RubyGems

Mode: 🌐 Public · Domain: rubygems.org

Search and inspect Ruby gems on the public RubyGems.org index without auth or browser. Two commands cover discovery and per-gem metadata.

Commands

Command	Description
opencli rubygems search <query>	Search RubyGems.org gems by keyword
opencli rubygems gem <name>	Single-gem metadata (version, downloads, license, links)

Usage Examples

# Search gems
opencli rubygems search rails --limit 10
opencli rubygems search redis --limit 5

# Single-gem metadata (use `gem` from search rows)
opencli rubygems gem rails
opencli rubygems gem sidekiq

# JSON output
opencli rubygems search rails -f json
opencli rubygems gem rails -f json

Output Columns

Command	Columns
search	rank, gem, version, downloads, license, authors, info, url
gem	gem, version, releasedAt, downloads, versionDownloads, license, authors, homepage, source, bugs, info, url

The gem column from search round-trips into gem exactly.

Options

rubygems search

Option	Description
query (positional)	Search keyword
--limit	Max gems (1-100, default: 30)

rubygems gem

Option	Description
name (positional)	Gem name (rails, sidekiq, pundit)

Caveats

• Gem names are validated against RubyGems' own [A-Za-z0-9][A-Za-z0-9._-]* pattern (max 100 chars). Bad input raises ArgumentError.
• releasedAt is normalized to second-precision YYYY-MM-DDTHH:MM:SSZ.
• RubyGems throttles bursts; HTTP 429 surfaces as a typed CommandExecutionError with a retry hint.

Prerequisites

• No browser required — uses rubygems.org/api/v1/search.json and rubygems.org/api/v1/gems/<name>.json.
