File Format Description

Class implementation file used by programs written in Objective-C; begins with the @implementation directive; initializes variables and functions that can be referenced by other Objective-C source files; may also reference header (.H) files.

Objective-C is most commonly used to implement applications for Apple's Mac OS X and iOS operating systems. Apple's Cocoa API provides the Objective-C programming interface for Mac OS X, and the iOS API provides the programming interface for the iOS platform.

Mercury Source Code File

File Format Description

Source code file written using the Mercury functional programming language, which was developed at the University of Melbourne, Australia; saved using plain text formatting and uses syntax similar to the Prolog language.

Mercury was written in order to provide a robust language for large real world applications. It includes several error-checking features not provided by other logic programming languages. For example, the language incorporates static analysis that can catch type checking errors before runtime. This enables greater assurance over the correctness of the program and also allows the compiler to generate more efficient code. However, the developer must specify each of the "type," "mode," and "determinism" constructs while programming, which is not necessarily required by other languages.

NOTE: The developmental version of the Mercury compiler is currently distributed in a source code format and does not include compiler binaries. However, a Windows port of Mercury, called winmercury, includes binaries. It also includes Vim syntax highlighting files for source code editing.
