module Language.Javascript.JMacro.Prelude

-- | This provides a set of basic functional programming primitives, a few
--   utility functions and, more importantly, a decent sample of idiomatic
--   jmacro code. View the source for details.
jmPrelude :: JStat

-- | Simple DSL for lightweight (untyped) programmatic generation of
--   Javascript.
--   
--   A number of examples are available in the source of
--   Language.Javascript.JMacro.Prelude.
--   
--   Functions to generate generic RPC wrappers (using json serialization)
--   are available in Language.Javascript.JMacro.Rpc.
--   
--   usage:
--   
--   
--   renderJs [jmacro|fun id x -> x|]
--   
--   
--   The above produces the id function at the top level.
--   
--   
--   renderJs [jmacro|var id = \x -> x;|]
--   
--   
--   So does the above here. However, as id is brought into scope by the
--   keyword var, you do not get a variable named id in the generated
--   javascript, but a variable with an arbitrary unique identifier.
--   
--   
--   renderJs [jmacro|var !id = \x -> x;|]
--   
--   
--   The above, by using the bang special form in a var declaration,
--   produces a variable that really is named id.
--   
--   
--   renderJs [jmacro|function id(x) {return x;}|]
--   
--   
--   The above is also id.
--   
--   
--   renderJs [jmacro|function !id(x) {return x;}|]
--   
--   
--   As is the above (with the correct name).
--   
--   
--   renderJs [jmacro|fun id x {return x;}|]
--   
--   
--   As is the above.
--   
--   
--   renderJs [jmacroE|foo(x,y)|]
--   
--   
--   The above is an expression representing the application of foo to x
--   and y.
--   
--   
--   renderJs [jmacroE|foo x y|]]
--   
--   
--   As is the above.
--   
--   
--   renderJs [jmacroE|foo (x,y)|]
--   
--   
--   While the above is an error. (i.e. standard javascript function
--   application cannot seperate the leading parenthesis of the argument
--   from the function being applied)
--   
--   
--   \x -> [jmacroE|foo `(x)`|]
--   
--   
--   The above is a haskell expression that provides a function that takes
--   an x, and yields an expression representing the application of foo to
--   the value of x as transformed to a Javascript expression.
--   
--   
--   [jmacroE|\x ->`(foo x)`|]
--   
--   
--   Meanwhile, the above lambda is in Javascript, and brings the variable
--   into scope both in javascript and in the enclosed antiquotes. The
--   expression is a Javascript function that takes an x, and yields an
--   expression produced by the application of the Haskell function foo as
--   applied to the identifier x (which is of type JExpr -- i.e. a
--   Javascript expression).
--   
--   Other than that, the language is essentially Javascript (1.5). Note
--   however that one must use semicolons in a principled fashion -- i.e.
--   to end statements consistently. Otherwise, the parser will mistake the
--   whitespace for a whitespace application, and odd things will occur. A
--   further gotcha exists in regex literals, whicch cannot begin with a
--   space. x  5  4 parses as ((x  5)  4). However,
--   x 5  4 will parse as x(5 , 4). Such are the
--   perils of operators used as delimeters in the presence of whitespace
--   application.
--   
--   Additional features in jmacro (documented on the wiki) include an
--   infix application operator, and an enhanced destructuring bind.
--   
--   Additional datatypes can be marshalled to Javascript by proper
--   instance declarations for the ToJExpr class.
--   
--   An experimental typechecker is available in the
--   Language.Javascript.JMacro.Typed module.
