featuretrue

Featuretrue is a term used in software engineering to describe the state where a feature is considered enabled and accessible because the controlling feature flag evaluates to the boolean value true. It is often used in discussions of feature flags, feature toggles, and progressive delivery. The phrase emphasizes the active state, as opposed to false, which denotes the feature being hidden or off, and not yet visible to users. The term is not standardized and appears in informal documentation and within some teams as shorthand.

In practice, featuretrue corresponds to a flag value of true in a configuration store, environment variable, or code-controlled toggle. It supports controlled releases: features can be turned on for internal testing, gradually rolled out, or rolled back by flipping the flag to false. Implementation considerations include ensuring deterministic behavior across services, managing flag lifecycles, and handling state in distributed systems. Featuretrue can interact with targeting rules, user segments, or percentage-based rollouts that determine when the 'true' state should be active for specific users.

Limitations include flag sprawl, configuration drift, and the need for robust testing to cover both enabled and disabled states. Some teams document the concept as part of their feature-management strategy to keep readers aware that the 'true' state corresponds to the active feature.
