Documentation

parse

Arguments

:: Stream s Identity Char

=> Parser s a

The parser to use

-> SourceName

Name of the source file

-> s

the stream to parse, usually a String

-> Either ParseError a

Parse from a stream given a parser, same as parse in Parsec. We can use this to parse expressions or statements alone, not just whole programs.

type Parser s a = ParsecT s ParserState Identity a

The parser type, parametrised by the stream type s and the return value a

expression :: Stream s Identity Char => Parser s (Expression SourcePos)

A parser that parses ECMAScript expressions

statement :: Stream s Identity Char => Parser s (Statement SourcePos)

The parser that parses a single ECMAScript statement

program :: Stream s Identity Char => Parser s (JavaScript SourcePos)

A parser that parses an ECMAScript program.

parseFromString

Arguments

:: String

JavaScript source to parse

-> Either ParseError (JavaScript SourcePos)

A convenience function that takes a String and tries to parse it as an ECMAScript program:

parseFromString = parse program ""

parseFromFile

Arguments

:: (Error e, MonadIO m, MonadError e m)

=> String

file name

-> m (JavaScript SourcePos)

A convenience function that takes a filename and tries to parse the file contents an ECMAScript program, it fails with an error message if it can't.

parseScriptFromString

Arguments

:: String

source file name

-> String

JavaScript source to parse

-> Either ParseError (JavaScript SourcePos)

Deprecated: Use parseFromString instead

Parse a JavaScript program from a string

parseJavaScriptFromFile

Arguments

:: MonadIO m

=> String

file name

-> m [Statement SourcePos]

Deprecated: Use parseFromFile instead

Read a JavaScript program from file an parse it into a list of statements

parseScript :: Stream s Identity Char => Parser s (JavaScript SourcePos)

Deprecated: Use program instead

parseExpression :: Stream s Identity Char => ExpressionParser s

Deprecated: Use expression instead

parseString

Arguments

:: String

JavaScript source

-> [Statement SourcePos]

Deprecated: Use parseFromString instead

Parse a JavaScript source string into a list of statements

type ParsedStatement = Statement SourcePos

assignExpr :: Stream s Identity Char => ExpressionParser s

Deprecated: Use expression instead
