Exek

Comprehensive tools to start and run commands.

Most existing gems that address command execution provide a limited interface or lack notable features. In contast, Exek seeks to provide comprehensive support for all of a program's exec needs with one thoughtfully-designed library.

Intended features:

• A "Command" class that encapsulates argv, env, and IO options, and process state.
• Easy-to-use high level interfaces with sensible defaults for running commands to completion.
• Comprehensive support for low-level concerns like piping, PTYs, and file descriptor magic.
• Utilities for manipulating sh script strings, idiomatically building argument arrays, and generating reusable interaces for common system commands.
• Tracing and introspection facilities for logging and latency analysis.
• Safety: does not monkeypatch external modules, encourage mixins or use eval. Attempts to guide developers away from unsafe practices like shell scripts and shell injection.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
