ADB File Extension

Ada Body File – file format by N/A

ADB (Ada Body File) file extension is used by Ada, a structured, statically-typed, imperative, wide-spectrum programming language designed for building large, long-lived applications. ADB files contain the compiled bytecode for Ada source code files.

ADB File Format

An ADB file is an Ada Body File, a type of source code file used in Ada programming. Ada is a structured, statically-typed, imperative, and object-oriented high-level programming language, extended from Pascal and designed for embedded systems. Ada Body Files contain the implementation details of Ada packages, which are modules that encapsulate data and operations.

ADB files typically have the following structure:

  • Package Declaration: Declares the interface of the package, including its name, types, constants, and procedures.
  • Body: Contains the implementation of the package’s procedures and functions.
  • Initialization and Finalization: Includes code that runs when the package is initialized or finalized.
  • Pragma: Defines compiler directives that control the compilation process.

ADB files are used in conjunction with Ada Specification Files (.ADS), which contain the package’s interface and type declarations. Together, ADS and ADB files define the complete implementation of an Ada package. ADB files are typically compiled into object code using an Ada compiler and linked with other components to create an executable program.

Opening ADB Files

ADB files, or Ada Body Files, contain the source code for Ada programs. To open and view the contents of an ADB file, you will need a text editor or a specific Ada development environment. Here are two methods to open ADB files:

  1. Using a Text Editor:

    • Text editors, such as Notepad (Windows), TextEdit (macOS), or gedit (Linux), can be used to open ADB files as plain text documents.
    • Simply open the text editor, navigate to the ADB file, and click “Open.”
    • The ADB file will be displayed as text, allowing you to view and edit the source code.

  2. Using an Ada Development Environment:

    • Ada development environments, such as GNAT Programming Studio (GPS) or AdaCore SPARK Pro, provide a comprehensive set of tools for developing and debugging Ada programs.
    • To open an ADB file in an Ada development environment, simply drag and drop the file into the IDE.
    • The IDE will automatically parse and analyze the ADB file, allowing you to access the source code, compile it, and execute the program.

Definition and Usage

.ADB files are Ada Body Files which contain the implementation of an Ada unit. An Ada unit is a compilation unit that defines a set of related entities, such as variables, constants, types, and subprograms. The body of an Ada unit contains the executable code for the unit and must be stored in a separate file with an .ADB extension.

.ADB files are typically created by an Ada compiler, which translates the source code of the unit into executable code. Once compiled, .ADB files can be linked together with other object files to create an executable program. Ada programs are typically cross-compiled on one platform and then run on another platform, providing portability across different hardware architectures.
