Store sensitive data safely as encrypted strings or entire files, using symmetric aes-256-cbc encryption/decryption with a secret key and an IV vector, and YAML-friendly base64-encoded encrypted result.

This is an Arduino helper toolkit that builds on top of the arduino-cmake project — a powerful alternative build system for Arduino. What Arli provides is capability to search for libraries by any attributes and regular expressions, install a whole set of libraries defined in a YAML file Arlifile, and finally, it can generate a brand new Sketch Project based on arduino-cmake, that builds out the box. Arli is a command line tool, so run "arli" after installing the gem for more information.

BoxBot aims to generate an SVG or PDF template that is meant to be used with a laser cutter. Boxbot will generate a 2D cut layout for a 3D box (parallelepiped) with matching tabs that allow the box to be "snapped into place" without screws, although screws and T-joins can also be added. This gem is currently work in progress, and is a rewrite of the laser-cutter box drawing logic.

This gem's purpose in life is to freely convert various configurations between supported formats, which are currently YAML, JSON and Windows INI file format. The gem is named after a popular package supervisord, which uses INI file format for it's configuration. This gem will allow you to move supervisord configuration into a YAML file, and integrate with other DevOps tools, while generating INI file on the fly. When installed, library exposes 'dv' executable, which is a an easy-to-use converter between these three formats.

Molder is a handy command line tool for generating and running (in parallel, using a pool of processes with a configurable size) a set of related and yet different commands. A YAML file defines both the attributes and the command template, and Molder then merges the two with CLI arguments to give you a consistent set of commands for, eg. provisioning thousands of virtual hosts in a cloud. The gem is not limnited to any particular cloud, tool, or a command, and can be used across various domains to generate a consistent set of commands based on the YAML-supplied attributes and templates, that might vary across custom dimensions. For example, you could generate 600 provisioning commands for hosts in EC2, numbered from 1 to 100, but constrained to the zones "a", "b", "c", and data centers "dc" (values: ['us-west2', 'us-east1' ]). Behind the scenes Molder uses another Ruby gem Parallel — for actually running the provisioning commands.
