## プロジェクトの歴史と使われ方

nvchecker is a Python tool for checking whether new upstream software versions have been released. Its README and documentation define the 2.x branch as the active TOML-configured line, with helper commands such as `nvtake`, `nvcmp`, `nvchecker-notify`, and `nvchecker-ini2toml` around version-record workflows.

### プロジェクトの歴史

nvchecker comes from lilydjwg and the Arch-oriented packaging world. An Arch Linux CN wiki page from 2015 recommends it to package maintainers for keeping repository packages up to date, while the upstream documentation records a 1.x-to-2.x transition that changed command syntax, moved configuration from INI to TOML, made source selection explicit, and switched version record files to JSON.

### 採用の歴史

The adoption pattern is strongest among distribution and repository maintainers. Arch Linux packages nvchecker in Extra, Arch Linux CN documents it for repo maintenance, Homebrew ships it for macOS/Linux users, and the docs include source backends for GitHub, GitLab, PyPI, NPM, crates.io, Debian, Ubuntu, Repology, Anitya, container registries, and more. Homebrew analytics on 2026-07-01 showed 251 installs over 365 days, which understates usage in Linux packaging automation.

### 使われ方

A maintainer writes a TOML file with one table per watched project and a `source` such as GitHub, PyPI, NPM, regex, Debian, or Repology, then runs `nvchecker -c config_file.toml`. nvchecker writes or compares JSON version records; `nvcmp` reports differences between old and new records, and `nvtake` marks selected updates as processed.

### パッケージ好きにとっての重要性

nvchecker is package-maintainer glue: it does not build packages, but it turns dozens of upstream release surfaces into a consistent update signal that can feed bots, CI jobs, or human review queues.

### タイムライン

- 2015-07-24: Arch Linux CN wiki documentation recommends nvchecker for package maintainers.
- 2.x branch: upstream documentation records the TOML configuration format, explicit source plugins, and JSON version-record workflow.
- 2026-07-01: Homebrew lists nvchecker 2.20 revision 2.
