ThisVersionOf

ThisVersionOf is a placeholder name used in software development and content management to denote the currently selected version of a resource, such as a library, document, or dataset. It is not a standardized keyword, but a conventional identifier that appears in templates, scripts, and documentation to enable dynamic versioning and version-aware content.

In templating and build systems, thisVersionOf may be resolved at render or build time to the version string of the target artifact. For example, a template might include a field such as version: thisVersionOf('libraryX'), which during processing expands to a concrete version like '1.4.2'. In file naming or metadata, it can serve to reference the active version so artifacts produced from the same template differ by version, facilitating reproducibility and traceability.

Implementation patterns vary. A project can implement thisVersionOf as a function or macro that returns a version from a version matrix, a lockfile, or a configuration source. It may be defined in code, a configuration file, or within a templating engine, and then consumed wherever version information is needed, such as documentation, release notes, or deployment manifests.

Limitations and considerations include the lack of a universal standard for thisVersionOf. Different systems may use different syntax or casing, and ambiguous scope can lead to incorrect version resolution. Clear documentation and consistent usage within a project help mitigate these issues. See also versioning, semantic versioning, and templating practices.
