# Parsing

parse

Arguments

:: String | The input stream (Javascript source code).
-> String | The name of the Javascript source (filename or input device).
-> Either String JSAST | An error or maybe the abstract syntax tree (AST) of zero or more Javascript statements, plus comments.

Parse one compound statement, or a sequence of simple statements. Generally used for interactive input, such as from the command line of an interpreter. Return comments in addition to the parsed statements.

readJs :: String -> JSAST

parseFile :: FilePath -> IO JSAST

Parse the given file. For UTF-8 support, make sure your locale is set such that "System.IO.localeEncoding" returns "utf8"

parseFileUtf8 :: FilePath -> IO JSAST

Parse the given file, explicitly setting the encoding to UTF8 when reading it
