Rndr

Rndr is a small Ruby cli gem that provides a method of rendering discovered erb templates. Variables for use in template rendering can be used directly by providing a either a yaml or json file, or alternatively a directory may be supplied along with the variable merging strategy. Rndr supports both standard hash merges or recursive (default).

In addition to supporting recursive hash merges, additional hash control options may be passed via the --merge-opts hash directive. This supports the available options as supported by the deep_merge gem.

Paths can be ignored by either creating a .rndrignore file within the current working directly, or supplying a path to a desired ignore file.
