/**
|
|
* Main class of Peast library.
|
|
* Every function of this class takes two arguments:
|
|
* - The source code to parse
|
|
* - The options array that is an associative array of parser settings.
|
|
* Available options are:
|
|
* - "sourceType": one of the source type constants declared in this class.
|
|
* This option tells the parser to parse the source in script or module
|
|
* mode. If this option is not provided the parser will work in script
|
|
* mode.
|
|
* - "sourceEncoding": the encoding of the source. If not specified the
|
|
* parser will assume UTF-8.
|
|
* - "strictEncoding": if false the parser will handle invalid UTF8
|
|
* characters in the source code by replacing them with the character
|
|
* defined in the "mbstring.substitute_character" ini setting, otherwise
|
|
* it will throw an exception.
|
|
* - "comments": if true it enables comments parsing.
|
|
* - "jsx": if true it enables parsing of JSX syntax.
|
