Install

TODO: talk about balrog integration

$ npm install balrog-meta-htmlcomment

Usage

TODO: talk about balrog usage

var extract = require('balrog-meta-htmlcomment')

extract(content)

content should be either a string or a buffer. If it is a buffer, it will be converted to a string with .toString('utf8').

It's expected that the first non-whitspace string in content is <!-- on its own line. Every line after that will be treated like a <key>:<value> pair. Any whitespace at the beginning and end of the line will be trimmed, as well as any whitespace before and after the “:”.

A “tags” key will be represented in the metadata as an array, using the comma character (and any leading/trailing whitespace) as the separator to split the string. So something like tags: hey, you, guys would be represented as ['hey', 'you', 'guys'].
