Want to contribute?

If you find a bug, have any questions or want to contribute. Be sure to file an issue with the appropiate tag.

If submitting a bug fix or a new component, please send those into develop currently.

The develop branch is where we are working on all the new features. It is currently highly experimental and no support building or using it will be provided.

Usage

Command line:

 # reads xml file and prints it in yml
 $ bin/cop --yml examples/setting.xml

 # reads directory of inputs and prints it in yml
 $ bin/cop --yaml examples/

 # reads yaml and prints it in json
 $ bin/cop examples/setting.yml --json

 # reads shell VARs and prints it in json
 $ bin/cop examples/shell.vars --json

 # Accepts multiple inputs
 $ bin/cop --json examples/setting.json examples/setting.yml

 # Renders and compile templates to STDOUT
 $ bin/cop --render-template examples/views/Dockerfile.hbs examples/setting.json examples/setting.yml

 # Accept configuration input from STDIN
 $ curl https://raw.githubusercontent.com/jasmith590/COP/develop/examples/setting.yml | bin/cop --shell --stdin-type=yaml
 $ echo "defaults__from=\"apline\"" | bin/cop -t examples/views/Dockerfile.hbs --stdin-type=shell

 # Accept template input from STDIN
 $ curl https://raw.githubusercontent.com/jasmith590/COP/develop/examples/views/Dockerfile.hbs | bin/cop --stdin-type=hbs examples/setting.json

 # Using Regex patterns for filtering root level configurations
 $ bin/cop examples/settings01.yml examples/settings02.yml --yml --filter='^(?!test)'

Within your program:

var cop = require('cop.js');

# Load yaml
var doc = cop.gatherInputs('setting.yml');

# Load multiple files
var doc = cop.gatherInputs(['setting.yml', 'setting.xml']);

# print doc in yaml
console.log(cop.format.yaml.stringify(doc));

STDIN Support

In order to allow better STDIN support, a prefix enviroment variable has been added. In order to use:

$ export COP_PREFIX="config__"
$ curl https://api.github.com/repos/jasmith590/COP/tags | bin/cop --shell --stdin-type=json

What does this do? This allows you to add a prefix to the output formats. For example, if you have a preset of "config__", then this will turn into the below:

config__0__name="0.3.0"
config__0__zipball_url="https://api.github.com/repos/jasmith590/COP/zipball/0.3.0"
config__0__tarball_url="https://api.github.com/repos/jasmith590/COP/tarball/0.3.0"
config__0__commit__sha="726e1994e98df36c1058166ddc8802624cf3f5bd"
config__0__commit__url="https://api.github.com/repos/jasmith590/COP/commits/726e1994e98df36c1058166ddc8802624cf3f5bd"
config__1__name="0.2.0"
config__1__zipball_url="https://api.github.com/repos/jasmith590/COP/zipball/0.2.0"
config__1__tarball_url="https://api.github.com/repos/jasmith590/COP/tarball/0.2.0"
config__1__commit__sha="0c42fad98ed0ebb6ee987d1e5611fc045ed73f52"
config__1__commit__url="https://api.github.com/repos/jasmith590/COP/commits/0c42fad98ed0ebb6ee987d1e5611fc045ed73f52"

Test cases

To execute full test cases

$ make test

Adding Rendering Engines

Adding another rendering engine requires two main things

First edit the file template.js. Add the extension and filename.

// Main template typecasting
var templateEngines = {
  dust: ['dust'],
  handlebars: ['hbs','handlebars'],
  marko: ['marko'],
  nunjucks: ['njk','nunjucks', 'j2', 'jinja', 'jinja2']
};

The add your rendering module within views. For an example of a template module, view this file

##Requirements

• Node.js v6.0.0 or newer

##Feature Requests If you find COP doesn't support or contain a particular component you think would be useful, please check all the current issues in case someone else requested it first. If not, you can request a new feature by creating an issue on the repo itself.
