multi line coffeescipt in <% ... %>

[sircambridge]

being able to have multiple line coffeescript execute within <% %> would be awesome.

in erb and ejs, you can say

<%
  def something(arg)
    ...
  end
%>

or

<%
 function(){
 ...
}
%>

is there a workaround / somewhere i can hack this in ?

I've wondered this as well. Or is it intentionally so, to prevent complex templating?

[ckihneman]

+1. This would be a great feature, maybe it needs a special syntax of its own to trigger on so it knows indentation now matters...

<%*
    someVar = @something
    if someVar
      # do other stuff
*%>

Or something like that. I switched to eco from jQote2 and this is the only thing really giving me a large amount of frustration. Logic-less templates just are not in my cards for the project im on...

I made it work by wrapping everything in a <% someVar = @something %> for every line (and added : for any ifs/whatnot) - which is for sure not optimal when a couple lines of coffeescript do a lot better.

Thanks.

+1, I've wanted to do:

<%-
    data = @require('util').inspect @documentModel.getAttributes()
    delete data.fullPath
    delete data.outPath
    data
%>

but can't figure out how

As I use Eco, I'm getting a little bit torn on this, actually. I think it would encourage cluttery awful views, which would be bad, and my templates have actually been improved through this limitation. But at the same time, hashes would seem more acceptable to have multiline. They're essentially declarative, and can be quire useful.

For example, look at this formbuilder becomes frustrating to work with on a single line, (the alternative, assigning each argument to a variable, is also frustrating).

    <%- @select 'param_name', ['New York', 'San Francisco'], {class: 'my_class input-small', data: {toggle: 'dropdown'}, title: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit'} %>

hmm. thoughts?

+1, this is really needed.

I try to keep my code to 80 chars wide, so I need to be able to start a new line. It looks awful when every line begins with <% for no reason.

Definitely interested in this too, especially for "declarative" sections, like hashes, arrays...

Trying to do heredoc statements for multi-line variables but finding it impossible with eco.

Seems a developers has gone awol again. First coffeekup, now this?

I'd be happy to code in the changes myself though it's a little awkward putting time into a issue-accumulating repository. Where you at stephenson? :)

(For reference, issues #13 and #15. Not sure if anything has changed.)

But FWIW, @malgorithms's Toffee is an excellent alternative to Eco and supports multi-line blocks:

If someone wants to try to add this to Eco, I'd be happy to share the experiences I had making it work with Toffee. It was kind of a fun challenge. And difficult due to indentation considerations. You can find my contact info on my github page.

I think it'll be pretty deep down in the parser.

Thanks for the shoutout to Toffee, @aseemk . Not too many people know about it...yet :-)

+1 This is one thing that I can't easily get over.

For anyone still wishing for this, ECT http://ectjs.com/ is still rather actively developed, and open to feature suggestions. Wrote a ST2/TM .tmLanguage for it too. Has multiline capabilities, and is much much faster than ECO.

[gbouthenot]

thank for these 2 alternatives : http://ectjs.com/ https://github.com/malgorithms/toffee

Unfortunately, none of these solutions are (yet) supported by Ruby on Rails.

what is needed to get some of the alternatives up and running? dived a little into ECO's gemfile and won't pretend to completely understand. ;)

[cweezy]

+1.There's cases where I just want a few lines for an if/else or something.
