## プロジェクトの歴史と使われ方

libversion is Repology's C library for comparing messy software version strings, including prerelease markers, suffixes, separators, and package-repository conventions that simple lexical comparison gets wrong.

### プロジェクトの歴史

The library was written by Dmitry Marakasov for the Repology ecosystem. Its README frames the core problem as comparing versions from different package repositories, where strings such as alpha, beta, rc, patch, post, and unusual separators need stable ordering rules.

### 採用の歴史

libversion is used by Repology itself, and Repology's updater lists the Python libversion module, the C library, and a PostgreSQL libversion extension among its dependencies. That makes the library part of the machinery behind cross-distribution version tracking rather than a general end-user command.

### 使われ方

The library exposes C comparison functions, installs pkg-config and CMake integration files, and includes command-line utilities such as version_compare and version_sort for package-maintainer scripts or quick checks.

### パッケージ好きにとっての重要性

Version ordering is one of the oldest package-manager traps. libversion is interesting because it treats packaging reality as the problem domain: upstreams encode prereleases, patches, and suffixes inconsistently, and repository comparison services need deterministic answers.

### タイムライン

- 1.0.0: First tagged major release line in the public repository.
- 2.0.0: Later tagged major release line in the public repository.
- 3.0.0: Later tagged major release line in the public repository.

### Related projects

- Repology uses libversion for software-version comparison across repositories.
- py-libversion, libversion-rs, golibversion, ruby-libversion, and other bindings or compatible implementations extend the same comparison model.
