Huvudkod

Huvudkod is a Swedish term that translates roughly as "main code" or "head code." In Swedish technical and educational contexts it is used to refer to the central portion of a software program—the core source code that implements the primary functionality. The term is informal rather than a formal programming construct, and its exact meaning can vary by organization or context.

In practice, huvudkod can denote several related concepts. It often describes the entry point or the main function of a program, especially in languages where the entry point is explicit. More generally it can refer to the module, class, or set of routines that contains the essential business logic of an application. Huvudkod is commonly contrasted with peripheral or supporting code, such as test suites, configuration files, scripts, or scaffolding used for development and deployment.

The term is frequently used in documentation and learning materials to emphasize readability and maintainability of the core logic. When teams discuss refactoring or code quality, they may focus on the huvudkod to ensure that the central behavior remains clear, well-tested, and robust.

Because huvudkod is informal, its interpretation depends on context. Developers should ensure shared understanding within a project by defining what counts as huvudkod in their guidelines. See also: main function, entry point, core code, source code.
