Lineara

Lineara is a fictional formalism used in theoretical computer science and speculative literature to model systems with strict linear resource usage. In lineara, programs manipulate values that are subject to linear typing: each value is intended to be produced and consumed exactly once, and arbitrary duplication or disposal without accounting for usage is disallowed. The central aim is to study how resource flow and state changes interact under explicit constraints on how data can be created, transformed, and released.

Formalism and structure

A lineara framework describes types and a set of operations that preserve linearity. Values carry usage annotations that track how many times they may be, or must be, used. Functions can take lineara values as inputs and produce lineara outputs, but the type system enforces disciplined usage through typing judgments. Borrowing and references may be modeled as controlled, temporary relaxations of usage constraints, after which the original value must be returned or consumed.

Semantics and properties

Lineara emphasizes deterministic resource management and memory safety in theoretical models. By preventing unrestricted duplication and implicit garbage collection, lineara aims to reveal how program structure changes when resources are explicitly accounted for. The framework often highlights trade-offs between expressiveness and guarantees of absence of resource leaks or aliasing.

Relation to real concepts

Lineara borrows notions from linear type systems, linear logic, and ownership models in programming languages. It is typically discussed as a conceptual tool or teaching abstraction rather than a standardized, widely implemented language.
