CountDownLatch is a synchronization aid that allows one or more threads to wait until a set of operations being performed in other threads completes.

Slop provides a Ruby domain specific language for gathering options and parsing command line flags.

ChunkyPNG is a pure Ruby library that can read and write Portable Network Graphics (PNG) images without depending on an external image library. It tries to be memory efficient and reasonably fast. It has features such as:

• Decoding support for any image that the PNG standard allows. This includes all standard color modes, all bit depths, all transparency, and interlacing and filtering options.

• Encoding support for images of all color modes (true color, grayscale, and indexed) and transparency for all these color modes. The best color mode is chosen automatically, based on the amount of used colors.

• Read/write access to the image's pixels.

• Read/write access to all image metadata that is stored in chunks.

• Memory efficiency: fixnum are used, i.e. 4 or 8 bytes of memory per pixel, depending on the hardware).

• Performance: ChunkyPNG is reasonably fast for Ruby standards, by only using integer math and a highly optimized saving routine.

• Interoperability with RMagick.

ChunkyPNG is vulnerable to decompression bombs and can run out of memory when loading a specifically crafted PNG file. This is hard to fix in pure Ruby. Deal with untrusted images in a separate process, e.g., by using fork or a background processing library.

This package provides a implementations of custom cops that are bundled as defaults in Standard Ruby.

This gem is a Faraday adapter for the Net::HTTP library. Faraday is an HTTP client library that provides a common interface over many adapters.

Net::SFTP is a pure Ruby implementation of the SFTP protocol (specifically, versions 1 through 6 of the SFTP protocol). Note that this is the “Secure File Transfer Protocol”, typically run over an SSH connection, and has nothing to do with the FTP protocol.

Fuubar is an RSpec formatter that uses a progress bar instead of a string of letters and dots as feedback. It also stops on the first test failure.

Saikuro is a Ruby cyclomatic complexity analyzer. When given Ruby source code Saikuro will generate a report listing the cyclomatic complexity of each method found. In addition, Saikuro counts the number of lines per method and can generate a listing of the number of tokens on each line of code.

Octokit wraps the GitHub API in a flat API client that follows Ruby conventions and requires little knowledge of REST.
