Was just looking for the same, here's a basic Javascript-based YAML parser written by Tj Holowaychuk over at refactormycode.com. I'm duplicating it here to ensure it isn't lost, appears the JsYaml link on yaml.org has been broken a while. Haven't tested it yet.
;(function(){
YAML = {
valueOf: function(token) {
return eval('(' + token + ')')
},
tokenize: function(str) {
return str.match(/(---|true|false|null|#(.*)|\[(.*?)\]|\{(.*?)\}|[\w\-]+:|-(.+)|\d+\.\d+|\d+|\n+)/g)
},
strip: function(str) {
return str.replace(/^\s*|\s*$/, '')
},
parse: function(tokens) {
var token, list = /^-(.*)/, key = /^([\w\-]+):/, stack = {}
while (token = tokens.shift())
if (token[0] == '#' || token == '---' || token == "\n")
continue
else if (key.exec(token) && tokens[0] == "\n")
stack[RegExp.$1] = this.parse(tokens)
else if (key.exec(token))
stack[RegExp.$1] = this.valueOf(tokens.shift())
else if (list.exec(token))
(stack.constructor == Array ?
stack : (stack = [])).push(this.strip(RegExp.$1))
return stack
},
eval: function(str) {
return this.parse(this.tokenize(str))
}
}
})()
print(YAML.eval(readFile('config.yml')).toSource())
// config.yml
