absolute path of Galaxy folder in template mako file in visualisation plugin

Question

[sureshhewabi]

Hi,

My question is how can I get the absolute path of the galaxy root folder from mako template file of the visualisation plugin? For example, /Users/myname/Downloads/galaxy is my root folder. I want this value in javaScript.

my template file has:

 <%
   root = h.url_for( "/" )
   app_root = root + "plugins/visualizations/protviewer/static/"
%>

I tried to access it in javascript like this:

var config = { root : '${root}' }
alert(config.root)

It gave me '/' but I expected /Users/myname/Downloads/galaxy. Any idea how to get this?

Asking this over at Galaxy biostars may be more appropriate (assuming PSU galaxy is what this question is referring to).
