Hi All

I not talking about import
/templates/modules/something.py
or
/templates/modules/something.html

I am talking about pypi packages.

Could you give a easy example like:

easy_install jsmin

## /templates/myminimizer.mako
<%namespace name="hw" file="/jsmin/__init__.py" import="*" /> NOT WORKING
<%namespace name="hw" module="jsmin" /> NOT WORKING
<%
import jsmin ## NOT WORKING
%>

## toMinimizer is a javascript code
toMinimizer = '
    function decodeit_ve() {
            inpdata=window.document.blcoder.blinptext.value;
            passwd=window.document.blcoder.blpassword.value;
            window.document.blcoder.blouttext.value="Working...";
        if ( window.document.blcoder.bltype.options[0].selected )
            decodetext(2);
        if ( window.document.blcoder.bltype.options[1].selected )
            decodetext(0);
        // if ( window.document.blcoder.bltype.options[2].selected )
        //    decodetext(1);
            window.document.blcoder.blouttext.value=outdata;
        inpdata="";
        outdata="";
        passwd="";
        }
        '

${hw.jsmin(toMinimizer)} NOT WORKING

I tried a lot!

And I read http://www.makotemplates.org/docs/namespaces.html

from mako.runtime import supports_caller
@supports_caller

Usually I do that by importing the module into helpers.py

Then you can just call h.jsmin

Well, I don't understand what the original problem is. If he can't do
"<% import package %>" within a template, he probably can't import it
outside the template either. That suggests it was installed
incorrectly or the Python path or virtualenv is screwed up.

I think you can use <%namespace ...> to import pure Python modules,
but the functions have to be written to use Mako's special context
argument.

Mako compiles template into .py file finally, you can get it in data/template directory. So if your package can be imported correctly in your python file, you can use it in Mako too.

In above example, I first install html package using easy_install html, then import it in Mako template directly. This example works correctly in my pylons env.
