-// Acorn: Loose parser
-//
-// This module provides an alternative parser (`parse_dammit`) that
-// exposes that same interface as `parse`, but will try to parse
-// anything as JavaScript, repairing syntax error the best it can.
-// There are circumstances in which it will raise an error and give
-// up, but they are very rare. The resulting AST will be a mostly
-// valid JavaScript AST (as per the [Mozilla parser API][api], except
-// that:
-//
-// - Return outside functions is allowed
-//
-// - Label consistency (no conflicts, break only to existing labels)
-//   is not enforced.
-//
-// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
-//   the parser got too confused to return anything meaningful.
-//
-// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
-//
-// The expected use for this is to *first* try `acorn.parse`, and only
-// if that fails switch to `parse_dammit`. The loose parser might
-// parse badly indented code incorrectly, so **don't** use it as
-// your default parser.
-//
-// Quite a lot of acorn.js is duplicated here. The alternative was to
-// add a *lot* of extra cruft to that file, making it less readable
-// and slower. Copying and editing the code allowed me to make
-// invasive changes and simplifications without creating a complicated
-// tangle.

   - `"regenerator"` - transpile with [regenerator](https://github.com/facebook/regenerator). If regenerator is not installed, the exception will be thrown.
-  - a function - this function should accept the code of validation function as a string and return transpiled code. This option allows you to use any other transpiler you prefer.
+  - a function - this function should accept the code of validation function as a string and return transpiled code. This option allows you to use any other transpiler you prefer. If you are passing a function, you can simply pass it to `processCode` option without using ajv-async.
 
 
 ##### Advanced options
 
-- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). With option `v5: true` [v5 meta-schema](https://raw.githubusercontent.com/epoberezkin/ajv/master/lib/refs/json-schema-v5.json#) will be added as well. If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword.
+- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword.
 - _validateSchema_: validate added/compiled schemas against meta-schema (true by default). `$schema` property in the schema can either be http://json-schema.org/schema or http://json-schema.org/draft-04/schema or absent (draft-4 meta-schema will be used) or can be a reference to the schema previously added with `addMetaSchema` method. Option values:
   - `true` (default) -  if the validation fails, throw the exception.
   - `"log"` - if the validation fails, log error.
   - `false` - skip schema validation.
-- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `id` property that doesn't start with "#". If `id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `id` uniqueness check when these methods are used. This option does not affect `addSchema` method.
+- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `$id` (or `id`) property that doesn't start with "#". If `$id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `$id` uniqueness check when these methods are used. This option does not affect `addSchema` method.
 - _inlineRefs_: Affects compilation of referenced schemas. Option values:
   - `true` (default) - the referenced schemas that don't have refs in them are inlined, regardless of their size - that substantially improves performance at the cost of the bigger size of compiled schema functions.
   - `false` - to not inline referenced schemas (they will be compiled as separate functions).
   - integer number - to limit the maximum number of keywords of the schema that will be inlined.
 - _passContext_: pass validation context to custom keyword functions. If this option is `true` and you pass some context to the compiled validation function with `validate.call(context, data)`, the `context` will be available as `this` in your custom keywords. By default `this` is Ajv instance.
 - _loopRequired_: by default `required` keyword is compiled into a single expression (or a sequence of statements in `allErrors` mode). In case of a very large number of properties in this keyword it may result in a very big validation function. Pass integer to set the number of properties above which `required` keyword will be validated in a loop - smaller validation function size but also worse performance.
-- _ownProperties_: by default ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst.
+- _ownProperties_: by default Ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst.
 - _multipleOfPrecision_: by default `multipleOf` keyword is validated by comparing the result of division with parseInt() of that result. It works for dividers that are bigger than 1. For small dividers such as 0.01 the result of the division is usually not integer (even when it should be integer, see issue [#84](https://github.com/epoberezkin/ajv/issues/84)). If you need to use fractional dividers set this option to some positive integer N to have `multipleOf` validated using this formula: `Math.abs(Math.round(division) - division) < 1e-N` (it is slower but allows for float arithmetics deviations).
 - _errorDataPath_: set `dataPath` to point to 'object' (default) or to 'property' when validating keywords `required`, `additionalProperties` and `dependencies`.
-- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call).
 - _messages_: Include human-readable messages in errors. `true` by default. `false` can be passed when custom messages are used (e.g. with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n)).
-- _beautify_: format the generated function with [js-beautify](https://github.com/beautify-web/js-beautify) (the validating function is generated without line-breaks). `npm install js-beautify` to use this option. `true` or js-beautify options can be passed.
+- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call).
+- _processCode_: an optional function to process generated code before it is passed to Function constructor. It can be used to either beautify (the validating function is generated without line-breaks) or to transpile code. Starting from version 5.0.0 this option replaced options:
+  - `beautify` that formatted the generated function using [js-beautify](https://github.com/beautify-web/js-beautify). If you want to beautify the generated code pass `require('js-beautify').js_beautify`.
+  - `transpile` that transpiled asynchronous validation function. You can still use `transpile` option with [ajv-async](https://github.com/epoberezkin/ajv-async) package. See [Asynchronous validation](#asynchronous-validation) for more information. 
 - _cache_: an optional instance of cache to store compiled schemas using stable-stringified schema as a key. For example, set-associative cache [sacjs](https://github.com/epoberezkin/sacjs) can be used. If not passed then a simple hash is used which is good enough for the common use case (a limited number of statically defined schemas). Cache should have methods `put(key, value)`, `get(key)`, `del(key)` and `clear()`.
+- _serialize_: an optional function to serialize schema to cache key. Pass `false` to use schema itself as a key (e.g., if WeakMap used as a cache). By default [json-stable-stringify](https://github.com/substack/json-stable-stringify) is used.
 
 
 ## Validation errors
 
-In case of validation failure Ajv assigns the array of errors to `.errors` property of validation function (or to `.errors` property of Ajv instance in case `validate` or `validateSchema` methods were called). In case of [asynchronous validation](#asynchronous-validation) the returned promise is rejected with the exception of the class `Ajv.ValidationError` that has `.errors` poperty.
