Conditionscontexts

Conditionscontexts is a term used to describe the relationship between a condition and the contextual information that affects its evaluation. The phrase is not widely standardized but is used in some discussions to emphasize that whether a condition holds can depend on factors such as the current state, environment, user role, time, locale, and device.

In formal models, a condition is a boolean predicate and the context is the set of facts and assumptions available when evaluating the predicate. The concept is used in logic, rule-based systems, context-aware computing, and software configuration, where conditions are interpreted differently depending on context.

An implementation approach is to pair a condition with a context object, or to define a satisfaction relation that includes both. This helps avoid misinterpretation of terms that are valid only under certain circumstances.

Examples help illustrate the idea. In a feature-flag system, a condition such as "user is admin" applies only within a context where the user has the admin role and the system locale supports the feature. In accessibility settings, a condition "text size large" depends on the context of the user's accessibility preferences and device capabilities.
