Kojo - Configuration Ninja ================================================== [](https://badge.fury.io/rb/kojo) [](https://travis-ci.com/DannyBen/kojo) [](https://codeclimate.com/github/DannyBen/kojo/maintainability) Kojo helps you generate configuration files from templates, using variables and definition files. It is a command line utility, and it works on any text file format.

---

Installation

$ gem install kojo

Usage

If you prefer to learn by example, see the examples folder for several use cases. Each example subfolder contains the command to run, the relevant files, and the expected output.

Variables

Include variables in your configuration templates using this syntax:

%{varname}

• Variables can be provided through the command line, or when using @import.
• Variables from the top level will be forwarded downstream, and aggregated with any additional variables that are defined in subsequent @imports.

Import

Use the @import filename directive anywhere to include another file in the resulting configuration file.

• The @import directive should be the only thing in the line.
• The indentation will be respected when importing.
• The filename parameter does not have to include an extension - Kojo will use the same extension as the parent file.
• The included file will be searched for relative to the file it is included in.
• Arguments can be passed down to the included template by using this syntax:

@import filename (arg: "value", arg2: "value")

The space after filename is optional.

One to Many Generation

In order to generate several configuration files that are based on the same template, you should:

1. Create the configuration template, using %{variables} and @imports where appropriate.
2. Create a configuration YAML file using this syntax:

input: base-template.yml

output:
  outfile1.yml:
    argument1: value
    argument2: value

  outfile2.yml:
    argument1: value
    argument2: value

Compile an Entire Folder

Process a folder containing templates and @imports, and generate a mirror output folder, with all the variables and @imports evaluated.
