multiline chainable methods about coffeescript HOT 7 CLOSED

His example actually puts each property access on a newline -- markdown fail.

from coffeescript.

CoffeeScript already supports this -- you just need to end the line with the dot operator, instead of beginning it, indicating to the parser that the line isn't finished. (No semicolons, folks). Currently, this:

$(".team").
  find("player").
  animate("slow").
  highlight().
  css("color","#ff0000")

Compiles into:

$(".team").find("player").animate("slow").highlight().css("color", "#ff0000");

i try but i give this error:
line 1: syntax error for '.'

i use the gem version. should be this the problem. thanks

from coffeescript.

Yes. The gem is pretty far behind at this point -- I don't want to push out a new one until CoffeeScript 0.2.0, which includes significant whitespace, along with a host of other improvements (ideally later today).

For now, you can checkout the source (master branch), and run rake gem:install to build yourself a fresher version of CoffeeScript.

Is there a particular reason that CS can't support

$(".team")
  .find("player")
  .css("top")

It's a preferable style, as otherwise the notion of the function call is separated over two lines.

from coffeescript.

Alright weepy, francesco --

jQuery-style multiline calls are now possible on master. Weepy's last example compiles into this:

$(".team").find("player").css("top");

The lexer just needs to peek at the next character, before it decides to tokenize a newline.

Wooop!
