)
            //}
        }
     }
     function myfunc2(){// can't be folded by "View..Fold All"
     }
    (...)
})();

If it can help… :)

This is not a bug, but rather a confusing feature that is implement by Scintilla (the core piece Notepad++ uses). It allows //{ and //} to be used to create custom fold points. You can turn this off but you need a plugin such as LuaScript or PythonScript. With LuaScript if you edit the startup script you can add the following lines and restart N++:

npp.AddEventHandler({"OnSwitchFile", "OnLangChange"}, function()
	if editor.LexerLanguage == "cpp" then
		editor.Property["fold.cpp.comment.explicit"] = "0"
	end
end)

@dail Oh ! OK, I understand, now…
It’s totaly logic, but I dindn’t think to see in that direction.

The solution is easy to find, now : I only have to cope with this, and avoid to stick those specific characters :)
…and it works!
Thanks! :D

        //if(i != iTab){ // a space beetween { and //
        (...)
        // } // a space beetween // and }
