Usage¶ ↑

Downlow is comprised of two main features: Fetchers and Extractors. They do what they sound like they do.

To just fetch a remote (or local file or directory)

Downlow::Fetcher.fetch('remote', :destination => 'local')

Fetcher currently handles these styles of URL

Git (git://)
HTTP (http://)
Github (gh://user/project)
Local (anything else)

Extractors take a local file, and extract them based on their extension:

Downlow::Extractor.extract('local.archive', :destination => 'directory')

The extractors currently supported are

.tar.gz
.zip
dir (everything else)

DL() is just an alias for Downlow.get() which is just a wrapper around .fetch() and then .extract()

Thanks¶ ↑

Thanks to @mxcl for the awesome pathname extensions in homebrew/ Thanks to @defunkt as I took some ideas from rip.

Note on Patches/Pull Requests¶ ↑

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don’t break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
