Does my variable naming convention have a name?

Question

So I go by this Delphi naming scheme of arguments start with A, class vars start with F and local vars start with M. Does that scheme have a name? I see it a lot in the Delphi source I'd like to read more about it but I'm not sure what it's called.

Answer 1

This coding style is specifically called out in the Object Pascal Style Guide as not being Hungarian notation (with one exception, enumerated types.)

The specific coding conventions you're talking about don't have a name as such, as far as I know, it's simply that you're writing code conforming to the CodeGear (old Borland) coding style guide. The guide doesn't seem to give the style a name.

The reason you see it a lot in the Delphi source is because this guide is based on the coding style the Delphi team developed!

This document's well worth reading - not only for code guidelines but also out of interest for other things it mentions.

Your schema can be considered some form of Hungarian notations (HN). Usually HN is used to signify the type of a variable, but as Wikipedia notes,

The notation is sometimes extended in C++ to include the scope of a variable, separated by an underscore. This extension is often also used without the Hungarian type-specification: [..]
