history
Project history and usage
nicovideo-dl is a command-line program for downloading videos from www.nicovideo.jp.
Project history
Homebrew packages version 0.0.20190126 from an OSDN release archive and identifies the OSDN project page as the homepage. The formula has been patched by Homebrew for newer Python compatibility, which is typical of small site-specific downloader scripts after upstream activity slows.
Adoption history
The package has very small Homebrew usage: the July 2026 API reports zero installs over 30 and 90 days and five installs over 365 days. Homebrew marks the formula deprecated on 2025-10-23 because the repository was removed and schedules disablement for 2026-10-23.
How it is used
Users run `nicovideo-dl` against one or more Niconico video URLs. The official package metadata identifies it as a Python-backed command-line downloader for www.nicovideo.jp.
Why package nerds care
nicovideo-dl is significant mainly as a legacy package-manager artifact: a narrow video-site downloader whose upstream repository disappeared while the package manager continued to carry a patched historical release for users who still had scripts depending on it.
