# nearley-unparse
[](https://travis-ci.org/smallhelm/nearley-unparse)
JavaScript API to "unparse" any nearley grammar. Also allows overrides for given grammar rules.
```js
var unparse = require("nearley-unparse");
//somehow import your compiled grammar
var grammar = require("./grammar");
var src = unparse(grammar);
//BAM! Now you have generated some src that will parse.
```
## API
### src = unparse(grammar[, options])
* `options.start` which rule to start the unparser. (default: `grammar.ParserStart`)
* `options.override_rule` a map where the keys are the rule name and the value is a function that returns a string for that rule.
* `options.filterRule` a function that will take in a rule and return true if it should be selected. This is handy when you want to exclude rules like paren wrapping so it doesn't just output something like this: `(((((1)))))`
* `options.max_stack_size` useful to limit how deeply nested rules are. (default: 25)
* `options.max_loops` useful to keep it from running "forever". (default: 500)
