+# quick-format-unescaped
+
+## unescaped ?
+
+Sometimes you want to embed the results of quick-format into another string, 
+and then escape the whole string. 
+
+## usage
+
+```js
+var format = require('quick-format-unescaped')
+format('hello %s %j %d', ['world', [{obj: true}, 4, {another: 'obj'}]])
+```
+
+## format(fmt, parameters, [options])
+
+### fmt
+
+A `printf`-like format string. Example: `'hello %s %j %d'`
+
+### parameters
+
+Array of values to be inserted into the `format` string. Example: `['world', {obj:true}]`
+
+### options.stringify
+
+Passing an options object as the third parameter with a `stringify` will mean 
+any objects will be passed to the supplied function instead of an the 
+internal `tryStringify` function. This can be useful when using augmented
+capability serializers such as [`fast-safe-stringify`](http://github.com/davidmarkclements/fast-safe-stringify) or [`fast-redact`](http://github.com/davidmarkclements/fast-redact).  
+
+## caveats
+
+By default `quick-format-unescaped` uses  `JSON.stringify` instead of `util.inspect`, this means functions *will not be serialized*.
