* ```ts
|
|
* type Session = peg.compiler.Session;
|
|
* type Pass = ( ast: {}, session: Session, options: {} ) => void;
|
|
* type StageMap = { [string]: { [string]: Pass } };
|
|
* type PassMap = { [string]: Pass[] };
|
|
* ```
|
|
*
|
|
* The PEG.js compiler runs each `Pass` on the `PassMap` (the `passes` option on it's 2nd
|
|
* argument), but the compiler api exposes a `StageMap` so that it is easier for plugin
|
|
* developer's to access the built-in passes.
|
|
*
|
|
* This method takes a `StageMap`, returning a `PassMap` that can be used by the compiler.
