Here is what the text looks like at the bottom of a typical C++ file I
edit:
/*
Local Variables:
typedefs:("boost" "noncopyable" "shared_ptr" "size_t" "std" "string"
"tCursorIPtr" "tDestroyI" "tEndian" "tStreamI" "tStreamIPtr" "wchar_t"
"wstring")
End:
*/
So the value of "typedefs" is just a list of quoted symbols. This list
changes from file to file. It is used by the syntax highlighting code
in C/C++ mode.
The question therefore remains, what can I do so that all such values
of typedefs are always considered "safe". I'm not certain why this is
being flagged in the first place, as the documentation I saw about
ricky variables indicates that their name should end in some special
characters, and my typedefs do not end in such characters. So I have
been confused from the start why this is marked as risky in the first
place and therefore why I am being queried about it each time I open
the file.
Thanks again,
