valib

Valib is a name frequently used for software libraries, tools, and small projects across programming communities. The term is often a contraction of "validation library" or "value library," and is not tied to a single canonical project; multiple independent repositories and packages with the same or similar names exist in different ecosystems.

As a concept, valib typically denotes a lightweight collection of utilities for data validation, type checking, parsing, or value manipulation. Implementations vary by language and scope: some valib projects focus on declarative data-schema validation for JSON or form input, others provide helper routines for numeric or string conversions, and a few serve as convenience wrappers around standard library functions.

Common characteristics include simple APIs, small dependency footprints, and an emphasis on runtime checks and clear error messages. Many valib-style libraries support chaining or composable validators, allow custom rule definitions, and integrate with application frameworks or testing tools.

Because "valib" is used by unrelated projects, users should consult package registries, source repositories, and documentation to verify features, compatibility, and licensing for a particular implementation. Licensing varies widely; popular choices include permissive open-source licenses and more restrictive terms depending on the maintainer.

In discussions, clarifying the target platform and repository URL helps disambiguate which valib is meant. The name exemplifies a common naming pattern in software: concise, descriptive labels that are reused in diverse contexts.
