Try it :-)
I was playing with one package from Linux. I grab source code of package using Cygwin. This source code contained one funny file: aux.h.
Windows version of Vim refused to open this file with error message: Permission denied.
Even Notepad refused to open this file.
Finally Visual Studio gave me interesting hint about this aux.h file name:
I tried to zip this file by 7Zip and extract it back. Result was that 7Zip decompressed file as _aux.h.
Interesting issue. :-)
Code smells or anti-patterns are a common classification of source code quality. There is also classification based on food which you can find on Wikipedia.
Spaghetti code is a pejorative term for source code that has a complex and tangled control structure, especially one using many GOTOs, exceptions, threads, or other “unstructured” branching constructs. It is named such because program flow tends to look like a bowl of spaghetti, i.e. twisted and tangled. Spaghetti code can be caused by several factors, including inexperienced programmers and a complex program which has been continuously modified over a long life cycle. Structured programming greatly decreased the incidence of spaghetti code.
Ravioli code is a type of computer program structure, characterized by a number of small and (ideally) loosely-coupled software components. The term is in comparison with spaghetti code, comparing program structure to pasta; with ravioli (small pasta pouches containing cheese, meat, or vegetables) being analogous to objects (which ideally are encapsulated modules consisting of both code and data).
Lasagna code is a type of program structure, characterized by several well-defined and separable layers, where each layer of code accesses services in the layers below through well-defined interfaces. The term is in comparison with spaghetti code, comparing program structure to pasta.
The term “spaghetti with meatballs” is a pejorative term used in computer science to describe loosely constructed object-oriented programming (OOP) that remains dependent on procedural code. It may be the result of a system whose development has transitioned over a long life-cycle, language constraints, micro-optimization theatre, or a lack of coherent coding standards.
Do you know about other interesting source code classification?
