CMake is used to control the software compilation process using simple platform and compiler independent configuration files. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice. CMake is quite sophisticated: it is possible to support complex environments requiring system configuration, pre-processor generation, code generation, and template instantiation.

Polyamorous is an extraction of shared code from the Active Record Hackery gems Ransack, Squeel and MetaSearch by Ernie Miller and maintained by Ryan Bigg, Xiang Li, Jon Atack and a great little group of contributors. It is an internal library for extending various versions of Active Record with polymorphism. There is no public API, so it's :nodoc:. Move along. Nothing to see here.

Violet is a UML editor with these benefits: * It is very easy to learn and use * It draws nice-looking class, sequence, state, object and use-case diagrams * It is completely free (distributed under the GNU General Public License) * It is cross-platform Violet is intended for students, teachers, and authors who need to produce simple UML diagrams quickly. It is not intended as an industrial strength tool. Here are some of the features that industrial-strength UML programs have and that Violet does not have: * Code generation. Violet does not generate any source code from UML diagrams. * Reverse engineering. Violet does not generate UML diagrams from source code * Semantic checking of models. You can use Violet to draw contradictory diagrams XMI export or import. Violet does not generate files that can be imported into other UML tools, nor can it read model files from other tools If you just want to draw simple UML diagrams without too much fuss, chances are you'll like Violet. If you have more serious needs, check out one of the other programs.

Polyglot provides a registry of file types that can be loaded by calling its improved version of 'require'. Each file extension that can be handled by a custom loader is registered by calling Polyglot.register('ext', <class>), and then you can simply require 'somefile', which will find and load 'somefile.ext' using your custom loader. This supports the creation of DSLs having a syntax that is most appropriate to their purpose, instead of abusing the Ruby syntax. Required files are attempted first using the normal Ruby loader, and if that fails, Polyglot conducts a search for a file having a supported extension.

POpen4 provides the Rubyist a single API across platforms for executing a command in a child process with handles on stdout, stderr, stdin streams as well as access to the process ID and exit status. RG: https://rubygems.org/gems/POpen4
