    Pry

    Pry

    A runtime developer console and IRB alternative

    ...Features like show-source and show-doc reveal the implementation or documentation of methods without leaving the console, while edit-method lets you jump into an editor, modify code, and reload it on the fly. Dropping binding.pry into application code creates interactive breakpoints, making it easy to poke at variables, step through logic (with plugins like pry-byebug), and test hypotheses. An extensible command system and a rich plugin ecosystem add profiling, colorized output, paging, and Git integration. In day-to-day development, Pry shortens the feedback loop and turns debugging into an exploratory, conversational workflow.

    GitHub Markup

    GitHub Markup

    Determines which markup library to use to render a content file

    This library is the first step of a journey that every markup file in a repository goes on before it is rendered on GitHub.com. GitHub-markup selects an underlying library to convert the raw markup to HTML. See the list of supported markup formats provided. The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes. Syntax highlighting is performed on code blocks. See github/linguist for more information...

    Pro Git 2nd Edition

    ...All content is licensed under the Creative Commons Attribution Non Commercial Share Alike 3.0 license. Print versions of the book are available on Amazon.com. What is “version control”, and why should you care? Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. For the examples in this book, you will use software source code as the files being version controlled, though in reality you can do this with nearly any type of file on a computer. If you are a graphic or web designer and want to keep every version of an image or layout (which you would most certainly want to), a Version Control System (VCS) is a very wise thing to use.

    Puma

    Puma

    A Ruby/Rack web server built for concurrency

    Unlike other Ruby Webservers, Puma was built for speed and parallelism. Puma is a small library that provides a very fast and concurrent HTTP 1.1 server for Ruby web applications. It is designed for running Rack apps only. What makes Puma so fast is the careful use of a Ragel extension to provide fast, accurate HTTP 1.1 protocol parsing. This makes the server scream without too many portability issues. If you are using Bundler, just add Puma to your project's Gemfile. Once you've installed...

It supports specifying execution...

As of 2022_11 this "branch" of the wappskafander_t2 will not be incrementally updated, because it, the wrapping code, NOT the wrapped web server, is an old mess that needs a total rewrite.

Its client regularly gathers system facts, evaluates policy, and enforces drift correction, which makes environments reproducible from bare metal to cloud instances and containers. ...
