Can't load YAML file with multiple documents

[lufego]

The problem

When trying to load a file with many documents, I get the following error:

Module Error (from ./node_modules/yaml-loader/index.js): expected a single document in the stream, but found more

The YAML file looks like something like this:

---
kind: example
apiVersion: v1
name: test
---
kind: example2
apiVersion: v1
name: test2
---
kind: example3
apiVersion: v1
name: test3

The solution

Ideally, I'd add a checker to count the documents, and if length > 1, then I'd invoke the safeLoadAll method instead of safeLoad. But since js-yaml doesn't export this counter function, would it be possible to replace safeLoad to safeLoadAll? I've tested and it would load both single and multiple documents in a file.

The change

module.exports = function (source) {
  this.cacheable && this.cacheable();
  try {
    var res = yaml.safeLoadAll(source);  
    return JSON.stringify(res, undefined, '\t');
  }
  catch (err) {
    this.emitError(err);
    return null;
  }
};

Unfortunately I don’t have time to maintain this package. Would you be interested in taking over it?

To your proposition: yeah make sense to me.

I added a new option for this, asStream.
