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. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### Related projects - Arch Linux CN lilac - Repology - Anitya - Renovate ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
