Support doc blocks without leading asterisk

[chriskrycho]

There are two common styles of doc blocks in JS these days. The first is the one currently supported by docblockr:

/**
 * This is the current style.

 * @param foo Does a fun thing.
 * @return The result of this function.
 */
function bar(foo) {
   // ...
}

Another style seems increasingly common, however, and I very much prefer it:

/**
  This is the style used in e.g. Ember.js' docs.

  @param foo Does a fun thing.
  @return The result of this function
 */
function bar(foo) {
  // ...
}

I'd love to see support for this style, without the leading asterisks on every line. (If you point me to the relevant spot in the code, I'll even take a look at what it would take to add a setting for it.)

At least I can point you to the code:
The star is added in the DocBlockrAtom.prototype.create_snippet function in docblockr-worker.js L995.

Some Explanation:

• this.prefix is "*"
• out is an array with the lines. For example it could be ['@param {number} x','@return']
• snippet contains the comment which will be added
